If, however, such Work is not found to be defective, CONTRACTOR shall GC-22 E&N-78 1 71 1 be allowed an increase in the Contract Price or an extension of the i Contract Time, or both, directly attributable to such uncovering, exposure, observation, inspection, testing and reconstruction if he makes a claim therefor as provided in Articles 11 and 12. i Owner May Stop the Work: 13,8. If the Work is defective, or CONTRACTOR fails to supply sufficient skilled workmen or suitable materials or equipment, or fails to conform to the progress schedule required by Paragraph 14.1, or if CONTRACTOR fails to make prompt payments to Subcontractors or for labor, materials or equipment, OWNER may order CONTRACTOR to stop the Work, or any portion thereof, until the cause for such order has been j eliminated; however, this right of OWNER to stop the Work shall not give rise to any duty on the part of OWNER to exercise this right for the benefit of CONTRACTOR or any other party, 4 Correction or Removal of Defective Work: 13.9. If required by ENGINEER prior to approval of final payment, CONTRACTOR shall promptly, without cost to OWNER and as specified by ENGINEER, either correct any defective Work, whether or not fabricated, installed or completed, or, if the Work has been rejected by ENGINEER, remove it from the site and replace it with nondefective Work. If CONTRACTOR does not correct such defective Work or remove and replace such rejected Work within a reasonable time, all as specified in a written notice from ENGINEER, OWNER may have the deficiency corrected or the rejected Work removed and replaced. All direct or indirect costs of such correction or removal and replacement, including compen- sation for additional professional services, shall be paid by CONTRACTOR, and an appropriate deductive Change Order shall be issued, CONTRACTOR shall also bear the expenses of making good all Work of others destroyed or damaged by his correction, removal or replacement of his defective Work. I { One Year Correction Period: ' 13,10, If, after the approval of final payment and prior to the r" expiration of one year thereafter or such longer period of time as may be prescribed by law or by the terms of any applicable special guarantee required by the Contract Documents, any Work 's found to be defective, CONTRACTOR shall promptly, without cost to OWNER and in accordance with OWNER's written instructions, either correct such E defective Work, or, if it has been rejected by OWNER, remove it from the site and replace it with nondefective Work, If CONTRACTOR does r promptly comply with the terms of such instructions, OWNER may .aye the defective Work corrected or the rejected Work removed and F&N-78 GC-23 5 E f ~j replaced, and all direct and indirect costs of such removal and re- placement, including compensation for additional professional services, shall be paid by CONTRACTOR. Acceptance of Defective Work; 13.11. If, instead of requiring correction or removal and replace- ment of defective Work, OWNER prefers to accept it, he may do so. In such case, if accepptance occurs prior to approval of final payment, a Change Order shall be issued incorporating the necessary revisions in the Contract Documents, including appropriate reduction in the Con- tract Price; or, if the acceptance occurs after approval of final pay- ment, an appropriate amount shall be paid by CONTRACTOR to OWNER. i Neglected Work by Contractor, 13.12, If CONTRACTOR should fail to prosecute the Work in accordance with the Contract Documents, including any requirements of the progress schedule, OWNER, after seven (7) days' written notice to CONTRACTOR ' may, without prejudice to any other remedy he may have, make good such deficiencies and the cost thereof (including compensation for additional professional services) shall be charged against CONTRACTOR in which i case a Change Order shall be issued incorporating the necessary revisions in the Contract Documents including an appropriate reduction in the Contract Price. If the payments then or thereafter due CONTRACTOR are not sufficient to cover such amount, CONTRACTOR shall pay the dif- ference to OWNER. ARTICLE 14 - PAYMENTS AND COMPLETION s Schedules, 14.1. At least ten (10) days prior to submitting the first Appli- cation for a progress OR shall submit a progress schedule, payment, CONTRACT a final schedule of Shop Drawing submission and a schedule of values of the Work. These schedules shall be satisfactory in form and sub- stance to ENGINEER. The schedule of values shall include quantities and unit prices aggregating the Contract Price, and shall subdivide the Work into component parts in sufficient detail to serve as the basis for progress payments during construction. Upon approval of the schedules of values by ENGINEER, it shall be incorporated into the form of Application for Payment furnished by ENGINEER. Application for Progress Payment, 14.2. At least ten (10) days before each progress payment falls due (but not more often than once a month), CONTRACTOR shall submit to !j I F&N-73 GC-24 V 1 A 5 ENGINEER for review an Application for Payment on a form supplied by the OWNER filled out and certified by CONTRACTOR covering the Work completed as of the date of the Application. If payment is requested on the basis of materials and equipment not incorporated in the Work but delivered and suitably stored at the site, the Application for Payment shall also be accompanied by such data as required by OWNER, Each subsequent Appli- cation for Payment shall also include an affidavit of CONTRACTOR stating ' that all previous progress payments received on account of thF Work have been applied to discharge in full all of CONTRACTOR's obligation- reflected in prior Applications for Payment. The CONTRACTOR shall cert'fy on each Application for Payment that the Work performed to date complies with the Contract Documents, ~ Contractor's Warranty of Title: 14.3. CONTRACTOR warrants and guarantees that title to all Work, materials and equipment covered by any Application for Payment, whether f incorporated in the Protect or not, will pass to OWNER at the time of payment free and clear of all liens, claims, security interests and encumb- rances (hereinafter in these General Conditions referred to as "Liens"). S Approval of Payments, 14.4• ENGINEER will, within ten (10) days after receipt of each Application for Payment, either indicate in writing his approval of payment and present the Application to OWNER, or return the Application to CONTRACTOR i indicating in writing his reasons for refusing to approve payment. In the latter case, CONTRACTOR may make the necessary corrections and resubmit the Application. OWNER shall, within ten (10) days of presentation to him of the approved Application for Payment, pay CONTRACTOR the amount approved by ENGINEER less ten (10%) percent of the amount thereof which shall be retained until Final Payment and less all other sums that may be retained by the OWNER as set forth in the Contract Documents, 14.5. ENGINEER's approval of any payment requested in an Application for Payment will constitute a representation by him to OWNER, based on ENGINEER's on-site observations of the Work in progress as an experienced and qualified design professional and on his review of the Application for Payment and the accompanying data and schedules that the Work has progressed to the point indicated, that, to the best of his knowledge, information and belief, the quality of the Work is in accordance with the Contract Documents (subject to an evaluation of the Work as a functioning Project upon Substantial Completion, to the results of any subsequent tests called for in the Contract Documents and any qualifications stated in his approval); and that CONTRACTOR is entitled to payment of the amount approved, However, by approving any such payment ENGINEER will not thereby M-78 GC-25 J 1 i j I be deemed to have represented that he made exhaustive or continuous on- site inspections to check the quality or the quantity of the Work, or that he has reviewed the means, methods, techniques, sequences, and pro- cedures of construction, or that he has made any examination to ascertain how or for what purpose CONTRACTOR has used the moneys paid or to be paid to him on account of the Contract Price, or that title to any Work, ` materials or equipment has passed to OWNER free and clear of any Liens. f 14.6, ENGINEER may refuse to approve the whole or any part of any payment if, in his opinion, it would be incorrect to make such representations to OWNER. He may also refuse to approve any such payment, or because of subsequently discovered evidence or the results of subsequent inspections or tests, nullify any such payment previously approved, to such extent as may be necessary in his opinion to protect OWNER from loss because; 14.6.1, the Work is defective, or completed Work has been damaged requiring correction or replacement, 1 14.6.2, claims or Liens have been filed or there is reason- able ca, n to ',nlieve such may be filed, 14.6.., the Contract Price has been reduced because of Modifications, 14.6.4. OWNER has been required to correct defective Work {I or complete the Work in accordance with paragraph 13,11 or { 14.6.5, of unsatisfactory prosecution of the Work, including failure to furnish acceptable submittals or to clean up. 14.6.6, reasonable indication that the Work will not be completed within the Contract Time , E 14.6.7, reasonable doubt that the Work can be completed for 0, the unpaid balance of the Contract Price. Substantial Completion; 14.7. Prior to final payment, CONTRACTOR may, in writing to OWNER and ENGINEER, certify that the entire Project is substantially complete and request that ENGINEER issue a certificate of Substantial Completion. Within a reasonable time thereafter, OWNER, CONTRACTOR and ENGINEER shall make an inspection of the Project to determine the status of completion, If ENGINEER does not consider the Project substantially complete, he will notify CONTRACTOR in writing giving his reasons therefor. If ENGINEER considers the Project substantially complete, he will prepare and deliver F&N-78 GC-2f r { 1 J 4 i to OWNER a tentative certificate of Substantial Completion which shall fix the date of Substantial Completion and the responsibilities between OWNER and CONTRACTOR for maintenance, heat and utilities. There shall be attached to the certificate a tentative list of items to be completed or corrected before final payment, and the certificate shall fix the time within which such items shall be completed or corrected, said time " to be within the Contract Time. OWNER shall have seven (7) days after receipt of the tentative certificate during which he may make written objection to ENGINEER as to any provisions of the certificate or attached list, If, after considering such objections, ENGINEER concludes that the Project is not substantially i,;ete, he will within fourteen (14) days after submission of the ten~at ve certificate to OWNER notify CONTRACTOR In writing stating his reasons therefor. If, after consideration of OWNER's objections, ENGINEER considers the PROJECT substantially complete, ! 1 1 he will within said fourteen (14) days execute and deliver to OWNER and f CONTRACTOR a definitive certificate of Substantial Completion (with a revised tentative list of items to be completed or corrected) reflecting such changes from the tentative certificate as he believes justified after consideration of any objections from OWNER, The failure of the 1 ENGINEER to include any items on such tentative list of items to be completed does not alter the responsibility of the CONTRACTOR to complete all Work in accordance with the Contract Documents. 14.8. OWNER shall have the right to exclude CONTRACTOR from the Project after the date of Substantial Completion, but OWNER shall allow CONTRACTOR reasonable access to complete or correct items on the tentative list. Partial Utilization; } 14.9. Prior to final payment, OWNER may request CONTRACTOR in writing ' to permit him to use a specified part of the Project which he believes he may use without significant interference with construction of the other parts of the Project. If C014TRACTOR agrees, he will certify to OWNER and ENGINEER that said part of the Projec`, is substantially com- plete and request ENGINEER to issue a certificate of Substantial Completion for that part of the Project, Within a reasonable time thereafter OMi~ R, i CONTRACTOR and ENGINEER shall make an inspection of that part of the I Project to determine ins status of completion, If ENGINEER does not consider that it is substantially complete, he will notify OWNER and CONTRACTOR in writing giving his reasons therefor, If ENGINEER considers that part of the Project to be substantially complete, he will execute and deliver to OWNER and CONTRACTOR a certificate to that effect, fixing the date of Substantial Completion as to that part of the Project, at- taching thereto a tentative list of items to be completed or corrected before final payment and fixing the responsibility between OWNER and y is&N-78 GC-27 1 r heat and Itilities as to that part of the from any CONTRACTOR for maintenance, com- project.

If the unpaid balance of the Contract Price exceeds the direct and indirect costs of completing the Project, Including compensation for additional professional services, such excess shall be paid to CONTRACTOR. Y~ If such costs exceed such unpaid balance, CONTRACTOR shall pay the difference to OWNER. Such costs incurred by OWNER shall be determined by ENGINEER and incorporated in a Change Order. M 15.3.

It shall be the responsibility of the hidder to make such subsurface investigations as he deems necessary to determine the nature of material to be excavated, 1.04 CORRECTION PERIOD Nothing in the General Conditions Article 13 concerning the correction period shall establish a period of limitation with 1 respect to any other obligation which Contractor has under the Contract Documents. The establishment of time periods relates only to the specific obligations of Contractor to correct the work, and has no relationship to the time within which his i obligations under the Contract Documents may be sought to be enforced, nor to the time within which pru,;eedings may be commenced to establish his liability with respect to his obli• gations other than to specifically correct the work. This correction period shall be covered by the extension of the Per- formance Bond. 1,05 CONNECTIONS TO EXISTING FACILITIES It will he necessary, during the course of construction, to make several connections to the existing wastewater collection system, All work involved in making connections which will require a shutdown 1 of any components of the existing system shall be carefully planned and coordinated with both the Engineer and the Owner so that "down" time of the existing system may be held to a minimum. On occasions when the existing system is down for purpose of mat.-iny a connection, work shall proceed on a 24-hour schedule until the wastewater collection system is back in operation, I 01001-1 I i 1.06 WORKMANSHIP 1 These specifications contain detail instructions and descriptions ' covering the major items of construction and workmanship necessary for building and completing the various units or elements of the j project. The specifications are intended to be so written that only first class workmanship and finish of the best grade and quality will result. The fact that these specifications may fail i to be so complete as to cover all details will not relieve the Contractor of full responsibility for providing a completed project of high quality, first class finish and appearance and satisfactory for operation, all within the apparent intent of the j plans and specifications. 1.07 SANITATION FACILITIES The Contractor shall provide portable toilet facilities (Chem-cans) in sufficient number for the Contractor's use throughout the course of the project and in accordance with OSHA requirements. 1.08 SALVAGED MATERIAL { During construction of the project any equipment or materials which have been the property of the Owner and which is salvaged by the Contractor shall remain the property of the Owner, Brick and concrete rubble shall be the property of the Contractor and shall j be disposed of off the plant site. 1.09 MATERIALS These specifications are intended to be so written that only materials of the best quality and grade will be furnished. The fact that the specifications may fail to be sufficiently complete in some detail will not relieve the Contractor of full respon- sibility for providing materials of high quality and protecting them adequately until incorporation in the structure. The specifications for materials set out the minimum standard of quality which the Owner believes necessary to procure a satis- factory project. No substitutions will be permitted until the Contractor has received written permission of the Engineer to make a substitution for the material which has been specified, Where the term "or equal", or "or approved equal" is used, it is understood that if a material, product, or piece of equipment of the specified name and quality is furnished it will be approvable, as the particular name was used for the purpose of establishing a standard of quality acceptable to the Owner. If a product of any 4 other name is proposed for use, the Engineer's approval thereof must be obtained before the proposed substitute is procured by the Contractor. Wherever the term $or equal" is used, it is under- stood to mean "or approved equal", 01001-2 ti { 7 Y' 1.10 COST BREAKDOWN Within thirty (30) days after the execution of the Contract, and not less than ten (10) days prior to the first monthly estimate, the Contractor shall submit to the Engineer a cost breakdown of the work under this Contract. This breakdown is for use by the F Engineer in preparing the monthly estimates and for the Owner's use in cost accounting for the project. The breakdown shall be in detail, itemizing all items of equipment and construction and shall accurately reflect the cost of all work as included in the bid prices. Cost breakdown shall be such that an overall cost of the various elements of the project can be determined. 1.11 PROGRESS SCHEDULES Within 10 days prior to submission of first monthly progress payment, the Contractor shall prepare and submit to the Engineer for approval six copies of the schedule in which the Contractor proposes to carry on the work the date of which he will start the several major ta, activities including procurement of materials, and equipment) and the contemplated dates for completing the same. The schedule shall ' be in the form of a progress chart of suitable scale to indicate graphically the percentage of work scheduled for completion at any time. As the work progresses, the Contractor shall enter on the chart the actual progress at the end of each partial payment period or at such intervals as directed by the Engineer. The Contractor shall also revise the schedule to reflect any adjustments in contract time approved by the Engineer. Three copies of the updated schedule I shall be delivered at such intervals as directed by the Engineer. If, in the opinion of the Engineer, work accomplished falls behind ' ' that scheduled, the Contractor shall take such action as necessary E to improve his progress. In addition, the Engineer may require the Contractor to submit a revised schedule demonstrating his h , program and proposed plan to make up lag in scheduled progress and to insure completion of the work within the contract time. If the Engineer finds the proposed plan not acceptable, he may require the Contractor to increase the work force, the construction plant and equipment, the number of work shifts or the overtime opera- tions without additiona. cost to the Owner. Failure of the Contractor to comply with these requirements shall be considered grounds for determination by the Engineer that the k, Contractor is failing to prosecute the work with such diligence as will insure its completion within the time specified. 1.13 TESTS In addition to the tests called for in the Specifications, the b Owner may rifle tests made of pipe and materials for conformity g with the Specifications by an independent testing laboratory. 01001-3 4 ' r i j Such independent laboratory will be selected and paid by the Owner.

Joints or splices where required shall be made with minimum 2" wide tape equivalent to the material being joined or spliced, 03300-8 top, r i ,ranular fill WON the vapor barrier shall be smoothed and any protrusions that might damage or rupture the polyethylene film shall be eliminated, Completely cover porous fill with film. Lap film not less than 6" at all i joints, with the top placed in the direction of spread- ing of the concrete, Use pressure sensitive tape at all t _ laps of vapor barrier. Lap reinforcement directly over film prior to placing concrete, taking precautions to prevent film punctures. Carefully cut film around pipes and wiring outlets, and then apply pressure sensitive tape around these protrusions to insure maximum barrier effectiveness. 2.02 CONCRETE PROPORTIONS r A. GENERAL. y ACI 211.1 shall be the basis for selecting the proportions for concrete made with aggregates of normal and high density and of workability suitable for usual cast-in-place struc- tures. B. PROCEDURE IN DESIGN OF CONCRETE MIXES 1, General; The Contractor shall be responsible for the design of the concrete consistent with the minimum requirements of strength and proportions stated herein. The proportions of materials entering into the mix, subject to limitations already stated, to produce concrete of satisfactory quality, shall be determined by j laboratory tests prior to beginning of concrete placing, Design shall be in accordance with ACI Standard 211.1 "Recommended Practice for Selecting Proportions of Concrete," subject to maximum water cement ratio, minimum cement content and minimum strengths set forth herein. 2. Trial Mixes; An independent testing laboratory retained by the Contractor and approved by the Owner shall deter- mine the materials and proportions for trial concrete mixes to meet the requirements of this specification. The laboratory trial concrete mix design shall be submitted for the Engineer's approval before the 7-day strength tests are made. Laboratory samples shall be made in accordance with the trial mix designs for laboratory testing purposes. The fresh concrete shall be tested for Slump (ASTM-C143) and Air Content (ASTM-C173/C231), Strength test specimens shall be made, cured and tested for 7 and 28 day strength in accordance with ASTM-C192, ASTM-C39, ASTM-0293. 03300-9 i Laboratory tests on trial mixes shall show a 28-day strength 10 percent higher than the stated minimum 28day strength. From these preliminary tests, the ratios between 7-day and 28-day strengths shall be established to determine at 7 days the strengths necessary to satisfy the required 28-day strengths. The 7-day trial mix strength test results shall be submitted at least 14 days in advance of the 28-day strength tests. The final results of the laboratory tests of the trial mixes shall be submitted to the Engineer at least 10 days prior to the beginning of concrete placement. h 3. Changes in Mixes: If, during the progress of the work, it is found impossible to secure concrete of required workability and strength with the materials being furnished by the Contractor, the Engineer may order changes in proportions or materials or both, necessary to secure the desired properties, subject to limitations alraady stated. The Contractor may not make changes in ! materials, either gradation, source, or brand, or proportions of mixtures after their having once been approved except by specific written approval of the ! Engineer. f C. WORKABILITY q In general the workability of any mix shall be that required { for the specific placing conditions and method of placement. The concrete shall be of such workability that it can be worked readily into all corners and around reinforcing without segregation of materials or having free water collect on the surface. Compliance with specified slump limitations shall not necessarily designate a satisfactory mix. The Engineer may require changes in proportions at any time as necessary to obtain a mix having satisfactory properties. The slump tests will be made by the Engineer (or a designated representative of the Owner's laboratory) in accordance with ASTM Method of Test for Slump of Portland Cement Concrete, Designation C-143. In no case shall the amount of coarse material be such as to produce harshness in placing or honeycombing in the structure when forms are removed. i 03300-I0 D.

QUALITY ASSURANCE 1. Laboratory Service: The control of design, propor- tioning, mixing, and testing of all materials, ready mix, transit mix or central plant concrete shall be under the supervision of the Owner's Testing Laboratory. A representative of the Laboratory will work in coope- ' 03300-11 ration with the Contractor and the Engineer and will furnish to the Engineer and Contractor a summary of all tests which are performed. No concrete shall be placed without a representative of the Laboratory being present either at the plant or at the project site. a. Small Placements: For concrete placements of ten cubic yards or less, the Engineer may waive these requirements; however, in such event, evidence shall be furnished showing a design mix to meet the requirements of the specifications, a b. Cost of Laboratory Service; Unless otherwise specified, all cost for laboratory service except those tests in connection with the mix design and trial batches at the beginning of the project shall be borne by the Owner. Cost of mix design and tests as required for initial batch designs shall be paid for by the Contractor. F. TESTS OF CONCRETE 1. General: Frequent tests will be required by the Engineer throughout the work to determine the quality of concrete. Unless otherwise specified these tests shall be made by an independent testing laboratory to be selected and paid for by the Owner. All samples shall be taken in accordance with ASTM C172. 2, Slump Test: The slump test as described in ASTM C143 will be used to indicate workability and consistency of the concrete mix from batch to batch. Generally, a slump test will be made at the start of operations each day, at regular intervals throughout a working day, and at any time when the appearance of the concrete suggests a change in uniformity, k 3, Air Content Test: Tests for air content of the concrete r shall be made in accordance with ASTM C231, at the point of delivery of concrete gust prior to placing in forms. The test shall be made often enough to insure a proper air content uniform from batch to batch, 4, Compression Test: Compression test specimens shall be 6" x 12" concrete cylinders made and cured according to the latest designation of ASTM C31. The number of specimens and frequency of sampling shall be determined by the Engineer. No fewer than two specimens shall be made for each test to be made at each age (7 and 28 days), and samples shall be taken at a minimum of every 160 cubic yards of concrete of each class placed, Further, at least one set of test specimens per day 03300-12 I shall be made of each class of concrete used that day. All specimens shall be cured under laboratory conditions specified in ASTM C31. Additional concrete cylinders may be required to be cured on the job under the actual job curing conditions-, this shall be the Contractor's responsibility. These samples could be required when: ! a. In the opinion of the Engineer, there is a possi- bility of the air temperature surrounding the concrete falling below 40 degrees F., or rising above 90 degrees F. b. In the opinion of the Engineer, the curing pro- cedure may need improving and/or lengthening. C. Necessary to determine when structure may be put in service. i Compression strength tests shall be made on the labora- tory cured and Job cured concrete cylinders at 7 and 28 days, in accordance with ASTM C39, latest designation. The value of each test result shall be the average compressive strength of two samples taken at the same time from the same batch of concrete. The tests made it j 7 days shall show strengths of not less than two-thirds (2/3) of the design strength. For the 28 day cylinders, the strength level will be considered satisfactory if the averages of all sets of three consecutive strength ' test results exceeds the required design compressive 1 strength, f'c, and no individual strength test result falls below the required f'c, by more than 500 psi. If the test record of the standard-cured specimens fails to satisfy the strength requirements, the Engineer shall have the right to order a change in the mix proportions. If the ,fob-cured cylinders fail the strength criteria, ! the Engineer shall have the right to require changes in temperature, moisture conditions, and time for the curing process to obtain the required strength. If a i strength deficiency exists as shown by either test record, the questionable portion of the structure shall ~ be cored, tested and evaluated according to AC[ 301. ~ The cost for testing of the hardened concrete structure and possible subsequent replacing of a part of it found ; 1 to be inadequate shall be at the Contractor's expense. Unless the Owner's laboratory is on the site, the Contractor shall provide such housing as may be required for curing and storage of test specimens and testing equipment. The Contractor, if he desires, may at his 03300-13 i expense, have tests made of cylinders as a check on the tests made for the Owner, 5 Failure to Meet Requirements: Should the 7-day strengths shown by the test specimens fall below the required values, the Engineer shall have the authority to require additional curing on those portions of the structures represented by the test specimens. The additional curing required by the Engineer shall be done at the Contractor's expense, and test cores shall be } obtained and tested in accordance with ASTM Method of Obtaining and Testing Specimens from Hardened Cores and Beams of Concrete, Designation C42. In the event that such additional curing does not give the strength required, the Engineer shall have the right to require strengthening or replacement, at the Contractor's expense, of those portions of the structure which failed to develop the required strength. [ Upon receipt of written request by the Contractor, substandard concrete work may be re-examined in place by non-destructive testing methods or core samples in accordance with ACI 301. The Contractor shall retain the services of an independent testing laboratory approved by the Engineer and shall bear all expenses without compensation from the Owner, Laboratory results shall be evaluated by the Engineer and the Engineer shall make the final decision on acceptability of the concrete in question. The Owner may withhold payment for any section of concrete that does not meet the requirements of these specifications for placement, lines, finishing, general workmanship or strength. Withheld payment shall be based on the unit prices bid for additional concrete and reinforcing steel. Payment shall be withheld until the unacceptable concrete has been refinished, removed and replaced or otherwise brought into conformance with the specifications. G. MIXING CONDITIONS 1. General: The concrete shall be mixed in quantities required for immediate use, and any concrete which is not in place within the time limits specified in paragraph GA shall not be used. Retempering of concrete will not be permitted, 2, Concrete Temperature: No concrete shall be placed when { the temperature of the concrete to be placed is greater than 90 degrees F. or less than 50 degrees F. The E temperature of the concrete to be placed will be taken 03300-14 i i I l ~ by the Engineer using a thermometer immediately prior to placement with the point of measurement being in the I chute or bucket. 1 3. Cold Weather; No concrete shall be mixed without the approval of the Engineer when the air temperature is at authorized away tfrom falling. i If the shade or below artificial O heat) degrees and F. (taken he art Engineer, concrete may be mixed when Oe air temperature is at 35 degrees F. and rising. All cold weather 3 concreting shall be done in accordance with ACI-306. When permission is given for mixing when the air temperature is below 40 degrees F., all water used for mixing shall be heated to a temperature sufficient to raise the temperature of concrete to 70 degrees F., but the temperature of the mixing water shall not exceed 165 degrees F. at the time of entering the mixer. If heating the mixing water only will not raise: the placing temperature of the concrete to 70 degrees then the ~ aggregate must also be heated, either by s`,eam or dry heat, to a temperature sufficient to raise the placing temperature of the concrete to the required temperature. In no case shall the aggregate temperature as it enters the mixer exceed 150 degrees F. The heating apparatus shall be such as to heat the mass of the aggregate i uniformly and preclude the occtirrence of hot spots which I will burn the material. Temperatures of transported concrete shall not be less than 60 degrees F. at the I time of placing in the forms.* Salts, chemicals or other foreign materials shall not be mixed with the concrete for purpose of preventing freezing. *Adequate means shall be provided to maintain the l concrete and the surrounding air at a minimum tem- it perature of 50 degrees F. for a minimum of 3 days. 4. Hot Weather: Hot weather is defined as any combination of high air temperature, low relative humidity and wind velocity that in the Judgment of the Engineer would impair the quality of the concrete. All hot weather concreting shall be in accordance with ACI-305. Concrete shall be placed in the forms without the addition of any more water than required by the design (slump). No excess water shall be added on the concrete surface for finishing. Control of initial set of the concrete and extending the time for finishing operations may be accomplished with the use of an approved water-reducing and set-retarding admixture as specified above. 03300-15 V 7T i Maximum time intervals between the ad water and/or cement to the batch, andtheoPlacingxofg concrete in the forms shall not exceed the following; / Air or Concrete Temperature (whichever higher) Addition xofuWateretorPlacement Non-Agitated Concrete Up to 80° F. 30 Minutes Over 80° F. 15 Minutes Agitated Concrete Up to 75° F. 90 Minutes 75° to 89° F. Over 90° F, (max, permissible 60 Minutes concrete temperature) 45 Minutes The use of an approved set-retarding admixture will permit the extension of the above time maximums by 30 minutes, for_ agitated concrete one. Under extreme hot temperature, wind, or humidity conditions, the Engineer may require the use of the set-retarding agent, or may suspend concreting ope- rations if quality of the concrete being placed is not acceptable. 2.03 BATCNING, MEASURING AND MIXING A. GENERAL I If operated on the Job site, the batching plant shall be located in an area approved by the Engineer. Separate bins or compartments shall be provided for each size or classification of aggregate and for bulk Portland cement when used. The compartments shall be of ample size and so constructed that there is no mixing or mingling of the materials being batched during operations, The batching plant shall be equipped so that the flow of each material into the batcher is stopped automatically when the designated weight has been reached, Aggregate may be weighed in sepa- rate weigh batchers with individual scales, or cumulatively in one weigh batcher on ons scale. Bulk Portland cement shall be weighed on a separate scale in a separate weigh batcher, Water may be measured by weight or by volume, if measured by weight, it shall not be weighed cumulatively with another ingredient, Batrhing controls shall be so inter- locked that the charging mechanism cannot be opened until the 03300-16 r t scales have returned to zero. These requirements can be satisfied by a semiautomatic batching system as defined in the Concrete Plant an ar s o the toncre~e Plant Manu- facturer's Bureau, Sixth Revision, (Dec. 1, 1977) with interlocking as described above, or by an automatic batching system as defined in the Concrete Plant Standards--The p-ian't shall -be arranged so as to facilitate the inspection of all operations at all times. Suitable facilities shall be provided for obtaining representative samples of aggregate from each of the bins or compartments for test purposes. Delivery of materials from the batching equipment shall be within the following limits of accuracy: ` Material Percent Cement I Water I Aggregate 2 r Admixtures 3 I F When aggregates are weighed cumulatively, the limit for aggregate applies to the total weight in the batcher after each aggregate size has been batched. B. WATER BATCHER AND ADMIXTURE DISPENSER 4 2 Equipment for batching water and the air-entraining admixture a shall be provided at the batching plant or included with the paving mixers or truck mixers as required for the type of plant used, C. WATER BATCHERS A suitable water measuring device shall be provided which will be capable of measuring the mixing water within the ► specified requirements for each batch. The mechanism for delivering water to the mixers shall be such that leakage will not occur when the valves are closed. The filling and discharge valves for the water batcher shall be so inter- locked that the discharge valve cannot be opened before the filling valve is fully closed. ' I D. ADMIXTURE DISPENSER A suitable device for measuring and dispensing the air-en- training admixture shall be provided. The device shall be capable of ready adjustment to permit varying the quantity of admixture to be batched. The dispenser for air-entraining admixtures shall be interlocked with the batching and dis- charging operations of the water so that the batching and discharging of the admixture will be automatic. 03300-17 t 1 i E, MOISTURE CONTROL The plant shall be capable of ready adjustment to compensate for the varying moisture contents of the aggregate, and to change the weights of the materials being batched. An electric moisture meter shall be provided for measurement of moisture in the fine aggregate. The sensing element shall be arranged so that the measurement is made near the batcher ( charging gate of the sand bin or in the sand batcher. F. SCALES Adequate facilities shall be provided for the accurate , measurement and control of each of the materials entering each batch of concrete. The accuracy of the weighing equip- ment shall conform to the applicable requirements of National Bureau of Standards Handbook 44 for such equipment, The Contractor shall provide standard test weights and any other auxiliary equipment required for checking the operating performance of each scale or other measuring device. Peri- odic tests shall be made in the presence of the Engineer in such a manner and at such intervals as may be directed. Upon completion of each check test and before further use of the indicating recording or control devices, the Contractor shall make: such adjustments, repairs or replacements as may be required to secure satisfactory performance. Each weighing unit shall include a visible springless dial which shall indicate the scale load at all stages of the weighing opera- tion, or shall include a beam scale with a beam balance indicator which will show the scale in balance at zero load and at any beam setting. The indicator shall have an over and under travel equal to at least 5 percent of the capacity t of the beam, The weighing equipment shall be arranged so that the plant operator can conveniently observe all dials or indicators. i i G. RECORDERS An accurate recorder or recorders shall produce a graphical or digital record of the scale reading after each of the i aggregates and cement has been batched prior to delivery to the mixer and after the batchers have been discharged (return to zero reference). The weight or volume of water shall also be recorded if batched at a central batching plant. Recor- ders shall conform to the following detailed requirements. Each recorder shall be housed in a cabinet which shall be capable of being locked. The charts or tapes shall clearly indicate the difterent types of mixes used by stamped letters, numerals, colored ink or by other suitable means. The charts or tapes shall be so 03300-1.8 77 i i r marked that variations in batch weights of each type of mix can be readily observed. The charts or tapes shall show time of day (stamped or preprinted) at intervals of not more than 15 minutes. The recorded charts or tapes shall become the property of the Owner. The recorders shall be placed in a position convenient for ` observation by the plant operator and inspector. This requirement may be deleted by the Engineer if satis- factory evidence is presented to demonstrate consistent performance of the plant. H. MIXING AND MIXING EQUIPMENT Mixers may be stationary mixers, truck mixers, or paving 4 mixers of approved design. Mixers shall be capable of combining the materials Into a uniform mixture and of dis- charging this mixture without segregation. Stationary and paving mixers shall be provided with an acceptable device to loCK the discharge mechanism until the required mixing time j has elapsed. Truck mixers shall be equipped with accurate i revolution counters. The mixers or mixing plant shall include a device for automatically counting the total number i of batches of concrete mixed. The miners shall be operated ` at the drum or mixing blade speed designated by the manu- facturer on the name plate. The mixing time for stationary mixers shall be based upon the ability of the mixer to produce uniform concrete throughout I i the batch and from batch to batch. For guidance purposes, j the Manufacturer's recommendations or 1 min. for l cu. yd. plus 1/4 min. for each additional cu. yd, may be used. Final mixing time shall be based on mixer performance. Mixers shall not be charged in excess of the capacity recommended by the manufacturer on the specification plate attached to the machine. When a stationary mixer is used for partial mixing of the concrete (shrink mixed) the mixing time in the stationary mixer may be reduced to the minimum necessary to intermingle the ingredients (about 30 seconds). When a truck mixer is used either for complete mixing (transitmixed) or to finish the partial mixing done in a stationary mixer, in the absence of uniformity test data, each batch of concrete shall be mixed not less than 70 nor more than 100 revolutions of the drum at the rate of rotation designated by the manufacturer of the equipment as mixing 03300.19 1 i ~i speed, If the batch is at least 1/2 cubic yard less than the rated capacity, in the absence of uniformity test data, tho number of revolutions at mixing speed may be reduced to not less than 50. Any additional mixing shall be done at the speed designated by the manufacturer of the equipment as agitating speed. When necessary for proper control of the concrete, mixing of transit mixed concrete will not be permitted until the truck mixer is at the site of the con- crete placement. Paving mixers may be either single compartment drum or multiple compartment drum type. A sled or box of suitable size shall be attached to the mixer under the bucket so as to catch any spillage of concrete that may occur when the mixer is discharging concrete into the bucket. Multiple compart- ment drum paving mixers shall be properly synchronized, and the mixing time shall be determined by including the time required to transfer the concrete between compartments of the drum. Vehicles used in transporting materials from the batching plant to the paving mixers shall have bodies )r compartments of adequate capacity to carry the materials and to deliver each batch, separated and intact, to the mixer. Except as otherwise approved, loose cement shall be trans- ported from the batching plant to the mixers in separate boxes or compartments which shall be equipped with windproof and rain-proof covers. 1. SAMPLING Suitable facilities sh0l be provided for readily obtaining representative samples of aggregate from each of the weigh i batchers for test purposes. Suitable facilities shall be I provided for obtaining representative samples of concrete for uniformity tests. All necessary platforms, tools, and equipment for obtaining samples shall be furnished by the Contractor. 3,00 EXECUTION 3.01 GENERAL CONSTRUCTION REQUIREMENTS ;j A. APPROVAL BY ENGINEER I Before starting work, the Contractor shall inform the Engi- noer fully as to the type of forms, falsework, and methods of construction he proposes to use, and as to the amount and character of equipment he proposes to use, the adequacy of which shall be subject to the approval of the Engineer, The Contractor shall submit, for the Engineer's approval, a schedule showing the sequence of concrete placements. Ap- proval of forms, falsework, and methods of construction by 03300-20 the Engineer Fhall not be considered as relieving the Con- tractor of the responsibility for the safety or correctness or from ing houtmethods the o work n in adequac of his accordance equipment, the Contract,carry- B. TIME SEQUENCE OF OPERATIONS Unless otherwise provided, the following requirements shall govern for the time sequence in which construction operations shall be carried on. Forms for walls or columns shall not be erected on concrete footings until the concrete in the footing has cured at least two curing days. Concrete may be placed in a wall or column as soon as the forms and rein- forcing steel placements are approved. Steel beams or forms and falsework for superstructures shall not be erected on concrete substructures until the concrete in the substructure has cured at least four curing days. Approved falsework required for superstructures shall not be erected until the substructure has cured 4 curing days and shall :iot be removed uritiI the superstructure has cured 7 days. The use of com- pleted portions of a structure as the site for mixing opera- tions or for storage of materials will not be permitted without the Engineer's approval. j C. EXPANSION JOINTS AND DEVICES j 1. General Requirements: Expansion Joints and devices to provide for expansion and contraction shall be con- structed where and as indicated on the Plans. All Joints constructed open, which are to be left open or filled with poured Joint material, shall be constructed using forms adaptable to loosening or early removal. In order to avoid ,lamming such forms by the expansion i action of the concrete and the consequent likelihood of j injury to the adjacent concrete, these forms shall be removed or loosened as soon as practicable after the concrete has attained its initial set. A provision for loosening the forms to permit free expansion of the concrete without the necessity for full removal is preferred, 2. Workmanship: Armored Joints shall be carefully con- structed in order to avoid defective anchorage of the steel and to avoid porous or honeycombed concrete adjacent to same. Pr•emolded materials, wherever used, i shall be anchored to the concrete on one side of the joint by means of an approved adhesive, Such anchorage r s material to fall hall be sufficient to preclude the tendency of the u o shall be exercised In thehconstructionrofuallofointshto insure that the concrete sections are completely i~ 03300-2k r i 1 separated by an open ,joint, or by the Joint materials, and to insure that the joints will be true to the outline indicated. Immediately after the removal of forms, and again where necessary after surface finish- ing, all projecting concrete shall be removed along the exposed edges of premolded materials in order to secure full effectiveness of the expansion ,joint. Where I roofing felt or premolded materials are specified for horizontal ,joints, the material shall, if practicable, extend two inches beyond the form for the top member. The projecting portion shall be subsequently trimmed to the face of the member after the forms are removed. 3. Embedded Items: Before concrete placement begins all embedded items, i.e., water stops, anchor bolts, mechanical and electrical inserts shall be checked to 4 determine that they are firmly and securely fastened at the locations shown on the plans. They must be free of oil, rust and anything else that would prevent proper bonding to the concrete. Molds, when required shall be i made by use of some easily removed material. 4. Aluminum in Contact with or Embedded in Concrete: Where aluminum anchors, aluminum shapes, or aluminum electrical conduits are embedded in concrete, all contact surfaces ti 1 shall be painted with zinc chromate primer in accordance i with United States Joint Army-Navy Specification JANP-735. The paint shall be allowed to thoroughly dry before the aluminum is placed in contact with the con- crete, I Aluminum surfaces to be placed in contact with concrete, i! wood, or masonry construction, except where the aluminum j is to be embedded in concrete, shall be given a heavy r coat of an alkali-resistant bituminous paint before installation, The bituminous paint used shall meet the R r requirements of United States Military Specification ! MIL-P-6883. The paint shall be applied as it is received from the manufacturer without the addition of any thinner. All steel or other ferrous metal to be mounted on or placed in contact with dry/cured concrete such as valve operator floor stands, electrical switchgear, etc., shall be painted on the mounting surface in accordance with PAINTING Specification for exterior metal surfaces in non-critical areas. O. CONSTRUCTION JOINTS The joint formed by placing plastic concrete in direct contact with concrete that has attained i i is initial set shall 03300-22 I i l i be deemed a construction joint. When concrete in a structure (i or a portion of a structure is specified to be monolithic, the term monolithic shall be interpreted to mean that the manner and sequence of concrete placing shall be such that construction joints will not occur, Construction joints shall be of the type and spacing shown on the plans, Addi- tional horizontal and vertical construction joints will be considered by the Engineer upon request, but shall not be used without prior written approval of the Engineer. The locations and elevations of additional construction joints shall be subject to the approval of the Engineer. Construc- tion joints shall be neatly chamfered three-eighths of an inch (3/8") as directed by the Engineer. a Unless otherwise provided, construction joints shall be square and normal to the forms. Bulkheads shall be provided in the forms for all joints except horizontal joints, Horizontal construction joints shall be prepared for re- ceiving the succeeding lift by cleaning by air-water cutting. The air-water cutting of a construction joint shall be done # at the proper time. The surface shall be exposed sound, ' clean aggregate. The air pressure supply to the jet shall be approximately one hundred (1001 pounds per square inch, and the water pressure shall be just sufficient to bring the water into effective influence of the air pressure. After cutting, the surface shall be washed until there is no trace of cloudiness of the wash water. In areas where air-water cutting cannot be satisfactorily accomplished, or in areas where it is considered undesirable by the Engineer to disturb the surface of the concrete before it has hardened, the surface shall be prepared for receiving J the next lift by wet sand blasting to remove all laitance and 1 unsound concrete immediately prior to placing of the next lift. The surface of the concrete shall be thoroughly washed after sand blasting to remove all loose material. Immediately prior to the placing of additional concrete, all forms shall be drawn tight against the concrete in place, and the surfaces of the concrete in place shall be flushed with a coating of grout mixed in the proportions of one part of cement to two parts of sand. If shown on the plans, construction joints shall be provided with concrete keyways, reinforcing steel dowels, and water- stops. The method of forming keys in keyed joints shall be such as to permit the easy removal of forms without chipping, breaking, or damaging the concrete in any manner. 03300-23 1 i E. PREPARATION OF EXISTING HARDENED CONCRETE Where new concrete or any grouting compound except epoxy grout s is to be placed in contact with existing hardened concrete, the existing surface shall be textured by chipping or other means so that an irregular surface which has a height variance of not less than 1/4-inch is created. The existing concrete shall then be treated in accordance with paragraph D. above. ll 3.02 PLACING CONCRETE A. GENERAL REQUIREMENTS 1. Preliminary Consideration: The Contractor shall notify the Engineer upon completion of various portions of the work required for placing concrete so that inspection may be made as early as is practicable. The Contractor shall also keep the Engineer informed regarding his anticipated concrete placing schedule. When all items have been found to be in order by the Engineer including lines and grades, forms, reinforcing, inserts, piping, electrical, plumbing and the Contractor's concreting materials and equipment, the Engineer will then authorize the Con- tractor to proceed. Unless authorized by the Engineer, no concrete shall be placed in any unit prior to the completion of all form-work and the placement of all reinforcement in that unit. No concrete shall be placed 1 before the completion of all adjacent operations which might prove detrimental to the concrete. Whenever it is 1 necessary to continue the mixing, placing, and finishing of concrete after the daylight hours, the site of the work shall be brilliantly lighted so that all operations are plainly visible. In general, however, concrete placing shall be so regulated as to permit finishing operations to be completed in the daylight hours. The Engineer reserves the right to order postponement of the placing operations when, in his opinion, impending weather conditions may result in rainfall or tow temperatures which will impair the quality of the finished work. In case rainfall should occur after placing operations are started, the Contractor shall provide ample covering to protect the work. 2. Cleaning Forms: At the time of placing concrete, the forms shall be clean and entirely free om all chips, dirt, sawdust, and other extraneous matter. Forms for slab, beam and girder construction shall not have tie wire cuttings, nails, matches or any other matter whatsoever which would mar the appearance of the finished construction. All forms shall be cleaned to the satis- faction of the Engineer, and kept free of foreign matter of all kinds during concrete placing. { 03300-24 a 3, Embedded Items: Before placing concrete, care shall be taken to determine that all embedded i';ems are firmly and J securely fastened in place. All embedded items shall be I thoroughly clean and free of oil and other foreign y mate,- Ial. Anchor bolts shall be set to exact locations by the use of suitable anchor bolt templates, or as otherwise showy on the plans. B. HANDLING AND TRANSPORTING Chutes, troughs, or pipes used as aids in placing concrete shall be arranged and used so that the ingredients of the concrete will not be segregated. They shall be steel or steel lined. When steep slopes are necessary, the chutes shall be equipped with baffles or made in short lengths that reverse the direction of movement. Open troughs and chutes shall extend, if necessary, down inside the forms or through holes left in the forms, and the ends of such chutes shall terminate in vertical downspouts. All chutes, troughs, and pipes shall be kept clean and free from coatings of hardened concrete by a thorough flushing with water before and after placement. Water used for flushing shall be discharged clear of the concrete in place. Non-agitating trucks shall be used only when authorized by the Engineer with due con- sideration of the length of haul, roughness of roads, and design of trucks proposed. Pumping of concrete will be permitted, subject to approval of the pumping equipment by the Engineer. The placing of concrete for floor slabs preferably shall be done by a mixing plant located off the structure. Carting or wheeling concrete batches on completed concrete floor slab will not be permitted until the slab has aged at least four curing days. Unless pneumatic tired carts are used, the carts shall be wheeled on timber planking so that the loads and impact will be distributed over the slab. Curing operations shall not be interrupted for the purpose of wheeling concrete over finished slabs. C. DEPOSITING i The method and manner of placing shall be such as to avoid the possibility of segregation or separation of the aggregate or the displacement of the reinforcement. In thin walls, drop chutes of rubber or metal shall be used, The spattering of forms or reinforcement bars shall be prevented if the concrete so spattered will dry or harden before being in- E corporated in the mass, Each part of the forms shall be filled by depositing concrete directly as near its final r position as possible. The coarse aggregate shall be worked { I back from the face and the concrete forced under and around the reinforcement bars without displacing them. Depositing large quantities at one point in the forms and running or y 03300-25 working it along the forms will not be allowed. After the concrete has taken initial set, the forms shall not be jarred or any strain placed on projecting reinforcement, Where the Contractor's operations involve the placing of concrete from above, that is, directly into an excavated area or through the completed forms, particularly in the case of walls, piers, columns, and similar structures, all concrete so placed shall be deposited through vertical drop chutes of rubber or metal of satisfactory size. Drop chutes shall be made in sections or provider in several lengths so that the outlet may be adjusted to proper heights during placing operations. Concrete shall not be dropped free more than five (5) feet. Concrete shall be placed in continuous horizontal layers with a depth of from 1 to 3 feet, depending upon the wall thickness. Each layer shall be soft when a new I layer is placed upon it, and unless otherwise specified herein or by the Engineer, not more than one hour shall elapse between the placing of successive layers of concrete in any portion of the structures included in a continuous placement. The Contractor should avoid additional construc- t1on joints other than those shorn on plans by placing required sections of piers, walls, or superstructures in one continuous operation. If excessive bleeding causes water to form on the surface of the concrete in tall forms the mix shall be made drier to reduce the bleeding. In tall walls the concrete shall be placed to a point about a foot below the top of the wall, and at least one hour, or more if specified by the Engineer, J shall be allowed for settling. Concreting should then be l] resumed and completed before set occurs, D. CONSOLIDATING 1. General,. Each layer of concrete shall be well compacted and the mortar flushed to the surface of the forms by continuous working with mechanical vibrators of an approved type. Vibrators of the type which operate by attachment to forms will be permitted only when immer- sion type vibrators cannot be used due to inaccessi- bility. The vibrators shall be applied to the concrete immediately after deposit and shall be moved throughout the Dyer of concrete just placed, and several inches into the plastic layer below, thoroughly working the concrete around the reinforcement, embedded fixtures, and into the corners and angles of the forms until the concrete is thoroughly compacted. Mechanical vibrators shall not be operated so that they will penetrate or disturb layers placed previously which have become partially set or hardened, and they shall not be used to s aid the flow of concrete laterally. 1he vibration shall be of sufficient duration to accomplish thorough r I 03300-26 1 , r y J compaction and complete embedment of reinforcement and fixtures, but shall not be done to an extent that will t cause segregation. Vibrators shall be kept constantly moving in the concrete and shall be applied vertically a at points uniformly spaced, not farther apart than the radius over which the vibrator is visibly effective. II The vibrator shall not be held in one location longer than is required to produce a liquified appearance on the surface. 2. Vibrators; Internal vibrators shall maintain a fre- quency when submerged in the concrete of not less than 6,000 impulses per minute for spuds with diameters greater than 5 inches and 10,000 impulses for smaller spuds. The intensity (amplitude) of vibration shall be sufficient to produce satisfactory consolidation. A sufficient number of vibrators (powered pneumatically or electrically) shall be used to provide one for each ten cubic yards of concrete pper hour being placed. At least one vibrator, which may be of the gasoline powered type, shall be immediately available as a standby for each two vibrators in service. The Engineer may require the Contractor to use a vibrator of larger size and power if he feels, based on observed performance, that it is necessary to produce satisfactory consolidation. All vibrators intended for regular service or standby service shall be checked and approved by the Engineer prior to the beginning of the concreting operations, E. PLACING CONCRETE IN COLD WEATHER No concrete shall be placed when the atmospheric temperature is at or below 40 degrees F. (taken in the shade away from artificial heat) and falling, unless permission to do so is given in writing by the Engineer. When such permission is E given, or in cases where the temperature drops below 40 degrees F. after the concreting operations have been started; the Contractor shall furnish sufficient canvas and frare work or other type of housing to enclose and protect the structure in such a way that the air around the forms and fresh con- crete can be kept at a temperature not less than 50 degrees F. for a period of five days after the concrete is placed for normal concrete, and for three days for high-early-strength concrete. Sufficient heating apparatus such as stoves, salamanders, or steam equipment and fuel to furnish all required heat shall be supplied. It is understood that the Contractor is responsible for the protection of concrete placed under any and all weather conditions. Permission given by the Engineer to place concrete during freezing weather will in no way relieve the Contractor of the res- ponsibility for satisfactory results. Should concrete placed under such conditions prove unsatisfactory, it shall be removed and replaced. r 03300-27 a i i F. PLACING CONCRETE IN WATER Concrete may be deposited in water only when required by the j plans or with the permission of the Engineer. The forms, j cofferdams, or caissons shall be sufficiently tight to prevent any water flowing through the space in which the concrete is being deposited. Pumping will not be permitted while the concrete is being placed, nor until it has set for at least 36 hours. The concrete shall be carefully placed in a compact mass by means of a tremie, closed bottom-dumping bucket, or other approved method that does not permit the : concrete to fall through the water without protection. The concrete shall not be disturbed after being deposited. fr Depositing shall be regulated to maintain approximately horizontal surfaces at all times. When a tremie is used, it shall consist of a tube constructed in sections having watertight connections. The means of supporting the tremie shall permit the movement of the discharge end over the entire top surface of the work and shall permit the tremie to be rapidly lowered when necessary to choke off or retard the flow. The number of times it is necessary to shift the location of the tremie, for any continuous placement of concrete, shall be held to a minimum. During the placing of concrete, the tremie tube shall be kept full to the bottom of the hopper. When a batch is dumped into the hopper, the tremie shall be slightly raised, but not out of the concrete at the bottom, until the batch discharges to the level of the { bottom of the hopper. The flow shall then be stopped by lowering the tremie. The placing operations shall be con- tinuous until the work is completed. When concrete is placed by means of the bottom-dump-bucket, the bucket shall have a capacity of not less than one-half cubic yard. The bucket shall be lowered gradually and carefully until it rests upon " i the concrete already placed. It shall then be raised very slowly during the discharge travel; the intent being to maintain as nearly as possible, still water at the point of + discharge and to avoid agitating the mixture. G. PLACING CONCRETE IN SLABS Concrete in columns, walls, and deep beams or girders shall be allowed to stand for at least one hour, or more if speci- fied by the Engineer, to permit full settlement due to consolidation before concrete is placed in the slabs they are to support. Haunches are considered as part of the slab and shall be placed integrally with them, When monolithic slabs are placed in strips, the widths of the strips, unless otherwise specified or shown, shall be such that the concrete in any one strip will not be allowed to lie in place for more than one hour before the adjacent strips are placed. Imme- diately before placing concrete, the earth cushion to receive 03300-28 r 1 concrete shall be thoroughly dampened to prevent too rapid absorption of moisture from the concrete. H. PLACING CONCRETE IN FOUNDATIONS i Concrete in deep foundations shall be placed in a manner that will avoid segregation of the aggregates or displacement of the reinforcement. Suitable chutes or vertical pipes shall i. be provided. When footings can be placed in dry foundation pits without use of cofferdams or caissons, forms may be omitted, if desired by the Contractor and approved by the Engineer, and the entire excavation filled with concrete to 1 the elevation of the top of footing, The placing of concrete 1 bases above seal courses will be permitted after the forms ! are free from water and the seal course cleaned. Any necessary pumping or bailing during the concreting operations shall be done from a suitable sump located outside the forms. 1. PLACING CONCRETE IN PIERS + Concrete placing will begin within eight (8) hours after completion of drilling and inspection of shaft. Concrete placing shall be as continuous as practicable from the beginning of placing in the bottom to the top of shaft or to construction joints as may be indicated on the plans. Time intervals will be allowed for vibrating or rodding the concrete being placed, for pulling casing, for placing forms and other operations necessarily carried on in sequence with the placing operations. J Concrete shall be placed through a suitable tremie tube to 1 prevent segregation of concrete materials and unnecessary splashing on the reinforcing steel cage. The tremie shall be made in sections to permit the discharge end to be raised as the placement progresses. The maximum allowable fall from the end of tremie for the concrete will be five (5) feet. Wherever a casing is used, the casing should extend suf- ficiently above the grade of the finished shaft to provide excess concrete to be placed for the anticipated slump due to the casing removal. Where a cap block or groundline strut is shown on the plans to be placed at the top of the drilled shaft, and the cap or strut is shown to be placed monolithic with the drilled shaft, a time interval will be allowed for placing the required form and reinforcing after any necessary casing removal, After a placement is completed, the top surface shall be cured and any construction joint area shall be treated as prescribed elsewhere in these specifications. 03300-29 "'1R These specifications are written based on the assumption that ground water can be sealed off in the foundation materials using a casing with proper procedure, with good equipment, and with personnel experienced in this type of work. It will be required that the concrete be placed in the dry in ac- cordance with the specifications if at all possible. In the event it is clearly demonstrated that ground water cannot be thelEngineereshall be agreeable etofpouthe ring uthet shaft o concrete through water providing the following procedure is followed. , 1. The bottom of the shaft hole shall be cleaned of mud, and loose material. Water shall be pumped out as much as possible immediately ahead of concrete placing to insure that the bottom is in satisfactory condition. Flowing water is not permitted, 2. The specifications, and procedure required for under water pouring of concrete will be as specified above for "Placing Concrete in Water." j 3.03 CONCRETE FINISHING A. FINISHING SLABS i 1. General: Except as elsewhere permitted in these specifications or as shown on the drawings, all slabs, platforms and steps shall be finished monolithically. The following schedule of finishes shall apply, unless otherwise specified or shown on the plans: a, Wood Float Finish: Roof slabs, valve vault and manholes, floor slabs of basins and tops of walls, { exterior slabs except working platforms. b. Steel Trowel Finish: All interior slabs and steps, c. Brush Finish: Exterior steps, walkways, and ` working platform, i 2. Screeding: As soon as concrete placing operations have been completed for a slab section of sufficient width to permit finishing operations, the concrete shall be approximately leveled and then struck off, tamped, and t screeded. The screed shall be of a design adaptable to f the use intended, shall have provision for vertical adjustment, and shall be sufficiently rigid to hold true to shape during use. The initial strike off shall leave the concrete surface at an elevation slightly above grade so that, when 03300-30 j "1C consolidation and finishing operations are completed, the surface of the slab will be at the grade elevation shown on the plans. Tamping and screeding operations shall be continued until the concrete is properly consolidated and the surface voids are eliminated. The surface shall then be brought to a smooth true alignment by means of longitudinal screeding, floating, belting, and/or other methods approved by the Engineer. When templates are used, they shall be of such design as to permit early removal in order to permit satisfactory finishing at and adjacent to the template. 3. Straightness: While the concrete is still plastic, the surface shall be straightedged by the use of a standard ten (10) foot metal straightedge. Each pass of the straightedge shall lap half of the preceding pass. All high spots shall be removed and all depressions shall be filled with fresh concrete and refloated, The checking with straightedge shall continue during the final finishing operation until the surface is true to grade and free of depressions, high spots, voids, or rough spots. The final surface shall be checked with the straightedge and ordinates measured from the face of the straightedge to the surface of the slab shall not exceed one-sixteenth inch per foot from the nearest point of contact and the maximum ordinate shall be one-eighth inch per 10 feet. a 4. Wood Float Finish: Surfaces shall be finished using a wood float to a true even plane with no coarse aggregate visible, in the initial floating, while the concrete is plastic, sufficient pressure shall be used on the i wood float to bring all excess moisture to the surface so that it can be removed. A final "light float" finish shall be given to the surface as the concrete hardens. The surface shall have a uniform appearance and shall meet the straightness requirements. 5, Steel Trowel Finish: After all surface moisture has disappeared following the initial wood float finish, surfaces shall be steel trowelled to a smooth, even, impervious finish of uniform smoothness and color, free i a from blemishes including trowel marks. 6, Brush Finish: Following the steel trowel finish, y surface of the concrete shall be brushed lightly with a soft bristled brush. 'The brush shall be kept clean and shall be dipped in water frequently so that it will be clean and wet at all times. Brushing shall be limited to that necessary to remove the glaze and produce a nonslip surface. ' 03300-31 4 i 1 7 7. Power-Machine Finish (Option): In lieu of hand finish- ing, surfaces of slabs requiring wood float finish may be finished with an approved power finishing machine, which machine shall be operated in accordance with the directions of the machine manufacturer. Following machine finishing, irregularities left by the machine shall be eliminated by hand trowelling with a steel trowel. Power machine finishing may also be used as initial step in finishing surfaces requiring steel trowel finish; however, for steel trowel finishes the entire surface shall be given its final finish by hand, using a steel trowel. Where steel trowel surfaces are to receive a floor covering, it is not required that entire surface be hand trowelled, but all irregularities left by the finishing machine shall be eliminated by hand trowelling, The preparation of surfaces for finishing by machine shall in general be as hereinbefore required for hand finishin~i. 6. Surfaces Requiring Drainage, Where indicated on the plans, slabs shall be slo pf.,i to provide drainage with 1 such slabs to have a minimum thickness of that shown on the plans. Where floor drains are shown in slabs and slope of floor is not indicated, floors shall be sloped to drain on a grade of one-sixteenth inch (1/16") per foot with a maximum total slope of one and one quarter -4 inches (1-1/4"). Thickness of slab at floor drain shall be thickness of slab as indicated on the plans. 0. Sidewalks: Sidewalks shall be given a brush finish, Sidewalks shall be "flagged" at a spacing equal to the width of the walk and edged on each side using an approved tool having a radius of approximately one- quarter (1/4") inch. 10, Finishing in Hot, Dry Weather: During periods of high temperature and/or low humidity, extreme care shall be taken in the finishing of slabs to eliminate initial shrinkage cracks. Following the initial set of concrete 1 but while the concrete is still "green", finishing shall continue as required to remove shrinkage cracks which may occur in the initial set of concrete. In hot, dry - , weather, a cement finisher shall remain on the job following normal finishing operations for a sufficient length of time to insure the removal of initial shrin- kage cracks. i I B. FINISHING OF WALLS AND OTHER SURFACES ! 1. General: All concrete shall be finished as specified hereinunder. Forms for walls, columns and sides of beams and girders under normal conditions can be removed E 03300-32 1 t I 1 in 12-24 hours and all patching, repairing, finishing and cleaning shall follow immediately after form removal and shall be completed as soon as practicable but within 7 days of form removal. Careful attention shall be given to curing as finishing progresses. i 2. Form Finish: a. No Finish: For surfaces that are not visible from inside or outside the completed structure, i.e. back of retaining walls below embankment, etc. After forms are removed tie holes and defects shall be repaired or patched, otherwise no finish is required. b. Rough Finish: All surfaces for which this finish is explicitly indicated or required shall have all tie holes and defects larger than 1/4" in width or depth patched or repaired. All fins shall be removed flush with the adJacent surface by rubbing or grindilq and rough edges shall be dressed. Other- wise surfaces shall be left with the texture im- parted by the forms, a C. Smooth Finish: Provide smooth form finish for all z concrete surfaces that are to be exposed to view. a The form facing material shall produce a smooth, hard, uniform texture on the concrete. It may be plywood, tempered concrete-form-grade hard board, metal, plastic, paper or other approved material. The arrangement of the facing material shall be orderly and symmetrical with a minimum number of seams. Tie holes and defects shall be patched and r fins shall be removed flush with the adJacent surface. 1 3. Rubbed Finish: i a. Smooth Finish: Smooth, rubbed finish shall be produced on newly hardened concrete no later than the day following form removal. Surfaces shall be wetted and rubbed with carborurdum brick or other abrasive until a uniform color and texture are produced. No cement grout may be used other than the cement paste drawn from the ' surface by the rubbing process. 1 b. Plaster Mix Finish: Areas designated to receive this 1 r finish are to receive a two (2) coat application of h THOROSEAL PLASTER MIX, 1/8" to 1/4" in thickness, in accordance with the manufacturer's recommendations. Form treatments or curing compounds shall not contain any ingredients which might stain or otherwise prevent a good l 7 .f 03300-33 3. I bond to the concrete. Do not apply when temperature is 40°F or expected to drop below 40°F within 24 hours after application. Prepare >.urface according to manufacturer's recommendations. Apply a key coat of THOROSEAL at a rate of 2 lbs. per sq. yard by brush using 1 part ACRYL 60 to 3 parts of clean water. Allow this coat to dry 5 days. Next apply a trowel coat of THOROSEAL PLASTER MIX using a solution of 1 part of ACRYL 50 and 3 parts clean water. Apply at the f rate of 4 to 6 lbs, of mix per sq. yard. Apply and cure 1 f according to manufacturer's recommendations. c. Rubber Floated Finish; Remove forms within 2-3 days. Remove ties, burrs and fins. Mix equal parts portland cement and fine sand with water to produce a stiff mortar. Apply mortar with firm rubber float or trowel ! filling and compressing the mortar into all voids. Finish with a rubber float using a swirling motion. 4. Concrete Finish Schedule; Type of Finish Location Smooth Form Finish and Exterior walls of Lift (Plaster Mix Finish) Station and Pier to 1' below finished grade Rough Finish Interior walls of Lift Station and exterior walls lower than 1' below finished grade Brush Finish Top of Lift Station, driveway slab and sidewalk N 5, Grouting Materials: a. Non-Shrink Grout - Normal Use; Pre-mixed, factory packaged, ferrous aggregate mortar grouting compound complying with CE (Corps of Engineers) CRD-C588, Type M. Products offered by manufacturers to comply with the requirements include the following; Embeco; Master Builders Company Ferrolith G; Sonneborn Irontox: Toch Brothers b. Non-Shrink Grout - Exposed Use: Pre-mixed, nonstaining, non-shrink grout shall be Embeco 636 Grout as manufactured by Master Builders Co., Sonneborn (equal model); or equal, 03300-34 1 C. Grout (Normal Shrinkage): Normal shrinkage grout for general use shall consist of one (1) part of Portland Cement (Type II for exposure to sewage and Type I for other applications) and three (3) parts of clean, first j quality sand as approved by the Engineer. All proportioning shall be on a volumetric basis. This material shall be used for grouting clarifier and thickener floors and for filling areas of the bar screen, aeration basis outlet boxes, etc., to prevent the deposition of solids. ' d. Grouting Pumping and Other Mechanical Equipment: Pumps and other mechanical equipment shall have a layer of grout (usually 1" to 3/4') between the concrete floor and the bottoms of the equipment. Grout shall be non-shrink grout as pre-mixed Embeco Grout manufactured by Master Builders, Cleveland, Ohio, Sika Grout as manufactured by Sika Chemical Corporation, or equal. All parts of engine generator units and centrifugal blower units which require grouting shall be grouted with Esco Weld 7505 epoxy grout as manufactured by Enjay Chemical + Co., Houston, Texas, Master Builders (equal model), or equal. The grout shall be mixed and placed in accordance with the manufacturer's recommendations. After mixing, the grout shall be quickly and continuously s placed to avoid overworking, segregation and breaking down of the initial set. The foundation shall be thoroughly cleaned, the forms set in place and securely anchored, with holes or cracks in forms caulked with rags, cotton waste or dry sand mixture to prevent the loss of grout, and the necessary materials and tools shall be on hand before starting grouting operations. An chor bolt 0 holes and the surface of the concrete floor shall be washed with a liberal amount of water, and any oil or grease removed with a strong, hot detergent or caustic solution. Concrete shall be damp when the grout is 1 poured, but shall not have an excess of water to dilute the grout. No machines shall be in operation in the vicinity of grouting to cause vibrations which might affect the setting of the grout. Before final set, cut back exposed edges 1/2" and refinish with plain sand cement mortar. F 3.04 CURING CONCRETE A. GENERAL REQUIREMENTS Careful attention shall be given to the proper curing of all concrete. The curing methods shall use sheet materials con- forming to ASTM C171 or membrane curing compound conforming to 1 3 d 03300-35 t i 1 j ASTM C309. Membrane curing is not permitted on surfaces to be rubbed or on surfaces on which additional concrete, mortar or terrazzo is to be applied, Unless the curing method is otherwise noted or specified the curing method shall be selected by the contractor and sub- mitted to the Engineer for approval. ` d. LENGTH OF CURING PERIOD All concrete shall be cured for a period of seven consecutive days. In cold weather, when curing may be retarded this period shall be extended until 7 "curing-days" have passed, up to a limit of 14 consecutive days, C. CURING-DAY A "curing-day" shall be any day on which the atmospheric temperature taken in the shade, or the air temperature adjacent to the concrete, remains above 50 degrees F. for at least 18 hours. D. APPLICATION 1. Sheet Curing: Sheet materials when used shall conform to the requirements of ASTM C171. They will be in contact with the entire concrete surface and shall be applied in accordance with the manufacturer's recom- mendations. All holes shall be patched and where pedestrian traffic is unavoidable, suitable walkways shall be provided to protect the sheet material. 2. Membrane Curing: Membrane curing compound shall comply + with ASTM C309 Specifications with coloring tint, i approved by the Engineer, ready for use other than stirring, and of such composition that it will remain intact as a sealing coat for 28 days. An acceptable compound shall have such sealing qualities that the moisture loss from test specimens shall not be more than three and one-half percent when tested in accordance with Method of Test for Water Retention Efficiency of Methods of Curing Concrete, ASTM Designation C156 when the sealing compound is applied at a coverage of one-hundred and fifty square feet per gallon. The sealing compound shall be sprayed on, using pressure tank type spraying equipment, and the sealing compound 1 shall he thoroughly mixed gust before and during application by either a power-operated mechanical 1 stirrer or compressed air. Curing compound shall be strained through gasoline strainer as it is poured into spraying equipment. Application of the seal coat shall be on a moist surface, shall be uniform as indicated by 03300 •.36 . i , the color, and shall be at the rate of one gallon per 150 square feet, applied in one coat on horizontal - surfaces. On vertical surfaces curing compound shall be applied uniformly in two coats at the rate of 300 square feet per gallon for each coat. The application of the curing compound shall follow immediately after j removal of forms and preparation of concrete surface as specified. Within thirty minutes after form removal on any surface to be cured by membrane, patching shall be commenced or the surface shall be kept wet by sprinkling until patching is commarred. Curing compound shall be applied lmmedial:e1j arter any patch is made unless other curing is provid,M Seal coats shall remain in place and be protected against abrasive action for a period of 28 days if in an area where 14-day curing is required and 14 days if in an area where 7-day curing is requir- ed. Seal coats on slabs shall be protected by a one-inch layer of sand or earth or by other approved , means. The protective coating shall not be placed p sooner than 24 hours after the seal coat has been r applied. Any damages to the membrane coating within the < period of time noted above shall be repaired immediately by a liberal application of the compound. 3.05 FILLING TIE HOLES After the tie rods are broken back or removed, the holes shall be filled solid with non-shrink cement-sand mortar thoroughly cleaned to remove all grease and loose particles then the mortar shall be as dry as practicable and carefully packed into the holes in small quantities. After the holes are completely filled, all excess mortar shall be struck off flush and the surface finished in such a manner as to render the filled hole as inconspicuous as poss- ible. If these patches appear to be darker than the other surface of the concrete, white cement shall be used in the mortar 99 as required. 3.06 DEFECTIVE WORK A. GENERAL Any defective work discovered after the forms have been removed shall be repaired immediately. If the surface of the concrete is bulged, uneven, or shows excess honeycombing, or form marks, which defects in the opinion of the Engineer, cannot be repaired satftfactorily, the entire section shall be removed and replaced. f ' B. PATCHING 1 Slight honeycomb and minor defects in all concrete surfaces 1 shall be patched with cement mortar mixed in the same pro- 03300-37 1' i portions of cement and fine aggregate as the original con- crete. Finished surfaces containing sand streaks or voids will not be acceptable, and shall be repaired by cutting out the unsatisfactory material and replacing it with dry pack mortar which shall be securely keyed and bonded to the old concrete and finished in such a manner as to render the jointing as inconspicuous as possible. This concrete shall be drier than the regular mixture and shall be thoroughly 'r tamped into place. Each defective area shall be cut back with pneumatic chipping tool as deep as the defect extends and in no case less than one inch. The holes shall then be i painted with an approved bonding agent, such as Darweld C, and then filled to within three-fourths inch of the surface with approved non-shrink mortar as directed by the Engineer and the remainder of the hole filled with regular dry pack mortar. Holes less than three-fourths inch deep shall be filled with non-shrink cement-sand mortar for the full depth. The surface of such patches shall then be finished as speci- fied for tie holes. All dry pack mortar shall be driven into place with suitable hammer and wooden blocks.

GENERAL After the pipe has been laid and backfilled, each section of newly laid pipe shall be subjected to a hydrostatic pressure test, For any section being tested, the pressure applied shall be such that at the lowest point in the section, the pressure shall be equal to the design pressure of the pipe or as indicated on the Plans. Each section of pipe shall be slowly filled with water and the specified test pressure, measured to the point of lowest elevation, shall be supplied by means of a pump connected to f the pipe in a satisfactory manner. The pump, pipe connec- tion, and all necessary apparatus including gauges and meters shall be furnished by the Contractor. B, PROCEDURE The Contractor may test the pipeline in sections when all the pipe in the section has been laid and all concrete blocking is at least 28 days old. The test shall be made against valves when available, or by placing temporary plugs or bulkheads in the pipe, and filling the line slowly with water. Care shall he used to see that all air vents are open during the filling. After the line, or section thereof has been completely filled, it shall be allowed to stand under a slight pressure at least 48 hours to allow the lining to absorb what water it will and to allow the escape of air from any air pockets. During this period, the bulkheads, valves, manholes, and connections shall be examined for leaks. If any are found, these shall be stopped or, in the case of valves in the main line or bulkheads, provision shall be made for measuring the leakage during the test, The water neces- sary to maintain the test pressure shall be measured through a meter or by other means satisfactory to the Engineer, Contractor shall furnish all necessary equipment and make tests at his expense. Before applying the specified test pressurQ, all air shall be expelled from the pipe, In the event it is necessary to expel air from high points other than where taps are pro- vided, the Contractor may tap the line for this purpose and afterward tightly plug the tap. No extra compensation will be made for these taps. Duration of test shall be four (4) hours, C, EXAMINATION UNDER PRESSURE During the last two hours of the test, the entire route of the pipeline shall be inspected to locate any leaks or breaks. Any defective ,points, cracked or defective pipe, 15062-4 fittings, or valves discovered in consequence of this pros- sure test shall be removed and replaced with sound material in the manner provided and the test shall be repeated until ; satisfactory results are obtained. Any and all noticeable leaks shall be repaired regardless of whether the actual leakage is within the allowable. D, PERMISSIBIX LEAKAGE Maximum permissible leakage shall be 23.3 gallons per 24 hours, per mile of pipe, per inch of nominal diameter, based on 18 foot Joint lengths and 150 psi pressure or as specified in AWWA C600 Standard, Leakage is defined as the quantity of water to be supplied into the newly laid pipe, or any valved section of it, necessary to maintain the specified leakage test pressure i after the pipe has been filled with water and the air ex- polled. Should any test of pipe laid disclose leakage greater than that specified, the Contractor shall at his own expense, locate and repair the dofective Joints, until the leakage is within the specified allowance.
