PROSECUTION AND PROGRESS 4.01 TIMF AND ORDER OF COMPLETION: It is the meaning and intent of this contract, unless otherwise herein specifically provided, that the contractor shall be allowed to prosecute his work at such times and seasons, in such order of precedence, and in such manner as shall be most conductive to econom, of construction; provided, however, that the order and the time of prosc-cution shall be such that the work shall be substantial?.y completed as a whole and in part, in accordance with this contract, the plans And specifications, and within the time of completion designated in the Proposal; provided, also that when the Owner is having other work done, either by contract or by his own force, the Engineer may dLrect the time and mariner of constructing the work done under this contract, so chat conflict will be avoided and the construction of the various works being done for the Owner shall be harmonized. The Contractor shall submit, at such times as may reasonably be requested by the Engineer, schedules which shall show the order in which the Contractor proposes to carry on the work with dates in which the Contractor will start the several parts of the work, and estimated dates of completion of the several parts. 4.02 EXTENSION OF TIME: Should the Contractor be delayed in the completion of the work by any act or neglect of the Caner or Engineer, or of any employees of either, or by other contractors employed by the Owner, or by • 12 • changes ordered in the work, or by strikes, lockouts, fires, and unusual delays by common carriers, or unavoidable cause or causes beyond the Contractor' control, or by any cause which the Engineer shall decide justifies the delay, then an extension, of time shall be allowed for completing the work, sufficient to compensate for the delay, the amount of the extension to be determined by the Engineer; provided, however, that the Contractor shall give the Engineer prompt notice in writing of the cause of such delay. 4.03 HINDRANCES AND DEIAYS: No claims shall be made by the Contractor for damages resulting from hindrances or delays from any cause (except where the work is stopped by order of the Owner) during the progress of any portion of the work embraced in this contract. In case said work shall be stopped by the act of the Owner, then such expense as in the judgment of the Engineer is caused by such stoppage of said work shall be paid by the Owner to the Contractor. 4.04 LIQUIDATED DAMAGES: The Contractor agrees that time is of the essence on this contract, and that for each day of delay beyond the number of days herein agreed upon for the cvWpletion of the work herein specified and contracted for (after due allowance for such extension of time as Is provided for under Extension of Time hereinabove), the Owner may withhold • permanently from the Contractor's total compensation, the sum set forth in the Special Conditions or Special Provisions (or as elsewharee set forth in these Contract Documents), as stipulated liquidated damages for such delay. 5. MEASUREMENT AND PAYMENT 5.01 QUANTIFIES AND MEASUREMENTS: No ertra or customary measurements of any kind will be allowed, but the actual neasured and/or computed length, area, solid contents, number, and weight only shall be considered, unless otherwise specifically provided. 5.02 ESTIMATED QUANTITIES: This Agreement, including the specifications, plans and estimate, is intended to show clearly all work to be done and material to be furnished hereunder. Where the estimated quantities are shown for the various classes of work to be done and material to be furnished under this Contract, they are approximate and are to be used only as a basis for estimating the probable cost of the work and for comparing the proposals offered for the work. If is understood and agreed that the actual amount of work to be done and material to be furnished under this contract may differ sov"hat from these estimates, and that where the basis for payment under this contract is the unit price method, payment shall be for the actual amount of such work done and the material furnished. 13 • Where payment is based on the unit price method, the Contractor agrees that he will make no claim for damages, anticipated profits or otherwise on account of any differences which may be found between the quantities of work actually done, the material actually furnished under this contract and the estimated quantities contem- plated and contained in the proposal; provided, however, that in case the actual quantity of any item should become as much as 25% more than, or 25% less than the estimated or contemplated quantity for such items, then either party to this Agreement, upon deman6, shall be entitled to a revised consideration upon the portion of the work above or below 25% of the estimated quantity. Any revised consideration is to be determined by agreement between the parties, otherwise by the terms of this Agreement, as provided under "Extra Work". 5.03 PRICE OF WORK: In consideration of the furnishing o: all the necessary labor, equipment and material, the completion of all work by the Contractor, and on the completion of all work and of the delivery of all material embraced in this contract in full conformity with the specifications and stipulations herein con- tained, the Owner agrees to pay the Contractor the prices set forth in the Proposal hereto attached, which has been made a part of this contract. The Contractor hereby agrees to receive such prices in full for furnishing all material and all labor required for the aforesaid work, also for all expense incurred by him, and for well and truly perfurming the same and the whole thereof in the manner And according to this Agreement, the attached specifi- cations, and requirements of the Engineer. 5.04 PARTIAL PAYMENTS: On or before the 10th day of each month the Engineer shall prepare a statement showing as completely as practicable the total value of the work done by the Contractor up to and including the last day of the preceeding month. Said state- ment shall also include the value of all sound materials delivered on the site of the work that are to be fabricated into the work. The Owner shall then pay the Contractor on or before the 15th day of the current month the total amount of the Engineer's state- ment, less 10 per cent of the amount thereof, which 10 percent shall be retained until final payment and further less all previous payments and all further sums as agreed upon. It is understood, however, that in case the whole work be near to completion and some unex- pected and unusual delay occurs due to no fault or neglect on the part of the Contractor, the Owner may, upon written recommendation of the Engineer, pay a reasonable and equitable portion i of the retained percentage to the Contractor; or the Contractor, at the owner's option, may be relieved of the obligation to fully complete the work and, thereupon, the Contractor shall receive payment of the balance due him under the contract subject only to the conditions stated under "Final Payment". 5.05 USE OF COMPLETED PORTIONS: The Owner shall have the right to take possession of and use any completed or partially completed portions of the work, notwithstanding the time for completing the entire work at: such portions may not have expired, but such taking possession and use shall not be deemed an acceptance of any work not completed in accordance with the Contract Documents. If such prior use increases the cost of or delays the work, the Contractor shall be entitled to such extra compensation, or extension of time, or both, as the Engineer may determine. 5.06 FINAL COMPLETION AND ACCEPTANCE: Within ten (10) days after the Contractor has given the Engineer written notice that the work has been completed, or substantially completed, the Engineer and the Owner shall inspect the work and within said time, if the work be found to be completed or substantially completed in accordance with the Contract Documents, the Engineer shall issue to the Owner and the . Contractor his Certificate of Completion, and thereupon it shall be the duty of the Owner within the ten (10) days to issue a Certificate of Acceptance of the work to the Contractor. 5.07 FINAL PAYMENT: Upon the issuance of the Certificate of Completion, the Engineer shall proceed to make final measurements and prepare final statement of the value of all work performed and materials aurnished under the terms of the Agreement and shall certify same to the Owner, who shall pay to the Contractor on or after the 30th day, and before the 35th day, after the date of the Certificate of Completion, the balance due the Contractor under the terms of this Agreement, provided he has fully performed his contractual obligations under the terms of this contract; and said payment shall become due in any event upon said performance by the Contractor. Neither the Certificate of Acceptance nor the final payment, nor any provision in the Contract Documents, shall relieve the Contractor of the obligation for fulfillment of any warranty which may be required in the Special Conditions of the Specifications. 5.08 PAYMENTS WITHHELD: The Owner may, on account of subsequently discovered evidence, withhold or n1311ify the whole or part of Pny certificate to such extent as may be necessary to protect himself from loss on account of: • 15 • a. Defective work not remedied b. Claims filed or reasonable evidence indicating probable filing or claims. c. Failure of the Contractor to make payments properly to sub-contractors or for materials or labor d. Damage to another contractor When the above grounds are removed, or the Contractor provided a Surety bond satisfactory to the owner, which will protect the Owner in the amount withheld, payment shall be made for amounts withheld because of them. 5.09 DELAYED PAIMENTS: Should the Owner fail to make payment to the Contractor of the sum named in any partial or final statement, when payment is due, or should the Engineer fail to issue any statement on or before the date above provided, then the Owner shall pay to the Contractor, in addition to the sum shown as due by such statement, icterest thereon at the rate of six (6) per cent per annum, unless otherwise specified, from date due as provided under "Partial Payments" and "Final Payments", until fully paid, which shall fully liquidate any injury to the Contractor growing out of such delay in payment, but the right is expressly reserved to the Contractor in the event • payments be not promptly made, as provided under "Partial Payments", at any time thereafter to treat the contract as abandoned by the Owner and recover compensation, as provided under "Abandonment of Contract", unless such payments are withheld in accordance with the provisions of "Payments Withheld". 6. EXTRA WORK AND CLAIMS 6.01 EXTRA WORK: It is agreed that the Contractor shall perform all Extra Work under the direction of the Engineer when presented with a Written Work Order signed by the Engineer, subject however, to the right of the Contractor to require a written confirmation of such Extra Work Order by the Owner. It is also agreed th<<L the compensation to be paid the Contractor for performing said Extra Work shall be determined by one or more of the following methods: Method A - By agreed unit prices; or Method B - By agreed lump sum; or Method C - If neither Method A nor Method B be agreed upon before the Extra Work is commenced, then the Contractor shall be paid the "actual field cost" of the work, plus fifteen (15) per cent. 16 i~ In the event, said Extra Work be performed and paid for under Method C, then the provisions of this paragraph shall apply and the "actual field cost" is hereby defined to include the cost of all workmen, such as foremen, timekeepers, mechanics, and laborers, and materials, supplies, teams, trucks, and 7:entals on machinery and equipment, for the time actually employed or used on such Extra Work, plus actual transportation charges necessarily incurred together with all power, fuel, lubricants, water, and similar operating expenses, also all necessary incidental expenses incurred directly on account of such Extra Work, including Social Security, old Age Benefits and other payroll taxes, and a rateable proportion of premiums on Performance and Payment Bonds, and Maintenance Bonds, and on Public Liability and Property Damage, and Workmen's Compen- sation, and all other insurance as may be required by any law or ordinance, or directly by the Engineer or Owner, or by them agreed to. The Engineer may direct the form in which accounts of the "actual field cost" shall be kept and the records of these accounts shall be made available to the Engineer. The Engineer may also specify in writing before the work commences the method of doing the work and the type and kind of machinery and equipment to be used; otherwise these matters shall 1~e determined by the Contractor. Unless otherwise agreed upon, the prices for the use of machinery and equipment shall be determined by using 100 per cent, unless otherwise specified, of the latest schedule of Equipment Ownership Expense adbpted by the Associated Ceneral Contractors of America. Where practicable the terms and prices for the use of machinery and equipment shall be incorporated in the Written Extra Work Order. The fifteen (15) per cent of the "actual field cost" to be paid the Contractor shall cover and compensate him for his profit, overhead, general superinten lance, and field office expense, and all other elements of cost and expense not embraced within the "actual field cost" as hereindefined, save that where the Contractor's Camp or Field Office must be maintained primarily on account of such Extra Work; then the cost to maintain and operate the same shall be included in the "actual field cost." No claim for Extra Work of any kind will be allowed unless ordered in writing by the Engineer. In case any orders or instructions, either oral or written, appear to the Contractor Lo involve Extra Work for which he should receive compensation or an adjtstment in the construction time, he shall make written request to the Engineer for written order authorizing such Extra Work. Should a difference of opinion arise as to what does or does not constitute Extra Work, or a.+ to the payment therefor, and the Engineer insists upon its performance, the Contractor • 17 • shall proceed -ui*_a the work after making written request for written order and shall keep nn accurate account of the "actual field cost" thereof, as provided ;nder Method C. The Contractor will thereby preserve the right to submit the matter of payment to arbitration, as hereinbelow provided. 6.02 TIME OF FILING CLAIMS: It is further agreed by both parties hereto that all questions of dispute or adjustment presented by the Contractor shall be in writing and filed with the Engineer within thirty (30) days after the Engineer has given any directions, order or instruction to which the Contractor desires to take exception. The Engineer shall, within a reasonable time, reply to such written exceptiaas by the Contractor and render his final decision in writing. In case the Contractor should appeal from the Engineer's decision, a demand for arbitration shall be filed with the Engineer and the Owner in writing within ten (10) days after the date of delivery to Contractor of the Engineer's final decision. It is further agreed that final acceptance of the work by the Owner and the acceptance by the Contractor of the final payment shall be a bar to any claims by either party, except where noted otherwise in the Contract Documents. • 6.03 ARBITRATION: All questions of dispute under this Agreement shall be submitted to arbitration at the request of either party to the dispute. The parties may agree upon one arbiter; otherwise, there shall be three, one named in writing by each party and the third chosed by the two arbiters so selected; or if the arbiters fail to select a third within ten (10) days, he shall be chosen by a District Judge serving the County in which the major portion of the project is located, unless otherwise specified. Should the party demanding arbitration fail to name an arbiter within ten (10) days, the Engineer shall appoint such arbiter. Should either party refuse or neglect to supply the arbiters with any papers or informa- tion demanded in writing, the arbiters are empowered by both parties to take ex parte proceedings. The arbiters shall act with promptness. The decision of any two shall be binding on both parties to the contract. The decision of the arbiters upon any question submitted to arbitration under this contract shall be a condition precedent to any right of legal action. The decision of the arbiter or arbiters may be filed in court to carry it into effect. The arbiter, if they deem the case demands it, are authorized to award the party whose contention is sustained, such sums as they deem proper for the time, expense and trouble incident to the appeal, and if the appeal was taken without reasonable cause, they may award damages for delay occasioned thereby. The arbiters 18 shall fix their own compensation, unless otherwise provided by agreement, and shall assess the cost and charges of the arbitration upon either or both parties. The award of the arbiters must be made in v riting. 7. ABANDONMENT OF CONTRACT 7.01 ABANDONMENT BY CONTRACTOR: In case the Contractor should abandon ind fail or refuse to resume work within ten (10) days after wrLtten notification from the Owner, or the Engineer, or if the Contractor fails to comply with the orders of the Engineer when such orders are consistent with the Contract Documents, then, and in that case, where performance and payment bonds exist, the Surety cn the bonds shall be notified in writing and directed to complete the work, and a copy of said notice shall be delivered to the Contractor. After r=ceiving said notice of abandonment, the Contractor shall not remove from the work any machinery, equipment, tools, materials, or supplies then on the job, but the same, together with any materitls and equipment under contract for the work, may be held • for usia on the work by the Owner or the surety on the performance and payment bonds, or another contractor in completion of the work; and the Contractor shall not receive any rental or credit therefor (except when used in connection with Extra Work, where credit shall be allowed as provided for under Section 6, Extra Work and Claims), it be-Lng understood that the use of such equipment and materials will ultimately reduce the cost to complete the work an6 be reflected in the final settlement. When: there is no performance bond provided or in case the Surety should fail to commence ccmpliance with the notice for completion hercinbafore. within ten (10) days after service of such notice, then the owner may provide for completion of the work in either of the following elective manners: 7.011 The Amer may thereupon employ such force of men and use such machinery, equipment, tools, materials, and supplies as stid owner may deem necessary to complete the work and charge the ecpente of such labor, machinery, equipment,tools, materials, and supplies to said Contractor, and expense so charged shall be (4educted and paid by the Owner out of such moneys as may thereafter At any time become due to the Contractor under and by virtue of this Agreement. In case such expense is less than the sus which would have been payable under this contract if the same had bean completed by the Contractor, then said Contractor shall receive the difference. 1~ 19 In case such expense is greater than the sum which would have been payable under this contract if the same had been completed by said Contractor, then the Contractor and/or his Surety shall pay the amou:.t of such excess to the Owner; or 7.012 The Owner, under sealed bids, after five (5) days notice published one or more times in a newspaper having general circulation in the county of the location of the work, may let the contract for the completion of the work under substantially the same terms and conditions which are provided in this contract. In case of any increase in cost to the Owner under the new contract as compared to what would have been the cost under this contract, such increases shall be charged to the Contractor and the Surety shall be and remain bound therefor. However, should the cost to complete any such new contract prove to be less than what would have been the cost to complete under this contract, the Contractor and/or his Surety shall be redited with the difference. When the work shall have been substantially completed, the Contractor and his Surety shall be so notified and Certificates of Completion and Acceptance, as provided in Paragraph 5.06 hereinabove, shall be issued. A complete itemized statement of the contract amounts, • certified by the Engineer as being correct, shall then be prepared and delivered to the Contractor and his Surety, whereupon the Contractor and/or his Surety must pay any amount due the Owner, as indicated by said statement, within fifteen (15) days after the date of such Certificate of Completion. In the event the statement of accounts shows that the cost to complete the work ie less than that which would have been the cost to the owner had the work been completed by the Contracter under the terms of this Contract, then all machinery, equipment, tools, materials, or supplies left on the site of work shall be turned over to the Contractor and/or his Surety. Should the cost to complete the work exceed the contract price, and the Contractor and/or his Surety fail to pay the amount due to the Owner within the time designated hereinabove, and there remains any machinery, equipment, tools, materials, or supplies on the site of work, notice thereof, together with an itemized list of such equipment and materials shall be mailed to the Contractor as designated in this contract; provided, however, that actual written notice given in any manner will satisfy this ecndition. After mailing, or other giving of such notice, such property shall be held at the risk of the Contractor and his Surety subject only to the duty of the Owner to exercise ordinary care to protect such property. After fiftcza (15) days from the date of i 20 • said notice the Owner may sell such machinery, equipment, tools, materials, or supplies and apply the net sum derived from such Pdle to the credit of the Contractor and his Surety. Such sale may be made at either public or private sales, with or without notice, as the Owner may elect. The Owner shall release any machinery, equipment, tools, materials, or supplies, which reme3n on the work and belong to persons other than the Contractor or his Surety, to their proper owners. The books on all operations here- in shall be open to the Contractor and his Surety. 7.02 ABANDONMENT BY OWNER: In case the Owner shall fail to comply with the terms of this Contract, and should fail or refuse to comply with said terms within ten (10) days after written notification by the Contractor, then the Contractor may suspend or wholly abandon the work, and may remove therefrom all machinery, tools, and equipment, and all materials on the site of work that have not bees inc!.:ted in payments to the Contractor and have not been wrought :sto the work. And thereupon, the Engineer shall make an estimate of the total amount earned by the Contractor, which estimate shall include the value of all work actually completed by said Contractor (at the prices stated in the attached proposal where unit prices • are used), the value of all partially completed work at a fair and equitable price, and the amount of all Extrd Work performed at the prices agreed upon, or provided for by the terms of this contract, and a rt:asonable sum to cover the cost of any provisions made by the Contractor to carry the whole work to completion and which can be utilized. The Engineer shall then make a f:aal statement of the balance due to the Contractor by deducting from the above estimate all previous payments by the Owner and all other sums that may be retained by the Owner under the terms of this Agree- ment, and shall certify same to the Owner, who shall pay to the Contractor, on or before thirty (30) days after the date of the notification by the Contractor, the balance shown by said final statement as due the Contractor under the terms of this Agreement. • 21 i CITY OF DENTON, TEXAS STREET IMPROVCHBT PROGRAM NO. 6 ALTEPJWrE, "A" DETAIL SPECIFICATIONS SECTION 100 - GENERAL 100.1 MATERIALS: These specifications are intended to be so written that only new materials of the btst quality and grade will be furnished. The fact that the specifications may fail to be sufficiently complete in some detail will not relieve thq Contractor of full responsibility for providing new materials of high quality and protecting them adequately until incor- porated in the project. The specifications for materials set out the ninimum standard of quality which the Owner believes necessary to obtain a satisfactory project. No substitutions will be permitted until the Contractor has received written permission from the Engineer to make a sub - atitution for the materials which have been specified. 100.2 WOP"AlIS)U P: 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 project. The specifications are intended to be go written that only first class workmanship and finish of the best grade and quality *Ill result. The fact that these specifications may fail to be so complete as to cover all details will not relieve the Contractor of full responsibility for pruviding a completed project of high quality, first class finish and appearance and satisfactory for operation, all within the intent of the plans and specifications. . 100.3 DTF110SAL 0E' DTSATTROVt'u t1A1JR1A1, AND 1%10111'XANPT0?: Materials or workmanship which arc installed and later found damaged or not acceptable shall be removed end replaced ..ith acceptable material and workmanship. Inspection before installation shall not relieve the Contractor from the responsil)iliLy to furnish good quality materials and workmanship. Upon specific instructions from the Engineer, the Contractor shall ituned lately remece from the site any materials or workmanship found to be dam~.ged or in any way i~liling to meet the specifications. Only damaged material or workmanship which may be accepted by the Engineer after repairing will be allo,,.,ed to remain on the site. 100-1 SECTION 101 - ROADWAY EXCAVATION AND DIBAMCtENT 101.1 EXCAVATION: The work to be performed under thi% specification will consist of required excavation within the limits of the roadway which is necessary for the preparation and construction of the road-bed, embankment, subgrade, shoulders, trenches for combined curbs and getters, alley and cross street approaches, driveways, sidewalks, etc., all in conformity with the lines, grades, and dimensions shown on the plans. Excavation shall also include the removal and satisfactory disposal of all trees, shrubs, brush, stumps, posts, weeds, rock, existing pavement, gravel, debris, sidewalks, concrete steps, driveways, valley gutters, stona sewers, drain culverts, abandoned water, sewer and gas lines, and alI other materials except where the removal of existing structures or materials is specific- ally classified separately in the proposal and contract documents as separate pay items. Excavation shall also include the stripping and removing of top soil, the removal of all unsuitable materials encountered, the replacement of unsuitable materials with satisfactory materials, the doing of all necessary ~ backfilling, the restoring of all streets, alleys, right-of-.way, public and private property occupied or damaged by the Contractor in the perfor- mance of the work. Excavation shall be performed by machines of a type and capacity adapted to the performance of the work to be done. • The Contractor shall make all necessary arrangements to locate and obtain sites, subject to the approval of the Engineer, for the disposal of all surplus materials not to be ir,corporated in the completed work. Excavated areas shall be cut to the elevations, grades and slopes indicated on the drawings. Upon completion of the work, surfaces of excavated areas shall be uniform and free draining w..hout depressions causing pocketing of surface water or humps proiucing localized runoff and gullying. During construction, excavation shall be performed in such a manner and sequence as to provide proper drainage at all times. 101.2 CONSTRUCTION MMODS_ After the site of the work has been properly cleared, the excavation and grading may proceed in conformity with the plans and these specifications and as directed by the, Engineer. Rock, detached Ioulders, existing structures which are abandoned, and all other obstructions, shall be removed to a depth of not less than one foot below the subgrade elevation. Rock excavation shall extend one-half foot below the required subgrade elevation for the entire mild bad width, from back of curb to back of curb, or as directed by the Engineer, and shall be backfilled with select materials as directed by the Engineer. When required by the plans and specifications or as directed by the Engineer, selected materials from the excavation shall be utilized to improve the { road-bed, in which case the ,pork shall be performed in such manner and • sequence that suitable materials may be selected, removed separately and deposited in the roadway within the limits and to the required elevations. 101-1 ! Soft, spongy or other unstable foundation material shall be removed to the depth directed by the Engineer, and shall be replaced by select materials and compacted as specified. Care shall be exercised so as not to disturb the natural ground below the required finished subgrade elevation except for construction of structures, or when so ordered by the Engineer, except when the plans specify the uniform scarifying below the subgrade elevation. Excavation outside the slab edge or the back of curb lines shill not be wider than necessary to properly construct the work. The finished grades, slopes and edges of the exca-lation on all cross streets, alleys and driveway approaches, parking, etc., shall be backfilled where necessary, using select materials thoroughly compacted and dressed off uniformly in a neat and workmanlike manner. Slab edges not protected by curbs shall be backfilled for a width of not less than two feet, measured at a level with top of slab. The Contractor shall at all times make ample provisions for completely and readily draining the subgrades and excavations. 101.3 PROTECTION OF TREES, SHKURBERY AND PLANTS: Where trees, plants, shrubbery, etc., are adjacent to the line of the work and which are not to be removed, the Contractor shall protect such trees, plants, shrubbery, etc., by substantial wooden boxes and guards, and shall not permit machinery or employees to scrape, tear the limbs from, or damage, or attach any guy cables to them. And if in the opinion of the Engineer such trees, plants, shrubbery, etc., would be damaged by the machinery, hand excavation may be required. The Contractor shill be responsible for all damages to adjacent trees, shrubbery, plants, etc. 101.4 DIBANDIFNT: EmbanKrmt:.:t .,r fills shall be constructed at the locations and to the lines and grades indicated on the drawings, or as e3tablished by the Engineer. Materials placed in fills shall be free from all vegetable matter, trash and frozen materials, and stones haying a maximum dimension greater than two inches. Fills shall be fo nned of excavated materials placed in successive layers of such widths and lengths as are suited to the sprinkling and compaction method utilized. Embankments shall be constructed in layers not exceeding six inches in thic]-,ness after compaction. The layers shall be compacted as specified in 101.5. The Contractor shall add moisture to or shall dry by aeration, each layer as may be necessary to meet the requirerents of this specification for compaction. The addition of moisture to or drying by aeration of, each layer, shall be accompanied with thorough mixing so as to bring aii material in each layer to a uniform moisture content. Cowpaction shall be accomplished with tamping rollers, discs and pneumatic rollers of approved design. Tamping rollers shall be used except for the final rollirng of the completed fill which shall be accomplishes by rubber-tired rollers. The roll.ets, unless otherwise directed, shall be oporated at a speed between two and three miles per hour. All soft areas that develop under construction operations shall be scarified, aerated or moistened as required, and compacted to the full depth required to obtain the specified density for each layer. Portions of embankments 101-2 • which are near adjacent walls, pavements or other fixed objects to permit use of the above specified rolling; equipment for compacting, and other portions which the roller cannot reach for any reason, shall be thoroughly compacted by tamping in two-inch ]Byers with mechanical tampers or other equipment as approved by the Engineer. The degree of compaction for such portions of the ecnhankmcnt shall be equivalent to that obtained by sprinkling and rolling as specified for other respective portions of the embankment. Any damage.to adjacent walls, pavements or other fixed objects shell be replaced or repaired at the expense of the Contractor. When fill or embankments are to be placed on ground having a slope greater than one vertical to four horizontal, the surface of such ground shall be plowed, stepped, or broken up, as directed in such manner that the fill material will bond with the existing, surfaces. Prepared surfaces shall be wetted and compacted where so directed. All slopes against which fill is to be placed and which are steeper than one vertical to one horizontal shall be excavated to not steeper than one vertical to onr horizontal slope prior to placement of fill.. 101.5 REQUIRED DENSITY OF FMBANKMENTS: Except where otherwise specified, the degree of compaction a-id density shall be determined and controlled in accordance with the requirements of A.A.S.H.O. Standard Method T-99-57 at approximately optimum moisture content. All embankments beneath pavements shall be scarified, mixed, reshaped by blsding, sprinkled and rolled to a density of not leas than 95 per cent of maximum density at approximately optimum motstcire as determined by the Standard A.A.S.11.0. density method. In cut sections the subgrade below the subbase or base course for pavement, scarified as specified in (c) above shall be compacted to 95 per cent of maximum density at approximately optimum moisture as determined by the Standard A.A.S.H.O. density method. All embankment outside of pavement areas, except the top 3/10 foot of the embankment shall be compacted to a density of not less than 90 per cent of maximum density at optimum moisture as determined by the Standard A.A.S.H.O. density method. The top 1/30 embankment shall receive four passes at the pneumatic roller with the material at its optimum voisture content. 101.6 MEASUREMENT AND PAYMENT: Measuremo nt of Roadway Excavation shall be made of the surface area of the completed excavation or embarn1:rient based on the product of the actual measured length and of the width dimension shorn on the plans. Payment will be made at the contract unit price per square yard as indicated in the Proposal under the Roadway Excavation pay item; such price shall be the total compensation for the furnishing of all labor, tools, materials, equipment, machinery, clearing and grubbing, disposal of surplus materials, embankment, backfill, and all other incidentals necessary to complete the excavation in accordance with the plans and specifications, 101-3 SECTION 102 - PREPARATION OF SOIL LIME SUA GRADE 102.1 GEM.:RAL: After completion of the Roadway Excavatlon and Embankment work to the grades shown on the plans and staked by the Fngineer, the existing soil in place shall be plowed, scarified, mizrd with a hydrated Base slurry and compacted to 95 per cent of maximum dcri,;ity at optimua moisture content in accordance with A.A.S.11.O.Standard 7-99-57 in order to provide a mItilium six-inch (6 inch) depth of hydrated lime stabilized soil subgrade.

Gon-urrence on the part of the Engineer in any propose.] construction 111fthode, approval of equipment, or approval of forms shall not be c,msider.d as relieving ti 2 Contractor of the responsibility for the htifety or correctness of hi: methods and adequacy of this equipment safety or from carrying out the work in full accordan-:c with contract. 145.6 FOR?S: F'orris shall be of wood or steel construction and small 1,, built mortar-tight and of material sufficient in strength to prevent hntyiag between supports and shall be set and maintained to the lines designated until the concrete. is sufficiently hardened to permit form AImoval. During the elapsed time between the buildi1~g of the forms and the placing of the conrrc•te, thv forms shall be mal,itairked in a manner to prevent warning and shrinking. All details of font construction shall L„ subject to the approval of the Yngfneer, aiul the permission to place concrete will not be given until ail of such work is ,orplete to hie, hritisfaction. 1puttiber for forms shall be properly seasoned and of good quality. It Mull he frcc+ from loose or unsound knots, knot holes, twists, shaker., d ca; :end other imperfections t,hich would affect its strength or impair the finished surface of the concrete. The lumber used for facing or blienting shall be surfaced on at least one side and two edges and shall l-v sized to uini.fornn thickness. Forms shall be suitably anchored and • ,Igidly braced to prevent move:igoiit while placing concrete. 105-3 y Metal form ties of an approved type shall be used to held forms to place. Such ties shall be of type especially designed for use in connection with concrete work, and they shall have provisions to pennft ease of removal of the metal as hereinafter specified. The use of wire form ties will not be permitted except for minor special form areas when the use of rigid type metal ties would be impracticable. The use of metal form ties of type that are encased in paper or other materials to allow the removal of the complete tie, ]caving a hole through the concrete structure, will not be permitted in the construction of water bearing walls. Metal ties shall be held in place by devices attached to walls. Each device shall be capable of developing the strength of the tie. Pipe spreaders will not be permitted. All metal appliances, used inside of forms to hold them in correct Align- ment shall be removed to a depth of at least one-half inch from the surface of the concrete and shall be so constructed that the metal may be removed without undue injury to the surface by chipping or spelling. Such devices when removed, shall leave a smooth opening in the concrete surface. Burning off of rods, bolts, or ties will not be permitted. Where wire ties are used, all wires upon removal of the forms shall be cut back at least one-half OD inch from the face of the concrete with a sharp chisel or nippers. All cavities produced by the removal of metal tics shall be carefully cleaned and completely filled with re-tempered sand cement mort,rir mix in proportion of one to three, and the concrete shall be left smooth and even.

Unless authorized by the Engineer, no concrete shall be placed in any unit prior to the completion of the forrriork and the placement of the reinforcement. Whenever it is necessary to continue the trixing, 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 cperations to be completed in daylight hours. The sequence of placing concrete shall be as provided oil the Plans or in • the Specifications. 'ihe operation of depositing and compacting the concrete 305-4 • shall be conducted so as to form a compact, dense, impervious mass of uniforms texture which shall show smooth faces on all surfaces. The placing shall be so regulated that the pressures caused by the plastic concrete shall not exceed the loads used in the design of forms. 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. Concrete shall not have a free fall of more than eight (8) feet. The spattering of forms or reinforcement bars shall be prevented if the concrete so spattered will dry or harden before being incorporated in the mass. Concrete shall be placed in continuous horizontal layers approximately 12 inches in thickness. Not more than one hour shall elapse between the placing of successive layers of concrete in any portion of the structure included in a continuous placement. Each part of the forms shall be filled by depositing concrete directly as near its final position as possible. The coarse aggregate shall be worked back from the face and concrete forced under and around the reinforcing bars and pipe or other +_nserts without displacing them. Depositing large quantities at one point in the forms and running or working it along the forms will not be allowed. Laitance or foreign matter of any kind shall not be permitted to accumulate inside the forms; and openings in forms necessary for removal of same shall be provided. All concrete shall be well compacted and the mortar flushed to the surface of the forms by continuous working with concrete spading implements and mechanical vibrators of an approved type. Vibrators of the type which operate by attachment to forms or reinforcements will not be permitted. The vibrators shall be applied to the conrrete innnediately after deposit and shall be moved throughout the mass, thoroughly working the concrete around the reinforcement, embedded fixtures, and into the corners and angles of the forms until it has been reduced to a plastic wu,s. The mechanical vibrator shall not be operated so that it will peoc Irate or disturb layers placed previously which have become partially svt or hardened. The vibrator shall be of sufficient duration to accomplish thorough compaction anal complete embedment of reinforcement znd fixtures but shall not be done to an extent that will cause segregation. Vibration shall be supplemented by hand spading if necessary to insure the flushing, of mortar to the surface of all forms. Before the start of placing of concrete, all pipes, conduits, manhole casting, etc., required to be sot in the concrete, shall be pl.ced into position and firmly anchored. 105.8 FREEZING 1dIMII ER: k'hen depositing concrete at or near freezing • temperatures, the concrete shall havo. a temperature of at least 50 deorecs F., but not more than 120 degrees F. 7hc concrete shall be maintained at a 105-5 • t;+ture of at least 50 degrees F. for not less than 72 hours after I'll+' Illy,, or until the concrete has tfr.)roughly hardened. when necessary, i'id+rrule materials shall 'le hentcd before mixin an(' heating apparatus 61111) as stoves, salaciandcrs, etc., shall be supplied to mniutain the con rete at the requtrcd temperature. The Contractor -.hall be responsible for the protectic+r of concrete placed under any and all weather conditions. 105.9 CONS7.RUCH ON J0 P,T5: 'the joint formed by placing p4stic concrete in direct contact with concrete that has attained it Initial set shall be deemed a construction joint. Mien concrete in a structure or a portion of a structure is specified to be placed monolithic, the term monolithic shall be interpreted to mean that the manner and sequence of concrete placing shall be such that corstruction joints will not occur. Additional joints shall not be pr3v1ded without, written authoriza- tion from the Engineer. Any addition;il consrruction ,joints shall have details ey.ivalent to those shown on the plans for juint5 in similar locations.

Wood forms shall be rurnished in sections approximately five feet in length and shall be provided with adequate devices for secure settling so that when in place they will withstand, without springing, weaving or settling the impact and vibration of the finishing machine. (3) Subgrade Surface - The subgrade surface shell be tested os to crown, elevation, and density in advance of setting forms. The finished . surface when compacted to the desired density shall. be within plus or minus 0.03 of the grade line or elevation shown on the dra4ingn. The subgrade shall be completed to the plane of the typical sections shown on the drawings and the lines and grades established by the drawings or as directed by the Engineer. Any discrepancies shall be corrected in accordance with the requirements for subgrade course construction as specified. The surface shall be tested with an approved template, operated and maintained by the Contractor. The subgrade surface shall be maintained in a smooth, compacted condition, in conformity with the required section and established grade until the concrete. is in place. The subgrade course shall be wetted down sufficiently in advance of the placing of the concrete to insure its being in a firm and moist condition. In cold weather the subgrade shall be so treated, protected, and prepared as to produce a satisfactory surface entirely free from frost when the i concrete is deposited. (4) Form_Settl!T - Aft. the subgrade has been prepared as described above, the forms shall be set. The base under the forms shall be firm and cut true to grade's so'that each form section when placed will be firmly in contact for its entire lenf;th and base width. The form shall be staked into position so that its top, when tested by a 10-foot straight- edEe shall conform to the requirements specified for the surface of the concrete and the longitudinal axis of the upstanding leg shall not vary more than 1/4 inch. Form sections shall be tightly locked together. The alignment of paving lanes and returns will be set by the Engineer. All grade elevations for forms and placement of concrete shall be set by the Engineer. Forms shall be set for at least 500 feet in advance of concrete • placement. 117-3 • (S) Form kem_oval - Forms shall remain in place. at least 12 hours after the concrete has been placed against t'zem, or a longer prriod if so directed by the Engineer. Crow bars or heavy tools shall not be used against green concrete in removing the forms. Forms shall be well cleaned before re-oiling and re-use. 117.5 MIXING AND PLACING: (a) Concrete Mixers - Mixers shall be paving mixer,; of an approved desil;n. The mixers shall have a rated capacity of at lea :t cubic fect of mixed concrete, and shall not be charged in excess of 20 per, cent of the manufacturer's rated capacity. Mixers shall be capable of coobining the materials into a uniform mixture and of discharging this mixture without segregation. Stationary and paving mixers shall be provided with an acceptab_- device to lock the discharge mechanism until the required nixing time has elapsed. The mixers shall be operated at the drum speed designated by the manufacturer on the name plate. The mixing ocriods specified herein are predicated on proper control of the spec' of rotation of the mixer drum, and on proper introduction of the materials Into the mixer. The mixing, time will be increased when such increase is necessary to secure the required uniformity and consistency of the concrete, or when test samples eZ concrete taken ftom the front, center and back of the miner show a difference of more than 10 per cent in sand-cement or water-cement ratio. The mixers shall be maintained in satisfactory operating condition, and mixer drums :.hall be kept free of hardened concrete. Mixer blades shall be replszed when worn down • more than 10 per cent of their depth. Should any mixer at any time p-oduce unsatisfactory results, its use shall be promptly discontinuec' until it is repaired or replaced. Paving mixers shall be used at the rite of the work for mixing concrete far pavements, except as otherwise approved in writing by the Engineer. Paving mixers shall be equipped with boom rind bottom-dump bucket to handle the concrete from the mixer to the form. The bucket shall be of adequate size to handle the complete batch of concrete mixed, and the boom shall be of sufficient length to permit discharge of the concrete into its final position in the form. Paving mixers may be either single-drvn or dual-drum type. Dual-drum paving mixers shall be properly synchronized and the mixing time shall be determined by excluding the time requirr:d to transfer the concrete from the first to the second drum. The miring time for mixing each batch, after all materials are in the mixer, shall not be less than one minute. j The fixer, operating at a uniform Ispeed, shall revolve: a minimum. of 32 reva.utions after al: materials have been placed therein, Vefther the speed nor the volume capacity of the mixer shall exceed those reccmnended by the manufacturer. Excessive over-mixing, requiring additions o'_ water to preserve the required consistency, will not be permitted. Concrete not in place within forty-five minutes from the time the ingredients are ci,arged Into the mixing drum, or that has developed its Initial set, shall not be used. Vehiclca used in transporting materials from the batching plant to the mixers shall have bodies or compartments of adequiice capacf.ty to carry the materials • 117-4 • and to deliver each batch, separate and intact, to the mixer. Except as otherwise approved by the Engineer, loose cement shall be transported from the batching plant to the mixers in separate boxes or compartments which shall be equipped with wind-proof and rain-proof covers. (b) Placing - Concrete shall be deposited in such manner as to require the minimum of handling and shall be distributed so that when consolidated and finished, the slab thickness and surface grade required by the drawings will be obtained at all points. The placing of concrete shall be rapid and continuous between transverse joints. Placing will not be permitted when, in the opinion of the Engineer, the sun, heat, wind, or humidity prevents proper placement, consolidation, and finishing. Workmen shall not be permitted to walk in the concrete during placing and finishing operations with any earth or foreign material on shoes or bouts. Necessary hand spreading shall be done with shovels. not with rekes. The concrete adjacent to forms and joints regardless of slab thickness shall be consoli- dated with the aid of mechanical vibrating equipment approved by the Engineer. The spreading and striking-off of the concrete shall conform to the depth ar.1 cross section shown on the drawings and shall be perfo.med at such elevation slightly above grade that when properly consolidated, the surface of the layer w M be at the elevation indicated by the drawings and shall be free from porous areas and honeycombs. (c) Cold Weather Placia& - Concrete shall not be placed when the ambient temperature is below Y5 degrees F. nor when the concrc*e without special protection is likely to be subjected to fie^zing temporatures before final set has occurred. The temperature of the concrete when placed in the pavement shall be not less than 40 degrees F. nor more. than 60 degrees F. Heating of the mixing water and/or aggregates wail not be permitted until the temperature of the concrete has decreased to 45 degrees F. Heated materialb shr.11 be free from ice, snow, and frozen lumps tefore entering the mixer. Methods and equipment for heating shall be subiect to approval. Suitable means shall also be provided for maintaining the concrete at a temperature of at least 40 degrees F. for not less than 72 hours After placing. Salt, chemicals, or other foreign materials shall not he mixed with the concrete to prevent freezing. Any concrete damaged by freezing shall be removed and replaced at the expense of the Contractor. 117.6 FIELD TEST SPECRIE.NS: Samples of concrete will be taken in the field from mfrtures_nti- el n tfie pavernerst to determine the adequacy of control. of materials and the proportioning, consistency, mixing, and air content of the concrete. Test beams will also be required by determining conformance with the strength requirements of these specifications, and when so directed by the Engineer, for determin{ng the tine at which such pavement may be placed in service. Test beams will be molded and cured in conformity wJth T.H.D. Bulletin C-11. The Contractor shall furnish materials, labor, and facilities required for molding, curing, and protecting test borms at the site, The Contractor shall deliver the test beam.; to the laboratory and shall furnish • protection to the boom:; enroute•. Testing and breaking test berim- will be perforriod by the testing laborr,tury at the expense of the Engineer. 117-5 • (a) Specimens for Strength Tests - At the start of paving operations, flexural test beams in groups of two shall be made each day at intervals designated by the Engineer but not oftener than one test group for each 40 cubic yards of concrete placed. Beams in any test group shall be molded from the same batch of concrete. Making of these groups of test beams shall be continued until sufficient time has elapsed to make available a series of acceptable test beams having a minimum age of 14 daye for deter- mining conformance with the strength requirements of these speci:'cations. The above procedure will be applicable to revised mix proportions due to a change in the source of aggregates or a change in the water-cement ratio. After it has been estnilished that the mix proportions of tha concrete being placed comply with the durability and strength requirements, a test group of beams will be taken from every subsequent 300 cubic yards or less of concrete placed each day. (b) Specimc_ns_for Determining Time of 0~eniny, Pavement - A test group of at least two beams will be taken from the concrete placed in designated areas as specified by the Engineer. The beams of a test group will be made from fresh concrete removed from the same general area. 117.7 SPREADING AND FINISHING: (a) Sequence of Operations - Itanediately after placement, concrete shall be properly fir.1shed. The sequence of operations shall be as follows: • transverse machine finishing, longitudinal machine floating, straightedge finishing, fine burlap drag finishing and finally the edging of joints. The machine method of finishing shall be employed except that on odd widths or shapes of slab, hand methods will be permitted. Finishing equipment and tools shall be maintained clean, free from hardened concrete or grout, and in a condition satisfactory to the Engineer. A mechanically vibrated screed shall not be used. (b) Machine FinisbinR - (1) Equipment - The tram verse a,id longitudinal finishing machines shall be power-driven, shall be designed and operated to strike off, screed, and consolie-,ke the concrete, and rhall be of ample weight and power to produce proper finishing and withstand the roughest treatment anticipated under job conditions. The transverse finishing machine shall be provided with tw.) screeds readily and accurately adjustable for changes In pavement crown and compensation for wear and other causes. The longi- tudinal finishing machine shall be 7rovided with a longitudinal float not less than 1.0 feet in length, readily adjustable to a tiue dlauc. Any machine which causes displacement of the side forms that have been properly installed, or which causes frequent delays as a result of mechanical fail- ure, shall be replaced if so directed. When the finishing wachines ride the edge of a previously constructed slab, they shall be provided with ruhber- tired wheels. Othcr types of finishing equipment may be used on a trial basis upon submission of evidence to the Engineer of their successful per- formance in placing and finishing concrete of the quality and consistency required by these specifications. Failure of equipment permitted on tri:a to perform in a satisfactory manner, either mechanically .1i in ability to place and finish concrete in conformity with requirements of these spclci- fications, shall be cause for its rctnoval from the job site. 117-6 (2) Transverse Finlshinp, - Concrete, as soar as placed, shall b^_ accurately struck-off and screeded to the crown and cross-section shown on the drawings and to such elevation slightly abro..~ grade that when properly consolidated and finished, the surface of the pavement will be free from porous places and at the grade indicated the drawings or as directed by the Engineer. The finishing inachine ;~irrll make at least two trips over each area of pavement and as many more :,nd at such intervals as necessary to properly compact the concrete and prod,ire a suriaee of uniform texture, true to line and grade. Excessive tu;r,nipulation will not be p•,~rmitted. (3) hongitudinal Floating - After completion of finishing with the transverse finishing machine, the longitudinal mechanical float shall be operated to smooth and finish the pavement to grade. The float shall be operated parallel to the center line of the pavement with a short, quick motion, and shall travel slowly across the pavement, main- taining contact with the surface at all times. If contact with the sur- face is not made at all points, additional concrete as required shall be placed and screeded, and the float operated over the same area until a satisfactory surface is produced. In advancing the float, each new position shall lap the previous position by not less than one quarter of the float length. (c) Hand Fi_nishigS - Hand finishing shall be resorted to only • in those conditions pruvided for above, except as otherwise permitted and authorized by the Engineer. (1) rguip_v+ent - In approved steel-shod, hand-strike Lem- plate, unapproved steel-shod, tamping template, and a longitudinal float shall be provided for hand finishing. The templates shall. Le at least one foot longer than the pavement width, shall be equipped with handles, and the steel-shod edges shall be at least four inches wide. 'file longi- tudinal float shall be 10 to 16 feet in length, and in cross section shall be an inverted T, madeof a two-inch by six-inch or wider stc~l-shod plank for the base F,nd a two-inch by eight-inch plank for the verticnl leg. The float shall be rigid and substantially braced, providing means for main- taining a plane surface on the bottom of the base, and provided with suitable handles to assure smooth anal effective manipulation from foot bridges. The bottom edges of the base of the float shall be rounded on a radius not exceeding 3/8 inch. Floats made of metal or a combination of wood and metal may be used provided they confo nn to the requiroments for wood floats. (2) Finishing and b_loatin~ - Concrete, as soon an placed, shall be struck off and screeded to the crown and cross section and to such elevation above grade that, when consolidated and finished, the 117-7 surface of the pavement ehall b at the grade ect by the F'ngincer. The entire surface shall be tamped and the trmping operation continuc-d until the required compaction and reduction of internal and slirf.nce voids are secured. Immediately following Lite final tamping; of the snrfzce, the paveii.ent shall be floated longitudinally by hand from bridges resting on the side forms and spanning but not touching the concrete. If contact with the pavement is not mn.3e at all points by the float, additional con- crete shall be placed as required and screeded, and the float operated until a satisfactory surface has been produced. After a section has been smoothed so that the float maintains contact with the surface o the con- crete at all points, the bridges may be moved forward half the length of the float and the operation repeated over the new anu pre+viously floated surfaces. (d) Strailhtedl;ing - After the longitudinal floating is com- plete, minor irregularities and score marks remaining in tlic pavement surface shall be eliminated by removing or shifting surplus material, or by adding and working in freshly mixed concrete, if necescnary, by means of long handled floats and straightedges. The long-handled floats may be used to smooth and fill 'n open-CExturt!d areas in the pavement surfaces, but the final finish shrill be made cith the straightedges. Straightedges shall be 10 feet in length and may be operated from brldges or from the . side of the pavement. A straightedge rIpcrated from the r;ldr' of the pave-- I meat shall be cquippnd with a handle 3 feet lcog;er than ova-half the width of the pavctient. The straightedge shall oc placed at thf: center of the slab with the blade parallel to the center line and pullrd unif)rmly to the edge. The straightedge shall be advanced along the pavement in successive stages not more than one-half its length. Depressions shall be immediately filled with freshly mixed concrete, etruck off, consolidated, and refinished. Projections above the required elevation shall also be struck off and refinished. The floating and straightedging shall be done while the concrete is still plastic and workable and in such time sequence as to insure the removal of all water and laitance'from the surface. The straightedge testing and refloating shall continue until the entire sur- face is free from observable departure from the straightedge, conforms to the required grade and contour, and, when the concrete is hardened, will conform with the surface requirvm~nts specified under the parrigraph "Surface Test". Straightedges shall be constructed of aluminum or other approved light weigl.t metal and shall have. blades of box or box girder cross-section construction •-ith flat bottom, adequately reinforced to insure rigidity and accuracy, and suitable handles for operation oil the pavement. (e) 1`ra,&&i~& - When most of the water glaze or sheen has disappeared and before the concrete becomes non--plastic, the surface of the pavement shall be dragged longitudinally with burlap. the burlap drag shall consist of four folds or layers of burlr.n approxa+riately 3 feet in length longitudinally and extending transversely the full width of the paving lade. 117-B The lea3ing transverse edge of the drag shall be securely attached to a traveling, bridge, leavlnE; at least one foot of the burlai+ adjacent to the folds of burlap or by oilier means approved by the Fngineer. The drag shall be operated with the burlap moist and shall be cleaned or changed as necessary wh,!u the burlap becomes sufficiently coated with lattance to prevent the production of a finished surface hnving a uniformly fine granular or sandy texture. The dragging shall be carefully done so as not to leave disfiguring marts upon the surface. The edges of the pavement shall he dragged as necessary with a small hand-operated burlap drag following rdpe tooling. (f) Ed&tn.a. After dragging has been completed, but before concrete has attained initial set, edger, of slabs along forms and at joints, wliere indicaLed by the drawings or otherwise required by the Engineer, shall be carefully finished with an edging tool to form a smooth rounded surface of the required radius. Corners or edges of slabs which have crumbled and any areas which lack sufficient mortar for proper finishing shall he cleaned by removing loose fragments and soupy mortar, and shall be solidly filled and finished with a mixture of correct propor- tions and appropriate consistency. Unnecessary tool marks shall be elimi- nated and edges shall he smooth and true to line. After removal of forms, any damaged or honeycombed areas shall he filled witb mortar cr,mposed of one part cement to t•ao parts sand. • 117.8 CURING: Concrete shall be cured by protecting it against loss of moisture, rapid temperature change, and from rain, flowing gate.-, and mechanical injury for a period of not less than. 7 days from ilie beginning of the curing operation. Immediately after finishing operations have been r,mpleted, the entire surface of the newly laid concrete shall be ccvercd by the curing medium or combination of c:;ring mediums wbIch arc applicable to local conditions and approved by the Fngineer. The side of concrete slabs exposed by the removal of forms shall be protected ir;medistely to provide these surfaces with continuous curing treatment equal to the method selected for curing the slab surface and to prevent Injury to pavement edges ,end the underlying subgrade. The use of a covering, material which contain:: or becomes contaminated with sugar in any form, tannic acid, or any oche: substances considered detrimental to portl„nd cement will not be pernitttcd. The initial curing medium shall be effective and shall be applied so as to prevent, checking,, 6racking, and the appearance of dry spots in the surface of the concrete. 1he Contractor shall have the equipment needed for -idequste curing at hand and ready to install before actual concrete placc.iei^.t begins. In all cases in which the curing i.ivdium requires the use of water, the curing shall have prior r1ght to all water supply or supplies. Failure to provide sufficient cover material of the type selected, failure to maintain saturation In the moist-curing methods, lacy. of water to adequately core for both curing and other requirements, or other failures to comply with curing requirements sli<,11 be cause for inanediate suspension of ccncrotiug operations. 117-4 (a) Membrane CurinLs - fhe membrane curing compound F;hall be applied to the finished surfaces by approved power spraying equipment as soon as the free water has disappeared. Spraying prearcvre shall be sufficient to produce a fine spray and cover the surface thc,rouphly and completely with a uniform film. Spray equipment shall be maintained in first-class mechnnical condition and the spray nozzle Shall he provided with an adequate wind guard. The curing compound shall br applied in a 2-coat, continuous operation and at a coverage of not morn than 200 square feet per gallon for both coats. When application is made l,y hand-operated sprayers, the second coat s1,all be applied in a direction approximately at right angles to the direction of the first coat. The compound shall form a uniform, continuous, coherent film that shall not cheek, crack, or peel, and shall be free from pin holes or other imperfections. If discontinuities, pin holes or abrasion exist, an additional coat shall be applied within thirty minutes to the affected areas. Concrete surfaces width are subjected to heavy rainfall within three hours after the curing; compound has been applied shall be resprayed by the method and at the coverage <;pr•cified above. Any section covered by curing compound and damaged by subserlt+ent construction operations within the curing period shall be retreated. In the event hair checking; develops before the membrane curing compound can be applied, the concrete shall be moist-cured, as specified hereinbefore, for at least 12 hours before applying any membrane curing compound. Approved standby facilities for curing; concrete pavement shall be provided at a readily accessible location at the site of the work for use in event o rcechanical failure of the spraying equipment or any other conditions which may prevent correct application of the mend)rane curing compound at the proper time. Concrete surfaces to which membrane curing; compounds have been applied sh411 he kept free from foot and vehicular traffic and other sources of abrasion for a rd ninacca period of 7 days, except as required for sawing joints. 117.9 S11RFA_CI. TEST: After curing, has been completed, the surface of the pavement shall again be tested with a straightedge or device which shall be operated in such manner as to reveal any irrcg Oarities. Any portion of the pavement which shows A variation or departure greater than 1/E inch from the testing edge of a 10-foot straightedge shall be removed and replaced or corrected as directed by the Engineer. No area of p;ivcment rc-noved and replaced and no adjacent slab or portion of a slab which remains in the pavement abutting, the replacement slab shall have a length or width less than 10 feet. 117.10 GFADICONI'ROL: The finished concrete pavement surfaros shall be within plus or minus 0.04 fee, of the grades and elevations shown on the drai:ing,s, determined by the Engineer within five. days after rew oval of forms from pavecr,c-nt lanes in queFtion. Any portion of the pavement 411i0c exr(rd•; this amount shall be removed and replaced or corrected as r!:,rc~~rl by the Fnl;incer. No area of pavcrnen~ rorioved and replaced and no adjacent sl.b ')r portion of a slat, Oilch remains in the pavement abutting, the replacement slab shall hnvc lefwlL or width lcss than 10 feet. 1:7-10 • 117.11 PAVEMENT PROTECTION: The Contractor shall erect barricades to exclude public and construction traffic until the concrete is nt least seven (7) days old and has obtained a minimum average modulus of rupture of 500 pounds per square inch. The period of protection may be extended due to weather or other conditions as directed by the Engineer. At the end of seven (7) days th pavement may be opened to traffic as ordered by the Engineer and if so desired by the Contractor. Such opening, however, does not relieve the Contractor from his responsibility for the work. Where the Contractor desires to move any equipment not licensed for operation on public roads on or across any pavement opened to traffic, he shall protect the pavement from all damage by means of two-ply timber mats of 2" stock or runways of hea-.7ier material as approved by the Engineer. All pavement damaged by such equipment shall be removed and replaced at the Contractor's expense. 117.12 TOLERANCES IN PAVEMENT T11IChNESS: The pavement shall be of the thickness shown on the drawings. Any variations which may occur will be governed by the following; (a) Thickness Determination - The thickness of the slab will be determined by and at the expense of the Engineer on the basis of the aver- age of slab thickness measurements made on cores taken from it at such points • as the Engineer may select. Measurement of individual cores will be per.- formed in accordance with A.S.T.M. Specification C174. In calculating the average slab thickness, individual cores measuring in excess of the thick- ness shown oa the drawings shall be considered as the specified thickness, and individual cores measuring less than the specified thickness by 1/2- inch or more shall be considered part of a defective section and shall not be included in the average. The lengti, of any deficient section shall be the distance between the nearest cores of satisfactory thickness, and the width shall be the entire width of the paving lane from which the cores are taken. (b) Permissible Deviation - Where the average thickness of pave- ment, determined as provided abn-,, is within 1/4-inch of the thickness required by the typictl cross sectiol shown on the drawings, the pavement will be considered within the lir,.t of perziissible thickness variation and satis- factory in thickness. (c) Non rmis_si_b_lc _Deviati_on - Where the average thickness of pavement, determir^d as provided above, is less than the thickness shown on the drawings by wore than 1/4-inch but less than 112 inch, the pavement will be considered outside the limit of permissible thickness variation and be accepted and paid for only upon the basis of an adjusted unit price. The adjusted unit price to be used in payment for such pavement shall • 117-41 hear the same ratio to the concrete price as the square of the average thickness of the slab bears to the square of the thickness required by the drawing. (d) Deficiencies and Rt~~lncement. - If, in the opinion of the Pngineer, a deficiency in slab thickness of 112 inch or more is sufficient to seriously impair the service expected from the pavement, the deficient area shall be removed and replaced with a slab of quality and thickness satisfactory to the Engineer. The Engineer may allow the Contractor the choice of leaving the defective slab in place and receiv ng no com- pensation or payment for same, or of removing and replacing the pavement as provided above. (e) Recheck._ - If the Contractor believes that the cores and measurements taken are not. sufficient to indicate fairly the actual thick- ness of pavement, additional cores and measurements will be taken provided the Contractor will bear the extra cost of drilling and filling holes in the pavement. 11-7.13 JOINTS: Joints of the various types shall be placed and finished as shown on the drawings or as directed by the Engineer. Joints shall be perpendicular to the finished grade of the pavement, and when tested with a straightedge placed at right angles across the joint, thc• ;surfaces of adjacent slabs shall not vary from the straightedge by more than 1/8-inch. Transverse expansion and contraction joints shall be straight and continuous and shall extend from edge to edge of the pavement throuPiout Al paving lanes which are connoted in a single paved area. Dowels and tie bars shall be prepared and placed across joints where indicated by the drawings, correctly aligned and securely held in position during placing and finishing operations by the use of metal chairs or other installing devices approved by the Engineer. Dcwols shall be held securely in place parallel. to the surface and center line of the pavement. The method used in holding dowels in position shall develop such accur,.cy that the error in any dowel. in the entire indtallation from its required position after the pavement has been finished shall not be greater than angle whose l angent is 3/48. The Con- tractor shall furnish an approved template for checking the position of the dowels. Dowels shall be clean, straight, and smooth with ends free from burs. Thr portion of each dowel intended to move within the concrete or expansion coop shall be painted with one coat of red-lead cis blue-lead paint. When the paint has dried and before concrete is placed each dowel shall be wiped clean and coated with a thick even film of A neral lubricating grease, except the dowels in transverse construction joints occurring at locations other than regularly located transverse joints shall not be. painted or greased. 1.17-12 4 (a) Contraction Joirts. - Transverse and longitudinal contraction • jointH shall be'o t e wea ene3c pTane or dummy type formed by cutting a groove in the hardened concrete with a power driven saw. The joints shall be constructed to the dimensions and details shown on the drawings but in no case shall the depth be less than the maximum size aggregate used. The time of sawing shall be varied, depending on exinting and anticipated weather conditions, and shall be such as to prevent uncon- trolled cracking of the pavement. Removal of the affected pavement may be required by the Engineer where uncontrolled cracking occurs due to negligence by the Contractor. Sawing of the joints shall commence as soon nw the concrete has hardened sufficiently to permit rutting the con- crete without excessive chipping, spalling or tearing. Vic sawing operation shall be carried on both during the day and at night as required, regardless of the weather conditions. The joints shall be sawed at the required spacing consecutively in the sequence of the concrete placement, unless otherwise approved by the Engineer. A chalk line or other suitable guide shall be used to mark the alignment of the joint, and the saw cut shall be straight from edge to edge of the pavement. The surface of pavement cured with membrane: curing compound shall be wetted with water, in tho region of the s3w curt prior to sawing in order to protect the curing membrane from abrasion. Workmen and inspectors shall wear clean rubber soled footwear, and the number of persons walking on the pavement shall be limited to those actually performing the sawing operation. Immediately after sawing each joint, the saw cut and adjacent concrete surface shall be thoroughly flushed with water until all waste from sawing is removed from the joint. Any membrane cured surface damaged during the .;awing operations shall be resprayed as soon as the surface becomes dry. The sawing equipment shall be adequate in number of units and power to complete the sawing at the required rate. An ample supply of saw blades shall be available on the job before concrete placement is started, and at least one standby sawing unit in good working order shall be available at the job site at all times during the sawing operations. (b) Uncontrolled _Cracks. - It shall be the responsibility of the Contractor to diligently employ a12 provisions of these specifications to prevent the occurrence of uncontrolled cracks in the finished pavement. However, should uncontrolled cracks occur in the finished pavement through no negligence on the part of the Contractor, the cracks shall be enlarged, when so directed by the Engineer, by means of a power-driven too] or bit specifically designed for this purpose. The bit shall rotate about a vertical axis at sufficient speed to cut a smooth walled, slightly tapered groove in the concrete on the meandering linee of the crack. The machine used to power the cutter shall be so designed as to permit the cutter to follow the trace of the crack without deviation. The groove shall be routed to a depth of approximately 1 inch and a top width of not less than 112 inch nor more than 5/8-inch. The finished groove shall be cleaned and sealed in accordance with the specifications. Sand b]a,t cleaning of the cracks prior to sealing will be. accomplished when so directed. • ]17-13 MMMMI~ (c) Cocstructia11 Jointti - Longitudinal construction joints between paving lanCs shall be located as shown on the drx.lings. Dowels or keys shall be installed in the longitudinal constructloi, joints as required and in accordance with the details shown on the drawings. Metal keyway fo nas, securely fastened to the concrete forms, shrill be used for forming horizontal keyways. Transverse construction Joints shall be in- stalled at the end of ea,h clay's placing operations and at any other points within a paving lane when concrete placement is interrupted for 30 minutes or longer. They shaill be installed in the location of a planned transverse contraction or expansion joint. Transverse construction Joints shall be of the type as requ red by th_ drawings. All constructtnn joints shall be edged with a tool which will maize a groove of required width and 1/4-inch depth and later sawed to the depth shown on the drawings. Immediately otter sawing the groove shall be cleaned free of cutting debris. (d) Expansion Joints - Expansion joints shall be formed by miens of wood boards conforming with A.A.S.11.0. Designation ;190. Devices used for installing the joints shall be adequate to hold the parts of the joint in proper position and protect the filler from damage during toncreting operations and shall be removable without final detriment to the pavement. Adjacent sections of filler shall be fitted tightly together and held in line to insure continuity and to prevent any concrete from entering the extension space. Any concrete which has flowed into a gap between the expansion joint strip and the edge forms of the pavcnLent shall • be cut out immediately after the forms have been removed. Expansion joints shall be formed about structures and features which project through, into, or against the pavement using joint filler of the type, thickness, and width shoi;:n on the drawings or as directed by the Fngincor, installed in such manner as to form a co:aplete, uniform separation between the structure and pavement. (e) Scalin Joints Joints within the paved areas as indicated on the drawings shall be sealed with scaling umLe rial conforming to Federal Specifications SS - S - 164. (1) Time_ of As~rlication - The joints shall be scaled immediately following the curing period or as soon thereafter as weather conditions permit as directed by the Engineer. (2) 1.1mita_ttons - 11ie concrete at the joint shall be surface cry, and the atmospheric and pavement temperatures shall be no less than 50 degrees F. at the time of application of the sealing materials. The temperature requirements may be waived only when so directed in writing by the En„sneer. 117-14 • (3) C]cnuin& - Before filling, joints shall be cleaned of all extraneous matter adhering to the faces and bottom of the joints. Compressed air jets and such additional equipment as may be necessary to clean the openings and dry the contact faces of the joints shall be used. The faces and bottom of the saw cuts shall b•.: dry when filled with the scaling compound. (4) Markin - Unless otherwise specified, shipping containers Shall be marked with the name and type of the material, specifi-cations number, quantity contained therein, as defined by the contract or order under which the shipment is made, the pouring temperature recommended by the manufacturer, the name of the Contractor, the number of the contract or order, and the stock number. In addition, each shipping container shall be marked to indicate clearly the batch of which Lt forms a part. (5) Ferment - Care should be exercised to secure equip- ment for heating that is suitable for the purpose. The material should be heated in a kettle or tank construrted as a double boiler, with the space between the inner and outer shells filled with oil, asphalt, or other material for heat transfer and positive temperature control. Other methods of indi- rect heating satisfactory to the Engineer may be used. Direct heating should not be used. Control of the treatment of the material may be effected through flow tests made on specimens prepared from the material as applied • to the joint. (6) Yo_uri L Se_iling j,,terial_ - No joint sealer shall be installed until the joints to be sealed have been inspected and approved by the Engineer. The joints shall be completely filled flush with the pavement surface, without formation of voids or entrapped air, using pressure type equipment applicable to the type of material to be installed. Excess scaling material shall be removed from the pavement by approved methods and wasted. (f) .p2roval of Sealed _Joints - All joints shall be completely filled wi.;r sealing material, the sealer well bonded to the concrete, and free from voids and entrapped air. Any joints which do not meet those requirements as determined by the Fngineer shall be corrected by the Con- tractor by removing the sealing material and resealing the joints in a satisfactory manner. 117.14 MEASUREMENT: Portland cement concrete paverent of tee thickness specified will be measured by tho square yard of completed and accepted pavement, based on the width dimension being, the back to back of the curbs distance as indicated In the Plans. 117.15 PAYMENT: The yardage rcieasured as provided above will. be paid fui at the contract unit price bid per square yard for "Five-inch reinforced Concrete Pavement", and also for "Six-inch reinforced Concrete Pavement"; which price shall be full compensation for shaping and fine grading the subgr.^de, including 117-15 i applying all water required; for furnishing, loadinp,, unloading, storing, hauling, and handling all concrete ingrcdientn, including freight and royalty involved; for mixing, placing, curing and finishing all concrete; for furnishing and placing all joint mat(-rlals; reinforcing steel, tie bars, and joint sellers, for constructing rind scaling all joints; and for all labor, equipment tools and incidentals necessary to complete the work as specified herein. 1 S 117-16 it The above plans, spccificat'ons, bid, bid prope)!,al, and/or drawings are hereby r.pproved oy the contracting parties, and nre incorporated Into and made a part of the general contract agreement by and between the Contractor and the City of Denton, called Oti.,uer.
