Builders risk (where above-ground structures are involved). 3.174 AUTOMOBILE INSURANCE - BODILY INJURY AND PROPERTY DAMAGE: The Contractor shall procure and maintain, during the life of this contract, Automobile Insurance in an amount not less than $25,000 for injuries, including accidental death, to any one person and subject to the same limit for each person, an amount not less than $5(.,000 on account of one accident, and automobile property damage insurance in an amount not less than $5,000. 3.175 SCOPE OF INSURANCE AND SPECXAL HAZARD: The Insurance required under the above paragraphs shall provide adequate pro- tection f.or the Contractor and his .pub-.:gym tractors, respectively, against damage claims which may Prise from operations under this contract, whether such operations by the insured or by my one 11 directly or indirectly employed by him, Insuran,:c• also shall be provided against special hazards, if any, as may 1,v set forth in the Special @onditicns or Special Provisions, or el"cwhere in these Contract Documents. 3.176 PROOF OF CARRIAGE OF INSURANCE: The Contra(:Lor aha'l furnish the owner with satisfactory proof of coverage by insur- ance required in these Contract Documents in amounts and by carriers satisfactory to the Owner. Proof of carriage of insur- ance by sub-contractors shall be furnished. 4. PROSECUTION AND PROGRESS 4.01 TIME 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 economy of construction; provided, however, that the order and the time of prosecution shall be such that the work shall be substantially 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 direct the time and manner of constructing the work done under this contract, so that 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 proposed 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 pants. 4.02 EXTENSION OF TIME: Should the Contractor be delayed in the completion of the work by any act or neglect of the owner or Engineer, or of any employees of elther,or by other contractors employed by the Caner, or by changes ordered in the work, or by strikes, lockouts, fires, and unv.sual delays by common carriers, or unavoidable cause or causes beyond the Contractor's 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 Co;itractor shall give the Engineer prompt notice in writing of the cause of such delay. 4.03 HINDI'ANCES AND DELAYS: 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) 12 I 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 of this contract, and that for each day of delay beyond the number of days herein agreed upon for the completion 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 elsewhere set forth in these Contract Documents), as stipulated liquidated damages for such delay. 5. MEASUREMENT AND PAYMENT 5.01 QUANTITIES AND MEASUREMENTS: No extra or customary measure- ments of any kind will be allowed, but the actual measured 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. Itis understood and agreed that the actual amount of work to be done and material to be furnished under this contract may differ somewhat 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. 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 estttnated quantities contem- plated and contained in the proposal; provided, howe-rer, that in case the actual quantity of any item should become as much as 25% more than, or 25% less than the estimated cc contemplated quantity for such items, then either party to this Agreement, upon demand, shall be entitled to a reviaed consideration upon the portion of the work above or below 25% of the estimated quantity. 13 Any revised consideration in 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 of all the necessary labor, equipment and material, and 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 ha3 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 performing 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 preceding 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 4ay of the current month the total amount of the Engineer's statement, less 10 per cent of the amount thereof, which 10 per cent shall be retained until final payment, and further less all previous payments and all further sums ig understood, however, that in case the whole work be rear to completion and some unexpect- ed -ni unusual delay occurs dire to no fault or neglect on the part of the Contractor, the Owner may upon written recommendation of the Engineer pay a reasonaale and equitable portion of the retained percentage to the Contractor; or the Contractor, at the ow-nSr's option, may be relieved of the obligation to fully complete the work and, th:reupon, the Contractor shall receive payment of the balance due him under the contract subject only to the condi- tions stated under "Final Payment". 5.05 USE OF COMPLET'ZD PORTIONS: The Owner shall have the right to tako possession of and use any completed or partially completed portions of the work, notwithstanding the time for completing the entire work or 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. 14 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 accord- ance with the Contract Documents, the Engineer shall issue to the Owner and the Contractor his Certificate of Completion, and there- upon it shall be the duty of the Owner within" the (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 measure- ments and prepare final statement of the value of all wotk per- formed and materials furnished 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, ncr any provision in the Contract Documents, shall relieve the Contractor of the obligatio.° 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 subse- quently discovered evidence, Athl*'Id or nullify the whole or part of any certificate to such extent as may be necessary to protect himself from loss on account of: 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-contr9ctors or for material or labor. d. Damage to another contractor. When the above grounds are removed, or the Contractor provided a Surety Bord 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 PAYMENTS: 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, interest thereon at the rate of six (6) per cent per annum, unless otherwise specified, from date due as 15 provided under "Partial Payments" and Final Payments", until fully paid, which shall fully liquidate any injury to the Con- tractor 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 that 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 Mo3thod 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. 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 rentals on machinery and equipment, for the time actually employed or used on such Extra Work, plus actual transportation charges necessarily incurred tbgeth^r 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 directed 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 it 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 be determined by the Contractor. Unless otherwise agreed upon, the prices for ilia use of machinery 16 and equipment shall be determined by using 100 per ce:n t, unless otherwise specified, of the latest schedule of Equipment Owner- ship Expense adopted by the Associated General Contractors of America. Where practicable the terms and prices for the use of machenery 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 superintendence 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 main- tained 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 in involve Extra Work for which he should receive compensation or an adjustment 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 as to the payment therefor, and the Engineer insists upon its performance, the Contractor shall proceed with the work after making written request for written order and shall keep an accurate account of the "actual field cost" thereof, as provided under Method C. The Contractor will thereby perserve the right to sub- mit 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 questionscf 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 excep- tion. The Engineer shall, within a reasonable time, reply to such written exceptions by the Contractor and render hig final decision in writing. In case the Contractor should appeal zrom the Engineer's decision, and 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 notad 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 chosen by the two arbiters so selected; or if the arbiters fail to select a thir~ within ten (10) days, he shall be chosen 17 •Y by a District Judge serving the County in which the majorportion 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 information 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 arbiters, 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 any delay occasioned thereby. The arbiters 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 writing. 7. ABANDONMENT OF CONTRACT 7.01 ABANDONMENT BY CONTRACTOR: In case the Contractor should abandon and fail or refuse to resume work within ten (10) days after written notification from the Owner, or the Engineer, or if the Contractor fails to gdmply 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 on 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 receiving 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 materials, and equipment under contract for the work, may be held for use on the work by the owner or the surety on the performance and payment bonds, or arcther 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 Phall bu allowed as provided for under Section 6, Extra Work and Claims), it being understood that the use of such equip- ment anO materials will ultimately reduce the cost to complete the work and be reflected ih the final settlement. 18 Where there is no performance bond provided or in case the Surety should fail to commence compliance with the notice for completion hereinbefore provided for, 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 owner may thereupon, employ such force of men and use such machinery, equipment, tools, materials, and supplies as said owner may deem necessary to complete the work and charge the expense of such labor, machinery, equipment, tools, materials, and supplies to said Contractor, and expense so charged shall be de- ducted and paid by the Owner out of such moneys as may be due, or that way thereafter at any time become due to the Contractor under and by virtue of this Agreement. In case such expense is less than the sum which would have been payable under this contract if the same had been completed by the Contractor, then said Con- tractor shall receive the difference. 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 amount 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 :irculation 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 increase 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 credited with the difference. When the work shall have been substantially completed the Con- tractor his Surety shall be so notified and Certificates of Completion and Acceptance, as provided in Paragraph 5.06 herein- above, shall be issued. A complete itemized statement of the contract amounts, certified to 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, 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 is less than that which would have been the cost to the owner had the work been completed by the Contractor under the terms of this Contract; or when the Contractor and/or his Surety shall pay the balance shown to be due by theta to the owner, then all machinery, equipment, tools, materials, or supplies left 19 on the site of work shall be turned over to the Contractor and/or his Surety. Should the, coat to complete the work exceed the contract price, and the Contractor and/or his Surety fail to pay the amount due 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 equipmentand majetials,"shall be mailed to the Contractor and his Surety at the respective addresses designated in this contract; proviO.,dd, however, that actual written notice given in any manner will Fatisfy this condition. After mail- ing, or other giving of such nocice, 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 pro- perty. After fifteen (15) days from the date of said notice the Owner may sell such machinery, equipment, tools, materials or supplies and apply the net sum derived rrom such sale 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 remain on the work and belong to persona other than the Contractor or his Surety, to their proper ownere. The books on all operations provided herein shall be open to the Contractor and his Surety. 7.02 ABANDONMENT BY OWNER: T..n 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 b,ien included in payments to the Contractor and have not been wrought into the work. And thereupon, the Engineer shall I make an estimate of the total amount earled by the Contractor, I which estimate shall include the value o° all work actually com- pleted by said Contractor (at the prices -ttated in the attached proposal where unit prices are used), the value of all partially completed work at a fair and equitable pricey and the amount of all Extra Work performed at the prices agreed`-upon, or provided for by the terms of this contract, and a reasonable sum to cover the cost of any provisions made by the Contractor to carry the whole work to completion and which cannot be utilized. The Engineer shall then make a final. statement of the balance due 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 Agreement, 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 Contrac- tor, the balance shown by said final statement as due the Contractor under the terms of this Agreement. 20 DENTON, TEXAS 1966 - 1967 STREET ASSESSMENT PROGRAM DETAIL SPECIFICATIONS SECTION - 100 GENERAL 100.1 MATERIALS: These specifications are intended ro be so written that only materials of the beat quality and grade w,li be furnished. The fact that the specifications may fail to be sufficiently complete in some detail will not relieve the Contractor of fell responsibility for providing materials of high quality and protecting them adequately until incorporation in the project. The specifications for materials set out the minimum standard of quality which the Owner believes necessary to procure a satisfactory project. 3o 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. 100.2 WORKMANSHIP: These specifications contain detail instructions end descriptions covering the major items of construction and workman- ship necessary for building and completing the various units or elements of the 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 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 plans and specifications. 100.3 HANDLING MATERIALS NOT APPROVED: The Contractor shall remove from the site any materials found to be damaged, and any materials not meeting the specifications. These materials shall be removed promptly, unless the Engineer will accept the materials after repaying. Materials which are installed and found damaged or not acceptable, shall be removed and replaced. Inspection before installation shall not relieve the Contractor from responsibility to furnish good quality materials. 100- l SECTION 101 - CLEARING AND GRUBBING 101.1 GEARING SITE: Removal and disposal of all existing materials to tha extent as shown within construction limits on the plans, including asphalt surface, concrete steps, sidewalk, concrete slabs, culverts, masonery retaining walls, trees, brush and all other materials not to be incorporated in the completed work. 101.2 CLEARING: The entire project site shall be cleared of all trees, stumps, brush, logs, and rubbish except such trees and brush as may be designated by the Engineer to be left in place. The trees and brush designated for preservation shall be carefully trimmed as directed and shall be protected from scarring, barking, or other injuries during construction operations. 101.3 GRUBBINC: On areas required for construction of embankments, all stumps, roots, ets., shall be removed to a depth of at least We foot below the existing ground surface. On areas required for borrow sites and material sources, stumps, roots, etc., shall be removed to the complete extent necessary to prevent such objectionable matter from becoming mixed with the material to be used in construction. 101.4 CLEANING UP: All materials cleared and grubbed shall be disp,)sed of, and at the time of final acceptance of the project, the work shall present a neat appearance, free from all weeds, brush, rubbish, stumps, and brush. 101.5 MEASUREMENT AND PAYMENT: Clearing and grubbing work will not be measured for direct payment, but will be considered as subsidiary work pertaining to the various items of the Contract, and payment therefore shall be included in Contract unit prices as shown on the proposal. 101-1 102 - CONSTRUCTION REQUIREMENTS 102.1 PREPARATION FOR PLACING: EMBANKMENT: Prior to placing any embankment material, the area upon which it is to be placed shall be scarified or roughened by plowing to a depth of six (6) inches with furrows in general to be parallel to existing contours or perpendicular to the natural slope of the ground. It is essential that the ground be a roughened condition to provide good bond when the first lift of embankment is placed. PLACING EMBANKMENT: The embankment ahall be constructed to the elevation, lines, grades, and slopes shown on the drawings, as staked on the ground by the Engineer. No frozen material shall be pls-ed in any portion of the embankment nor shall materials be placed cn a frozen surface. No roots, trash, or debris will be allowed in the embankment. After the subgrade or base has been prepared as descriiied above, the placing of embankment material shall proceed as follows! Upon the wetted subgrade, suitable earthen material shall be placed in horizontal layers, not to exceed eight (811) inches in thickness, loose, and leveled by road grades, bulldozer, or other approved means. Each layer shall be thoroughly and uniformly wetted to approximately optimum • moisture content to obtain maximum density in the embank- ment. Final compaction shall be at least 95% Standard Proctor. The embankment shall be compacted with a sheeps- foot type roller, water and/or sand ballasted, having tamping feet uniformly staggered over its cylindrical surface and equipped with cleaners. Tamping feet shall be round, dia- mond, or square shaped with a face area of not less than five (5) nor more than seven.(7) inches. The roller shall be capable of exerting a foot pressure of one hundred seventy- five (175) pounds per square inch of bearing area when ballasted. Roller as specified by the Texas Highway Department will be acceptable, provided sufficient ballast is used to obtain the above specified foot pressure. Other types of rollers capable of obtaining the desired compaction may be used subject to the approval of the Engineer. At places where impossible to roll embankment with roller, material shall be hand or mechanical tamped until the compaction is equal to the 95% Proctor Density. Rolling shall be done on alternate areas, so as to keep the rollers constantly busy and successive trips or paths of the rollers shall overlap not less than one (1) foot. The roller shall pass over each 102-1 part of every layer a minimum of eight (8) passes, but in no case shall the density of the compacted layer be less than 95% of Proctor Density. One pass shall constitute the passing of one roller in one direction over any area with one overlap over the path of the preceeding • roller. 102-2 SECTION 103 - REINFORCED CONCRETE PIPE 103.1 GENERAL: The work under this item consists of furnishing all labor, material, and equipment for installation of storm sewer pipe as shown on the plans and provided in these specifications. 103.2 PIPE: Pipe used in the storm drainage system shall comply in all respects with the latest requirements of the Standard Speci- fications for Reinforced Concrete Culvert Pipe, ASTM Designation C-76-55. The concrete pipe shall be Class III. Concrete pipe shall be machine made and shall be steam cured in accordance with ASTM Specification C76057T for a sufficient time to obtain the required physical strength requirements. 103.3 LAYING CONCRETE TONGUE AND GROOVE JOINT PIPE: a. Handling: Care shall be exercised in loading, unloading, and hand- ling the pipe to avoid shock or damage. All material found during the progress of work to have cracks, flaws, or other defects will be rejected by the Engineer, and the Contractor shall promptly remove such defective material from the site of the work. b. Pipe Laying: The laying of pipes in finished trenches shall be commenced at the lowest point, so that spigot ends point in the direction of flow. All pipes shall be laid with ends abbutting and true to line and grade. :hey shall be fitted and matched so that when laid, they will form a sewer with a smooth and uniform invert. c. Jointing the Pipe: All pipe shall be closely jointed and sealed with stiff mortar, composed of one part portland cement and two parts sand, so placed as to form a durable watertight joint. The ends of pipe sb311 be thorm1hly cleaned and wetted before making the joint. After any section of pipe is laid and before any succeeding section is laid, the lower half of the bell of the pipe last laid shall be thoroughly plastered by troweling on at, even layer of mortar. The spigot end of the next section of pipe shall then be inserted, holding it as high as possible until it is fully inserted and then lowering it gently on the mortar. After the section is laid and uniformly matched, and the sections have been fitted as close as the construction of the pipe will permit, the lower half of the inner circumfere"ce of the joints of pipe shall be sealed and packed with mortar and finished smooth and even with the adjacent sections of pipe. Before this mortar has attained initial set, additional mortar shall then be applied from the outside and forced into the unfilled portion of the bell or groove to fill completely the annular space around the spigot or tongue. For tongue and groove pipe, a 103-1 bead shall be formed extending at least one inch on either side of the joint and of approximately semi-circular cross-section is used, it shall be formed by placing the mortar at approximately 45 degrees outward from the extreme edges of the bead. For pipes too small to permit finish of the inside surface of thq joint, a tight stopper of burlap or other equivalent materials shall be dragged through the pipe past the new joint to remove any fins of mortar. d. BEDDING: All pipe shall be bedded in a minimum of two (2") inches of washed pit run gravel, 3/4 inch to 1/4 inch in size. 103.4 INTERFERRENCE WITH EXISTING STRUCT-ORES: In excavating and backfilling trenches and constructing storm sewers, special care shall be taken not to remove or injure any existing gas, water, sewer, or other pipes, conduits or other structures without explicit instructions of the Engineer. If necessary, the Contractor shall, at his own expense, sling, shore up and/or otherwise secure and maintain a continuou3 flow in said structures, and shall repair any and all damages done to them. In the event a sewer line is broken o^ damaged in the course of the installation of the storm sewers, the pipe shall be replaced with cast iron pips of the same size, which shall extend a minimum of,two (2') feet on each side of trench excavation. The Contractor stall receive no payment for the repair of damage caused by the Contractor's operations. 103.5 BACKFI*Z : A granular backfill shall be used aF a backfill material for all pipe to be located within the curb limits. Good sound earth say be used as a backfill material for pipe outside the curb limits of the curb and gutter. The granular backfill shall be moistened to facilitate compaction and brought up in mechanical tamped layers not exceeding six (6") inch layers to a point twelve (12") inches over the top of the pipe. From that point to the surface the pipe may be backfilled with the granular material and jetted. 103.6 MEASUREMENT AND PAYMENT: Pipe shall be measured from center of n,anhole or end of pipe without am deductions for the length of intermediate specials. Fayment will be made at the price bid per foot for the pipe for the various sizes as set forth in the Proposal. The bid price shall include all costs for the complete pipe installation and shall include any and all incidental work not otherwise included in the bid items or otherwise provided for in these specifications. The price bid shall include all costs of materials, the cost of clearing and grubbing, the cost of taking care of conflicts with other utiliteis, the cost of sheeting or bracing in deep trench, and the cost of all classes of excavation, bedding, and backfill. 103-2 SECTION 104 - PREPARATION OF SUBGRADE INCLUDIVG TIME APPLICATION 104.1 DESCRIPTION: After removing all material to top of subgrade as shown on the Plans, the base shall be scarified to a depth of ten (10) inches, then wind-rowed, bladed, and prepared to receive the lime for stabilization. The subgrade shall then be pulverized completely with an approved pulvimixer until all lumps and clods are thoroughly pulverized. 104.2 METHOD OF APPLYING LIME: Lime shall be applied to the prepared subgrade so that the initial operation can be completed during the same day. The application of the lime in the subgrade shall be accomplished by the method hereinafter called the "Slurry Method". The required amount of lime and water shall be determined by a laboratory at the expense of the owner. 104.3 APPLICATION OF LIME TO SUBGRADE: The slurry will be applied with an approved distribvtor or water truck by making successive passes, if necessary, to apply the correct amount of lime. The distributor or water tank will be equipped with an agitator to keep the slurry in a consistent mixture. 104.4 INITIAL MIXING WITH A DISK HARLOW will °ollow line application immediately. After initial mixing, the subgrade will be lightly compacted with a pneumatic roller to protect against rain damage. The subgrade will be allowed to cure from twenty-four (24) to forty-sight (48) hours. 104.5 AT THE CONCLUSION OF INITIAL CURING, final mixing shall begin. The lightly compacted subgrade will be scarified to the required depth. A high speed rotary mixer, such as a Seamon-Andwall Pulvi-mixer, will 'follow until all clay clods will pass a one inch screen. The subgrade material shall then be brought to optimum moisture. 104.6 FINAL COMPACTION SHALL BE ACCOMPLISHED in single or multiple lifts, depending on the equipment used. In either case, the subgrade will be compacted from the bottom up to at least 95% of Standard Proctor. Moisture density test will be made continuously during compaction. 104.7 AFTER FINAL COMPACTION has been attained, the subgrade shall be moistened, if necessary, shaped to final lines, grades, and cross-section, and shall have a uniform surface, free from compaction planes. 104.8 FOLLOWING FINAL COMPACTION AND SHAPING, the roadway will be closed to all heav, traffic and allowed to cure for 5 days. At the conclusion 104-1 of the curing period, the flexible base will be laid in the normal manner. 104.9 The preparation of the subgrade, including lime application, will be a pay item. This will include all necessary items needed to complete the job, except the lime which will be a separate pay item. The limits of the prepared subgrade shall be the entire width of the street extending six inches back of the curb on both sides, All streets in the program shall receive lime stabilization, except when specifically exempted by the Engineer at the time of construction. SECTION 104-A PREPARATION OF SUBGRADE WHERE NO LIM IS REQUIRED 104-A.1 AFTER REMOVING ALL MATERIAL TO THE TOP OF THE SUBGRADE, a9 shown on the plans, the subgrade shall be watered and rolled so it will have as nearly as practicable a uniform density of not leas than 90% percent of the maximum dry density of samples of the materials as determined by the Modified Proctor Compaction Test. Prepared subgrade shall extend 6 inches back of curb on both sides. 104-A.2 ANY SOFT OR OTHERWISE OBJECTIONABLE MATERIAL encountered in the subgrade shall be removed by excavation and replaced with suitable material. The limits of any such excavation shall be determined by the Engineer. This will be payed for on a cubic yard basis as set up in the proposal. 104-A.3 PREPARATION OF SUBGRADE WHERE NO LIME APPLICATION IS REQUIRED will have no measurement for payment as a separate contract pay item. 104-A.4 PREPARATION OF SUBGRADE will not be paid for as a separate contract pay item, but costs thereof shall be included in such contract prices as are provided, which prices shall be the total compensation for furnishing of all labor, tools, materials, equipment necessary to complete the work. 104-2 1 SECTION 105 - FLEXIBLE BASE (CRUSHED STONES) 105.1 DESCRIPTION: Flexible base shall consist of crushed - run broken stone; and shall be constructed as herein specified in two courses in conformity witty the typical sections shown on the plans and to the lines and grades as established by the Engineer.

C. Coarse Aggregate: Coarse aggregate shall consist of washed gravel or crushed stone, and shall comply in every respect with the ASTM specifications for concrete aggregates designation C33-52T. The grading requirements as covered by the ASTM specifications are listed in part as follows: Sieve Size Percent Passing 2" 100 1~" 95 to 100 3/4" 35 to 70 3/8" 10 to 30 No. 4 0 to 5 D. Water: Water for concrete shall be clean and free from oil, acid, alkali, organic matter other harmful impurities. 107.1 Water which is suitable for drinking o7 for ordinary household use will be acceptable for concrete. 107.3 COMCRETE PROPORTIONS AND CONSISTENCY: Concrete shall be proportioted to give the necessary workability and strength and shall con.orm to the following governing requirements: Min. 28 Diy Min. Cement Max Size Max. Water Slump Compressive Bags Per of Coarse Gals. Per Inches Strength _ Cu. Yd. Aggregate Bag 3,000 5.5 WO 6.25 3-4 21500 5.0 1~ " 6.25 3-4 10500 4.0 1~" 7.5 3-4 The above strengths are the minimum that will be permitted. The average strength of the cylinder tests are expected to be 500 lbs. per square inch in excess of the minimum. The proportion of fine and coarse aggregates shall be such that the requirements of the following table are complied with: Maximum Size of Ratio of Coarse Aggregate to Fine Coarse Aggregate Aggregate on Basis of Dry and Rodded Volumes Mimimum Maximum 3/4" 0.6 1.5 1" and over 1.0 2.0 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. After materials are received at the project site, the Contractor shall determine by trial mixes, the proper mix•'and proportion to be used. Trial mixes shall be run at least 10 days prior to the pouring of any concrete of the first major structure and not less than 6 cylinders shall be made from each trial batch. In determination of the amount of water required For the mix, consideration shall be given to the moisture content of the aggregate. The net amount of water in the mix will be of the amount added at the mixer, plus the free water in the aggregate, and minus the absorption period. No water allowance will be made for evaporation after batching. The methods of measure of materials shall be such that the 107-2 proportions of water to cement can be closely controlled during the progress of the work and easily checked at any time by the Engineer or his representatives. To avoid unnecessary to haphazard changes in consistency, the aggregates shall be obtainer: from a source which will insure uniform quality and grading during any single day's operatioq and they shall be delivered to the work and handled in such manner that the variation in moisture content will not inter- fere with the steady production of concrete of reasonable degree of uniformity. All sources of supply shall be approved by the Engineer. The proportions of the mix shall be such as to produce concrete that can be puddled readily into the corners and angles of the forms and around the reinforcing without excessive opading, and without segregation or undue accumulation of water on the surface. 107.4 TESTS OF CONCRETE:, Frequent tests will be required by the Engineer throughout the work to determine the quality of concrete. These tests shall be made by an independent testing laboratory to be selected and paid by the Owner. Tests will in general be made on 6" by 1211 concrete cyliners, loaded in compression at 7 and 28 days, in accordance with standard method of the Am2srtcan Society of Testing Materials, designation: C39-42. Cylinders tested at 28 days shall not show strengths of not less than the specified 28 days compressive strength and cylinders tested at 7 days show strength not less than two-thirds (2/3)'0 the specified 28 days compressive strength. 107.5 GENERAL CONSTRUCTION REQUIREMENTS: Before starting work, the Contractor shall inform the Engineer fully as to the methods of construction he proposes to follow 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. Before constructing forms, the Contractor shall submit to the Engineer for his approval detail information, including necessary drawings and sketches of proposed from works, which shall be sufficiently complete to show all essential details. Concurrence on the part of the Engineer in any proposed construction methods, approval of equipment, or approval of forms shall not be considered as relieving the Contractor of the responsibility for the safety or correctness of his methods and adequacy of thin equipment safety or form carrying out the work in full accordance with contract. 107.6 FORMS: Forms shall be of wood or steel construction and shall be built mortar-tight and of material sufficient in strength to prevent bulging between supports and shall be set and maintained to the lines designated until the concrete is sufficiently hardened to permit form removal. During the elapsed time between the building of the forms and the placing of the con:rete, the forma shall be maintained in a manner to prevent warping and shrinking, All 107-3 details of form construction shall be subject to the approval of the Engineer, and the permission to place concrete will no,, be given until all of such work is complete to his satisfaction. Lumber for forms shall be properly seasoned and of good quality. It shall be free from loose or unsound knots, knot ~,clcs twists, shakes, decay and other imperfections which would affect itF strength or impair the finished surface of the concrete. The lumber used for facing or sheeting shall be surfaced on at least one aide and two edges and shall be sized to uniform thickness. Forms shall be suitably anchored and rigidly braced to prevent movement while placing concrete. Metal form ties of an approved type shall be used to hold forms to place. Such ties shall be of a type especially designed for use in connection with concrete work, and they shall have provision to permit ease of removal of the metal as hereinafter specified, The use of wire form ties will not be permitted except for minor special fo.-m areas when the use of rigid type metal ties would be impracticable. The use of metal form ties of type that are ercas-:: in paper or other materials to allow the removal of the complete tie, leaving a hole through the concrete structure, will not be permitted. Metal ties shall be held in place by devices attached to wells. 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 alignment 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. Burnt-.,g 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 (J") inch from the face of the concrete with a sharp chisel or nippers. All cavities produced by the removal of metal ties shall be care- fully cleaned and completely filled with re-te,~,pered sand cement mortar mix in proportion of one to three, and the concrete shall be left smooth and even. At the time of pleoing concrete, the forms shall be clear., entirely free from all chips, dirt, sawdust, and other extraneous matter. For wall and other locations where access to the bottom of Cle forms is not readily attainable otherwise, adequate clean-out openings shall be provided. 101-4 107.7 PLACING CONCRE M: The Contractor shall give the Engineer sufficient advance notice before starting to place concrete in any unit of the structure to permit the inspection of forma, the reinforcing steel placc,aent, and preparation for pouring. Unless authorized by the Engineer, no concrete shall be placed in any unit prior to the completion of the form work and the placement of the reinforcement. Whenever it is 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 to completed in the daylight hours. The sequence of placing concrete shall be as provided on tle plans or in thc, specifications. The operation of depositing and compacting the concrete 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 form. 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 approxi- mately 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 nearits final position as possible. The coarse aggregate shall be worked back from the face and concrete forced under and around the reinforcing bare and pipe or other inserts without displacing them. Depositing large quantities at one point in the forms and running or working it along the forms Will not be allowed. 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 motar flushed to the • surface of the forms by continuous working with concrete spading 107.5 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 concrete immediately 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 mass. The mechanical vibrator shall not be operated so that it will penetrate or disturb layers placed previously which have become partially set or hardened. The vibrator shall be of sufficient duration to accomplish thorough compacts,)n and complete embedn„ nt of reinforcement and fixtures but shall not be done to an extent that will cause segregation. Vibration shall be suppliemeted 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 set in the concrete, shall be placed into position and firmly anchored. 107.8 FREEZING WEATHER: When depositing concrete at or near freezing temperatures, the concrete shall have a temperature of at least 50 degrees F., but not more than 120 degrees F. when aggregates are heated. The concrete shall be maintained at a temperature of at least 50 degrees F. for not less than 72 hours after placing, or until the concrete has thoroughly hardened. When necessary, concrete materials shall be heated before mixing and heating apparatus such as stoves, salamanders, etc. shall be supplied to maintain the concrete at the required temperature. The Contractor shall be responsible for the protection of concrete placed under any and all weather conditions. 107.9 CONSTRUCTION JOINTS: The joint fo nned by placing plastic concrete in direct contact with concrete that has sttained ito initial set shall be deemed a construction joint. When concrete in a structure or a portion of s 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 construction joints shall have details equivalent to those shown on the plans for joints in similiar locations. 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. The top surface of a concrete placement which terminates at a horizontal construction joint shall have surface cement film removed and shall be thoroughly roughened as soon as practicable after the concrete has attained initial set. The surface at • 107-6 bulkheads shall be roughened as soon as the bulkhead forms are removed. Before. joining plastic concrete to concrete that has already set, the surface of the concrete in place shall be free from all loose materials, dirt or foreign matter; shall be wasted and scrubbed clean with stiff brooms and thoroughly drenched with water until saturated, and shall be kept wet until the plastic concrete has beer. placed. Immediately prior to the placing of additional concrete, all forms shall be drawn tight against the concrete in place, and the surface of the concrete in place shall be flushed with a coating of grout mixed in the proportions of one Fart of cement to two parts of sand. i If shown on the plans, construction joints shall be.prov:ded with cpnerete keyways, reinforcing steel dowels, and/or metal flaW'ng strips. The method of forming keys in deyed joints shall be such as to permit the-- removal of iorms without chipping,, breaking, or damaging the £ot±rrete Tn-dny manner. 107.10 CURING OF CONCRETE: Careful attentions shall be giver. by the contractor to the proper curing of all concrete in the structures. All concrete surfacer shall be kept moist by sprinkling or curing compound for a period of seven (7) days. In cold weather when curing may be retarded, this aeriod shall be extended as directed by the Engineer. All uncovered surfaces shall be protected from deformation or abrasion until thoroughly hardened. 107.11 REMOVAL OF FORMS: Forms for the portion of the structure • which do not require finish, may be removed in not less than the number of days set forth in the following table: forms for walls, columns, and sides of beams 4 days Forms and falsework under slabs, beams, and girders 7 days Forms for surfaces required to be fini-hed shall be removed when the concrete has cged not less than one-half day, nor more than two' (fj) days. Test specimens may be made for the determination of time or removal of forms is cold weather ar.d forms may be removed when test specimens, cured under like conditions to the curing of the structure, indicate the required seven (7) day strength has been obtained. 107.12 1INISY.Iu3: As soon as forms are removed, all cavities from tie holes and "honeycomb", shall be pointed up with 1:2 mortar, and properly cured so that the patches will not shrink or crack loose. 107.13 TRANSIT MIX CONCRETE: Transit mix concrete will be permitted in lieu of mixing on the job, provided all of the following conditions are met: . 107-7 a. All requirements otherwise specified for mixing on the job shall apply. b. Sufficient transit mix equipment shall be assigned exclusively to the project as required for continuous pburs. c. Satirifactory evidence shall be furnished that the delivery of concrete shall be continuous at regular and uniform intervals, without stoppages or interruptions. d. All concrete shall be deposited in the forms within 45 minutes after water has been added to the mix.

Bending of other grades shall preferably be done in the shop. Buds shall be true to the shapes indicated, and irregularities in bending for stirrups and ties shall be made around a pin having a diameter of not less than three times the minimum thickness of the bar. 168.3 STORING OF STEEL: Steel reinforcement shall be stored above the surface of the gro,.nd upon platforms, skids, or other supports and shall be protected as far as practicable from mechanical injury and surface deterioration caused by exposure to conditions produc- ing rust. When placed in the work it shall be free from dirt, scale, rust, dust, paint, oil or other foreign material. 108.4 PLACING AND MAINTAINING REINFORCEMENT: The steel shall be placed in the forms exactly as shown on the plans. It shall be maintained in place by wiring, by blocks of "one to two" mortar properly grooved to hold the bars from lateral displacement, or by any other effective means approved by the Engineer. In instances where two or three layers of reinforcement are shown, approved spacing blocks shall also be placed between each layer, spaced sufficiently close together to prevent appreciable sag of the bars. The slab reinforcement shall be raised off the forms by means of small concrete blocks of mixture as mentioned above and shall be wired to the longitudinal bars to maintain the proper spacing. It is very important that the length of bars, spacing and bending points in same be maintained as shown on the plans. Where splicing is necessary, the ars shall be lapped at lease 24 bar diameters, but no bar shall be spliced at points of maximum tension. At all corners and junctions, the reinforcement must tie together so that the strength of the junction shall equal the strength of the wall or member, with bends and laps of at least 24 bar diameters, 108.5 INSPECTION: All reinforcing steel is to be inspected after placing and approval by the Engineer. Not until this inspection has been made, and approval obtained, may the pburing of concrete proceed. 108.6 MEASUREMENT AND PAYMENTS Reinforcin5 steel will be paid for, at the unit prices bid for the various items of work requiring steel.
