ESTIMATED QUANTITIES. This agreement, includinL tLe specifications, plans and estimate, is intended to show clearly all work to be done and material to be furnished hereunder. The estimated quantities of the various classes of work to be done and material to be furnished under this contract 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. It is 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 the basis for payment under this contract shall be the actual amount of such work done and the material furnished. 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 contemplated and con- tained in the proposal; provided, however, that in case the actual quantity of any item should become as much as 25g more than, or 25g less than, the estimated or contemplated quantity for such items, then either party to this Agreement, upon demand, shall be entitled to a revised consideration upon the portion of the work above or below 25g of the estimated quantity; such .revised consideration to be determined by agreement between the parties, otherwise by the terms of this Agreement, as provided under EXTRA WORK. 16.

If such changes or alterations diminish the quantity of the work to be done, they shall not constitute the basis for a claim for damages, or anticipated profits on the work that may be dispensed with. If they increase the amount of work, and the increased work can fairly be classified under the specifications, such increase shall be paid for according to the quantity actually done and at the unit price established for such work under this contract; otherwise such additional work shall be paid for as provided under Extra Work. In case the OWNER shall make such changes or alterations as shall make useless any work already done or material already furnished or used in said work, then the OWNER shall recom- pense the CONTRACTOR for any material or labor so used, and for any actual loss occasioned by such change, due to actual expenses incurred in preparation for the work as originally planned. 17. EXTRA WORK. The term "Extra Work" as used in this contract shall be understood to mean and include all work that may be required by the ENGINEER or OWNER to be done by the CONTRACTOR to accomplish any change, alteration or addition to the work shown upon the plans, or reasonably implied by the specifications, and not covered by the CONTRACTOR'S Proposal, except as provided under Changes and Alterations in Paragraph 16 herein above. It is agreed that the CONTRACTOR shal.l.,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 Method (A) nor Method (6) 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, rentals on machinery and equipment, for the time actually employed or used on such Extra Work, plus actual transportation charges necessarily incurred, if the kind of equipment or machinery be not already on the job, together with all power, fuel, lubricants, water and similar operating expenses, also all necessary incidental expenses incurred directly on account of such Extra Work, and, a rateable proportion of premiums on Construction and Maintenance Bonds, Public Liability and Workmen's Compensation, 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 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 be determined by the CONTRACTOR. Unless otherwise agreed upon, the prices for the use of machinery and equifmnent shall he - termined by using the latest schedule of Equipment Ownership Expense adopted by the Associated•General 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 (15g) 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 herein dfined, 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 to involve Extra Work for which he should receive compensation, 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 (0). The CONTRACTOR will thereby preserve the right to submit the matter of payment to arbi- tration, as hereinbelow provided. 18. PRELIMINARY APPROVAL. No ENGINEER, supervisor, or inspector shall have any power to waive the obligations of this contract for the furnishing by the CONTRACTOR of good material, and of his performing good work as herein described, and in full accordance with the plans and specifications. No failure or omission of any ENGINEER, supervisor or inspector to condemn any defective work or material shall release the CONTRACTOR from the obligations to at once tear out, remove and properly replace the same at any time prior to final acceptance upon the discovery of said defective work, or material; provided, however, that the ENGINEER, his assistant or inspector, shall, upon request of the CONTRACTOR, inspect and accept or reject any material furnished, and in event the material has been once accepted by the ENGINEER, his assistant or inspector, such acceptance shall be binding on the OWNER, unless it can be clearly shown that such material furnished does not meet the specifications for this work. Any questioned work may be ordered taken up or removed for re- examination, by the ENGINEER, prior to final acceptance, and if found not in accordance with the specifications for said work, all expense of removing, re- examination and replacement shall be borne by the CONTRACTOR; otherwise the expense thus incurred shall be allowed as EXTRA WORK, and shall be paid for by the OWNER. 19. DEFECTS AND THEIR REMEDIES. It is further agreed that if the work or any part thereof, or any material brought on the ground for use in the work or selected for the same, shall be deemed by the ENGINEER as unsuitable or not in conformity with the specifications, the CONTRACTOR shall, after receipt of written notice thereof from the ENGINEER, forthwith remove such material and rebuild or otherwise remedy such work so that it shall be in full accordance with this contract. 20. 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 conducive to economy of construction; provided, however, that the order and time of prosecution shall be such that the work shall be substantially completed as a whole and in part, in accordance with this contract, plans and specifications and within the time of completion hereafter designated; 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 further agrees that he will commence work within ten (10) days after the date written notice to do so shall have been given to the CONTRACTOR, and will pro- gress therewith so that the work shall be substantially com- pleted in accordance with the terms of this Agreement * within Rm working days after the date of the written notice to commence the work. A "working day" is defined as a calendar day, not including Sundays or any legal holidays, in which weather or other conditions, not under the control of the CONTRACTOR, will permit construction of the principal units of the work for a continuous period of not less than seven (7) hours between 7 :00 a.m. and 6:00 p.m. By the term "substantially completed" is meant that the structure has been made suitable for use or occupancy and is in condition to serve its intended purpose, but still may require minor miscellaneous work and adjustment. 21. 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 employee of either, or by other Contractors employed by the OWNER, or by changes ordered in the work, or by strikes, lockouts, fire, and unusual delays by common carriers, and 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 CONTRACTOR shall give the ENGINEER prompt notice in writing of the cause of such delay. 22. HINDRANCES AND DELAYS. No charge shall be made by the CONTRACTOR for 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 stopping of said work shall be paid by the OWNER to the CONTRACTOR. 23. PRICE FOR 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 contained, the OWNER agrees to pay the CONTRACTOR the prices set forth in the Proposal hereto attached, marked "Exhibit C ", which has been made a part of this contract. And 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 specifications and requirements of the ENGINEER. 24.

Notice to do any work, to alter work, to cease work which the CONTRACTOR is obligated to do;or concerning any imperfections in work or any material furnished when given to any foreman or agent of the CONTRACTOR in charge of any operation of the work in the absence of the CONTRACTOR shall be considered as notice to the CONTRACTOR, provided any notice given under this paragraph shall be in writing. 31. CHARACTER OF WORKMEN. The CONTRACTOR agrees to employ only orderly, competent and skillful men_to do the work; and that whenever the ENGINEER shall inform him in writing that any man or men on the work are, in his opinion, incompetent, unfaithful or disorderly, such man or men shall be discharged from the work and shall not again be employed on the same without the ENGINEER'S written consent. 32.

RIGHT OF ENGINEER TO MODIFY METHODS AND EQUIPMENT. If at any time the methods or equipment used by the CONTRACTOR are found to be inadequate to secure the quality of work or the rate of progress required under this contract, the ENGINEER may order the CONTRACTOR in writing to increase their safety or improve their character and efficiency, and the CONTRACTOR shall comply with such order. If at any time the working force of the CONTRACTOR is inadequate for securing the progress herein specified, the CONTRACTOR shall, if so ordered in writing increase his force or equipment, or both, to such an extent as to give reasonable assurance of compliance with the schedule of progress. 34. SANITATION. Necessary sanitary conveniences for the use of laborers on the work, properly secluded from public observation, shall be constructed and maintained by the CONTRACTOR in such manner and at such points as shall be approved by the ENGINEER, and their use shall be strictly enforced. 35.

PROTECTION AGAINST CLAIMS OF SUB- CONTRACTORS, LABORERS, MATERIALMEN AND FURNISHERS OF MACHINERY, EQUIPMENT AND SUPPLIES. The CONTRACTOR agrees that he will indemnify and save the OWNER harmless from all claims growing out of the lawful demands of sub - contractors, laborers, workmen, mechanics, materialmen and furnishers, of machinery and parts thereof, equipment, power, tools, and all supplies, including commissary, incurred in the furtherance of the performance of this contract. When so desired by the OWNER, the CONTRACTOR shall furnish satisfactory evidence that all obligations of the nature hereinabove designated have been paid, discharged or waived. If the CONTRACTOR fails so to do, then the OWNER may at the option of the CONTRACTOR either pay unpaid bills, of which the OWNER has written notice, direct, or withhold from the CONTRACTOR'S unpaid compensation a sum of money deemed reasonably sufficient to liquidate any and all such lawful claims until satisfactory evidence is furnished that all liabilities have been fully discharged, whereupon payments to the CONTRACTOR shall be resumed in full, in accordance with the terms of this contract, but in no event shall the provisions of this sentence be construed to impose any obligation upon the OWNER to either the CONTRACTOR or his SURETY. 39. PROTECTION AGAINST ROYALTIES OR PATENTED INVENTION. The CONTRACTOR shall protect and save harmless the OWNER from all and every demand for damages, royalties or fees on any patented invention used by him in connection with the work done or material furnished under this contract; provided, however, that if any patented material, machinery, appliance or invention is clearly specified in this contract, then, and in that event, the cost of procuring the rights of use and the legal release or indemnity shall be borne and paid by the OWNER, unless such cost can be determined and included in the bid price at the time the proposal is submitted. 40. LAWS AND ORDINANCES. The CONTRACTOR shall at all times observe and comply with all Federal, State and local laws, ordinances and regulations, which in any manner affect the contract or the work, and shall indemnify and save harm- less the OWNER against any claim arising from the violation of any such laws and ordinances, whether by the CONTRACTOR or his employees. In case the OWNER is a body politic and corporate, the law from which it derives its powers, insofar as the same regulates the objects for which, or the manner in which, or the conditions under which, the OWNER may enter into contract, shall be controlling, and shall be considered as part of this Contract, to the same effect as though embodied herein. 41. LIQUIDATED DAMAGES FOR DELAY. And the CONTRACT ag s that time is of the essence of this contract, a•• that for e- h day of delay beyond the number of working d- s herein reed upon for the completion of the work -rein specified d contracted for (after due allowan for such extension o ime as is provided for under Ex sion of Time hereinabove), •'e OWNER may withhold perman ly from the * CONTRACTOR'S tot.. compensation, the sum for such delay. 42.

Which a..ed to he other compensate ion payable he 43. ASSIGNMENT AND SUBLETTING. The CONTRACTOR further agrees that he will retain personal control and will give his personal attention to the fulfillment of this contract and that he will not assign by Power of Attorney, or otherwise, nor sublet said contract without the written consent of the OWNER, and that no part or feature of the work will be sublet to anyone objectionable to the ENGINEER or the OWNER. The CONTRACTOR further agrees that the subletting of any portion or feature of the work, or materials required in the perform- ance of this contract, shall not relieve the CONTRACTOR from his full obligations to the OWNER, as provided by this Agreement. 44. 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 comply with the orders of the ENGINEER, when'such orders are consistent with this Contract, or with this Agreement, or with the Specifications hereto attached, then, and in that case, the Surety on the bond 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 construction bond, 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 paragraph 17, Extra Work); it being under- stood that the use of such equipment and materials will ultimately reduce the cost to complete the work and be reflected in the final settlement. 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: (a) 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 the expense's so charged shall be deducted and paid by the OWNER out of such moneys as may be due, or that 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 sum which would have been payable under this contract, if the same had been completed by the CONTRACTOR, then said CONTRACTOR shall receive the difference. In ease 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: (b) The OWNER under sealed bids, after five (5) days . notice published one or more times in a newspaper having a 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 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 therewith. ihhen 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 25 hereinabove, shall be issued. A complete itemized statement of the contract accounts, 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, or the OWNER, as the case may be, shall pay the balance due as reflected 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 them to the OWNER, then all machinery, equipment, tools, materials or supplies left on the site of the 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 the OWNER within the time designated hereinabove, and there remains any machinery, equipment, tools, materials or supplies on the site of the work, notice thereof, together with an itemized list of such equipment and materials, shall be mailed to the CONTRACTOR and his Surety at the respective addresses designated in this contract; provided, however, that actual written notice given in any manner will satisfy this condition. 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 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 from such sale to the credit of the CONTRACTOR and his Surety. Such sale may be made at either public or private sale, 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 persons other than the CONTRACTOR, or his Surety, to their proper OWNERS. 45. 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 ground that have not been included in pay- ments to the CONTRACTOR and have not been wrought into 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, (Exhibit C), the value of all partially completed work at a fair and equitable price, 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 pre- vious 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 notifi- ' cation by the CONTRACTOR the balance shown by said final statement as due the CONTRACTOR, under the terms of. this Agreement. 46. BOND. It is further agreed by the parties to this contract TM the CONTRACTOR will execute a bond in the sum of One hundred six thousand, three hundred.fifty seven dollars and fifty cents Dollars ($ 106 357.50 ) for the satis- factory performance of the work in accordance with this con- tract in the form provided for this purpose, and it is agreed that this contract shall not be in effect until such bond is furnished and approved by the OWNER. 47. 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 a reasonable time after the ENGINEER has given any direction, order or instruction to which the CONTRACTOR desires to take exception. The ENGINEER shall reply to such written exceptions by the CONTRACTOR and render his final decision in writing. In case the CONTRACTOR should appeal from the ENGINEER'S decision, any demand for arbitra- tion shall be filed with the ENGINEER and the OWNER in writing within ten (10) days after the date 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 3; party, except as follows; Contractor shall be responsible for any defective work or materials in the project for a period of one year after date of final acceptance 4 #. ADEQUACY OF DESIGN. It is understood that the OWNER has selected the ENGINEER named in this Agreement to prepare the plans and specifications, and all Supplements thereto; and agreed that the 01;NER will be responsible for the adequacy of the design, sufficiency of the plans and specifications, and the safety of the structure, provided the CONTRACTOR has complied with said plans and specifications, all modifications thereof, and additions and alterations thereto, approved by the ENGINEER. The burden of proof shall be upon the CONTRACTOR to show that he has complied with this contract, said plans, specifications, and all modifications thereof, and all additions and alterations thereto. 49. 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 third within ten (10) days, he shall be chosen by President of South Texas logineers Club Should the party demanding arbitration fail to name an arbiter within ten (10) days of the demand, his right to arbitrate shall lapse, and the decision of the ENGINEER shall be final and binding on him. Should the other party fail to choose 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, and shall not be open to objection on account of the form of proceedings or award. :AGE SCALES The Contractor shall take cog nuance of the following wage scales which have been adopted as the prevailing wages being paid in the community, and the Contractor shall tai.e these into account when preparing his bid.

Mortar shall be mixed thoroughly either in an approved type of batch mixer or in a water tight mortar box. CONCRETE FOR ALL PURPOSES Storing Materials: Materials shall be stored in such manner as to permit easy access for inspection and identification. Cement, lime, etc., shall be stored in a suitable weather -tight building so as to be protected from damage. Aggregates shall be stored in such a manner as to prevent intrusion of foreign materials and segregation of sizes. Measurement of Materials: The measurement of the materials, except water, used in batches of concrete shall be by weight. The fine aggre- gate, coarse aggregate, and mineral filler shall be weighed separately. Batch weighing of cement will not be required, since a full sack as hereinafter specified may be used as a basis of measurement. Allowance shall be made for the water content when moist aggregates are used. The quantities of each component material of the batch shall be determined by the Engineer, and no change will be made therein except by his order. The quantities of material per batch shall be based upon using full bags of cement. Batches involving the use of fractional bags will not be permitted. Weighing and Measuring Equipment: The capacity of the weighing equipment shall be adequate to permit the required weighing of materials without delaying the production of the mixer. The equipment used shall comply with the following requirements: (a) Types of Equipment Permitted: (1) Portable Platform Scales - Type A. This type shall consist of a portable platform scale having a container fastened securely to the platform. (2) Portable Platform Scales - Type B.

This type shall consist of a weighing container or hopper com- pletely suspended from the scale equipment. (4) Other Types - Other types of weighing equipment shall be used only with the written approval of the Engineer. (b) General Requirements: Containers shall be of suitable size and shape to handle the loads and discharge the same cleanly. Scales shall be the product of an established manufacturer, simple in design, easy of adjustment. Scales shall be such that they can be maintained within a maximum tolerance of one per cent of the net load being weighed. Separate scale units shall be used for each kind of material used unless the scale is equipped with multiple weigh beam. Working parts shall be protected to prevent wind borne material from falling on them and all parts shall be readily accessible for inspection and cleaning. The appliances used for placing materials within or upon the weighing equipment shall so regulate and control the quantity supply that accurate adjustment to the weights . required can be secured with little expenditure of time and labor. A convenient means shall be provided for the addition or the removal of small amounts of material to adjust the quantity to the exact weight per batch. (c) Water: The device used for measuring the quantity of water shall indicate the quantity in gallons and fractions thereof. The operating mechanism shall regulate the quantity required - for any given batch within one (1) per cent, and the supply inlet shall be cut off automatically when water is being discharged into the mixer. Condition of Equipment: All equipment, tools, and machinery used for hauling materials and performing any part of the work shall be main- tained in condition to insure completion of the work under way without excessive delays for repairs or replacements. Quality of Concrete: Concrete made of acceptable materials, of the propor- tions specified by the Engineer and in complete accordance with the requirements of the construction methods and details specified for the class of work involved, will be considered as of satisfactory quality. During the progress of the work, the laboratory or the Engineer will cast test cylinders for testing to main- tain a check on the compressive strength of the concrete actually being placed. The Contractor shall provide and maintain curing facilities approved by the Engineer for the purpose of curing test specimens. The cost of all materials used in test specimens and the cost of providing and maintaining curing facilities and testing shall be included in the unit price bid for concrete of the various classes. Mixing Conditions: The concrete shall be mixed in quantities required for immediate use, and any concrete which is not in place within thirty (30) minutes after being discharged from the mixer shall not be used. Retempering of concrete will not be permitted. In threatening weather, which in the opinion of the Engineer may result in conditions that will adversely affect the quality of the concrete to be placed, the Engineer may order postponement of the work. Where work has been started and changes in weather conditions require protective measures to be used, the Contractor shall provide adequate shelter to protect the concrete from damage from rainfall or damage due to freezing temperatures. In case it is necessary to continue mixing operation during rainfall, the Contractor shall provide protective coverings for the . material stock piles as well as for the concrete being placed. The covering for aggregate stock piles will be required only to the extent as may be necessary to control the moisture conditions in the aggregates so that adequate control of the consistency of the concrete mix may be main- tained. No concrete shall be mixed without the approval of the Engineer when the air temperature is at or below 40 degrees F. and falling, and then, only under conditions approved by the Engineer. Mixing and Mixing Equipment: The mixing shall be done in a batch mixer of approved type and size which will insure the uniform distribution of the material throughout the mass so that the mixture will be uniform in color and smooth in appearance. After all the ingredients are assembled in the drum, the mixing for other than pipe shall continue for a minimum time of one and one -half (1 -1/2) minutes. During the mixing time, the drum shall revolve at a speed of fourteen (14) to twenty (20) revolutions per minute. The mixer shall be equipped with a speed regulator to hold the mixer to its normal speed of revolution. The entire contents of the drum shall be discharged before any materials are placed therein for the succeeding batch. The concrete mixer shall be equipped with an autoa.atic timing device so constructed that it is put into operation when the skip is raised to its full height and dumping. This device shall satisfactorily lock the discharging mechanism to prevent emptying of the mixer until all the materials have been mixed together for the minimum time required. Whenever a concrete mixer is not adequate or suitable for the work, it shall be removed from the site upon a written order from the Engineer and a suitable mixer provided by the Contractor. Pick -up and throw -over blades in the drum of the mixer which are worn down more than twenty -five (25) per cent in depth shall be repaired or replaced by new blades. Concrete improperly mixed shall not be placed in the structure. Hand mixing of concrete will be permitted only for small placements or in the case of an emergency and then only on the authorization of the Engineer. When hand mixing is permitted, it shall be done on a water -tight platform. The fine aggregate and cement shall first be mixed until a uniform color is attained and then spread over the mixing board in a thin layer. The coarse aggregate shall then be spread over the fine aggregate and cement in a uniform layer and the whole mass turned as water is added. After all ingredients have been added, the mass shall be turned at least six times, or more if necessary, to make the mixture uniform in color and smooth in appearance. Hand mixed batches shall not exceed a two (2) bag batch in volume. Placing, Curing and Finishing:. The work of placing, curing, and finishing shall follow specifications set out elsewhere herein. Measurement: This item shall follow specifications set out elsewhere herein. Payment:, Payment will be made in accordance with the provision for payment set out elsewhere in the specifications. Ready Mixed Concrete: Ready mixed concrete complying with the specifications for Classes "A", "B", "C" and "AA" concrete and equipment herein will be approved when prepared under A.S.T.M. "Standard Specifications for Ready Mixed Concrete ", Serial Designation C-94, with the exception as follows: Paragraph 22: "Time of Hauling" now reads: "Discharge from the hauling container shall be completed within a period of 1 -1/2 hours ". This shall be changed to read: "Discharge from the hauling container shall be completed within a period of 30 minuttes after water has been added to the batch ". Batching Plants or Central Mixing Plants: Batching plants or central mixing plants shall be of sufficient capacity to keep the work progressing satisfac- torily. Machinery shall be in good condition and well maintained, and shall meet the approval of the Engineer as to adequacy, condition and operation. In case concrete is obtained from a commercial batching plant, such a plant shall be equipped with duplicate units, so that in case of a breakdown at least one unit will always be available for this project. Concrete Tests: During progress of the work and for each different mix of concrete, a set of three (3) standard six (6) inch concrete cylinders shall be made and tested where from 25 to 100 cubic yards of concrete are placed during any day's operation; also an additional set of tests shall be made for each 100 cubic yards or major fraction thereof over and above the first 100 cubic yards. Cylinders of each set shall be molded from the samples of concrete, one to be tested at seven (7) days and two to be tested at twenty -eight (28) days. Tests shall be in accordance with A.S.T.M. Serial Designation C -31, with curing according to Paragraph 7 -A. (a) Slump Test: A slump test shall be made for each fifty (50) or less cubic yards of concrete p accd in one operation. This test shall be made in accordance with A.S.T.M., Serial Designation D -132. DEPOSITING OF CONCRETE Preparatory Work: Before depositing concrete, debris shall be removed from the space to be occupied by the concrete and forms shall be thoroughly wetted. Reinforcement shall be thoroughly secured and approved by the Engineer. Handling and Ounveying: Concrete shall be handled from the mixers to the place of deposit as rapidly as practicable by methods which shall prevent the separation of or loss of the ingredients. It shall be deposited as nearly as practicable in its final position in the forms. It shall not be run along nor raked along the forms, but it shall be deposited so as to maintain, until the completion of the unit, a plastic surface approxi- mately horizontal. Forms for walls, or other thin sections of considerable height, shall be provided with openings or other devices that will permit the concrete to be placed in a manner that will avoid accumulation of hardened concrete on the forms or metal reinforcement. Chutes: When concrete is conveyed by chuting, the plant shall be of such size as to insure a practically continuous sliding in the chute, and of such design as will permit a free and ready movement of the discharge end of the chute along the forms, permitting the deposit of the concrete in place without raking of same. The angle of the chute with the horizontal shall be such as to allow the concrete to flow without separation of the ingredients, and the delivery end of the chute shall be as close as is possible to the point of deposit. The chute shall be thoroughly flushed with water before and after each run, or thoroughly cleaned by other means after each run, and water used for this purpose shall be discharged clear of the work. Concrete chutes shall be covered where necessary to prevent loss of material, and shall be of metal or fully metal lined. Vibrating Concrete: Concrete, during and immediately after depositing, shall be thoroughly compacted by means of internal vibrators of an approved type and size. The concrete shall thoroughly worked around the reinforcement and among the embedded fixtures and into the corners of the forms. The following paragraph shall apply to thin slabs and walls at points where thin slabs are deposited without requiring forms on both faces: Concrete shall be thoroughly tamped and puddled around the reinforcing and into position. Depositing Concrete Slabs: On the bottom and sloping slabs of structures, before depositing concrete, the earth shall be hand dressed to a firm bearing. If excavation is carried below grade, it shall be backfilled with concrete. Before depositing such slabs where shown on the plans, the earth surface on which the concrete is to be laid shall be covered with a layer of sisal kraft paper, or an approved equal, well lapped and fastened firmly in position. The concrete shall be deposited on top of this waterproof paper. This waterproof paper shall conform with General Requirements, Paragraph 2, A.S.T.M. Designation C171 -42T. Joining New Concrete to Old: Before depositing concrete against that which has set, the forms shall be retightened. Smooth surfaces of the set concrete shall be roughened to a depth of one -half (1/2) inch, thoroughly cleaned of foreign matter and laitance and saturated with water. To insure bond, the new concrete placed in contact with hardened or partially hardened concrete shall contain an excess of mortar. If required, the cleaned and saturated surfaces of the hardened concrete, including vertical and inclined surfaces, shall first be covered with a sprinkling of neat cement, against which the new concrete shall be placed. Construction joints shall be located as approved by the Engineer, and formed so as to least impair the appearance and strength of the structures. Unless specified otherwise in writing by the Engineer, no concrete shall be deposited against earth side walls. Where it is desired to cast concrete against forms' which are to be left in place, such process shall be subject to the approval of the Engineer. Removal of Water: Water shall be removed from the excavation before the concrete is deposited. Any flow of water into the excavation shall be directed through proper side drains to a sump, or removed by other approved methods which avoid washing the freshly deposited concrete. After the concrete has thoroughly hardened, water vent pipes shall be filled by grouting. Curing Concrete: Curing the concrete on this project is considered to be of major importance. Exposed surfaces of the concrete shall be kept wet continuously for a period of not less than seven (7) days after the time of depositing concrete. Concrete shall be cured with wet mats, or an equally efficient method approved by the Engineer. During the specified finishing operations, such covering, when required, shall be removed only for a minimum period of time and over a minimum area necessary. Mats used in curing shall be firmly anchored in place at all times. Concreting shall not be commenced until approved means for curing have been fully provided. Working on Concrete: No materials or equipment shall be stored on the walls or floor of structural members at any time, and forms or workmen shall not be allowed thereon while curing except for finishing and curing operations. When it becomes necessary, in the opinion of the Engineer, for loads to be aupported on such members, or for workmen to operate there- from, such protection of surfaces and bracing under slabs and beams shall be installed as the Engineer may direct. Finishing: Each and every part of the concrete work shall be carefully and neatly finished. Immediately after the removal of forms, all surfaces, whether to be exposed or not, shall have all honeycombed areas cut out and replaced or pointed up as required by the Engineer, using cement mortar of the same mixture as that used in the concrete. Surface finishing shall be as follows: Exterior surfaces shall be finished to 12" below surrounding grade. Exterior walls - rubbed. Interior of reservoirs - form finish, rough ridges removed. Floor of reservoirs - float finish. Unexposed columns - form finish, rough edges removed. Roof and interior - same as unexposed columns. Exposed intake - float finish, on exposed surfaces and floor. . Inner surfaces of concrete pipe or conduits - smooth or rubbed finish on sides and top. Bottom troweled finish. Valve boxes - exterior, rubbed finish; interior, form finish. Structural exposed surfaces, rubbed. Walks, curb and gutter - float finish. As soon as forms are removed, all necessary pointing up shall be done. When the pointing has set sufficiently to permit, all surfaces requiring a carborundum finish shall be wet with a brush and given a thorough rubbing wit:r a Number 16 or finer carborundum stone or an abrasive of =.n equal quality. The rubbing shall be continued . sufficiently to bring the surface to a paste, to remove all form marks or other projections, and to produce a smooth, dense surface without pits or irregularities. The use of cement to form a surface paste will not be permitted. The material which has been ground to a paste in this process shall be carefully spread and brushed uniformly over the surface and allowed to take a reset, the brushing to be in uniform striping. Areas to be float finished shall have the top surface floated with a wooden float until a slight excess of sand appears. Outer edges and joints shall be rounded with approved tools suitable to the radii. During the process of conditioning a completed structure for final acceptance, the surface above 1 foot below grade shall be cleaned from drip marks and discolorations, washed down and broomed so that the entire structure is left a neat, clean and uniform appearing finish and color. The interior surfaces of all structures, pipe, manholes, and storm sewers, shall be smooth. Form marks and rough spots shall be rubbed down with a carborundum stone. CONCRETE SURFACES SHALL NOT BE PAINTED WITH A CEMENT GROUT. Marking Concrete Construction: Concrete walks, steps, gutter and curb, and other surfaces shown to be marked, shall be marked with a steel edging tool where designated on the plans, or as designated by the Engineer.

Other types of material shall be placed in accordance with the directions of the manufacturer, but in a manner to secure a neat finish. Expansion joints on reservoirs or surge tanks or structures subject to hydrostatic pressure work shall be treated as follows: material, wh.ch has already be_gi;•b - -ins "place'shall be caulked i rAnt''by'Ydeans of an air hammer equipped with width of the expansion joint. After thoroughly caulking the cast in place joint shall be filled slightly above the concrete surface with an asphalt compound, poured on an approved primer paint coat. Where expansion joints are exposed and are not part of a structure under hydrostatic pressure, the expansion joint shall be neatly trimmed, flush with the surface of the concrete, upon completion of finishing. Construction Joints: Construction joints on reservoirs or other structures subject to hydrostatic pressure will not be permitted in the work except where shown on the plans. If for any reason a section of wall extending between expansion joints cannot be completed in a continuous operation with a plastic face of concrete at all times not in excess of thirty (30) minutes old, concrete in such section shall be removed and the section repoured in its entirety. Where construction joints are permitted, in structures designed for hydrostatic pressure, there shall be installed a continuous water -stop in the joint. This water -stop may be of copper if available, 16 gauge. If copper is not available, 16 gauge galvanized iron or other available material approved by the Engineer shall be used. Initial Set of Concrete: Where, in these specifications, a time limit of thirty (30) minutes has been set before which concrete shall be deposited in place after leaving the mixer, such time limit shall govern unless tests from time to time show, in the opinion of the Engineer, that such time limit should be shortened or that such time limit may be lengthened without affecting the characteristics of the concrete. No change in such time limit shall be made without the written approval of the Engineer. CONCRETE CRADLE Concrete cushion, cradle, or protection, where required, shall be constructed as shown on the plans, or where not shown on the plans, as directed by the Engineer. Where concrete cradle or cushion is constructed beneath pipe, the subgrade shall be prepared to dimension and form as shown on the plans.
