The Contractor may be required, within ten (10) days following the award of Contract, to furnish to the Engineer a detailed estimate and breakdown of the Contractor's estimate of cost conform- ing to the Contractor's bid, which estimate or breakdown shall be the basis of estimating periodic payments to the Contractor. This estimate shall be subject to the review and modification of the Engineer. 60. Construction Reports. The Contractor, as the work progresses, shall submit to the Engineer schedules of actual unit costs, which schedules shall be in such form and shall be supported as to correctness by such of the estimates upon which they are based, as to permit the preparation or revision of monthly estimates for partial payment. 61. Monthly Estimates - Payment. The Engineer, upon the first day of each month, or as early as is practical thereafter, will make an approximate estimate in writing of the materials incorporated into the work, the amount of work performed, and the value thereof at the contract unit prices. From the total amount so ascertained will be deducted such percentage as is outlined in the Special Provisions of this Contract, said percentage to be retained until after the completion of the entire work to the satisfaction of the Owner, and the remaining percentage of the amount so ascertained will be paid to the Contractor. In addition to the above and upon presentation of certified copies of invoices and freight bills, an estimate shall be made for payment of ninety percent (90%) of the value of acceptable, non-perishable materials intended for incorporation into the completed work, suitably stored at the site or other acceptable storage places, and which have not been used in the work prior to such estimate. G.C. - 15 No estimate other than a final estimate will be made where the value of the work performed since the last preceding estimate is less than $1,000.00. Not later than the 15th day of each month, the Owner will make payment to the Contractor on the basis of a duly certified estimate as prescribed above. 62. Final Estimate - Payment. The Engineer's final estimate shall be based upon a careful detailed estimate of the materials and equipment furnished and in- stalled in the completed improvement according to the provisions of these specifications. Final payment shall be made to the Contractor for any amount remaining due upon the final inspection, testing, and formal acceptance of the work by the Owner within thirty (30) days after the final completion and the acceptance of work. 63. Extra, Additional, or Omitted Work = Payment. The Owner, upon proper action by its governing body, may authorize changes in, additions to, or deductions from the work to be performed or the materials to be furnished pursuant to the provisions of the contract or any other contract documents. The Owner reserves the right to increase or decrease the contract quantity of minor bid items, and such additions and/or deductions shall not be a basis for claims for extra compensation other than that provided in the Proposal and these specifications. The Owner further reserves the right to increase or decrease the contract quantity of major bid items by an amount not to exceed twenty percent (20%) without altering the unit price bid shown in the Proposal. Change in the quantity of each bid item in excess of twenty percent (20%) may be accom- plished only after a satisfactory unit price has been negotiated between the Contractor and the Owner. A major bid item is defined as any bid item whose total dollar extension on the original contract equals more than ten percent (10%) of the total con- tract amount. Adjustments, if any, in the amounts to be paid to the Contractor by reason of any such change, addition, or deduction, shall be deemed by one or more of the following methods: A. By unit prices contained in the Contractor's original bid and incorporated in the construction contract. B. By a supplemental schedule of prices contained in the Contractor's original bid and incorporated in the construction contract. C. By an acceptable lump sum proposal from the Contractor. D. On a cost-plus basis. A cost-plus basis is defined as the cost of labor, materials and/or equipment which will be incorporated into the completed work, rental of construction equipment, and insurance plus fifteen per cent (15$) of said cost to cover all other miscellaneous expenses and profit. E. By negotiated changes in unit prices. G.C. - 16 fils*N fi".1 No claim for an addition to the contract sum shall be valid unless authorized by official order of the Engineer or Owner prior to the accomplishment of the work. 64. Measurements and Quantities. All measurements and determination of quantities shall be made by the Owner, through its proper officers, and these measure- ments shall be final and conclusive between the parties and nothing contained herein shall be construed as to deprive the Owner of any remedy or defense it may have under the same for any violation of the terms or conditions of this agreement. 65. Deduction for Uncorrected Work. If the Owner deems it expedient to accept work injured or not done in accordance with the contract, the difference in value, together with a fair allowance for the damages, shall be deducted. 66. Correction of Work After Final Payment. Neither the final payment nor any provisions in the contract documents shall relieve the Contractor of the res- ponsibility for negligence or faulty materials or workmanship within the extent and period provided by law and, upon written notice, he shall remove any defects due thereto and pay for any damage due to other work resulting therefrom, which shall appear within one (1) year after date of completion and acceptance. 67. Approval of Work. The authorized and herein described project shall be com- pleted in all respects and all materials used in its construction and all work thereon shall be in strict accordance with the specifications set forth herein and in full compliance with the said detailed plans therefor, attached hereto, and made a part hereof. All work shall be done in a first class work- manlike manner, under the direction, and to the satisfaction, of the Engineer and Owner, prior to being approved and accepted by the Owner. 68. Acceptance and Occupancy. Should it, in the judgment of the Owner, be deemed advisable and to the best interests of the public, to place in use or in service any portion or portions of the work prior to the completion and acceptance of the whole work, such completed portion or portions as may be ordered in writing by the Owner shall be placed in use or service and the Contractor shall agree thereto. Such action on the part of the Owner and the Contractor shall not be construed as a final acceptance of any portion or portions of the work by the Owner, nor shall such action relieve the Contractor from his liability to complete the whole of the work in accord- ance with the plans, specifications, and construction contract. The Con- tractor shall make no claim upon the Owner for any amount of extra compensation because of such action, but the said Owner shall not require the Contractor to pay the costs of operation of any portion of the work so placed in use or operation and the said Owner shall not, by its action, subject the Contractor to unreasonable expense in preparing separate portions of the work for use and service prior to the completion of the shole of the work. 69. Starting in Operation. The Contractor shall furnish a skilled operator to adjust and start all of the equipment erected and to put it in successful operation. After the equipment has been satisfactorily adjusted, the operator shall instruct the Owner's operators as to the proper methods of starting, adjusting, and caring for the equipment furnished and installed under these specifications. G.C. - 17 re\ 70. Delays - Unavoidable. If the Contractor is delayed in the completion of the work by any act or neglect of the Owner or by any other Contractor employed by the Owner, or by strikes, lockouts, fire, unavoidable casualties, or any causes beyond the Contractor's control, then the time of completion may be extended for a reasonable time, such reasonable time as the Owner may decide. The Contractor shall, within five (5) days from the beginning of any such delay, notify the Owner in writing of the cause of such delay. 71. The Owner's Right To Do Work. If the Contractor should neglect to prosecute the work properly or fail to perform any provisions of this Contract, the Owner, after three (3) days written notice to the Contractor and his surety, may, without prejudice to any other remedy he may have, make good such deficiencies and may deduct the cost thereof from the payment due the Con- tractor. 72. Completion of Work. The Contractor shall commence work specified herein within fifteen (15) calendar days after date of the Notice to Proceed issued by the Owner to the Contractor and shall complete the work as specified, ready for use, within the time specified in the Contract Proposal Form. In the event no written Notice to Proceed is issued by the Owner, the contract time as specified in the Proposal Form shall be counted from the first day of actual work on the project. All work shall be prosecuted in an orderly and diligent manner. The Con- tractor shall cooperate with and conform to requests of the Owner to expedite particular portions of the work or to suspend or transfer his operations on any portion of the work where such alteration of the Contractor's operations is deemed advisable by the Owner. 73. Work in Bad Weather. No construction work shall be done during stormy, freezing, or inclement weather, except that which can be done satisfactorily, and in a manner to secure first-class construction throughout, and then only subject to the permission of the Engineer. A normal amount of inclement weather shall not constitute a basis for an extension of time under this Contract. A day lost due to inclement weather shall be defined as a day on which the Contractor is unable to work four (4) or more hours on a major item of construction. Delays due to bad weather shall not be considered as a basis for time exten- sions unless the total bad weather time exceeds ten percent (10%) of the specified Contract time shown in the Proposal Form. Records concerning bad weather will be maintained by the Engineer, and it is this record that shall be used as a basis for any time extensions to be granted. 74. Properly Ordered Materials. To be considered properly ordered materials, the materials must be ordered from an acceptable supplier within fifteen (15) calendar days from the award of contract date. The order must call for delivery to meet the construction schedule required to complete the project within the specified time. No extensions of time will be considered for delays resulting from late delivery of materials unless those materials were properly ordered. G.C. - 18 75. Requests for Time Extensions. The Contractor shall submit a statement of the number of days lost each calendar month which he may intend using as a basis for a claim for time extension. Said statement shall be filed in duplicate with the Engineer at the same time the partial payment estimate is submitted by the Contractor. The Engineer shall return one (1) copy of the claim for time extension to the Contractor with appropriate comments. The Engineer's comments shall not be construed as a formal time extension, but will indicate the recommendations of the Engineer to the Owner. A normal amount of inclement weather shall not constitute a basis for an extension of time under this Contract. A day lost due to inclement weather shall be defined as a day on which the Contractor is unable to work four (4) or more hours on a major item of construction. Should work be stopped due to unfavorable weather conditions for an aggregate of ten percent (10%) or more of the total Contract time, an extension may he granted; if the total number of days lost due to inclement weather exceeds ten percent (10%) of the total number of Contract days. The basis for computing any such time extension shall be the weather condition records kept by the Engineer. 76. Liquidated Damages. In the event that the Contract has not been completed within the specified time (including approved time extensions), the cost of excess engineering services shall be deducted from monies due the Contractor as Liquidated Damages. The amount of liquidated damages chargeable per day shall be as shown in the Special Provisions and includes only actual payroll costs plus all payroll overhead items. On Contracts where no regular resident engineer is assigned, the Contractor shall be charged the daily rate shown in the Special Provisions for trips required of an engineer to make inspections after the stated completion date. No other liquidated damages will be charged for non-compliance within the specified time unless specifically stated in the Special Provisions. 77. Cleaning Up - Removal of Rubbish. The Contractor shall at all times keep the premises free from accumulations of waste material or rubbish caused by his employees or work. Rubbish and surplus material which may accumulate during and by reason of the work herein provided for shall be removed from the roadway, sidewalks, and intersecting street by the Contractor within three hundred (300) feet of the finished improvement, as fast as the improve- ment is completed, upon any part or section of the street, and such portion of the street left clean and in good condition. The Contractor will be required to remove all existing structures , foundations, rubbish and debris as a part of his Contract, and shall dispose of same to the satisfaction of the Engineer and such useful materials shall remain the property of the Owner. At the completion of the work, the Contractor shall remove all his rubbish from and about the building and all his tools, equipment, scaffolding, and surplus materials and shall leave his work clean and ready for use. In case of dispute, the Owner may remove the rubbish and surplus materials and charge the cost to the Contractor or the several contractors in proportion to the amounts as shall be determined to be just. G.C. - 19 78. Owner's Right to Withhold Certain Amount and Make Application Thereof. In addition to the payment to be retained by the Owner under the preceding pro- visions of these General Conditions, the Owner may withhold a sufficient amount of any payment otherwise due to the Contractor to cover: A. Payments that may be earned or due from just claims for labor or materials furnished in and about the performance of the work on the project under this Contract. B. For defective work not remedied.

Water from other sources shall be tested as required by the Engineer. 5. Admixtures. The Contractor may elect to use an air-entraining or other admixture provided the admixture is specifically approved by the Engineer. Admixtures to be approved either for plasticizing, densifying, air- entrainment , or acceleration of hardening of concrete shall, when added to the mixture , produce a concrete of specified strength in both 7-dav and 28-day tests. Documentary evidence of acceptability will be required when new or unknown admixi:ures are proposed for usage. 6. Storage of Materials . Cement and aggregates shall be stored at the work in such a manner as to prevent deterioration or intrusion of foreign matter. Any material which has deteriorated or which has been damaged in storage shall not be used for concrete even though it may have been previously approved by the Engineer. 7. Proportioning. Proportioning the "dry" constituents of all concrete mix- tures shall be accomplished by weighing. The Contractor shall provide adequate and accurate scales for this work. There will be no variance permitted in the minimum cement factor (sacks per cubic yard) as specified for the classes of concrete. The total quantity of mixing water per sack of cement including free water in the aggregates shall in no. case exceed the maximum specified herein. The Contractor shall be responsible for developing the proper proportions of aggregates , cement and water that will conform to the various require- ments of these specifications. The proportions as developed shall be submitted to the Engineer along with at least two sets of certified 7-day P.C. - 3 test results for review and approval. No concrete will be incorporated into the work until the proportions are approved by the Engineer. The proportions for the concrete mixture approved by the Engineer shall not be modified without the specific approval of the Engineer and then only as may be required to provide the proper consistency and workability. D. Mixing. The concrete shall be mixed in a batch type mixer of a type approved by the Engineer. The volume of the mixed material for each batch shall not exceed the manufacturer's rated capacity of the mixer, and the speed in revo- lutions of the mixer drum shall be in accordance with the manufacturer's recommendations . 1. General. Hand mixing will not be permitted except with the permission of the Engineer and then only in very small quantities or in the case of an emergency. In the event that the Contractor elects to use air-entraining admixture with Type II Portland cement for air-entraining concrete, the batch plant shall be equipped with a suitable automatic dispensing device which will proportion the air-entraining admixture accurately to each batch of con- crete. The device shall be calibrated and adjusted to deliver to each batch of concrete the quantity of admixture required to produce the speci- fied air content in the concrete. The air-entraining admixture shall be added prior to the addition of any cement or aggregate. 2. Truck Mixing. Truck mixers , unless otherwise authorized, shall be of the revolving drum type, watertight , and so constructed that the concrete can be mixed to assure a uniform distribution of materials throughout the mass. All solid materials for the concrete shall be accurately measured in accord- ance with the approved mix proportions and charged into the drum at the proportioning plant. Except as subsequently provided, the truck mixer shall be equipped with a tank for carrying mixing water. Only the pre- scribed amount of water shall be placed in the tank unless the tank is equipped with a device by which the quantity of water added can be readily verified. The mixing water may be added directly to the batch, in which case a tank will not be required. Truck mixers may be required to be pro- vided with means by which the mixing time can be readily verified by the Engineer. Mixing shall begin within thirty minutes after the cement has been added either to water or aggregate. Concrete transported in a truck mixer or agitator shall be discharged at the job and placed in its final position in the forms within 1-1/2 hours after the introduction of the mixing water to the cement and aggregate, or cement to the aggregate , except that in hot weather or under conditions contributing to the quick stiffening or setting of the concrete, the maxi- mum allowable time shall be reduced by the Engineer. Concrete shall be delivered at a rate such that no time intervals between two consecutive batches or loads shall exceed 45 minutes , unless other- wise permitted by the Engineer. The volume of the mixed material for each batch shall not exceed the manu- facturer's rated capacity of the mixer, and the speed in revolutions of P.C. - 4 The volume of the mixed material for each batch shall not exceed the manufacturer's rated capacity of the mixer, and the speed in revolutions of the mixer drum shall be in accordance with the manufacturer's recom- mendations. 3. Job Mixing. All concrete shall be mixed for a period of not less than 1-1/2 minutes after all materials , including water, are in the mixer. The entire contents of the mixer shall be removed from the drum before materials for the succeeding batch are placed therein. No mixer shall be operated above its rated capacity and no mixer of a rated capacity less than one sack shall be used. Concrete shall be mixed only in such quantities as are required for immediate use and shall be placed while fresh , before initial set has occurred. Any concrete in which initial set has begun shall be wasted. Retempering of concrete will not be allowed. E. Testing. Test specimens of the concrete will be taken by the Contractor under the direction of the Engineer to establish compliance with these speci- fications. These test specimens shall be made according to the latest require- ments of ASTM Designation C 31. Cylinders shall be tested in accordance with latest requirements of ASTM Designation C 39. In general, not less than two test specimens shall be made each day concrete is poured. The number of specimens required for each day's pouring shall be as follows : 25 cubic yards to 100 cubic yards 4 specimens 100 cubic yards or more 6 specimens For the purposes of representing the strength and quality of the concrete in the structures , the test specimen shall be cured adjacent to, and in the same manner as the concrete in the structure for the first seventy-two (72) hours. Test specimens shall be shipped to an accredited testing laboratory for test- ing and the results of the tests shall be transmitted directly to the Engineer.

General. Structural concrete is defined as all concrete, formed or unformed, used in construction, unless otherwise specifically designated on the plans or in these specifications. B. Forms. 1. Types and Erection. The Contractor shall provide suitable forms with smooth surfaces of ample strength and rigidly braced. The bracing shall be entirely adequate to prevent deviations from the correct lines. Forms shall be substantially watertight. No form shall be used which is not clean and of proper shape and strength, and in every way suitable for the purposes to which it is adapted. Deformed, broken, or defective forms shall be removed from the work . Before placing con- crete, the forms shall be cleaned and oiled or coated with other suit- able substances approved by the Engineer to prevent adherence of con- crete to the surfaces. All wooden forms shall be built of clean, sound, No. 1 yellow pine lumber, reasonably free from knots, dressed on all sides, and neatly fitted. Tongued and grooved material shall be used and securely fas- tened by nails, screws, or bolts to the ribs of supports. Suitable steel or plywood forms may also be used. Wooden forms for exposed walls shall be lined with plyboard or other smooth-surface-producing lining materials. No forms on any part of the work shall be removed without the consent of the Engineer, and the Contractor shall furnish a sufficient number of forms so that the work can be prosecuted rapidly and without delay in resetting previous forms. Forms shall be designed for the loads which will be placed upon them, and shall be solidly braced and anchored to prevent deformation while placing and vibrating concrete. If required by the Engineer, the Con- tractor shall submit detailed plans and/or design details of proposed formwork for approval by the Engineer. 2. Form Ties and Anchors. Forms shall be rigidly tied together to prevent warping or moving. Only form clamps of an approved pattern utilizing rods that will terminate at least one inch (1") below the faces of the work when the forms are removed will be used. Forms shall be firmly anchored against floating when concrete is deposited. Prior to placing any concrete in the forms, the interior of the forms will be thoroughly cleaned of all loose sawdust, wood pieces, paper, metal scraps, and other debris to the satisfaction of S.C. - 1 t'N the Engineer. On deep forms, doors or openings will be left in the base or bottom of the forms for this cleaning operation as well as placing and vibrating purposes. C. Placing Structural Concrete. The Contractor shall give the Engineer notice sufficiently in advance of placing concrete to permit the Engineer to properly inspect the forms and reinforcement. No concrete shall be placed until the forms and reinforcement are approved by the Engineer. 1. General. The method and manner of placing shall be such as to avoid the possibility of segregation or separation of the aggregates or the displacement of the reinforcing steel. Underwater placement of con- crete will not be permitted except with the approval of the Engineer. Even then, the concrete will be placed using "tremies" or other approved tools which will insure against mixing with water or the segregation of the concrete. The use of long chutes for conveying concrete from the mixing plant to the forms will not be permitted without the specific approval of the Engineer. Depositing of a large quantity of concrete at any point and running or working it along the forms will not be permitted, and every effort will be made to place the concrete directly as near its final place in the forms as possible. 2. Placing. Concrete shall be placed in the forms immediately after mixing. The method and manner of placing each batch of concrete shall be such as will prevent segregation of the concrete or displacement of the steel or forms. Special care shall be taken to fill each part of the forms by depositing concrete directly where it is required. Concrete shall be deposited in horizontal continuous layers, the thickness of which generally shall not exceed eighteen inches to twenty inches (18" - 20"). Each layer of con- crete shall be placed before the underlying layer has become set and shall be compacted in a manner that will entirely break up and obliterate the tendency to produce a construction joint between the layers. All concrete placed in walls or columns in excess of six feet (6' ) shall be spouted, tremied, or otherwise handled so that the actual free fall of the concrete will not exceed six feet (6' ). 3. Vibrating and Compacting. Concrete shall be vibrated, rammed, tamped, and spaded as required to thoroughly compact the entire mass. Vibrators used shall be of an approved type with a vibration frequency of not less than thirty-six hundred (3600) impulses per minute. A suf- ficient number of vibrators shall be used to secure the compaction of each batch before the next batch is placed without delaying delivery. There will be at least one standby vibrator in reserve and ready for service at all times. A full time operator for each vibrator will be available and without other duties during the placing operations. S.C. - 2 Vibrators shall not be pushed rapidly but shall he allowed to work themselves into the concrete mass and must be withdrawn slowly to avoid holes. The operation of depositing and compacting the concrete shall be conducted so as to form a compact, dense, impervious, artificial stone of uniform texture which shall show smooth faces when forms are removed. 4. Joints. Expansion joints shall be constructed where and as indicated on the plans. Unless otherwise shown or specified, the expansion joint material shall be set back from the exposed face of the concrete one-half (1/2) inch and the edges of the adjacent concrete shall be beveled at a forty-five degree (45°) angle from the face. Construction joints shall only be made in such places and in such manner that they will have the least possible effect upon the strength of the structure and at locations approved by the Engineer. All joints shall be roughened and thoroughly cleaned before joining new concrete to old. Where new concrete is added to old at a joint, the mix will be "enriched" by the addition of one full sack of cement to the first batch to be placed against the old concrete to provide a proper bond between the concrete sections. Bulkheads shall be used in constructing all joints other than horizon- tal. Shear keys shall be provided in joints as shown on the plans or as may be directed by the Engineer. Shear keys when formed into the concrete may be made by the insertion of, and subsequent removal of, a water saturated timber of the specified dimensions. D. Finish. All concrete surfaces shall be finished in accordance with the schedule called for on the plans. Where there is no finish specified on the plans and the surface is to be covered with backfill material or other- wise concealed from view, the finish shall be assumed to be Class 1, unless otherwise directed by the Engineer. Where there is no finish specified and the surface will be exposed to view, the finish shall be assumed to be Class 2, unless otherwise directed by the Engineer. 1. Class 1 Finish. Class 1 finish shall be a smooth finish, free of honey- comb, air pockets, rock pockets, excessive indentations, or protusions. Immediately after the forms have been removed, the Contractor shall remove all form bolts and tie wires to a depth of at least one-half inch (1/2") below the surface of the concrete. All holes and depres- sions caused by the removal of setting back of form bolts or tie wires shall be cleaned and filled with Portland Cement mortar composed of one (1) part by volume cement and two (2) parts sand. All rock pockets, S.C. - 3 "'1 honeycomb, and air pockets shall be chipped out, cleaned, and filled with mortar all in compliance with instructions of the Engineer. If, in the judgment of the Engineer, rock pockets are of such an extent or character as to materially affect the strength of the structure or to endanger the life of the steel reinforcement, he may declare the concrete defective and order the complete removal and replacement of that portion of the structure so affected. All mortar patches shall be carefully made using a very dry mortar tamped firmly in the void. The patches shall be kept wet for a period of three (3) days after which it will be inspected for shrinkage cracks. Excessive cracking will require complete removal and replacement of the patch. 2. Class 2 Finish. When Class 2 finish is specified on the plans or when no finish is specified and the surface is to be exposed in the finished work, the surface will first be given Class 1 surface finish. After the Class 1 finish is completed, the surface will be rubbed with a No. 16 carborundum brick or a mechanical finisher sufficiently to re- move all major protrusions , form ridges, and other unsightly bulges or burrs, such that when finished, the surface shall be reasonably smooth and neat in appearance. Immediately upon completion of the rubbing or finishing with the mechanical finisher and while the concrete is still less than seven (7) days old, the entire surface will be painted with a mortar mix of one (1) part Portland Cement and one (1) part fine sand. The sand shall pass a No. 16 screen. The cement mortar shall be vigor- ously scrubbed into the surface, while fresh, with a scrub brush or wood float. When the cement mortar has set sufficiently so that the sand particles will not drag out of pinholes, but before final set has taken place, the entire surface shall be thoroughly rubbed with dry burlap or a carpet float until a smooth surface free of mortar and of even tex- ture is obtained. This surface when finished shall be neat, relatively smooth, and capable of being left without paint, and still present a pleasing appearance. 3. Class 3 Finish. When Class 3 finish is specified on the plans or these specifications, the entire surface will first be given a Class 1 finish immediately after removal of the forms. Forms or vertical faces that are to receive Class 3 finish should be removed early, but only with the approval of the Engineer. Immediately after the completion of Class 1 finish, the entire surface shall be thoroughly wetted and rubbed with a paste. The rubbing shall be continued sufficiently to remove all form marks and projections, and fill all air pockets and voids. When the surface is smooth, dense, and free from pit marks or other irregularities, the past that has been worked up by the stone shall be spread smoothly and allowed to reset. If when the paste has set there are, in the judgment of the Engineer, discoloration, visible form marks, or other irregularities affecting the desired appearance, the Engineer may specify the following addi- tional treatment: S.C.- 4 The entire surface shall be coated with a layer of cement mortar composed of one (1) part normal Portland Cement, one (1) part White Portland Cement, and two (2) parts fine sand of such size that it will pass a No. 16 screen. The cement mortar shall be vigorously scrubbed into the surface with a scrub brush or wood float. When the mortar has set sufficiently so that sand particles will not drag out of pinholes in the surface, but before final set has taken place, the entire surface shall be thoroughly rubbed with dry burlap or a carpet float until a smooth surface, free of mortar, and of even tex- ture, color, and appearance is obtained. 4. General. The care and attention given to form work will have a direct effect upon the amount of work to be performed on the surface after the forms have been removed. The Engineer shall be the sole judge of the acceptability of the finished surface and when, in the judgment of the Engineer, the surface needs additional work, the Contractor shall perform this work in accordance with these instructions. E. Curing. Fresh concrete shall be adequately protected from weather damage and mechanical injury during the curing periods. Curing processes described herein may be used at the option of the Contractor. Whatever the curing process chosen, it shall be started as soon as it can be done without injury to the concrete surface. The following curing procedures may be used, subject to the approval of the Engineer: 1. Ponding (for slabs or footings). 2. Spraying. 3. Wet burlap, earth, or cotton mats. 4. Water proof paper or polyethylene plastic cover. 5. Membrane curing compound. Membrane curing compound will not be used when concrete surface is to be painted. The type of membrane curing compound chosen shall not discolor the concrete surface as determined by the Engineer. Where membrane curing compound is not used, the curing process shall be carefully adhered to as follows: 1. Surfaces being wetted by ponding, spraying, or wetted material shall be kept completely wetted with an excess of free water on the surface at all times for the first seventy-two (72) hours. After this period but for the remaining four (4) days , a wetting schedule will be followed whereby the concrete is wetted on a schedule approved by the Engineer. S.C. - 5 e n 2. Surfaces being protected by waterproof paper or polyethylene plastic cover shall receive special attention during the first seventy-two (72) hours to insure that there is actually free moisture on the surface of the concrete under the waterproof surface. The Engineer may require the removal of the cover and a wetting of the surface when, in his judgment, there is insufficient moisture for curing. After the first seventy-two (72) hours the cover shall be kept tightly in place for the remainder of the curing period. F. Cold Weather Concreting. During extreme weather seasons, placing of con- crete will be permitted only under the following conditions : 1. Temperature Control. The temperature of the concrete placed in the forms shall not be less than 60° F. , nor more than 100° F. To maintain this temperature range, the Contractor shall provide accept- able heating apparatus for heating the aggregates and the water, and in the case of hot conditions, the water may be cooled by addition of ice. 2. Concrete may be placed when the air temperature , in the shade, is 40° F. , and rising. No concrete shall be placed, regardless of present temperature, when the weather forecast promises freezing weather before final set of the concrete unless special means of heating and protection are used. Protection against freezing of the concrete is a Contractor's responsibility regardless of the weather forecast or climatic conditions at the time of placing of the concrete. a. Small structures and slabs may be protected by completely covering the fresh concrete with dry straw and canvas to a depth that in- sures protection. b. Large structures or vertical walls will be protected against freezing be enclosing the structure and heating with salamanders, heaters, or other devices capable of providing uniform and even heat throughout the structure. 3. Concrete placed in cold weather shall be protected from extreme tempera- tures as follows: a. The concrete shall be kept at a temperature of at least 50° F. , for the first seventy-two (72) hours. b. After the first seventy-two (72) hours and until the concrete is seven (7) days old, the concrete will be protected from freezing temperatures. c. Concrete adjacent to heaters or salamanders shall be insulated from the direct heat of the unit which may dry it out prior to being properly cured. S.C. - 6 n eTh d. Temperatures shall be measured by maximum and minimum thermometers furnished by the Contractor and installed adjacent to the concrete as directed by the Engineer. 4. Concrete slabs shall not be placed regardless of the temperature con- ditions if the supporting ground is frozen or contains frost. 5. The use of salt or other additive to prevent the concrete from freezing will not be allowed. 6. Concrete which has been frozen shall be completely removed and replaced as directed by and to the satisfaction of the Engineer, all at no added cost to the Owner. G. Removal of Falsework and Forms. Falsework supporting any concrete work shall not be removed or wedges loosened without the consent of the Engineer. In general, side forms or other non-load-carrying forms may be removed after twenty-four (24) hours to allow finishing in accordance with these specifications. Load-carrying forms or falsework shall not be removed until after the concrete has attained the seven (7) day strength, or until the concrete has set for seven (7) days. Where the new concrete is to be built upon these load-carrying forms and falsework, they may not be removed until the concrete has attained its twenty-eight (28) day strength or until the concrete is twenty-eight (28) days old. H. Miscellaneous. 1. Chamfer. All forms shall be filleted at all sharp corners which will be exposed to public view, unless otherwise directed by the Engineer. Triangular moldings used for fillets shall have two equal sides, and shall be of the following sizes : a. Walls and projections eight (8) to eighteen (18) inches = 3/4 inch b. Walls and projections eighteen (18) inches or over = 1-1/2 inch 2. Concrete Slabs on Grades. Concrete slabs on grades shall be con- structed as a system of independent slabs, formed by construction joints and expansion joints as detailed on the plans. The slabs shall be placed in checkerboard fashion, with a minimum time of twenty-four (24) hours between placements. When the drawings do not indicate the pattern of constriction or the location of joints, the slab shall be divided into approximate squares not exceeding 625 square feet in area. The preferable division lines for slabs shall be the column lines when such exist. 3. Concrete Floor and Slab Finishes. a. Concrete slabs shall be finished true to line and grade as shown on the plans. S.C. - 7 P'N. b. Screeds shall be set as required to produce the required grade before concrete is placed. c. After the concrete has been screeded off and has set up sufficiently to support a man's weight , it will be given an immediate wood float finish. This is a final finish for slabs to be covered with in- sulation and/or grouted on coverings. d. For surfaces to be covered directly by roofing felts, asphalt tile, rubber tile, or other covering set in mastic cement shall be hand-troweled once with a steel trowel following the operation of paragraph c. above. e. All other slabs shall be given a second hand-troweling and bur- nishing as well as a hardening and dust-proofing treatment by a colorless aqueous solution of zinc or magnesium fluosilicate applied in strict accordance with manufacturer's recommendations.
