Section I. Scope of the Project The work covered by this agreement is limited to those engineering services needed to implement a project to demonstrate the effectiveness of repairing inflow sources only in Minisystems 2, 4, 7, 8, 11 and 16, all as set out in the May 1980 Final Report of the Sewer System Evaluation Survey in the City of Fayetteville, Arkansas, by McCullough Associates, Inc:, and for which detailed construction plans and specifications have previously been prepared; said plans and specifications entitled "Sanitary Sewer System Rehabilitation; Contract Section I, Sanitary Sewer Line Reconstruction; Contract Section II, Sanitary Sewer System Rehabilitation;" Plans No. Fy-101. Section II. Scope of Engineering Services The Engineer shall provide at his own expense a suitable engineering staff and the necessary equipment to perform the required tasks as set out below. The engineering staff shall consist of engineers, engineering technicians, inspectors, clerical workers and other assistants as may be necessary to carry on the work in an efficient and expeditious manner. All of the sewer line reconstruction in Minisystems 2, 4, 7, 8, 11 and 16 in Contract Section I of the plans and specifications will be completed. The following line segments will be completed by force account methods by city forces: 2-3, 2-4, 2-5, 7-1, 7-2, 7-5, 7-9, 7-11, 8-1, 8-2. The balance: of the line segments will be completed by contract. In addition to theline segment replacement, all point source repairs in the above enumerated minisystems will be completed. The City will complete by force account methods all Code 9, 20, 21, 22 and 26 repairs (codes as per MWY plans and specifications for rehabilitation - Contract Section II). Required engineering services then would include the following: A. Flow Monitoring The engineer shall furnish all labor and equipment and conduct flow monitoring within the designated minisystems for a minimum of 30 days both before and after completion of the rehabilitation work to determine the effectiveness of the completed work. Flow monitoring shall be conducted during and following at least one significant rainfallevent as needed to accurately monitor the amount of inflow before and after completion of the rehabilitation work. A report will be prepared setting forth the results of the flow monitoring and indicating the effectiveness of the rehabilitation. The data will be presented in a way that will assist the City in making a deter- mination as to the extent of further rehabilitation throughout the sewer system. B. Preparation of Bid Documents and Engineering Surveillance of Construction The work proposed to be constructed by contract is included in previously prepared plans and specifications and includes work in both Contract Sections I and II. These plans, specifications and bid documents will be revised and combined into one set of plans and specifications to provide for the work actually proposed to be done. Additionally, the Engineer will provide the following services: 1. Furnish to the City all necessary copies of approved plans, specifications, notices to bidders and proposal forms. 2. Assist the City in the opening and tabulation of bids for construction of the project and consult with the City as to the proper action to be taken, based on the engineering considerations involved. 3. Assist in the preparation of formal contract documents for the contracts. 4. Furnish professional engineers to make periodic visits to the site (as distinguished from the services of a resident project representative) to observe the progress and quality of the executed work and to determine in general if the work is proceeding in accordance with the contract documents. In performing these services, the Engineer will endeavor to protect the City against defects and deficiencies in the work of the contractor; but he cannot guarantee the performance of the contractor, nor be responsible for the actual supervision of construction operations or for the safety measures that the contractor takes or should take. 5. Furnish the services of resident Project Representatives and other field personnel for necessary on -the -site observation of con- struction and for the performance of required construction layout surveys. The authority and duties of such resident Project Representatives are limited to examining the material furnished and observing the work done and to reporting their findings to the Engineer. The Engineer will use the usual degree of care and prudent judgment in the selection of competent Project Representa- tives, and the Engineer will use diligence to see that the Project Representatives are on the job to perform their required duties. It is agreed, however, that the Engineer does not underwrite, guarantee, or insure the work done by the contractor; and, since it is the contractor's primary responsibility to perform the work in accordance with the contract documents, the Engineer is not primarily responsible nor primarily liable for the contractor's failure to do so. Failure by any Project Representative or other personnel engaged in on -the -site observation to discover defects or deficiencies in the work of the contractor shall not relieve the contractor for primary liability therefor. 6. Consult and advise with the City; issue all instructions to the contractor requested by the City; and prepare routine change orders as required. 7. Review samples, catalog data, schedules, shop drawings, laboratory, shop and mill tests of material and equipment and other data which the contractor submits. This review is for the benefit of the City to insure general conformance with the design concept of the project and general compliance by the contractor with the information given by the contract documents. It does not relieve the contractor of any responsibility such as dimensions to be confirmed and correlated at the job site, appropriate safety measures to protect workers and the public, or the necessity to construct a complete and workable facility in accordance with the contract documents. 8. Prepare and verify monthly and final estimates for payments to the contractor and furnish to the City any necessary certifications as to payments to contractors and suppliers; assemble written guarantees which are required by the contract documents. Conduct, in company with the City, a final inspection of the project for conformance with the design concept of the project and compliance with the contract documents, and approve in writing final payment to the contractor. 10. Furnish to the City two copies of the revised contract drawings to show the work as actually constructed. P Section III. Payment In consideration of the performance of the foregoing, services by the Engineer, the City shall pay to the Engineer as full compensation for such services his actual cost plus a fixed fee. Cost shall mean direct salary, plus salary times a multiplier to cover indirect costs, plus reimbursable expenses at actual cost. The multiplier to cover indirect costs is hereby established for this project at 1.4. Reimbursable expenses shall include travel expenses when traveling outside Northwest Arkansas in connection with the project, rental expenses for equipment needed for completion ofthe work (for example, flow monitoring equipment), purchase of material and other expenses directly attributable to the project, including any work performed by subcontractors. A costceiling of $65,000 is hereby established. In addition to cost reimbursement, the City shall pay the Engineer a fixed fee in the amount of $16,000. Neither the cost ceiling nor the fee shall be increased unless the scope of the work is changed. The cost ceiling and the fixed fee were established on the assumption that work would be authorized so that the initial flow monitoring could commence between March 15 and May 1 of 1983, thus allowing the monitoring to be conducted during the period of normal spring rains. It was further anticipated that the rehabilitation work wouldbe completed during the summer of 1983 and that the final flow monitoring would commence at a time most likely to cover a period of rainfall needed to effectively monitor the effectiveness of the rehabilitation. It is hereby agreed that any material change in these dates would be cause for renegotiation. Payment shall be made monthly and shall be based on reimbursable costs plus the pro rata share of the fixed fee. Payment for engineering services under this agreement shall be made within 15 days after claim submittal and certification by the Engineer. Statements shall be accompanied by adequate itemization to fully indicate the basis of the charges. If any of the work designed or specified is suspended for an extended period of time or abandoned as a result of orders from the City, the Engineer shall be paid for work actually completed; payment therefor to be based insofar as possible upon the fees established herein. Section IV. Other Provisions of the Contract In connection with the project, the City's responsibilities shall include, but not be limited to, the following: 1.

I would suggest that the following sentence be added to the._first paragraph on page 2 under the heading "A. Flow Monitoring": Flow monitoring shall be done following such periods of.rain fall as are needed to accurately monitor the amount of infiltration before and after completion of the rehabilitation work. If the above modification meets with your approval, please incorporate it in the contract, execute the contract on behalf of McGoodwin, Williams & Yates, Inc., and forward the contract to the City Clerk for execution by the Mayor. By carbon copy of this letter, I am requesting the City Clerk to return one executed counterpart of the contract to you. Should you have any questions or comments, do not hesitate to contact me.

It should be noted that some of these provisions are clarified or superseded by provisions set out in the Instructions to Bidders. 2. Special Provisions of Arkansas Law. Attention is called to Sections 24 and 27 of the Instructions to Bidders, which point out the obligation of the Contractor to withhold state income taxes on wages paid and to comply with the provisions of Act 125 of the 1965 Arkansas Legislature regarding payment of certain taxes on material and equipment. 010-F.. SAFETY AND HEALTH REGULATIONS. The provisions covering safety standards and accident prevention as set out in the General Conditions are particularly called to the attention of the Contractor. In order to protect the lives and health of his employees under the contract, the Contractor shall comply with all pertinent provisions of the "Manual of Accident Prevention in Construction" issued by ',the Associated General Contractors of America, Inc., and shall maintain an accurate record of all cases of death, occupational disease and injury requiring medical attention or causing loss of time from work arising out of and in the course of employment on work under the contract. The Department of Labor of the State of Arkansas refers to the Federal Register (OSHA Regulations) for the guidance of contractors and the protection of workmen and the public. The Contractor shaLl familiarize himself with the provisions of the Register and shall comply with the rules and regulations provided therein. 010-2 Section 010 The Register requirements are enforceable by the Department of Labor,' and it se is the responsibility ofT�th'e='"'Cocitractor`'to see;;'that they are carried out. The responsibility for the.. interpretation ^and implementation of the provisions of the Register does not rest with 'the Owner, the Engineer, or their representatives. The Contractor alone shall be responsible for the safety, efficiency and adequacy of his plant, appliances, and methods and for any damage which may result from their failure or their improper construction, maintenance or operation. Although the Engineer and his personnel may recognize safety hazards and in such case will require that changes_ be. made to reduce or eliminate the hazards, the Engineer by such action does not take the responsibility as safety, engineer for the Contractor. Neither does such action indicate that the Engineer or his personnel are trained safety engineers. It'means only that a specific safety hazard has been recognized in the ordinary course of engineering inspection of the technical aspects of the work being done and such hazard has been called to -the attention of the Contractor. Any safety procedures initiated by the Engineer shall not be construed as ' supervision of the Contractor's work force, nor make him responsible for providing a safe place for the performance of the work by the Contractor or the Contractor's employees or those of the suppliers, his subcontractors, nor for access, visits, use, work, travel, or occupance by any person, as these responsibilities are covered under the provisions of the contract and the Contractor's insurance and performance bond and cannot be the responsibility of the Engineer. 010-F. QUALITY OF THE PLANS. The Plans ,have been made with care, but cannot be expected to be correct in every detail when some of the conditions to be encountered are underground. The Contractor shall work in close cooperation with the City operating personnel in locating underground lines in advance so as to reduce damage to the lines resulting in disruption of service and added cost to the Contractor. The Owner reserves the right to make normal changes in location, length, or grade of pipe as will facilitate construction, provide for better service, or reduce the construction costs to keep within the monies provided for this work. It is expected that the Contractor may find minor discrepancies as to dimensions or other details which might not fit the materials approved for construction. When such discrepancies or needed changes are found, the Engineer shall be notified. immediately. If such items are of significant importance, they shall be presented to the Engineer in writing. Where the Plans provide for rock excavation and other general conditions, it is understood that this information is placed in the Plans and proposal for general bidding information.and as an aid to the Contractor. The placing of such information in no way obligates the Owner as to the correctness of this information. It is the express intent of these Plans and Specifications that the Contractor has made his own investigation of conditions to be encountered, 010-3 and the filing of a bid hereunder constitutes the accep ance of this provision. 010-G. ELEVATION DATA. Elevations as shown are assumed elevations. 010-H. LANDS AND RIGHTS OF WAY.

The Contractor shall be responsible for locating and protecting or repairing and replacing such services. The various utility owners, the Owner (water mains and sewer), gas company (gas lines), telephone company (cable and conduits) and otters not named will cooperate with the Contractor in helping locate the underground services, but cannot afford to keep men on the job full time. Where the Contractor cannot make adequate repairs, the various utilities will make repairs to all services, and such costs will be charged to the Contractor. The Contractor shall make arrangements for this service with the various utilities either before the bid is presen�ed or before construction starts. The Plans do not indicate location of sewer services. The Contractor shall speedily repair all broken services and shall make sure that the line is clean and there are no obstructions or rough pipe left ro catch waste material. The Plans show a portion of the line to be laid adjacent to p wer lines. It shall be the responsibility of the Contractor to make any artjangements'with the power company for "tying off" poles.

The mixture shall be dry -mixed until it has a uniform color, after which water shall be added or the mixing continues until the mortar has a consistency such that it can be easily handled and spread with a trowel. Mortar or grout that has not been used within 30 minutes after water has been added shall not be used. 3. Manholes Steps. Steps shall be 10 inches wide and shall be constructed of steel reinforced fiberglass. Manhole steps shall be Perma-Step Model 100-2 as manufactured by. Utility Products, Inc., or equal. 150-C. MANHOLE CONSTRUCTION. Ii. Excavation for Manholes. Excavation for manholes will be made of such dimension and depth as to allow the construction of the manhole as shown on the Plans. No extra payment shall be made for manhole I. excavation, and all surface removal shall be in accordance with Section 095 of these Specifications. 2. Base. The concrete base shall have a minimum thickness of 8 inches and ' shall be poured on undisturbed earth. The base shall be poured so that the top of the base is a minimum of 2 inches and a maximum of 4 inches below the lowest pipe inside the manhole, except when the lowest pipe I. can be laid continuously through the manhole, the base may be poured to a point 2 inches below the centerline of the pipe, providing this point is not above invert of other pipes entering the manhole. The base shall have a minimum diameter of 8 inches greater than the outside diameter of the finished manhole barrel. 3. Connections to Manholes. Pipe connections to manholes are a constant ' source of potential trouble. In order to ensure that pipe will not break immediately adjacent to the manhole, care shall be taken that excavation for the manhole bottom is limited to the area to be filled I 150-1 ■ Manholes with concrete. The Contractor shall support pipe entering the manhole ALL OF THE WAY to solid bedding by backfilling under the pipe and up to mid-springline with concrete. 4. Invert. The invert of the manhole shall be hand -placed and shaped using grout as specified. The base and barrel of the manhole shall be cleaned thoroughly prior to placement of the invert. The invert shall be shaped and smoothed so that the manhole will be self-cleaning and free of areas where solids may be deposited as sewage flows through the manhole. The entire diameter of each pipe entering the manhole barrel shall be cut smooth with the inside edge of the manhole barrel and the invert shaped throughout from all inlet pipes to the outlet pipe. 5. Manhole Barrels. The barrel forms may be set as soon as the concrete base has cured enough to support the forms. The manhole barrel shall be of such construction so that the finished manhole will have an inside diameter of 4 feet 0 inches, plus or minus one-half inch. Prior to setting the forms in place, any water that may have accumulated in the excavated area shall be pumped out and the concrete base thoroughly cleaned, if required, of dirt and debris. Before pouring of the concrete begins, a 2 inch layer of grout mixture shall be placed in the bottom of the forms. The forms shall be removed after the initial set of the concrete so that holes may be cut in the manhole barrel for the installation of pipes which are to enter the manhole at points other than adjacent to the manhole base. After these pipes have been put in place, the barrel shall be repaired using a grout mixture. If honeycombing of the barrel is found to be present after removal of the forms, they shall be repaired as directed by the Engineer. 6. Manhole Steps. Manhole steps are required in all manholes 4 feet deep or more. During the construction of each manhole, steps shall be set in place on the inside of the manhole, beginning 2 feet above the bottom and placed not more than 18 inches below the top of the manhole. These steps are to be built to the dimensions shown on the Plans. The ends shall be firmly built into the wall, allowing the steps to project 5 inches from the inside of the manhole. 7. Manhole Heights. Manholes are to be built to the existing ground surface unless otherwise noted on the Plans or directed by the Engineer. When manholes are constructed in streets, the top of the poured manhole shall be left at such an elevation so that two rings of standard brick are required to bring the manhole ring to the finished elevation. A 3 inch wide by 2 inch deep keyway shall be left in the top of the poured manhole to hold the mortar for the first ring of bricks. All brick or block shall have full mortar joints on the bottom and sides. Every joint shall be formed at one operation by placing sufficient mortar on the bed and forcing the brick or block into it. Horizontal joints shall not exceed 3/8 inch and the vertical joints on the inside of the manhole shall not exceed 1/4 inch. The brick shall 150-2 Section 150 Manholes be plastered on both. the, inside and .outside with 1/2 inch of cement mortar. The plaster'''shall lie smoothly'i%id, and on the inside of the manhole all rough projections shall be removed. Details for the construction of manholes are shown on the standard detail sheet of the Plans. 8. Drop Manholes. Drop manholes, unless otherwise shown on the Plans, shall be constructed at all manholes where the difference in invert elevation between incoming and outgoing sewer is 2.5 feet or more. Dropmanholes shall be constructed of the same material and dimensions as are. standard manholes, the only difference being in the inlet arrangements as shown on the standard detail sheet. 9. Curing. Curing compounds option of the Contractor. the Contractor to protect curing process and to prot The Engineer shall, at his periods of extreme cold or or covers may or may not be used, at the However, it will be the responsibility of the concrete to prevent cracking during the !ct the manhole during freezing temperatures. discretion, prohibit pouring concrete during inclement weather. 10. Backfilling. The manhole shall be backfilled evenly around its perimeter no less than 12 hours after the forms have been removed. Extra care shall be taken to compact all backfill to the top of the highest pipe entering the manhole. All backfilling shall be in accordance with Section 146 of these Specifications. 11. Watertightness. All manholes constructed shall be watertight and show no visible evidence of.infiltration, and shall be tested in accordance with this Specification. After the manhole rehabilitation, including curing, has been completed, then the manhole shall be tested. The test shall be conducted by the Contractor in coordination with and at the direction of the Engineer. It is realized thatthere are certain conditions which will make manhole testing impractical or impossible to. perform, such as excessively high sewer flows requiring bypassing of the sewerage, manholes with depths exceeding 20 feet, etc. When conditions of this nature are encountered, no testing will be required. Manhole testing shall be accomplished by an exfiltration test. All incoming and outgoing sewer lines shall be plugged and the manhole filled with water up to the corbel section. If the water loss exceeds. the maximum allowable as shown below, the manhole shall have failed the test. Depth of Manhole Maximum Allowable Water Loss 0-8 feet 1 inch over 5 minutes Over 8 feet 1/8 gallon per vertical foot over 5 minutes All manholes which fail the test shall be repaired or a new manhole constructed. at the expense of the Contractor. 150-3 Section 16O Classification of Excavated Material CLASSIFICATION OF EXCAVATED MATERIALS 160-A. CLASSIFICATION OF EXCAVATED MATERIALS. Unless specifically provided for in the Proposal and Methods of Measurement and Payment, no provision is made for classifying excavation. In certain instances, however, provision is made in the Proposal for payment for rock excavation. Most of the work is generally in an area which might be underlain with broken chert, and in some instances may be solid sections of sandstone or limestone rock. To make a distinction between what should be classified as rock is very difficult. Consequently, the pay item for rock under this contract, if provision is made for such payment, will include: 1. All rock or chert in solid layers. 2. All consolidated chert which cannot be normally.excavated with a three-quarter yard backhoe without undue damage to equipment. Broken and badly weathered chert which can be readily removed will not be classified as rock. Where broken chert or rock is consolidated so that it is only removed with considerable difficulty by the use of a backhoe, or requires undue hammering with the bucket, or where heavy rippers are required, or where it is necessary that materials be blasted, it shall be classified as rock. Rock or broken chert, excavated in construction of right of way, will not be classified and paid for as rock. Measurement for rock excavation will be made on the basis of a ditch width 'of 16 inches greater than the outside dimensions of the pipe being laid. Rock excavated operation, and the Contractor initialed. shall be measured on the job at the end of each day's the quantity. of rock agreed upon between the inspector and or the Contractor's representative shall be recorded and 160-B. PAYMENT. There shall be no pay item for rock excavation in this contract. Rock excavation shall be considered subsidiary to pipe laying. 160-1 aeccion Lou Mandrel Test MANDREL TEST 180-A. GENERAL. The work to be included under this Section of these Specifications shall consist of providing all labor, equipment, tools, supplies, and incidentals necessary for mandrel testing all acrylonitrile-butadiene-styrene (ABS) composite sewer lines. ABS composite sewer lines shall be mandrelled in conformance with these Specifications with the following exception: any line segment which has only been partially replaced with ABS composite shall not be mandrelled. 180-B. TESTING. Flexible sewer pipes shall be mandrelled with a rigid device sized to pass 5 percent or less deflection (or deformation) of the pipe. The mandrel (go/no-go) device shall be cylindrical in shape and constructed with either 9 or 16 evenly spaced arms or prongs. Mandrels with less arms (in odd or even numbers respectively) will be rejected as not sufficiently accurate. The contact length of the mandrel's arms shall equal or exceed the nominal diameter of the sewer to be inspected. Critical mandrel dimensions shall carry a tolerance of 10.01 inch. Pipe dimensions as contained in ASTM 2680, latest revision, shall be used to I compute the mandrel dimensions. Allowances for pipe wall thickness tolerances or ovality (from shipment, heat, shipping loads, poor production, etc.) shall not be deducted from the base ASTM data, but shall be counted as a part of the I5 percent or lesser deflection allowance. The mandrel shall be hand pulled by the Contractor through all sewer lines. Any sections of sewer not passing the mandrel shall be uncovered and the I Contractor shall reround or replace the sewer to the satisfaction of the Engineer. These repaired sections shall be retested. I The inspection shall be conducted no earlier than 30 days after reaching final trench backfill grade, provided in the opinion of the Engineer that sufficient water densification or rainfall has occurred to thoroughly settle the soil throughout the entire trench depth. If this cannot be achieved in the time ' after installation prior to the project completion date, then the mandrel size shall be increased to measure 1/3 less of a deflection allowance. I Drawings of the mandrel with Contractor to the Engineer specification of pipe. I I I I complete dimensioning shall be furnished by the for his approval for each diameter and 180-1 Section 190 Air Testing LOW PRESSURE AIR TESTING FOR SEWER LINES 190-A. GENERAL. The work to be included under this section of the Specifications shall consist of providing, all labor, equipment, tools, supplies, and incidentals necessary for low pressure air testing of all sewer lines. Sewer line segments which have been scheduled for only partial replacement shall not be air tested. 190-B. TESTING. After the sewer line has been installed and manholes constructed, the Contractor shall proceed to air test all sewer lines to determine if sewers are free of breaks or other defects which would permit excessive infiltration or exfiltration. The test shall be performed according to the provisions of ASTM C828, latest revision, and these technical Specifications. The sewer line shall be air tested prior to backfilling or reconnecting the existing service lines. On all gravity flow sewers, the Contractor shall conduct low pressure air tests of the various sections of pipe by use of equipment manufactured for this purpose. The equipment shall include a regulator to avoid overpressurizing and possibly damaging an otherwise acceptable line. The equipment used shall be identical or equal to the Air-Loc system as manufactured by Cherne Industrial, Inc., Hopkins, Minnesota. The low pressure air test shall be conducted by plugging each opening in the reach of pipe to be tested, including all service wyes, tees or saddles. All plugs shall be braced against slippage due to internal pressure, and no one shall be allowed in the manhole during the testing procedure. One of the plugs provided must have an inlet tap or other provision for connecting an air. hose. After connecting the air control equipment to the air hose, monitor the air pressure so that the internal pressure does not exceed 5.0 psig. After reaching 4.0 psig, the air supply shall be throttled to maintain between 4.0 and 3.5 psig for at least 2 minutes in order to allow equilibrium between air temperature and the pipe walls. If plugs are found to leak, the Contractor shall bleed off the air, tighten the plugs, and again begin supplying air. After the temperature has stabilized, the pressure is allowed to decrease to 3.5 psig. At 3.5 psig, the Contractor shall begin timing to determine the time required for the pressure to drop to 2.5 psig. The pipe shall be presumed free of defects if the time, in seconds, for the air pressure to decrease from 3.5 psig to 2.5 psig is greater than that shown in the table below. .Pipe Size Minimum Time Pipe Size Minimum Time (Inches) (Minutes/100 Ft.)

CONSTRUCTION. 1. Pavement Removal, Pipe Protection Cover and Backfill. The pavement shall be removed, pipe protection cover placed, and trench backfilled in accordance with the pipe Specifications according to the type of pipe sewer being installed. All pavements which have been removed or damaged shall be repaired in accordance with these Specifications depending upon the type of pavement existing prior to construction. No payment for repair will be made_ for pavements damaged outside the width of allowable removal set out in Section 095 of these Specifications. a. Asphaltic Pavement Repair. After the trench has been backfilled, the trench shall be permitted to settle as set out in Section 146 of these Specifications. After this time the permanent repair shall be made as follows. The existing pavement shall be saw -cut and removed to a point 18 inches beyond the trench line limits, and brought to grade 3 inches below the top of the existing pavement. This area shall then be resurfaced by applying asphaltic cement prime coat at the rate of 0.25 gallons/square yard, followed by a minimum of 3 inches of hot -mixed, hot -laid asphaltic concrete, laid to an elevation matching the existing finished grade. The hot -mixed, hot -laid asphaltic concrete shall be compacted to 92 percent of theoretical density. One nuclear densometer test per asphaltic patch or repair shall be performed. The asphaltic pavement repair shall be deemed acceptable by the Engineer upon a passing nuclear densometer test at a location as directed by the Engineer. The cost of determining the compacted density shall be at the expense of the Contractor. 300-2 aecrion.5uu Any unacceptable. patch or repair shall{`be recompacted and retested at the Contractor`s*expense. b. Concrete Pavement and Asphaltic Overlaid Concrete Pavement Repair. After the trench has been backfilled, the trench shall be permitted to settle as set out in Section 146 of these Specifications. The trench area and an area 12 inches either side of the trench shall be brought to a grade 8 inches below the top of the existing concrete pavement. One-half (1/2) inch diameter reinforcing steel shall be drilled and grouted into the existing pavement at 12 inch centers both ways. Concrete shall_ then be poured into the excavated area to an elevation matching the existing finished grade, and troweled or brushed to match the existing finish. If the existing surface is a bituminous overlay, lamp black shall be mixed into the top 1 inch of the concrete to match the color of the surrounding pavement. c. Unpaved Driving Surface Repair. After the trench has been backfilled and allowed to settle as set out in Section 146 of these Specifications, the surface shall be brought to the existing grade with additional crushed stone base. 2.

Concrete shall consist of an approved Portland cement,, a fine aggregate, a coarse aggregate, and water mixed in the proportions specified. Air entrainment shall be accomplished by the addition of an air -entraining agent to the mixing water. The various materials entering into the composition of the concrete shall be such as will satisfy the requirements specified into this section. ' 800-B. MATERIALS. The materials used shall conform to the requirements as set out herein. No materials shall be used containing foreign matter, frost, or lumps or crusts of hardened substances. The gradation of the aggregate ' shall be determined by laboratory methods with sieves having square openings. The Contractor or producer shall use the size, length and character of screen and method of crushing and screening that is best suited to produce, the ' different sizes of aggregate required. 1. Water. All water used in mixing or curing shall be clean and free from injurious amounts of oil, salt, or other deleterious substances. Where ' the source of water. is, relatively shallow, it shall be obtained at such a depth, and the intake so enclosed as to exclude silt, mud, grass or other foreign materials. ' 2. Cement. Portland cement shall conform to the requirements of the current A.A.S.H.O. Specifications, Designation M 85, for Portland cement. Unless otherwise provided, Type I shall be furnished. Only one brand of. ' any one type of cement shall be used on the contract except by written permission of the Engineer. The Contractor may use, subject to the approval of the Engineer, Type III, a high early strength Portland cement. When a type of cement not specified on the Plans or in the Specifications is permitted by the Engineer, any additional cost shall be assumed by the Contractor. 3. Air -Entraining Agent. The air -entraining agent shall comply with the requirements of Standard Specifications of Air -Entraining Admixtures for Concrete, A.A.S.H.O. Designation M-154, and.shall be added to the mixing water in solution. The Contractor shall submit evidence based on tests made in a recognized laboratory to show that the air -entraining admixture conforms to the requirements of the latest revision A.A.S.H.O. M-154 (ASTM C206) for seven and 28 day compressive and flexural strengths and resistance to freezing and thawings, except as provided in the following paragraph. Tests for bleeding, bond strength and volume change will not be required. A "recognized" laboratory is any State Highway, Bureau of 800-i J G.. 11Vll VVV Concrete Public Roads or cement concrete laboratory regularly inspected by the Cement Reference Laboratory of the National Bureau of Standards. Tests may be made upon samples taken from a quantity submitted by the Contractor for use on the project or upon samples submitted and certified by the manufacturer as representative of the admixture to be supplied. An exception to the requirements in the preceding paragraph is the case of admixtures which are manufactured by neutralizing Vinsol resin with caustic soda (sodium hydroxide). When the Contractor proposes to use such an admixture he shall submit a certification concerning the admixture in the following form: "This is to certify that the product (trade name) as manufactured and sold by the (company) is an aqueous solution of Vinsol resin that has been neutralized with sodium hydroxide. The ratio of sodium hydroxide to Vinsol resin is one part of sodium hydroxide to (number) parts of Vinsol resin. The percentage of solids based on the residue dried at 105° C. is (number). No other additive or chemical agent is present in this solution." When the Contractor proposes to use an air -entraining admixture which has been previously approved, he shall submit a certification stating that the admixture is the same as that previously approved. If an admixture offered for use is essentially the same (with only minor difference in concentration) as another previously approved material, a certification will be required stating that the produce is essentially the same as the approved admixture and that no other admixture or chemical agent is present. Either prior to or at any time during construction the Engineer• may require that the admixture selected by the Contractor be further tested to determine its effect upon the strength of the concrete. When so tested, seven-day compressive strength of concrete made with the cement and aggregates in the proportions to be used in the work and containing the admixture under test in an amount sufficient to produce 5 percent ±1 percent entrained air in the plastic concrete shall be not less than 88 percent of the strength of concrete made with the same materials and with the same cement content and consistency but without the admixture. The percentage reduction in strength shall be calculated from the average strength of at least five standard 6 inch by 12 inch cylinders of each type of concrete. Specimens shall be made and cured in the laboratory in accordance with the requirements of the latest revision of the A.A.S.H.O. T-126 (ASTM C 192) and shall be tested in accordance with the requirements of the latest revision of A.A.S.H.O. T-22 (ASTM C 39). The percentage of entrained air shall be determined in accordance with the requirements of the latest revision of A.A.S.H.O. T-152 (ASTM C 231). Cement furnished in sacks shall weigh not less than 94 pounds net per sack. the use of cement salvaged from used or discarded sacks will not be allowed, nor will the mixing or alternate use of different brands of 800-2 oection ovu. Concrete cement be permitted.. Cement. placed storage shall be suitably protected. Any retrogres°sion'.in qualitoccurring during the storage period will be cau`se''for rejection. If the cement furnished shows erratic behavior under the field conditions incident to the pouring and placing of the concrete, or in regard to the strength of the finished product, or in the time of the initial or final set, the Contractor will at once, without notice from the Engineer, cease the use of that brand of cement and furnish cement of such properties as to ensure work •of a quality satisfactory to the Engineer. 4. Coarse Aggregate. The coarse aggregate shall consist of crushed stone or gravel. A coarse aggregate consisting of a combination of crushed stone and gravel shall be used only when specifically approved by the Engineer.

Proportioning. The concrete mixture shall be .proportioned as. so to secure a workable and durable concrete, as hereinafter specified. Class A(AE) Concrete Designated Size of Coarse Aggregate - 11" to No. 4 Square Openings Minimum Cement Factor --------------- 6 Bags per Cubic Yard ' Maximum Net Water Content per Bag (94 lbs.) of cement --_----- 5`11 gallons Range in Slump ----------------------2 to 4 inches IAir Content (Range) ----------------- 4 to 6 percent. The Contractor shall provide laboratory design mixes for approval by the Engineer. The concrete materials shall be proportioned as determined by ' the Engineer using the Absolute Volumes method in accordance with the requirements for each class specified above. It is the -intent of the 1 800-5 ■ . Concrete above limits to produce a concrete with a minimum 28 day compressive strength of 3,000 pounds per square inch. The compressive strength will be determined from testing cylinders which have been sampled from concrete used in the structure, cured under the same conditions as the structure, made and compression tested in accordance with the current American Association of State Highway Officials Specifications, Designation T-23, covering the testing of molded cylinders. If the strength required for the class of concrete being produced is not secured with the minimum cement content specified, additional cement shall be used at the Contractor's expense. When the Contractor proposes to use a new source of material which has not been proven by past experience, he shall submit samples sufficiently in advance so that trial mixes can be prepared and the concrete tested as provided above. The air entrainment shall be accomplished by adding to the mixing water the proper amount of air -entraining agent in solution. The Engineer shall determine by means of trial batches on the project the amount of admixture required to produce an air content within the range specified. The mixer shall be equipped with a suitable automatic dispenser for adding to the mixing water the desired amount of air -entraining agent. The dispenser shall be constructed and connected so that the Inspector can make ready determination of the amount of air -entraining admixture entering the mixing water. 3. Consistency. Concrete shall have a consistency such that it will be workable in the required position. It shall be of such a consistency that it will flow around reinforcing steel but individual particles of the coarse aggregate when isolated shall show a coating of mortar containing its proportionate amount of sand. The consistency of concrete shall be gauged by the ability of the equipment to properly place it and not by the difficulty in mixing or transporting. The quantity of mixing water shall be determined by the Engineer in accordance with Section 800-B.2 above and shall not be varied without his consent. In general, the slump for concrete, placed by the usual methods or by the vibration method, shall comply with the requirements of Section 800-C above, unless otherwise authorized by the Engineer. 800-D. SAMPLING AND TESTING. Compliance with the requirements shown in Section 800-C above shall be determined in accordance with the current methods of the American Association of State Highway Officials. During the progress of the work, concrete test cylinders or beams will be made by the Engineer and tested for compressive strength or modulus of rupture for the purpose of checking the field control of the quality of the concrete. The cost of working, transporting, testing and all other costs associated with sampling and testing will be borne by the Contractor. 800-E. HANDLING AND STORAGE OF MATERIALS. The handling and storage of concrete aggregates shall be such as to prevent segregation and the admixture 800-6 Section 800 Concrete of foreign materials. on suitable platforms. stockpiles sufficiently edge of the piles from be satisfactory to the The.Engineer may require;,ithat the aggregates be stored Coar`.'se%'sand fine aggregate& shall be stored in separate removed from each other to prevent the material at the becoming intermixed. The location of stockpiles shall Engineer. All cement shall be stored in suitable weatherproof buildings which will protect the cement from dampness. Provision for storage shall be ample and the shipments of cement as received shall be separately stored in such a manner as to provide easy access for the identification and inspection of each shipment. Stored cement shall meet. the test requirements at any time after storage when a retest is ordered by the Engineer. On small jobs, storage in the open may be permitted by written authorization from the Engineer, in which case a raised platform. and ample waterproof covering shall be provided. Copies of cement records shall be furnished the Engineer, showing in such detail as he may reasonably 'require, the quantity used during the day or run at each part of the work. Cement held in storage for a period of over three months, or cement which, for any reason, the Engineer may suspect of being damaged, shall be subject to a retest before being used on the work. I. 800-F. MEASUREMENT OF MATERIALS. Materials shall be measured by weighing, except as otherwise specified or where other methods are specifically authorized by the Engineer. The apparatus provided for weighing the I aggregates and cement shall be suitably designed and constructed for this purpose. Each size of aggregate and the cement shall be weighed separately. The accuracy of all weighing devices shall be such that successive quantities ' can be measured to within 1 percent of the desired amount. Cement in standard packages (sack) need not be weighed, but bulk cement shall be weighed. The mixing water shall be measured by volume or by weight. The water measuring device shall be susceptible of control accurate to plus or minus 1/2 percent ' of the capacity of the tank. All measuring devices shall be subject to approval. ' Where volumetric measurements are authorized by the Engineer for projects where the amount of concrete is small, the weight proportions shall be converted to equivalent volumetric proportions. In such cases, suitable allowance shall be made for variations in the moisture condition of the 'aggregate, including the bulking effect in the fine aggregate. When the aggregates contain more water than the quantity necessary to produce ' a saturated surface -dry condition as contemplated in Section 3. above, representative samples shall be taken and the moisture content determined for each kind of aggregate. ' When sack cement is used, the quantities of aggregates for each batch shall be exactly sufficient for one or more full sacks of cement and no batch requiring fractional sacks of -cement will be -permitted. I 800-7 Concrete W 800-G. MIXING CONCRETE. I 1. Ready -Mixed Concrete. The use of ready -mixed concrete will be permitted as approved by the Engineer. If the use of ready -mixed concrete is permitted, all provisions set out heretofore for site -mixed concrete shall be observed except as herein modified. When the specified slump is 3 inches or less, the tolerance shall be plus or minus 1/2 inch. When the specified slump is greater than 3 inches, the tolerance shall be plus or minus 1 inch. Ready -mixed concrete shall be understood to mean any concrete which is proportioned and mixed in a central plant and hauled to the work site in agitator trucks of approved type, or in non -agitating equipment when approved by the Engineer; or concrete which is proportioned in a central plant and mixed in approved transit mix trucks en route to the site of the work; or mixed completely in a truck mixer at the point of delivery following the addition of mixing water. Mixer may be stationary mixers or truck mixers. Agitators may be truck mixers or truck agitators. Each mixer and agitator shall have attached thereto, in a prominent place, a metal plate on which is plainly marked for the various uses for which the equipment is designed, the capacity of the drum container in terms of volume of mixed concrete and the speed of rotation of the mixing drum and blades. The truck mixer, when loaded to manufacturer's rated capacity, which shall not exceed 57-1/2 percent of the volume of the drum of the mixer, shall be capable of combining the ingredients of the concrete within the specified time into a thoroughly mixed and uniform mass and of discharging the concrete with a satisfactory degree of uniformity. The agitator, when loaded to manufacturer's rated not exceed 80 percent of the volume of the drum shall be capable of maintaining the mixed concrete and uniform mass and of discharging the concrete degree of uniformity. capacity, which shall ' and of the agitator, in a thoroughly mixed with a satisfactory Mixers and agitators shall be operated within the limits of capacity and speed of rotation designed by the manufacturer of the equipment. Units designated as agitators shall not be used in connection with truck mixing. When a stationary mixer is used for the complete mixing of the concrete, the mixing time shall be the same and the mixer and mixer operation shall comply substantially with the provision set out herein for site -mixed concrete. When a truck mixer is used for complete mixing, each batch of concrete shall be mixed not less than 70 nor more than 100 revolutions of the drum or blades at the rate of rotation designated by the manufacturer of the equipment as mixing speed. Additional mixing, if any, shall be at the speed designated by the manufacturer of the equipment as agitating speed. Section 800 Concrete When a truck mixer is used for transpor-tirig concrete which has been completely mixedin aa"stationary mixer, mixing during transportation shall be at the speed designated by the manufacturer of the equipment as agitation speed, and the volume of the batch shall not exceed 80 percent of the gross drum volume. Concrete shall be delivered to the site of the work and discharged from the truck mixer or agitatorinto the forms complete within 1-1/2 hours after the introduction of the mixing water to the cement and aggregates except that in hot weather, or under other conditions contributing to quick stiffening of the concrete, the maximum allowable time may be reduced by the Engineer. Each batch shall be accompanied by a time slip issued at the hatching plant bearing the time of departure. Slump tests shall be made from time to time of individual samples taken at the beginning, midpoint and end of the load. If these slumps vary by more than the tolerances specified above, the mixer or agitator shall not be used unless the condition is corrected. Mixers and agitators shall be examined daily for changes in condition due to the accumulation of hard concrete or mortar or wear of blades. The pickup and throw -over blades shall be replaced when any part of section is worn 1 inch or more below the original height of the manufacturer's design. A -copy of the manufacturer's design, showing dimensions and arrangement of blades, shall be available at all times. The concrete, when discharged, shall be of the consistency and workability required for the job -without the use of additional mixing water. The rate of discharge shall be controlled by the speed of rotation of drums in the discharge direction with the discharge gate fully open. - Unless otherwise approved by the Engineers, the mixed concrete shall not. be less than 50°F, and not more than 90°F at the time of placing. When approved in writing by the Engineer, central -mixed concrete which is designed for the -purpose may be transported in approved non -agitating equipment. Bodies of this equipment shall be smooth., watertight, metal containers, equipped with gates that will permit control of the discharge of the concrete. Covers shall be provided for protection against the weather. The concrete shall be delivered to the site of the work in a thoroughly mixed and uniform mass and discharged with a satisfactory degree of uniformity. Placement in forms shall be completed within 30 minutes after introduction of the mixing water to the cement and aggregates. If the concrete furnished shows erratic behavior under the field conditions, or in regard to strength of the finished product as shown by beams or cylinder tests or in the time of initial or final set, the Contractor will, at once, without notice from the Engineer, cease the use of ready -mixed concrete until such corrections in procedure are made as to ensure work of a quality satisfactory to the Engineer. 800-9 YVYaV.. VVV Concrete The organization supplying concrete shall have sufficient plant capacity and transporting apparatus to ensure continuous delivery at the rate required. The rate of delivery of concrete during concreting operations shall be such as to provide for the proper handling, placing and finishing of the concrete. The rates shall be such that the interval between batches shall not exceed 20 minutes. The methods of delivering and handling the concrete shall be such as will facilitate placing with the minimum of rehandling and without damage to the structure of the concrete. 2. Rand Mixing. When hand mixing is authorized it shall be done on a watertight platform and in such a manner as to ensure a uniform distribution of the materials throughout the mass. Mixing shall be continued until a homogeneous mixture of the required consistency is obtained. 3. Retempering. The concrete shall be mixed only in such quantities as are required for immediate use and any which has developed initial set shall not be used. Concrete which has partially hardened shall not be retempered or remixed. 800-H. HANDLING AND PLACING CONCRETE. General. In preparation for the placing of concrete, all sawdust, chips, and other construction debris and extraneous matter shall be removed from the interior of forms. Struts, stays and braces, serving temporarily to hold the forms in correct shape and alignment, pending the placing of concrete at their locations, shall be removed when the concrete placing has reached an elevation rendering their service unnecessary, and these temporary members shall be entirely removed from the forms and not buried in the concrete. All concrete shall be placed before it has taken its initial set. Concrete shall be placed so as to avoid segregation of the materials and the displacement of the reinforcement. The use of long troughs, chutes and pipes for conveying the concrete from the mixer to the forms shall be permitted only on written authorization from the Engineer. In case an inferior quality of concrete is produced by the use of such conveyors, the Engineer may order discontinuance of their use and the substitution of a satisfactory method of placing. Open troughs and chutes shall be of metal or metal lined. Where steep slopes are required, the chutes shall be equipped with baffles or be in short lengths that reverse the direction of movement. All chutes, troughs, and pipe shall be kept clean and free from coatings of hardened concrete by thoroughly flushing with water after each run; water used for flushing shall be discharged clear of the structure. When placing operations would involve dropping the concrete more than 5 feet, it shall be deposited through sheet metal or other approved pipes. As far as practicable, the pipes shall be kept full of concrete during placing and their lower ends shall be kept buried in the newly placed concrete. After initial 800-10 Section 800 Concrete set of the concrete, the forms shall not be jarred and no strain shall be placed on the ends of reinforcin'g bars which`project. All concrete, during and immediately after depositing, shall be thoroughly compacted.. The compaction shall be done by mechanical vibration subject to the following provisions: 1. The vibration shall be internal unless special authorization of other methods is given by the Engineer or as provided herein. 2. Vibrators shall be of a type and design approved by the Engineer. They shall be capable of transmitting vibration to the concrete at frequencies of not less than 4,500 impulses per minute. 3. The intensity of vibration shall be such as to visibly affect a mass of concrete of 1 inch slump over a radius of at least 18 inches. 4. The Contractor shall provide a sufficient number of vibrators to properly compact each batch immediately after it is placed in the forms. 5. Vibrators shall be manipulated so as to thoroughly work the concrete around the reinforcement and imbedded fixtures and into the corners and ' angles of the forms. Vibration shall be applied at the point of deposit and in the area of freshly deposited concrete. The vibrators shall be inserted and ' withdrawn out of the concrete slowly. The vibration shall be of sufficient duration and intensity to thoroughly compact the concrete, but shall not be continued so as to cause segregation. Vibration shall not be continued at any one point to the extent that localized areas of grout 'are formed. Application of vibrators shall be at points uniformly spaced and not farther apart than twice the radius over which the vibration is visibly effective. ' 6. Vibration shall not be applied directly or through the reinforcement to sections or layers of concrete which have hardened to the degree that the concrete ceases to be plastic under vibration. It shall not be used to make concrete flow in the forms over distances so great as to cause ' segregation, and vibration shall not be used to transport concrete in the forms. ' 7. Vibration shall be supplemented by such spading as is necessary to ensure smooth surfaces and dense concrete, along form surfaces and in corners and locations impossible to reach with the vibrators. IS. The provisions of this article shall apply to precast piling, concrete cribbing- and other precast members except that, if approved by the Engineer,, the manufacturer's methods of vibration may be used. ' Concrete shall be placed in horizontal layers not more than 12 inches thick except as hereinafter provided.. When less than a complete layer is placed in 1 800-11 Concrete one operation, it shall be terminated in a vertical bulkhead. Each layer shall be placed and compacted before the preceding batch has taken initial set to prevent injury to the green concrete and avoid surfaces of separation between the batches. Each layer shall be compacted so as to avoid the formation of a construction joint with a preceding layer which has not taken initial set. When the placing of concrete is temporarily discontinued, the concrete, after becoming firm enough to retain its form, shall be cleaned of laitance and other objectionable material to a sufficient depth to expose sound concrete. To avoid visible joints as far as possible upon exposed faces, the top surface of the concrete adjacent to the forms shall be smoothed with a trowel. There a "feather edge" might be produced at a construction joint, as the sloped top surface of wingwall, an insert form work shall be used to produce a blocked out portion in the preceding layer which shall produce an edge thickness of not less than 6 inches in the succeeding layer. Work shall not be discontinued within 18 inches of the top of any face, unless provision has been made for a coping less than 18 inches thick, in which case, if permitted by the Engineer, the construction joint may be made at the underside of the coping. Immediately following the discontinuance of placing concrete, all accumulations of mortar splashed upon the reinforced steel and the surface of forms shall be removed. Dried mortar chips and dust shall not be puddled into the unset concrete. If the accumulations are not removed prior to the concrete becoming set, care shall be exercised not to injure or break the concrete -steel bond at and near the surface of the concrete when cleaning reinforcing steel. 800-I. DEPOSITING CONCRETE UNDER WATER. Concrete shall not be deposited in water except with the approval of the Engineer, and under his immediate supervision; and in this case, the method of placing shall be as hereinafter designated. Concrete deposited in water shall be seal concrete. To prevent segregation, it shall be carefully placed in a compact mass, in its final position, by means of a tremie, a bottom dump bucket or other approved method, and shall not be disturbed after being deposited. Still water shall be maintained at the point of deposit and the forms under water shall be watertight. For parts of structures under water, when possible, concrete seals shall be placed continuously from start to finish. The surface of the concrete shall be kept as nearly horizontal as practicable at all times. To ensure thorough bonding, each succeeding layer of seal shall be placed before the preceding layer has taken initial set. A tremie shall consist of a tube having a diameter of not less than 10 inches, constructed in sections having flanged couplings fitted with gaskets. The tremies shall be supported so as to permit free movement of the discharge end over the entire top surface of the work and so as to permit rapid lowering when necessary to retard or stop the flow of concrete. The discharge end shall be closed at the start of work so as to prevent water entering the tube and shall 'be entirely sealed at all times. The tremie tube shall be kept full 800-12 Section 800 Concrete to the bottom of the hopper:When a batch is dumped into the hopper, the flow of concrete shall be induced^'by `slightly'' raising the discharge end, always keeping it in the deposited concrete. The flow shall be continuous until the work is completed. Depositing of concrete by the drop bottom bucket methodshall conform to the following specification. The top of the bucket shall be open. the bottom door shall open freely and outward when tripping.. The bucket shall be completely filled and slowly lowered to avoid backwash. It shall not be dumped until it rests on the surface upon which the concrete is to be deposited and when discharged, shall be withdrawn slowly until well above the concrete. The slump of concrete shall be maintained between 4 and 8 inches. Unwatering may proceed when the concrete seal is sufficiently hard and strong. All laitance or other unsatisfactory materials shall be removed from the exposed surface by scraping, chipping or other means which will not injure the surface of the concrete. 800-J. CONSTRUCTION JOINTS. ' 1. General. Construction joints shall .b made only where located on Plans or shown in the pouring schedule, unless otherwise approved by the • Engineer. - 1 If not detailed on the Plans, or in the case of emergency, construction joints shall be placed as directed by the Engineer. Shear keys or ' inclined reinforcement shall be used where necessary to transmit shear or bond the two sections together. 2. Bonding. Before depositing new concrete on or against concrete which has ' hardened, the forms shall be retightened. The surface of the hardened concrete shall be roughened as required by the Engineer in a manner that will not leave loosened particles or aggregates or damaged concrete at ' the surface. It. shall be thoroughly cleaned of foreign matter and laitance, and saturated with water. To ensure an excess of mortar at the juncture of the hardened and the newly deposited concrete, the cleaned ' and saturated surfaces, including vertical and inclined surfaces, shall first be thoroughly covered with a coating of mortar or neat cement grout against which the new concrete shall be placed before thegrout has attained its initial set. ' The. placing of concrete shall be carried continuously from joint to joint. The face edges of all joints which are exposed to view shall be ' carefully finished true to line and elevation. 800-K. •FALSEWORK AND CENTERING. Unless otherwise provided, detailed Plans ' for falsework or centering shall be supplied to the Engineer on request; but, in no case shall the Contractor be relieved of responsibility for results obtained by the use of. these Plans. ' For designing falsework and centering, a weight of 150 pounds per cubic foot shall be assumed for green concrete. All falsework shall be designed and constructed to provide the necessary •rigidity and to support the loads without 1 . 800-13 .., VV - - .. VVV Concrete appreciable settlement or deformation. The Engineer may require the Contractor to employ screw jacks or hardwood wedges to take up any settlement in the formwork either before or during the placing of concrete. Falsework which cannot be founded on a satisfactory footing shall be supported on piling which shall be spaced, driven and removed in a manner approved by the Engineer. Falsework shall be set to give the finished structure the camber specified or indicated on the Plans. Arch centering shall be constructed according to centering plans approved by the Engineer. Provision shall be made by means of suitable wedges, sand boxes or other devices for the gradual lowering of centers, and rendering the arch self-supporting. When directed, centering shall be placed upon approved jacks in order to take up and correct any slight settlement which may occur after the placing has begun. 800-L. FOUNDATION PITS AND FORMS. All foundation pits and forms shall be inspected and approved by the Engineer prior to placing any part of the structure and the methods employed in performing the work and all equipment, tools and machinery used for handling materials and executing any part of the work shall be subject to the approval of the Engineer. All equipment, tools and machinery used must be maintained in a satisfactory working condition. Forms shall conform to the shape, lines and dimensions of the concrete as called for on the Plans. All plane form surfaces shall be constructed so that the finished concrete surfaces will be true planes, free from waves and irregularities. Lumber used in forms for exposed surfaces shall be straight, dressed to uniform width and thickness and shall be free from loose knots or other defects. Joints in forms shall be horizontal or vertical. 'For unexposed surfaces, undressed lumber may be used. Lumber once used in forms shall have nails withdrawn and surfaces to be in contact with the concrete thoroughly cleaned before being used again. Forms shall be substantial and sufficiently tight to prevent leakage of mortar. They shall be properly braced or tied together in such a manner that they will maintain their original position and shape under the superimposed loads and the fluid pressure of the concrete. If adequate foundations for shores cannot be secured, trussed supports shall be provided. Where required by the Detailed Specifications, concrete shall be poured against waterproofed Douglas fir plywood, or waterproofed tempered hardpressed fiberboard, of a make and quality approved by the Engineer, and installed in strict conformity to the manufacturer's specifications. Forms used for backing up and otherwise supporting form lining shall have a flat surface but need not be tight. At the top of all walls or other surfaces which are to be finished to a true line, the top of the form shall be brought to a true line and grade so that the surface may be finished by means of a float or template resting on the top edge of the form. Forms, on one side of the wall at least, shall not extend over horizontal construction joints. 800-14 Section 800 Concrete Flat steel bars or rods, -,.unless otherwise authorized, shall be used for internal form ties. They stall be provided$ 'with lugs,nuts, cones or other approved devices, which will serve as spreaders or form spacers, and the ties shall have sufficient mechanical strength, stiffness and rigidity to hold the forms in proper position, spacing and alignment. The ties shall be of such design that the body of the tie will remain embedded in the concrete, with the ends of the ties not closer than 1/2 inch from the outer concrete surfaces. The ends of the embedded portion of the tie shall be provided with holes, corrugations, hooks, or other approved type of mortar clinch, and these ends shall be protected from the concrete by means of cone shaped shields of sufficient depth to provide adequate anchorage for the cement mortar plugs which shall be placed in the holes left by these shields. Wire form ties will be permitted only on light and unimportant work and with the approval of the Engineer. They shall not be used through surfaces where discoloration would be objectionable, wire ties, where used, must not be tightened by twisting, but shall be tightened by means of wedges placed outside the forms. No more initial stress is to be placed in the wire tie than is necessary to remove all slack. Shores supporting successive stories shall be placed directly over those below or so designated that the load will be transmitted directly to them. Forms shall be set to line and grade and so constructed and fastened as to provide and maintain true lines. Special care shall be used to prevent bulging. The forms for all walls should be such as to allow continuous pouring from the bottom to the top of the wall. • Unless otherwise specified, suitable moulding or bevel strips shall be placed in the angles of forms to round •or bevel the edges of the concrete. Bevel strips on the exposed corners of beams and girders shall be carried to within ' 1 foot of the face of the beam support. Bevel strips on the exposed corners of columns shall be carried to within 1 foot of their intersection with the edge of a beam or girder of the same width as the column. If the column is ' from 2 to 6 inches wider than the largest beam or girder it supports, the bevel strips shall extend to within 2 inches of the bottom of the girder. If the column is 6 inches or more wider than the largest beam it supports, the bevel strips shall continue to within 1 foot of the bottom of the slab above ' the beam. Bevel.strips on columns shall stop at a point 16 inches above the floor. The ends of all triangle bevel strips which do not extend the full ' length of the corners they occupy shall be cut off on an angle of 45°. Unless otherwise authorized by the Engineer, the inside of forms shall be coated with non -staining paraffin oil, or other approved material, applied before the reinforcement is placed, and all surplus oil removed from the ' surface of the forms by thorough wiping with soft absorbent cloths. Temporary openings shall be placed at the bottom of the column and.wall forms, ' and at other points where necessary to facilitate cleaning and inspection immediately before depositing concrete. ' Forms shall not be disturbed until the concrete has adequately hardened. Shoring shal.l not be removed until the member has acquired sufficient strength to support its weight and the load upon it. Members subject to additional 1 a 800-15 Concrete U loads during construction shall be adequately shored to support both the member and construction loads in such a manner as will protect the member from damage by the loads; this shoring shall not be removed until the member has acquired sufficient strength to support safely its weight and the load upon it. The following table gives the minimum time which shall elapse between the time of placing the concrete and the removal of forms at various average temperatures. Class of Work Walls in Mass Work Thin Walls - 12 inches or less in thickness Columns - if girders are shored Bottom forms of slabs (5 feet or less span) Above 60° 50° to 60° 40° to 50° 1 day 2 days 3 days 4 days Below 40° ' 2 days 5 days Not until tests have been made indicating concrete is set. 4 days 7 days 5 days 10 days 8 days 14 days Bottom forms of beams 14 days 20 days 28 days and girders (less than 14 inch span) If high early strength cement is used these periods may be reduced as directed by the Engineer. When field operations are controlled by beam or cylinder tests, the removal of forms, supports and housing, and the discontinuance of heating and curing may be begun when the concrete is found to have a modulus of rupture of not less than 600 pounds per square inch or a compressive strength of 3,000 pounds per square inch, provided further that in no case shall supports be removed in less than seven days after pouring the concrete. The beams of cylinders shall be cured under conditions which are not more favorable than the most unfavorable conditions for the portions of the concrete which they represent. Form work in buildings should be so designed that the column forms may be removed without in any way disturbing the supports of the beams or girders, in order than any defect in the column may be detected and remedied before any load is placed on the column. Dimensions of all forms shall be carefully checked by the Contractor and the Engineer after they are erected and before the concrete is placed. The Contractor will be held responsible for the accuracy of all construction. 800-16 Section 800 Concrete 800-N. FINISHING CONCRETE. Face forms shall be removed as• soon as practicable in order to facilitate finishing the concrete surfaces. Care shall be taken, to avoid roughening or injuring corners, and to keep all edges sharp. Immediately after the forms are removed, any fins or other projections shall be carefully removed, rough spots in the faces of the walls and any broken corners or edges shall be repaired and all bolt holes shall be plugged and entirely filled with mortar containing one part by volume of cement and• two parts by volume of sand screened over 'a No. 8 screen.. Pointing shall be brought smooth with the surface by means of a wooden float. A steel trowel shall not be used to finish the surface. Plastering will not be permitted. All concrete which, upon removal of the forms, is found to be porous or "honeycombed" shall be immediately cut out and removed entirely from the body of the concrete. The parts removed shall extend not less than 1 inch back of the reinforcement steel where such steel is present in the concrete face which is being repaired, removing sound concrete, if necessary, to obtain this depth. If reinforcement steel is not present, the parts removed shall extend into the concrete not less than 3 inches and the opening dovetailed in such a manner that the new concrete filling will be securely anchored. In replacing concrete so removed, forms shall be built with a spout or hopper outside the' concrete surface, which shall be filled with fresh concrete to a point not less than 12 inches above the top of the hole caused by removing the porous concrete. ' The fresh concrete shall be properly bonded to the old concrete surfaces, 'as hereinbefore specified, and shall be well puddled. The hopper shall be removed after the concrete has hardened and within 24 hours after the concrete is placed, the excess concrete carefully cut away, and the surface pointed and 'rubbed smooth. Concrete used in replacing porous concrete shall be protected from premature drying as hereinafter specified. After the pointing has set' sufficiently to permit it, all exposed surfaces ' shall be thoroughly wetted and: rubbed with a medium carborundum stone followed by a.second.rubbing with a fine carborundum stone to obtain an entire surface of, a smooth texture and uniformity in color. A cement wash or plaster coat shall not be used. If honeycombing is determined to be excessive by the Engineer, the Contractor shall remove and replace such at his own expense. ' Specific exceptions to rubbing of exposed concrete may be made in the Detailed Specifications or on the Plans. I Particular attention is called to the fact that the tops of all walls shall be finished true to line and grade and shall be troweled smooth. ' Floors, sidewalks, and other exposed wearing surfaces which require finishing shall be poured against carefully set screeds and troweled smooth with power operated trowels. 1 800-17 ■ VGV VLV\. VwV Concrete Excess water shall be drained away or otherwise removed. The final finish with a steel trowel shall not be made until the cement has acquired its initial set. No more troweling shall be done than is necessary to obtain a smooth surface. At the option of the Engineer, the top surfaces of walks may be finished with a light broom or brush and an edging tool instead of a trowel. Sidewalks shall be laid out in blocks with an approved grooving tool as shown on the Plans or as directed by the Engineer. Care must be taken to avoid drawing an excess of cement to the surface of floors or walks. Dry cement or a dry mixture of cement and sand shall not be sprinkled directly on the surface. Floors shall be marked at the direction of the Engineer. Care shall be taken that all floor surfaces drain properly and that the grooving tool does not raise the surface of the floor and form pockets which do not drain. Floors requiring a mortar wearing coat will be so indicated on the Plans and shall be finished as specified. 800-N. CONCRETING IN COLD WEATHER. No concrete shall be placed when the air temperature is below 35° F., unless provision is made for heating the ingredients and for enclosing the concrete and heating the enclosures. No concrete shall be placed when the weather reports indicate air temperatures below 32° F. during the succeeding five days unless provision is made for enclosing the concrete and heating the enclosure. When concrete is placed at air temperature below 35° F., the ingredients shall be heated so that the temperature of the concrete when placed shall be not less than 60° F. The concrete shall be enclosed immediately after placing and the concrete and air in the enclosure kept above 50° F. for a period of five days. When dry heat is used, means of maintaining atmospheric moisture shall be provided. If wet steam is used for heating, the time may be reduced to a minimum of 48 hours provided that the temperature of the concrete and the air in the enclosure is held above 78° F. If protected in this manner, the concrete shall be covered with cotton mats or three thicknesses of 9 ounce burlap after the enclosure is removed and the covering shall remain in place for a total period of five days after placing the concrete. 800-0. CURING CONCRETE FOR STRUCTURES. Membrane curing compound solution shall not be used on surfaces to be rubbed or painted. These surfaces shall be cured with cotton mats or burlap blankets, as provided for below.

The concrete inside the forms shall be sealed immediately "after the forms are removed and necessary finishing has been done. The solution shall.be applied in one or two separate applications. If the solution is applied in two increments, the second applicatdon shall follow the first application in 30 minutes. The Contractor shall provide satisfactory equipment and means to properly control and assure the direct application of the curing solution on the concrete surface so as to result in a. uniform coverage at the rate of one gallon for each 200. square feet of area. If rain falls on the newly coated concrete before the film has dried sufficiently to resist damage or if the film is damaged in any other manner, a new coat of the solution shall be applied to the affected portions equal in curing value to that above specified.. When curing with cotton mats or burlap blankets is required, the exposed concrete immediately after finishing shall be covered with wet cotton mats or two thicknesses of wet burlap blankets. The cotton mats or burlap blankets shall be kept continuously and thoroughly wet for a period of not less than five days after the concrete was placed. 800-P. EXPANSION AND FIXED JOINTS.

Cleanup PIPELINE •� 'AyM.va �y'4Y.�'• . CLEANUP 900-A. GENERAL. Cleanup shall, be considered an important part of this project, and adequate equipment and qualified personnel shall be applied to this phase of the work from the very beginning of the project. There are generally four classifications •of cleanup to be used on this project, as set out below. Class I Cleanup. Areas of construction within lawns, gardens, or other well -kept areas, including street rights of way that are kept as lawns by adjacent landowners. Class II Cleanup. . Areas of construction within fields, meadows and street rights of way which are mowed or cultivated (gardens excepted). Class III Cleanup. Areas of construction that are heavily brushed or wooded, steep rocky slopes,, or other areas where it is not practical for the area to be cultivated. .Special Cleanup. Unless otherwise noted under Section 900-B.4,of these Specifications, no special cleanup will be required. ■ 900-B. METHOD OF CLEANUP. The method of cleanup for each of the classes defined in Section 900-A of these Specifications shall be as set out below. ' 1. Class I Cleanup - Lawns, Gardens, Etc. The trench shall be backfilled in accordance with the pipe specifications. After the topsoil has been ' spread over the damaged areas, the Contractor shall proceed immediately to hand rake the entire construction area to remove all rock 1 inch or larger in diameter. Debris of every type shall be removed and at]. damaged tree limbs shall be pruned. After the area has been raked and. I. accepted by the Engineer, the area shall be seeded at the rate of 0.15 pounds per 100 square feet, using the following seed mixture (percent expressed in terms of weight). ' Lawn Fescue 30% Blue Grass 30% Rye Grass.(Annual) 30% ' White Clover (Common) 10% During or after seeding is complete, all areas shall be covered with ' 10-20-10 fertilizerat the rate of 500 pounds per acre, or approximately one pound per 100 square feet. No watering will be required. ' Straw mulch consisting of good grade clean straw, free of weeds or seed. and of a quality approved by the Engineer prior to use, shall be placed over seeded areas and shall be uniformly spread so as to provide a thickness of approximately 2 inches when first spread. I. Where the existing ground cover does not contain any of the grasses as set out in the seed mixture above (Bermuda grass, Zoysia, etc.), the 1 • 900-1 aecl.ivn wv P. Cleanup Contractor shall be responsible for cutting, removing and stockpiling the existing sod on the job site. After constructing the sewer line, reconnecting the existing service lines, and backfilling the trench, the sod shall be replaced to a condition equal to or better than that prior to construction. In the event that insufficient sod has been stored, or sod has been lost or destroyed, the Contractor shall be responsible for providing and installing new ground cover of the existing type to complete the cleanup. 2. Class II Cleanup - Fields, Meadows, Etc. The trench shall be backfilled in accordance with the pipe specifications. After the backfill is completed and the surface over the trench left slightly rounded, the area shall be machine raked to remove all rock 1 inch or larger in diameter from the finished surface. All excess excavated material shall be removed from the site, including hand raking excess material which has accumulated around fence posts, trees, mailboxes, etc. All areas which have been disturbed, such as that caused by equipment tracks, shall be carefully backfilled and repaired as though it were a part of the actual trench excavation. Seeding and fertilizing of these areas is required using the same mixture and rates as set out for Class I cleanup. 3. Class III Cleanup - Steep, Wooded or Rocky Areas. The trench shall be backfilled in accordance with the pipe specifications. After the trench backfill is complete, all damaged brush of every type shall be cut just below ground surface and all damaged limbs shall be trimmed. All brush and debris shall be disposed of by the Contractor and the entire area shall be machine raked to remove all rock from the finished surface which is 2 inches or larger in diameter. When directed by the Engineer, the area of the trench line shall then be seeded at the rate of 0.15 pounds per 100 square feet using the same seed mixture as set out under Class I cleanup, except that tall fescue (Kentucky 31) shall be used in place of lawn fescue. 4. Special Cleanup. No special cleanup will be required on this project. 5. All Areas. All work within the construction area shall be cleaned up to the satisfaction of the Owner and the Engineer. In general, all rocks, trash, or rubbish of any nature shall be removed from the site of the work. During construction, the Contractor shall at all times keep work areas in a clean, neat and workmanlike condition. Excess pipe, excavation, brush and materials of construction shall be removed and disposed of as the work progresses. In built-up areas, including lawns, the job site shall be cleaned up immediately behind construction. Streets and driveways blocked by excess materials after basic construction is completed will not be tolerated. If the trench should settle while the Contractor is still on the job or within one year of the project completion date, the Contractor shall make the required repairs at no additional cost to the Owner in accordance with the continuing responsibility provisions of these Specifications. 900-2 JCCLSVll JVV P. Cleanup 6. Payment. There is uo_ special pay item for, cleanup.
