CS-8 19 AIR POLLUTION WATCH DAYS: Add the following to Section C7-7: C7-7.18 AIR POLLUTION WATCH DAYS: The Contractor shall be required to observe the following guidelines relating to working on City construction sites on days designated as "AIR POLLUTION WATCH DAYS". Typically, the OZONE SEASON, within the Metroplex area, runs from May 1, through OCTOBER 31, with 6:00 a.m. - 10:00 a.m. being critical BECAUSE EMISSIONS FROM THIS TIME PERIOD HAVE ENOUGH TIME TO BAKE IN THE HOT ATMOSPHERE THAT LEADS TO EARLY AFTERNOON OZONE FORMATION. . The Texas Commission on Environmental Quality (TCEQ), in coordination with the _ National Weather Service, will issue the Air Pollution Watch by 3:00 p.m. on the afternoon prior to the WATCH day. On designated Air Pollution Watch Days, the Contractor shall bear the responsibility of being aware that such days have been designated Air Pollution Watch Days and as such shall not begin work until 10:00 a.m. whenever construction phasing requires the use of motorized equipment for periods in excess of 1 hour. However, the Contractor may begin work prior to 10:00 Imp a.m. if use of motorized equipment is less than 1 hour, or if equipment is new and certified by EPA as "Low Emitting", or equipment burns Ultra Low Sulfur Diesel (ULSD), diesel emulsions, or alternative fuels such as CNG. If the Contractor is unable to perform continuous work for a period of at least seven hours between the hours of 7:00 a.m. - 6:00 p.m., on a designated Air Pollution Watch Day, that day will be considered as a weather day and added onto the allowable weather days of a given month. 20 C8-8.4 SCOPE OF PAYMENT: Delete C8-8.4 SCOPE OF PAYMENT in its entirety and replace with the following: "The Contractor shall receive and accept the compensation as herein provided, in full payment for furnishing all labor, tools, materials, and incidentals for performing all work contemplated and embraced under these Contract Documents, for all loss and damage arising out of the nature of the work or from the action of the elements, for any unforeseen defects or obstructions which may arise or be encountered during the prosecution which may arise or be encountered during the prosecution of the work at any time before its final acceptance by the Owner, (except as provided in paragraph C5-5.14) for all risks of whatever description connected with the prosecution of the work, for all expenses incurred by or in consequence of the suspension or discontinuance of such prosecution of the working operations as herein specified, or any and all infringements of patents, trademarks, copyrights, or other legal reservations, and for completing the work in an acceptable manner according to the terms of the Contract Documents. = The payment of any current or partial estimate prior to the final acceptance of the work by the Owner shall in no way constitute an acknowledgment of the acceptance of the work, materials, or equipment, nor in any way prejudice or affect the obligations of the Contractor to repair, correct, renew, or replace at his own and CS-9 proper expense any defects or imperfections in the construction or in the strength or quality of the material used or equipment or machinery furnished in or about the construction of the work under contract and its appurtenances, or any damage due or attributed to such defects, which defects, imperfections, or damage shall have been discovered on or before the final inspection and acceptance of the work or during the two (2) year guaranty period after the final acceptance. The Owner shall be the sole judge of such defects, imperfections, or damage, and the Contractor shall be liable to the Owner for failure to correct the same as provided herein." 21. PARTIAL PAYMENTS: Change Paragraph C8-8.5 to read as follows: — "Partial pay estimates shall be submitted by the Contractor 5th day and the 20th day of the month that work has been is in progress. The estimate shall be processed by the — City on the loth day and 25th day respectively. Estimates will be paid within 25 days following the end of the estimate period, less the appropriate retainage as set out below. Partial pay estimates may include acceptable nonperishable materials delivered to the work place which are to be incorporated into the work as a permanent part thereof, but which at the time of pay estimate have not been so installed. If such materials are included within a pay estimate, payment shall be based upon 85% of the net invoice value thereof. The Contractor will furnish the engineer such information as may be reasonably requested to aid in the verification or the preparation of the pay estimate. — For contracts of less than $400,000.00 at the execution, retainage shall be ten percent (10%). For contracts of$400,000.00 or more at the time of execution, retainage shall be five percent(5%). Contractor shall pay subcontractors in accord with subcontract agreement, within five (5) business days after receipt by the Contractor of the payment by the City. Contractor's failure to make the required payment to subcontractors will authorize the — City to withhold future payments from the Contractor until compliance with this paragraph is accomplished. It is understood that the partial pay estimates will be approximate only, and all partial pay estimates and payment of the same will be subject to correction in the estimate rendered following the discovery of an error in any previous estimate. Payment of any — partial pay estimate shall not, in any respect, be taken as an admission of the Owner of the amount of work done or of its quality of sufficiency, or as an acceptance of the work done or the release of the Contractor of any of his responsibilities under the Contract Documents. The City reserves the right to withhold the payment of any partial estimate if the — Contractor fails to perform the work in strict accordance with the specifications or other provisions of this Contract." 22.

No substitutions will be permitted until the Contractor has received written permission of the Engineer to make a substitution for the material which has ■ been specified. Where the term "or equal,"or" or approved equal' is used, it is understood that if a material, product, or piece of equipment bearing the name so used is furnished it will be approvable, as the particular trade name was used for the purpose of establishing a standard of quality acceptable to the City. If a product of any other name is proposed for use, the Engineer's approval thereof must be obtained before the proposed substitute is procured by the Contractor. Where the term "or equal," or"or approved equal' is not used in the specifications, this does not ■ SC-6 ■ PART D - SPECIAL CONDITIONS necessarily exclude alternative items or material or equipment which may accomplish the intended purpose. However, the Contractor shall have the full responsibility of proving that the proposed substitution is, in fact, equal, and the Engineer, as the representative of the City, shall ■ be the sole judge of the acceptability of substitutions. The provisions of this sub-section as related to "Substitutions" shall be applicable to all sections of these specifications. D-14 CONCRETE DRAINAGE CHANNEL/ CURB AND GUTTER REPLACEMENT At locations in the project where mains are required to be placed under the existing drainage ■ channel, the channel shall be completely replaced for the full existing width with 3000# concrete and reinforcing steel on a sand cushion as shown on the plan detail. At locations where the mains are required to be placed under existing curb and gutter, such curb and gutter shall be replaced to match type and geometry of the removed curb and gutter and shall be installed in accordance with City of Fort Worth Public Works Department Standard Specification for Construction, Item 502.

' 3. DEFINITIONS: r A. TRENCHES: A trench is referred to as a narrow excavation made below the surface of the ground in which the depth is greater than the width, where the width measured at the bottom is not greater than fifteen (15) feet. If forms or other structures are installed or constructed in an excavation so as to reduce the dimension measured from the forms or structure to the side of the excavation to fifteen (15) feet or less at the bottom of the excavation, the excavation is also considered to be a trench. B. BENCHING SYSTEM: Benching means excavating the sides of a trench to form one or a series of horizontal levels or steps, usually with vertical or near-vertical surfaces between levels. C. SLOPING SYSTEM: Sloping means excavating to form sides of a trench that are inclined away from the excavation. D. SHIELD SYSTEM: Shields used in trenches are generally referred to as "trench r boxes" or "trench shields." Shield means a structure that is able to withstand the forces imposed on it by a cave-in and protect workers within the structure. Shields can be permanent structures or can be designed to be portable and move along as the work progresses. Shields can be either premanufactured or job-built in accordance with OSHA standards. E. SHORING SYSTEM: Shoring means a structure such as a metal hydraulic, mechanical or timber system that supports the sides of a trench and which is designed to prevent cave-ins. Shoring systems are generally comprised of crossbraces, vertical rails (uprights), horizontal rails (wales) and/or sheeting. ' 4. MEASUREMENT: Trench depth is the vertical measurement from the top of the existing ground to the bottom of the pipe or structures. The quantity of trench safety systems ' shall be based on the linear foot amount of trench depth greater than five (5) feet. 5. PAYMENT: Separate payment will be made only when trench excavations exceed a • depth of five (5) feet and shall be full compensation for safety system design, labor, tools, materials, equipment and incidentals necessary for the installation and removal of l trench safety systems.

Air testing may be used in lieu of an exfiltration test subject to approval of the Engineer. 01445—Pipeline Testing and Cleaning 01445-1 April 2006 City of Fort Worth Walsh Ranch Water Facilities—Phase I _ Ground Storage Reservoir 2230-40761 B. Exfiltration Test _ l. Leakage tests by exfiltration shall be made by creating a head in the pipeline to be tested by filling the line and either a manhole or temporary riser on one end of the line with water. _ The length of pipe to be tested shall be such that the head over the crown at the upstream end is not less than 2-ft and the head over the downstream crown is not more than 6-ft. The pipe shall be plugged by pneumatic bags or mechanical plugs in such a manner that the air can be released from the pipe while it is being filled with water. Before any measurements are made,the pipe shall be kept full of water long enough to allow absorption and the escape of any trapped air to take place. Following this, a test period of at least one hour shall begin. Provisions shall be made for measuring the amount of water required to maintain the water at a constant level during the test period. 2. If any joint shows an appreciable amount of leakage,the jointing material shall be removed and the joint repaired. If any pipe is defective, it shall be removed and replaced. If the quantity of water required to maintain a constant head in the pipe does not exceed 1.9 gallons per inch of diameter per day per 100-ft of pipe and if all the leakage is not confined to a few joints, workmanship shall be considered satisfactory. C. Infiltration Test l. Pipe shall be tested for infiltration after the backfill has been placed and the ground water allowed to return to normal elevation. The length of line to be tested shall be not less than the length between adjacent manholes and not more than the total length of each size of pipe. The allowable infiltration shall be 1.9 gallons per inch of diameter per day per 100-ft of pipe in each section tested. There shall be no gushing or spurting leaks. 2. If an inspection of the completed pipeline or any part thereof shows pipes or joints which allow noticeable infiltration of water,the defective work or material shall be replaced or repaired as directed. 3. Rates of infiltration shall be determined by means of V-notch weirs, pipe spigots, or by plugs in the end of the pipe installed in an approved manner and at such times and locations as may be directed by the Engineer. D. When the pipeline to be tested is reinforced concrete pipe, the allowable leakage in the above tests shall be 4.7 gallons per inch of diameter per 100-ft of pipe. E. Low Pressure Air Test .� 1. Low-pressure air tests shall be made with equipment specifically designed and manufactured for the purpose of testing pipelines using low-pressure air. The equipment shall be provided _ with an air regulator valve or air safety valve so set that the internal air pressure in the pipeline cannot exceed 8 psig. Pneumatic plugs shall have a sealing length equal to or greater than the diameter of the pipe to be tested. All air used shall pass through a single control panel. 2. Install plugs at manholes. Brace plugs securely as required for safety and allow no one in the manholes while pressurizing the line or during the test. 01445—Pipeline Testing and Cleaning 01445-2 April 2006 City of Fort Worth Walsh Ranch Water Facilities—Phase I Ground Storage Reservoir 223040761 3. Low-pressure air shall be introduced into the sealed line until the internal air pressure reaches 4 psig. The internal air pressure in the sealed line shall not be allowed to exceed 8 psig. At least 2 minutes shall be allowed for the air pressure to stabilize in the section under test. After the stabilization period, the low-pressure air supply hose shall be quickly disconnected from the control panel. The time required in minutes for the pressure in the section under test to decrease from 3.5 to 2.5 psig shall not be less than that shown in Table 1 of ASTM C828. 4. If the pipe section does not pass the air test, sectionalize the section tested to determine the location of the leak. Once the leak has been located,repair and retest. 3.04 TESTING PRESSURE PIPELINES A. All pressure pipelines shall be pressure and leakage tested. Pipelines shall be subjected to a hydrostatic pressure of 50 percent above the normal operating pressure and this pressure maintained for at least 10 minutes. The operating pressure for this project is 150 psi. The _ leakage test shall be conducted at the maximum operating pressure as determined by the Engineer, and this pressure shall be maintained for at least two hours. The test pump and water supply shall be arranged to allow accurate measurement of the water required to maintain the test pressure. Where applicable,hydrant branch gate valves shall remain open during this test. The amount of leakage which will be permitted shall be in accordance with AWWA C600. 3.05 CHLORINATION OF PIPELINES A. Before being placed in service, all new potable water pipelines shall be chlorinated using the method specified in AWWA C651-Disinfecting Water Mains and Section 01656. The cleaning procedure shall be approved by the Engineer in advance. B. The location of the chlorination and sampling points will be determined by the Engineer in the - field. Taps for chlorination and sampling shall be installed. Uncover and backfill the taps as required. -r C. The general procedure for chlorination shall be first to flush all dirty or discolored water from the lines and then introduce chlorine in approved dosages through a tap at one end,while water is being withdrawn at the other end of the line. The chlorine solution shall remain in the pipeline for 24 hours. D. Following the chlorination period, all treated water shall be flushed from the lines at their w extremities and replaced with potable water. All treated water flushed from the lines shall be dechlorinated and disposed of by discharging to the nearest sanitary sewer or by other approved means. The method of dechlorination and disposal shall be approved in writing by the Engineer in advance. Bacteriological sampling and analysis of the replacement water may then be made by the Engineer in full accordance with AWWA C651. Rechlorinate, if necessary and the line shall not be placed in service until the requirements of the Texas Commission on Environmental Quality are met. E. Special disinfecting procedures shall be used in connections to existing pipelines and where the method outlined above is not practical.

Trench excavation shall include material of every description and of whatever substance encountered,except rock and boulders. Pavement shall be cut with a saw,wheel or pneumatic chisel along straight lines before excavating. B. Strip and stockpile topsoil from grassed areas crossed by trenches. At the Contractor's option, ! topsoil may be otherwise disposed of and replaced, when required,with approved topsoil of equal quality. C. While excavating and backfilling is in progress,traffic shall be maintained,and all utilities and other property protected as provided in the General Conditions and General Requirements. D. Trenches shall be excavated to the depth indicated on the Drawings and in widths sufficient for laying the pipe, bracing and for pumping and drainage facilities. The bottom of the excavations shall be firm and dry and in all respects acceptable to the Engineer. Trench width shall be practical minimum. E. Excavation and dewatering shall be accomplished by methods which preserve the undisturbed state of subgrade soils. The trench may be excavated by machinery to, or just below the designated subgrade, provided that material remaining in the bottom of the trench is no more than slightly disturbed. Subgrade soils which become soft, loose, "quick", or otherwise unsatisfactory as a result of inadequate excavation,dewatering or other construction methods shall be removed and replaced by screened gravel fill as required by the Engineer at the Contractor's expense. F. Clay and organic silt soils are particularly susceptible to disturbance due to construction operations. When excavation is to end in such soils,use a smooth-edge bucket to excavate the last 1-ft of depth. G. Where pipe is to be laid in screened gravel bedding,the trench may be excavated by machinery to the normal depth of the pipe provided that the material remaining in the bottom of the trench is no more than slightly disturbed. H. Where pipe is to be laid directly on the trench bottom, final excavation at the bottom of the trench shall be performed manually,providing a flat-bottom true to grade upon undisturbed material. Bell holes shall be made as required. 3.02 DISPOSAL OF MATERIALS A. Excavated material shall be stacked without excessive surcharge on the trench bank or obstructing free access to hydrants and gate valves. Inconvenience to traffic and abutters shall be - avoided as much as possible. Excavated material shall be segregated for use in backfilling as specified below. B. It is expressly understood that no excavated material shall be removed from the site of the work or disposed of, except as directed by the Engineer and in accordance with Item D-54 of Part D— Special Conditions. When removal of surplus materials has been approved by the Engineer, dispose of such surplus material in approved designated areas. 02221—Trenching Bacldillingand Compaction.doc 02221-2 April 2006 v City of Fort Worth Walsh Ranch Water Facilities—Phase I Ground Storage Reservoir 2230.40761 C. Should conditions make it impracticable or unsafe to stack material adjacent to the trench, the material shall be hauled and stored at a location provided. When required, it shall be re-handled and used in backfilling the trench. 3.03 SHEETING AND BRACING A. Furnish, put in place and maintain sheeting and bracing required by Federal, State or local safety requirements to support the sides of the excavation and prevent loss of ground which could endanger personnel, damage or delay the work or endanger adjacent structures. If the Engineer is of the opinion that at any point sufficient or proper supports have not been provided,he/she may order additional supports placed at the expense of the Contractor. Compliance with such order shall not relieve the Contractor from his/her responsibility for the sufficiency of such supports. Care shall be taken to prevent voids outside of the sheeting,but if voids are formed,they shall be immediately filled and rammed. B. Where sheeting and bracing is required to support the sides of trenches, engage a professional engineer,registered in the State of Texas,to design the sheeting and bracing. The sheeting and _ bracing installed shall be in conformity with the design and certification of this shall be provided by the professional engineer. Submit P.E. Certification Form contained at the end of this section to show compliance with this requirement. C. When moveable trench bracing such as trench boxes,moveable sheeting, shoring or plates are used to support the sides of the trench, care shall be taken in placing and moving the boxes or supporting bracing to prevent movement of the pipe,or disturbance of the pipe bedding and the screened gravel backfill. 1. When installing rigid pipe(R.C.,V.C.,A.C.,etc),any portion of the box extending below mid diameter shall be raised above this point prior to moving the box ahead to install the next pipe. This is to prevent the separation of installed pipe joints due to movement of the box. 2. When installing flexible pipe(PVC,etc),trench boxes,moveable sheeting,shoring or plates shall not be allowed to extend below mid-diameter of the pipe. As trench boxes,moveable - sheeting, shoring or plates are moved, screened gravel shall be placed to fill any voids created and the screened gravel and backfill shall be recompacted to provide uniform side support for the pipe. D. Permission will be given to use steel sheeting in lieu of wood sheeting for the entire job wherever the use of sheeting is necessary. The cost for use of sheeting will be included in the bid items for pipe and shall include full compensation for driving, bracing and later removal of sheeting. E. All sheeting and bracing shall be carefully removed in such manner as not to endanger the construction of other structures,utilities,or property,whether public or private. All voids left after withdrawal of sheeting shall be immediately refilled with sand by ramming with tools especially adapted to that purpose, by watering or otherwise as directed. - F. No payment will be given for sheeting,bracing, etc, during the progress of the work. No payment will be given for sheeting which has actually been left in the trench for the convenience of the Contractor. 4 02221—Trenching,Backfilling and Compaction.doc 02221-3 April 2006 City of Fort Worth Walsh Ranch Water Facilities—Phase I Ground Storage Reservoir 2230-40761 G. Sheeting driven below mid-diameter of any pipe shall remain in place from the driven elevation to at least 1-ft above the top of the pipe. 3.04 TEST PITS A. Excavation of test pits may be required for the purpose of locating underground utilities or T structures as an aid in establishing the precise location of new work. B. Test pits shall be backfilled as soon as the desired information has been obtained. The backfilled surface shall be maintained in a satisfactory condition for travel until resurfaced as specified. 3.05 EXCAVATION BELOW GRADE AND REFILL A. Whatever the nature of unstable material encountered or the groundwater conditions,trench drainage shall be complete and effective.B. If the Contractor excavates below grade through error or for the Contractor's own convenience,or through failure to properly dewater the trench,or disturbs the subgrade before dewatering is sufficiently complete,he may be directed by the Engineer to excavate below grade as set forth in the following paragraph,in which case the work of excavating below grade and furnishing and placing the refill shall be performed at his own expense. .. C. If the material at the level of trench bottom consists of fine sand, sand and silt or soft earth which may work into the screened gravel notwithstanding effective drainage,the subgrade material shall be removed to the extent directed and the excavation refilled with a 6-in layer of coarse sand,or a mixture graded from coarse sand to the fine peastone,as approved by the Engineer,to form a filter layer preserving the voids in the gravel bed of the pipe. The composition and gradation of gravel shall be approved by the Engineer prior to placement. Screened gravel shall then be placed in 6-in layers thoroughly compacted up to the normal grade of the pipe. If directed by the Engineer,bank-run gravel shall be used for refill of excavation below grade. D. Geotextile filter fabric may be substituted for filter layer if approved by the Engineer. Filter fabric shall be Mirafi 140N; Supac equivalent, or equal. 3.06 BACKFILLING A. As soon as practicable after the pipe has been laid and jointed, backfilling shall begin and -- thereafter be prosecuted expeditiously. Bedding gravel, as specified for the type of pipe installed, shall be placed up to 1-ft over the pipe. B. An impervious dam or bulkhead cutoff of clay or other impervious material shall be constructed in the trench as directed,to interrupt the unnatural flow of groundwater after construction is completed. The dam shall be effectively keyed into the trench bottom and sidewalls. Provide at least one clay or other impervious material dam in the pipe bedding between each manhole where directed or every 300-ft,whichever is less. C. Where the pipes are laid cross-country,the remainder of the trench shall be filled with common fill material in layers not to exceed 3-ft and mounded 6-in above the existing grade or as directed. Where a loam or gravel surface exists prior to cross-country excavations,it shall be removed, conserved and replaced to the full original depth as part of the work under the pipe items. In 02221—Trenching,Backfilling and Compaction.doc 02221-4 April 2006 City of Fort Worth Walsh Ranch Water Facilities—Phase I Ground Storage Reservoir 2230-40761 some areas it may be necessary to remove excess material during the clean-up process, so that the ground may be restored to its original level and condition. D. Where the pipes are laid in streets,the remainder of the trench up to a depth of 1-ft below the bottom of the specified permanent paving shall be backfilled with common fill material in layers not to exceed 1-ft and thoroughly compacted. The subbase layer for paving shall be of bank-run gravel thoroughly compacted in 6-in layers. E. To prevent longitudinal movement of the pipe,dumping backfill material into the trench and then spreading will not be permitted until selected material or screened gravel has been placed and compacted to a level 1-ft over the pipe. F. Backfill shall be brought up evenly on all sides. Each layer of backfill material shall be thoroughly compacted by rolling,tamping,or vibrating with mechanical compacting equipment or hand tamping,to 92 percent compaction. If rolling is employed, it shall be by use of a suitable roller or tractor, being careful to compact the fill throughout the full width of the trench. G. Water jetting or puddling may be used'unless the refill contains too great a proportion of clay or loam to permit satisfactory drying. Water jetting shall consist of using a suitable length of pipe at least 1-1/4-in in diameter fitted with quick acting valve and sufficient hose to connect to hydrant or pump having adequate pressure and capacity. The full depth of backfill shall be thoroughly inundated by thrusting the pipe into the fill at frequent intervals with the valve open until all slumping ceases. Where backfill is compacted by puddling, it shall be done by depositing in water. Water for jetting or puddling may be obtained from Owner hydrants wherever possible. Water may be furnished by the Owner from these hydrants if reasonable care is exercised in its use and when approved by the Water Department. H. If water restrictions are in force, obtain water elsewhere,or compact the backfill by other approved methods at no additional cost to this Contract. I. Where other methods are not practicable,compaction shall be by use of hand or pneumatic ramming with tools weighing at least 20 lbs. The material being spread and compacted in layers not over 6-in thick. If necessary, sprinkling shall be employed in conjunction with rolling or ramming. J. Backfill around structures shall be selected common fill material,may be compacted by puddling where approved by the Engineer. All backfill shall be compacted, especially under and over pipes connected to the structures. K. Subject to the approval of the Engineer,fragments of ledge and boulders smaller than 6-in may be used in trench backfill providing that the quantity in the opinion of the Engineer, is not excessive. Rock fragments shall not be placed until the pipe has at least 2-ft of earth cover. Small stones and rocks shall be placed in thin layers alternating with earth to ensure that all voids are completely filled. Fill shall not be dropped into the trench in a manner to endanger the pipe. L. Bituminous paving shall not be placed in backfilling unless specifically permitted, in which case it shall be broken up as directed. Frozen material shall not be used under any circumstances. M. All road surfaces shall be broomed and hose-cleaned immediately after backfilling. Dust control measures shall be employed at all times. 02221—Trenching,Baclfilling and Compaction.doc 02221-5 April 2006 City of Fort Worth Walsh Ranch Water Facilities—Phase 1 Ground Storage Reservoir v 223040761 3.07 RESTORING TRENCH SURFACE A. Where the trench occurs adjacent to paved streets, in shoulders, sidewalks, or in cross-country areas,thoroughly consolidate the backfill and shall maintain the surface as the work progresses. If settlement takes place, immediately deposit additional fill to restore the level of the ground. B. In and adjacent to streets,the top 12-in of trench backfill shall consist of compacted bank-run gravel. Should the Contractor wish to use material excavated from the trench as gravel subbase for pavement replacement,the Contractor,at his/her own expense,have samples of the material tested by an independent testing laboratory at intervals not to exceed 500-t in order to establish its compliance with the specifications. Only material which has been tested and approved by the Engineer shall be allowed to be incorporated into the work. C. The surface of any driveway or any other area which is disturbed by the trench excavation and which is not a part of the paved road shall be restored to a condition at least equal to that existing before work began. D. In sections where the pipeline passes through grassed areas, and at the Contractor's own expense, remove and replace the sod, or loam and seed the surface to the satisfaction of the Engineer.

PART 3 EXECUTION 3.01 INSTALLATION A. Sediment Fence Installation 1. A 6-inch wide trench is to be cut 6 inches deep at the toe of the fence to allow the fabric to be laid below the surface and backfilled with compacted earth or gravel to prevent bypass of runoff under the fence. Fabric shall overlap at abutting ends a minimum of 3 feet and shall be joined such that no leakage or bypass occurs. 2. Sufficient room for the operation of sediment removal equipment shall be provided between the silt fence and other obstructions in order to properly maintain the fence. 3. The ends of the fence shall be turned upstream to prevent bypass of storm water.Sediment fences shall be positioned as indicated on the Drawings and as necessary to prevent off site movement of sediment produced by construction activities as directed by the Engineer. 4. Dig trench approximately 6-in wide and 6-in deep along proposed fence lines. 5. Drive stakes, 6-ft on center(maximum)at back edge of trenches. Stakes shall be driven 1-ft (minimum)into ground. 6. Hang filter fabric on posts carrying to bottom of trench with about 6-in of fabric laid across bottom of trench. Stretch fabric fairly taut along fence length and maintain secure both ways. 7. Backfill trench with excavated material or rock backfill and tamp. 8. Install pre-fabricated silt fence according to manufacturer's instructions. B. Construct filter boxes as detailed on the Drawings, from 1/4-in woven wire mesh or hardware cloth and wood. Fill with crushed stone and place over all drop inlets and manholes to storm drain system as each inlet is completed. This should be done prior to setting casting, if there is a delay between installation of inlet structures or drain manholes and setting of castings. An alternate method is to ring each inlet with a sediment fence. C. Stone Filter Berm or Rock Check Dam Installation 1. Stone shall be well graded with size range from 1-1/2 to 3-1/2 inches in diameter depending on expected flows. 02270—Erosion and sedimentation Control 02270-3 April 2006 City of Fort Worth Walsh Ranch Water Facilities—Phase I Ground Storage Reservoir 223040761 2. Rock check dams should be triangular in cross section with side slopes of 1:1 or flatter on the upstream side and 2:1 or flatter on the downstream. D. Staging areas and Construction Entrance shall be surfaced with a minimum 12-in thickness of 3 to 5 inch coarse aggregate. 3.02 MAINTENANCE AND INSPECTIONS A. Inspections 1. Make a visual inspection of all erosion and sedimentation control devices once per week and promptly after every rainstorm. If such inspection reveals that additional measures are needed to prevent movement of sediment to offsite areas,promptly install additional devices as needed. Sediment controls in need of maintenance shall be repaired promptly. B. Device Maintenance 1. Sediment Fences a. Remove accumulated sediment once it builds up to 1/2 of the height of the fabric. b. Replace damaged fabric,or patch with a 2-ft minimum overlap. c. Make other repairs as necessary to ensure that the fence is filtering all runoff directed to the fence. 2. Filter Boxes a. Replace crushed stone when it becomes saturated with silt. 3. Stone Filter Berm a. Muck out trapped silt from dewatering operations when it has built up to within 6-in of _ the top of the berm. b. Replace crushed stone filter when saturated with silt. 4. Add crushed stone to access ways and staging area as necessary to maintain a firm surface free of ruts and mudholes. 3.03 TEMPORARY MULCHING A. Straw mulch should be anchored by application of a fiber mulch binder, by the application of a - synthetic liquid mulch binder,by using a tractor-drawn crimper to punch into the soil,or by placing netting above the mulch stapled to the ground, as required. B. Mulch hydraulically applied with tackifiers and binding agents is commercially available as a bonded fiber matrix(BFM)which may be particularly effective on slopes steeper than 2.5:1. 02270—Erosion and Sedimentation Control 02270-4 April 2006 - City of Fort Worth Walsh Ranch Water Facilities—Phase I Ground Storage Reservoir 223040761 C. Wood chips are suitable for areas that will not require mowing frequently and are heavy enough that they do not require anchoring. They do,however,deplete nitrogen from the soil,which is a necessary nutrient for all plants. To alleviate this condition,wood chips must be treated with 12 pounds of ammonium nitrate per ton of mulch used. D. Bark chips are popular for ornamental applications,as they do not require anchoring,do not decompose very rapidly, and serve as an excellent insulation material. When using bark chips, it is not necessary to treat for nitrogen deficiency or to fertilize. E. Compost and wood mulch mixtures should be a blend of 50%untreated wood mulch with 50% compost measured by volume. Wood mulch should be less than or equal to 5 in. in length with 95%passing a 2-in. screen and less than 30%passing a 1-in. screen. The compost shall meet the Physical Requirements specified in Table 1 of TxDOT Special Specification 1058, Compost, which can be found in Appendix F. F. Prior to the placement of any mulch,the area to be protected must be graded in accordance with plans. G. Fertilization and soil treatment should then be done prior to placement of mulch with the exceptions of when seed is to be applied by means of hydro-seed or when seed is distributed following straw mulch spreading during winter months. H. Organic mulches may be distributed by hand or my mechanical means, but to be effective a complete covering is required. 3.04 EROSION CONTROL BLANKETS A. Erosion control blankets shall be installed in all seeded drainage swales and ditches as shown on the Drawings and as directed by the Engineer in accordance with manufacturer's instructions. The area to be covered shall be properly prepared, fertilized and seeded with permanent vegetation before the blanket is applied. When the blanket is unrolled,the netting shall be on top and the fibers in contact with the soil over the entire area. The blankets shall be applied in the direction of water flow and stapled. Blankets shall be placed a minimum of three rows(of 4-ft) wide(total approx. 12-ft width)within the drainage swale/ditch and stapled together in accordance with manufacturer's instructions. Side overlaps shall be 4-in minimum. The staples shall be made of wire, .091-in in diameter or greater, "U" shaped with legs 10-in in length and a — 1-1/2-in crown. Commercial biodegradable stakes may also be used with prior approval by the Engineer. The staples shall be driven vertically into the ground, spaced approximately two linear feet apart,on each side, and one row in the center alternately spaced between each size. Upper — and lower ends of the matting shall be buried to a depth of 4-in in a trench. Erosion stops shall be created every 25-ft by making a fold in the fabric and carrying the fold into a silt trench across the full width of the blanket. The bottom of the fold shall be 4-in below the ground surface. Staple on both sides of fold. Where the matting must be cut or more than one roll length is required in the swale,turn down upper end of downstream roll into a slit trench to a depth of 4-in. Overlap lower end of upstream roll 4-in past edge of downstream roll and staple. 1. To ensure full contact with soil surface, roll matting with a roller weighing 100 lbs/ft of width perpendicular to flow direction after seeding,placing matting and stapling. Thoroughly inspect channel after completion. Correct any areas where matting does not present a smooth surface in full contact with the soil below. 02270—Erosion and Sedimentation Control 02270-5 April 2006 City of Fort Worth Walsh Ranch Water Facilities—Phase I Ground Storage Reservoir �- 2230.40761 3.05 REMOVAL AND FINAL CLEANUP A.

Trial mixtures developed by a testing laboratory, acceptable to the Engineer, engaged by and at the expense of the Contractor. The water content of the concrete mix, determined by laboratory testing, shall be based on a curve showing the relation between water cementitious ratio and 7 and 28 day compressive strengths of concrete made using the proposed materials. The curves shall be determined by four or more points, each representing an average value of at least three test specimens at each age. The curves shall have a range of values sufficient to yield the desired data, including the specified design strengths as modified below,without extrapolation. The water content of the concrete mixes to be used, as determined from the curve, shall correspond to strengths 16 percent greater than the specified design strengths. The resulting mix shall not conflict with the limiting values for maximum water cementitious ratio and net minimum cementitious content as specified in Table 1. D. Compression Tests: Provide testing of the proposed concrete mix or mixes to demonstrate compliance with the specified design strength requirements in conformity with the above paragraph. E. The water soluble chloride ions in concrete shall be not be greater than 0.15 percent when tested in conformity with ASTM C 1218. 03300—Cast-in-Place Concrete 03300-7 April 2006 City of Fort Worth Walsh Ranch Water Facilities—Phase I Ground Storage Reservoir 2230-40761 F. Entrained air, as measured by ASTM C231, shall be as shown in Table 1. I. If the air-entraining agent proposed for use in the mix requires testing methods other than ASTM C231 to accurately determine air content, make special note of this requirement in the admixture submittal. G. Slump of the concrete as measured by ASTM C143, shall be as shown in Table 1. If a high- range water-reducer(plasticizer)is used,the slump indicated shall be that measured before plasticizer is added. Plasticized concrete shall have a slump ranging from 7 to 10-in. H. Where fly ash is included in the mix,the fly ash content shall be no less than 15 percent nor more than 25 percent of the total cement plus pozzolan content,by weight. 'M I. Where Type III cement is approved for use, the concrete shall conform to Table 1 except that the design strength shall be attained at 7 days. J. Proportion admixtures according to the manufacturer's recommendations. Two or more admixtures specified may be used in the same mix provided that the admixtures in combination .. retain full efficiency and have no deleterious effect on the concrete or on the properties of each other.

Concrete for the work shall provide a homogeneous structure which,when hardened,will have the required strength,durability and appearance. It is the intent of these specifications that mixtures and workmanship shall be such that concrete surfaces,when exposed, will not require patching or repairs due to defects. When concrete surfaces are stripped,the concrete, when viewed in good lighting from 10-ft away, shall be pleasing in appearance, and at 20-ft shall show no visible defects. B. Position embedded anchor bolts using templates. C. Unless otherwise shown or approved, conduits and pipes embedded within a slab, wall, or beam (other than those merely passing through) shall satisfy the following: 1. Maximum outside dimension shall be no greater than 1/3 the overall thickness of slab, wall, or beam. 2. Spacing shall be greater than or equal to three diameters or widths on center. D. Ensure that all aluminum embedments are effectively coated or isolated to prevent aluminum- concrete reaction or electrolytic action between aluminum and steel. + 3.02 MEASURING MATERIALS A. Concrete shall be composed of portland cement,pozzolan(where applicable), fine aggregate, coarse aggregate, water and admixtures as specified and shall be produced by a concrete mixing plant conforming to ACI 301 and acceptable to the Engineer. All constituents, including admixtures, shall be batched at the plant except that a high-range water-reducer may also be added in the field. B. Measure materials for batching concrete by weighing in conformity with and within the tolerances given in ASTM C94 except as otherwise specified. Scales shall have been certified by the local Sealer of Weights and Measures within 1 year of use. C. Measure the amount of free water in fine aggregates within 0.3 percent with a moisture meter. Compensate for varying moisture contents of fine aggregates. Record the number of gallons of water as-batched on printed batching tickets. D. Admixtures shall be dispensed either manually using calibrated containers or measuring tanks, or by means of an automatic dispenser approved by the manufacturer of the specific admixture. 1. Charge air-entraining and chemical admixtures into the mixer as a solution using an automatic dispenser or similar metering device. T 2. Inject multiple admixtures separately during the batching sequence. 03300—Cast-in-Place Concrete 03300-9 April 2006 City of Fort Worth Walsh Ranch Water Facilities—Phase I Ground Storage Reservoir _ 2230-40761 3.03 MIXING AND TRANSPORTING A. Concrete shall be ready-mixed concrete produced by equipment acceptable to the Engineer. No hand-mixing will be permitted. Clean each transit mix truck drum and reverse drum rotation before the truck proceeds under the batching plant. Equip each transit-mix truck with a continuous,nonreversible,revolution counter showing the number of revolutions at mixing speeds. B. Ready-mix concrete shall be transported to the site in watertight agitator or mixer trucks loaded not in excess of their rated capacities as stated on the name plate. C. Keep the water tank valve on each transit truck locked at all times. Any addition of water must be directed by the Engineer. Added water shall be incorporated by additional mixing of at least 35 revolutions. All added water shall be metered and the amount of water added shall be shown on each delivery ticket. ! D. All central plant and rolling stock equipment and methods shall comply with ACI 301. E. Select equipment of size and design to ensure continuous flow of concrete at the delivery end. Metal or metal-lined non-aluminum discharge chutes shall be used and shall have slopes not exceeding 1 vertical to 2 horizontal and not less than 1 vertical to 3 horizontal. Chutes more _ than 20-ft long and chutes not meeting slope requirements may be used if concrete is discharged into a hopper before distribution. F. Retempering(mixing with or without additional cement, aggregate, or water)of concrete or mortar which has reached initial set will not be permitted. G. Handle concrete from mixer to placement as quickly as practicable while providing concrete of required quality in the placement area. Dispatch trucks from the batching plant so they arrive at the work site just before the concrete is required,thus avoiding excessive mixing of concrete while waiting or delays in placing successive layers of concrete in the forms. H. Furnish a delivery ticket for ready mixed concrete to the Engineer as each truck arrives. Each ticket shall provide a printed record of the weight of cement and each aggregate as batched - individually. Use the type of indicator that returns for zero punch or returns to zero after a batch is discharged. Clearly indicate the weight of fine and coarse aggregate, cement and water in each batch,the quantity delivered,the time any water is added, and the numerical sequence of _ the delivery. Show the time of day batched and time of discharge from the truck. Indicate the number of revolutions of the truck mixer. I. Temperature and Mixing Time Control 1. In cold weather,do not allow the as-mixed temperature of the concrete and concrete temperatures at the time of placement in the forms to drop below 40 degrees F. 2. If water or aggregate has been heated, combine water with aggregate in the mixer before cement is added. Do not add cement to mixtures of water and aggregate when the temperature of the mixture is greater than 90 degrees F. 03300—Cast-in-Place Concrete 03 3 00-10 April 2006 City of Fort Worth Walsh Ranch Water Facilities—Phase I Ground Storage Reservoir 2230-40761 3. In hot weather, cool ingredients before mixing to maintain temperature of the concrete below the maximum placing temperature of 90 degrees F. If necessary, substitute well-crushed ice for all or part of the mixing water. - 3. The maximum time interval between the addition of mixing water and/or cement to the batch and the placing of concrete in the forms,with concrete continually agitated, shall not exceed the values shown in Table 2. _ 4. TABLE 2 MAXIMUM TIME TO DISCHARGE OF CONCRETE Concrete Temperature Maximum Time 80 to 90 Degree F(27 to 32 Degree C).........................................................................45 minutes 70 to 79 Degree F(21 to 26 Degree C).........................................................................60 minutes 40 to 69 Degree F(5 to 20 Degree C)...........................................................................90 minutes If an approved high-range water-reducer(plasticizer)is used to produce plasticized concrete, the maximum time interval shall be 90 minutes. J. Concrete mix showing either poor cohesion or poor coating of the coarse aggregate with paste shall be remixed. If this does not correct the condition,the concrete shall be rejected. If the slump is within the allowable limit,but excessive bleeding,poor workability, or poor finishability are observed,changes in the concrete mix shall be obtained only by adjusting one -` or more of the following: l. The gradation of aggregate. 2. The proportion of fine and coarse aggregate. - 3. The percentage of entrained air,within the allowable limits. 3.04 PLACING AND COMPACTING A. Placing l. Verify that all formwork completely encloses concrete to be placed and is securely braced prior to concrete placement. Remove ice, excess water,dirt and other foreign materials from forms and exposed concrete joints. Confirm that reinforcement and other embedded items are securely in place. Have a competent workman at the location of the placement who can assure that reinforcing steel and embedded items remain in designated locations while concrete is being placed. Voids in sleeves, inserts,etc., shall be filled temporarily with readily removable material to prevent the entry of concrete. Sprinkle semi-porous = subgrades or forms to eliminate suction of water from the mix. Seal extremely porous subgrades in an approved manner. -- 2. Deposit concrete as near its final position as possible to avoid segregation due to rehandling or flowing. Place concrete continuously at a rate which ensures the concrete is being "' 03300—Cast-in-Place Concrete 03300-11 April2006 City of Fort Worth Walsh Ranch Water Facilities—Phase I Ground Storage Reservoir 2230-40761 integrated with fresh plastic concrete. Do not deposit concrete which has partially hardened or has been contaminated by foreign materials or on concrete which has hardened — sufficiently to cause formation of seams or planes of weakness within the section. If the section cannot be placed continuously,place construction joints as specified or as approved. 3. Pumping of concrete will be permitted. Use a mix design and aggregate sizes suitable for pumping and submit for approval. 4. Remove temporary spreaders from forms when the spreader is no longer useful. Temporary spreaders may remain embedded in concrete only when made of galvanized metal or concrete and if prior approval has been obtained. 5. Do not place concrete for supported elements until concrete previously placed in the supporting element(columns, slabs and/or walls)has reached adequate strength. — 6. Where surface mortar is to form the base of a finish,especially surfaces designated to be painted,work coarse aggregate back from forms with a suitable tool to bring the full — surface of the mortar against the form. Prevent the formation of excessive surface voids. 7. Slabs a. After suitable bulkheads, screeds and jointing materials have been positioned,the concrete shall be placed continuously between construction joints beginning at a bulkhead, edge form, or corner. Each batch shall be placed into the edge of the previously placed concrete to avoid stone pockets and segregation. b. Avoid delays in casting. If there is a delay in casting,the concrete placed after the delay shall be thoroughly spaded and consolidated at the edge of that previously placed to avoid cold joints. Concrete shall then be brought to correct level and struck off with a straightedge. Bullfloats or darbies shall be used to smooth the surface, leaving it free of humps or hollows. c. Where slabs are to be placed integrally with the walls below them,place the walls and compact as specified. Allow 1 hour to pass between placement of the wall and the overlying slab to permit consolidation of the wall concrete. Keep the top surface of the wall moist so as to prevent cold joints. 8. Formed Concrete a. Place concrete in forms using tremie tubes and taking care to prevent segregation. Bottom of tremie tubes shall preferably be in contact with the concrete already placed. Do not permit concrete to drop freely more than 4-ft. Place concrete for walls in 12 to 24-in lifts,keeping the surface horizontal. If plasticized concrete is used,the — maximum lift thickness may be increased to 7-ft and the maximum free fall of concrete shall not exceed 15-ft. b. A minimum of 48 hours shall have elapsed between casting of adjacent wall sections at a vertical construction joint. 03300—Cast-in-Place Concrete 03 3 00-12 April 2006 City of Fort Worth Walsh Ranch Water Facilities—Phase I Ground Storage Reservoir 2230-40761 9. Concrete shall not be placed underwater, unless approved in writing by the Engineer. B. Compacting 1. Consolidate concrete by vibration,puddling, spading,rodding or forking so that concrete is thoroughly worked around reinforcement, embedded items and openings and into corners of forms. Puddling, spading, etc, shall be continuously performed along with vibration of the placement to eliminate air or stone pockets which may cause honeycombing, pitting or planes of weakness. 2. All concrete shall be placed and compacted with mechanical vibrators. The number,type and size of the units shall be approved by the Engineer in advance of placing operations. No concrete shall be ordered until sufficient approved vibrators(including standby units in working order)are on the job. 3. A minimum frequency of 8000 rpm is required for mechanical vibrators. Insert vibrators and withdraw at points from 18 to 30-in apart. At each insertion,vibrate sufficiently to consolidate concrete, generally from 5 to 15 seconds. Do not over vibrate so as to segregate. Keep a spare vibrator on the site during concrete placing operations. 4. Concrete Slabs: Concrete for slabs less than 8-in thick shall be consolidated with vibrating screeds; slabs 8 to 12-in thick shall be compacted with internal vibrators and(optionally) with vibrating screeds. Vibrators shall always be placed into concrete vertically and shall not be laid horizontally or laid over. 5. Walls and Columns: Internal vibrators(rather than form vibrators)shall be used unless otherwise approved by the Engineer. In general,for each vibrator needed to melt down the batch at the point of discharge, one or more additional vibrators must be used to densify, homogenize and perfect the surface. The vibrators shall be inserted vertically at regular intervals,through the fresh concrete and slightly into the previous lift, if any. 6. Amount of Vibration: Vibrators are to be used to consolidate properly placed concrete but shall not be used to move or transport concrete in the forms. Vibration shall continue until: a. Frequency returns to normal. _ b. Surface appears liquefied, flattened and glistening. c. Trapped air ceases to rise. d. Coarse aggregate has blended into surface,but has not disappeared. 3.05 CURING AND PROTECTION A. Protect all concrete work against injury from the elements and defacements of any nature during construction operations. 033 00—Cast-in-Place Concrete 03 3 00-13 April 2006 City of Fort Worth Walsh Ranch Water Facilities—Phase I Ground Storage Reservoir _ 2230-40761 B. Curing Methods 1. Curing Methods for Concrete Surfaces: Cure concrete to retain moisture and maintain specified temperature at the surface for a minimum of 7 days after placement. Curing methods to be used are as follows: _ a. Water Curing: Keep entire concrete surface wet by ponding,continuous sprinkling or covered with saturated burlap. Begin wet cure as soon as concrete attains an initial set and maintain wet cure 24 hours a day. b. Sheet Material Curing: Cover entire surface with sheet material. Securely anchor sheeting to prevent wind and air from lifting the sheeting or entrapping air under the sheet. Place and secure sheet as soon as initial concrete set occurs. c. Liquid Membrane Curing: Apply over the entire concrete surface except for surfaces to receive additional concrete. Curing compound shall NOT be placed on any concrete surface where additional concrete is to be placed,where concrete sealers or surface coatings are to be used, or where the concrete finish requires an integral floor product. Curing compound shall be applied as soon as the free water on the surface has — disappeared and no water sheen is visible,but not after the concrete is dry or when the curing compound can be absorbed into the concrete. Application shall be in compliance with the manufacturer's recommendations. _ 2. Specified applications of curing methods. a. Slabs for Water Containment Structures and Chemical Spill Basins: Water curing only. b. Slabs on Grade and Footings(not used to contain water): Water curing, sheet material curing or liquid membrane curing. c. Structural Slabs(other than water containment): Water curing or liquid membrane curing. d. Horizontal Surfaces which will Receive Additional Concrete,Coatings, Grout or Other Material that Requires Bond to the substrate: Water curing. - e. Formed Surfaces: None if nonabsorbent forms are left in place 7 days. Water cure if absorbent forms are used. Sheet cure or liquid membrane cure if forms are removed prior to 7 days. Exposed horizontal surfaces of formed walls or columns shall be water cured for 7 days or until next placement of concrete is made. f. Concrete Joints: Water cured or sheet material cured. 3. When approved by the Engineer, curing time may be reduced to 3 days for concrete placements using Type III cement. — C. Finished surfaces and slabs shall be protected from the direct rays of the sun to prevent checking and crazing. D. Cold Weather Concreting: 033 00—Cast-in-Place Concrete 03300-14 April2006 = City of Fort Worth Walsh Ranch Water Facilities—Phase I Ground Storage Reservoir 2230-40761 1. "Cold weather" is defined as a period when for more than 3 successive days,the average daily outdoor temperature drops below 40 degrees F. The average daily temperature shall be calculated as the average of the highest and the lowest temperature during the period from midnight to midnight. 2. Cold weather concreting shall conform to ACI 306.1 and the additional requirements specified herein. Temperatures at the concrete placement shall be recorded at 12 hour intervals(minimum). 3. Discuss a cold weather work plan with the Engineer. The discussion shall encompass the _ methods and procedures proposed for use during cold weather including the production, transportation,placement, protection, curing and temperature monitoring of the concrete. The procedures to be implemented upon abrupt changes in weather conditions or equipment failures shall also be discussed. Cold weather concreting shall not begin until the work plan is acceptable to the Engineer. 4. During periods of cold weather,concrete shall be protected to provide continuous warm, moist curing(with supplementary heat when required)for a total of at least 350 degree-days of curing. a. Degree-days are defined as the total number of 24 hour periods multiplied by the weighted average daily air temperature at the surface of the concrete(eg: 5 days at an average 70 degrees F=350 degree-days). b. To calculate the weighted average daily air temperature, sum hourly measurements of the air temperature in the shade at the surface of the concrete taking any measurement less than 50 degrees F as 0 degrees F. Divide the sum thus calculated by 24 to obtain the weighted average temperature for that day. 5. Salt, manure or other chemicals shall not be used for protection. 6. The protection period for concrete being water cured shall not be terminated during cold weather until at least 24 hours after water curing has been terminated. -- E. Hot Weather Concreting 1. "Hot weather" is defined as any combination of high air temperatures, low relative humidity and wind velocity which produces a rate of evaporation estimated in accordance with ACI 305R,approaching or exceeding 0.2 lbs/sqft/hr). 2. Concrete placed during hot weather, shall be batched, delivered,placed, cured and protected in compliance with the recommendations of ACI 305R and the additional requirements specified herein. a. Temperature of concrete being placed shall not exceed 90 degrees F and every effort shall be made to maintain a uniform concrete mix temperature below this level. The temperature of the concrete shall be such that it will cause no difficulties from loss of slump,flash set or cold joints. b. All necessary precautions shall be taken to promptly deliver,to promptly place the concrete upon its arrival at the site and to provide vibration immediately after placement. 03300—Cast-in-Place Concrete 03300-15 April 2006 City of Fort Worth Walsh Ranch Water Facilities—Phase I Ground Storage Reservoir _ 2230-40761 c. The Engineer may direct the Contractor to immediately cover plastic concrete with sheet material. 3. Discuss with the Engineer a work plan describing the methods and procedures proposed to use for concrete placement and curing during hot weather periods. Hot weather concreting _ shall not begin until the work plan is acceptable to the Engineer. F. Do not apply unbalanced loads, such as backfill or hydrostatic pressure, against structural components until the concrete has attained its specified design strength. 3.06 REMOVAL OF FORMS A. Except as otherwise specifically authorized by the Engineer, forms shall not be removed before the concrete has attained a strength of at least 30 percent of its specified design strength, nor before reaching the following number of day-degrees of curing(whichever is the longer): TABLE 3 MINIMUM TIME TO FORM REMOVAL Forms for De erg a Days Beams and slabs 500 Walls and vertical surfaces 100 (See definition of degree-days in Paragraph 3.05D above). B. Shores shall not be removed until the concrete has attained at least 60 percent of its specified design strength and also sufficient strength to support safely its own weight and construction live loads. 3.07 INSPECTION AND FIELD TESTING A. The batching,mixing, transporting,placing and curing of concrete shall be subject to inspection — by the Engineer at all times. The Contractor shall advise the Engineer of his/her readiness to proceed at least 24 hours prior to each concrete placement. The Engineer will inspect the preparations for concreting including the preparation of previously placed concrete,the T reinforcing steel and the alignment, cleanliness and tightness of formwork. No placement shall be made without the inspection and acceptance of the Engineer. B. Sets of field control cylinder specimens will be taken by the Laboratory during the progress of w the work, in compliance with ASTM C31. The number of sets of concrete test cylinders taken of each class of concrete placed each day shall not be less than one set per day,nor less than one set for each 150 cu yds of concrete nor less than one set for each 5,000 sq ft of surface area for slabs or walls. 1. A "set" of test cylinders consists of four cylinders: one to be tested at 7 days and two to be tested and their strengths averaged at 28 days. The fourth may be used for a special test at 3 days or to verify strength after 28 days if 28 day test results are low. 03300—Cast-in-Place Concrete 03300-16 April2006 — City of Fort Worth Walsh Ranch Water Facilities—Phase I Ground Storage Reservoir 2230-40761 2. When the average 28 day compressive strength of the cylinders in any set falls below the - specified design strength or below proportional minimum 7 day strengths(where proper relation between seven and 28 day strengths have been established by tests),proportions, water content, or temperature conditions shall be changed to achieve the required strengths. C. Cooperate in the making of tests by allowing free access to the work for the selection of samples, providing an insulated closed curing box for specimens, affording protection to the specimens against injury or loss through the operations and furnish material and labor required for the purpose of taking concrete cylinder samples. All shipping of specimens will be paid for by the Owner. Curing boxes shall be acceptable to the Engineer. D. Slump tests will be made in the field immediately prior to placing the concrete. Such tests will be made in accordance with ASTM C 143. If the slump is outside the specified range, the concrete will be rejected. E. Air Content: Test for air content will be made on fresh concrete samples. Air content for concrete made of ordinary aggregates having low absorption will be made in compliance with -- either the pressure method complying with ASTM C231 or by the volumetric method complying with ASTM C 173. If lightweight aggregates or aggregates with high absorptions are used,the latter test method will be used. F. The Engineer may have cores taken from any questionable area in the concrete work such as construction joints and other locations as required for determination of concrete quality. The results of tests on such cores shall be the basis for acceptance, rejection or determining the continuation of concrete work. G. Cooperate in obtaining cores by allowing free access to the work and permitting the use of ' ladders, scaffolding and such incidental equipment as may be required. Repair all core holes. The work of cutting and testing the cores will be at the expense of the Owner,unless the concrete fails to meet the required compressive strength. 3.08 FAILURE TO MEET REQUIREMENTS - A. Should the strengths shown by the test specimens made and tested in compliance with the previous provisions fall below the values given in Table 1,the Engineer shall have the right to require changes in proportions outlined to apply to the remainder of the work. Furthermore, the Engineer shall have the right to require additional curing on those portions of the structure represented by the test specimens which failed. The cost of such additional curing shall be at the Contractor's expense. In the event that such additional curing does not give the strength required, as evidenced by core and/or load tests,the Engineer shall have the right to require strengthening or replacement of those portions of the structure which fail to develop the required strength. The cost of all such core borings and/or load tests and any strengthening or concrete replacement required because strengths of test specimens are below that specified, shall be entirely at the expense of the Contractor. In such cases of failure to meet strength requirements the Contractor and Engineer shall confer to determine what adjustment, if any, can be made in compliance with Sections titled "Strength" and "Failure to Meet Strength Requirements" of ASTM C94. The "purchaser" referred to in ASTM C94 is the Contractor in this Section. B. When the tests on control specimens of concrete fall below the specified strength, the Engineer will permit check tests for strengths to be made by means of typical cores drilled from the structure in compliance with ASTM C42 and C39. In the case of cores not indicating adequate 03300—Cast-in-Place Concrete 03300-17 April 2006 City of Fort Worth Walsh Ranch Water Facilities—Phase I Ground Storage Reservoir — 223040761 strength,the Engineer, in addition to other recourses, may require, at the Contractor's expense, load tests on any one of the slabs,beams, piles,caps, and columns in which such concrete was used. Tests need not be made until concrete has aged 60 days. C. Should the strength of test cylinders fall below 60 percent of the required minimum 28 day strength,the concrete shall be rejected and shall be removed and replaced. 3.09 PATCHING AND REPAIRS A. Surface defects which do not impair the structural integrity shall be repaired as approved by the Engineer. Defective concrete and honeycombed areas as determined by the Engineer shall be replaced or repaired using methods specified in Section 03740. B. Immediately after the forms,have been stripped and before the concrete has changed color, carefully remove all fins and projections. Clean all exposed concrete surfaces and adjoining -` work stained by leakage of concrete,to approval of the Engineer. C. Immediately after removal of forms remove plugs and break off metal ties as required by Section 03100. Promptly fill holes as follows: Moisten the hole with water, followed by a 1/16-in brush coat of neat cement slurry mixed to the consistency of a heavy paste. Immediately plug the hole with a 1 to 1.5 mixture of cement and concrete sand mixed slightly damp to the — touch(just short of"balling"). Hammer the grout into the hole until dense, and an excess of paste appears on the surface in the form of a spiderweb. Trowel smooth with heavy pressure. Avoid burnishing. D. When patching defects in exposed surfaces,the same source of cement and sand as used in the parent concrete shall be employed. Adjust color if necessary by addition of proper amounts of white cement. Rub lightly with a fine Carborundum stone at an age of 1 to 5 days if necessary — to bring the surface down with the parent concrete. Exercise care to avoid damaging or staining the virgin skin of the surrounding parent concrete. Wash thoroughly to remove all rubbed matter. 3.10 CONCRETE SCHEDULE A.

Before the slurry has dried or changed color,apply a dry(almost crumbly)grout proportioned by v volume and consisting of one part cement to 1-1/2 parts of clean masonry sand having a fineness modulus of approximately 2.3 and complying with the gradation requirements of ASTM C33 for such a material. Grout shall be uniformly applied by means of damp pads of coarse burlap approximately 6-in square used as a float. Scrub grout into the pits and air holes to provide a dense mortar in all imperfections. 3. Allow the mortar to partially harden for one or two hours depending upon the weather. If the air is hot and dry,keep the wall damp during this period using a fine,fog spray. When the grout has hardened sufficiently so it can be scraped from the surface with the edge of a steel trowel without - damaging the grout in the small pits or holes, cut off all that can be removed with a trowel. (Note: Grout allowed to remain on the wall too long will harden and will be difficult to remove.) 4. Allow the surface to dry thoroughly and rub it vigorously with clean dry burlap to completely remove any dried grout. No visible film of grout shall remain after this rubbing. The entire cleaning operation for any area must be completed the day it is started. Do not leave grout on _ 03350—Concrete Finishes 03350-2 April 2006 City of Fort Worth Walsh Ranch Water Facilities—Phase 1 = Ground Storage Reservoir 2230-40761 surfaces overnight. Allow sufficient time for grout to dry after it has been cutoff with the trowel so it can be wiped off clean with the burlap. 5. On the day following the repair of pits,air holes and blemishes,the walls shall again be wiped off clean with dry,used pieces of burlap containing old hardened mortar which will act as a mild abrasive. After this treatment,there shall be no built-up film remaining on the parent surface. If, however, such a film is present, a fine abrasive stone shall be used to remove all such material without breaking through the surface film of the original concrete. Such scrubbing shall be light and sufficient only to remove excess material without changing the texture of the concrete. 6. A thorough wash-down with stiff bristle brushes shall follow the final bagging or stoning operation. No extraneous materials shall remain on the surface of the wall. The wall shall be sprayed with a fine fog spray periodically to maintain a continually damp condition for at least R three days after the application of the repair grout. 3.02 FLOORS AND SLABS ` A. Floated Finish: 1. Machine Floating a. Screed floors and slabs with straightedges to the established grades shown on the Drawings. Immediately after final screeding,a dry cement/sand shake in the proportion of two sacks of portland cement to 350 pounds of coarse natural concrete sand shall be sprinkled evenly over the surface at the rate of approximately 500 pounds per 1,000 square feet of floor. Do not sprinkle neat,dry cement on the surface. The application of the cement/sand shake may -- be eliminated at the discretion of the Engineer if the base slab concrete exhibits adequate fattiness and homogeneity, and the need is not indicated. b. When the concrete has hardened sufficiently to support the weight of a power float without its digging into or disrupting the level surface,thoroughly float the shake into the surface with a heavy revolving disc type power compacting machine capable of providing a 200 pound compaction force distributed over a 24-in diameter disc. c. Start floating along walls and around columns and then move systematically across the surface leaving a matte finish. d. The compacting machine shall be the "Kelly Power Float with Compaction Control' as manufactured by Kelley Industries of SSP Construction Equipment,Inc.,Pomona,CA,or equal. Troweling machines equipped with float (shoe) blades that are slipped over the trowel blades may be used for floating. Floating with a troweling machine equipped with normal trowel blades shall not be permitted. The use of any floating or troweling machine which has a water attachment for wetting the concrete surface during finishing shall not be permitted. 2. Hand Floating a. In lieu of power floating, small areas may be compacted by hand floating. The dry cement/sand shake previously specified shall be used unless specifically eliminated by the Engineer. Screed the floors and slabs with straightedges to the established grades shown on "" 03350—Concrete Finishes 03350-3 April2006 City of Fort Worth Walsh Ranch Water Facilities—Phase I Ground Storage Reservoir — 2230-40761 the Drawings. While the concrete is still green, but sufficiently hardened to support a finisher and kneeboards with no more than 1/4-in indentation,wood float to a true, even plane with no coarse aggregate visible. Use sufficient pressure on the wood floats to bring moisture to the surface. 3. Finishing Tolerances a. Level floors and slabs to a tolerance of plus or minus 1/8-in when checked with a 10 foot straightedge placed anywhere on the slab in any direction. Where drains occur,pitch floors to drains such that there are no low spots left undrained. Failure to meet either of the above requirements shall be cause for removal, grinding, or other correction as directed by the _ Engineer. B. Broom Finish 1. Screed slabs with straightedges to the established grades indicated on the Drawings and provide a floated finish as specified in Paragraph 3.02A. When the concrete has stiffened sufficiently to maintain small surface indentations, draw a stiff bristle broom lightly across the surface in the direction of drainage,or,in the case of walks and stairs,perpendicular to the direction of traffic, to provide a non-slip surface. C. Steel Troweled Finish 1. Provide a floated finish as specified in Paragraph 3.02A. Then,hand steel trowel to a perfectly smooth,hard,even finish,free from high or low spots or other defects. Provide two trowelings unless additional trowelings are specified. Where a nonslip steel troweled finish is specified, lightly broom the concrete after the final troweling as specified in Paragraph 3.02B. — 3.03 APPROVAL OF FINISHES A. All concrete surfaces,when finished,will be inspected by the Engineer. B. Surfaces which, in the opinion of the Engineer, are unsatisfactory shall be refmished or reworked. C. After finishing horizontal surfaces,regardless of the finishing procedure specified,the concrete shall be cured in compliance with Section 03300 unless otherwise directed by the Engineer. 3.04 SCHEDULE OF FINISHES A.
