E. F. G. H. I. J. If any defective pipe is discovered after it has been installed, it shall be removed and replaced with a sound pipe in a satisfactory manner at no additional cost to the Agency. All pipe and fittings shall be thoroughly cleaned before installation, shall be kept clean until they are used in the work and when laid, shall conform to the lines and grades required. PVC pipe and fittings shall be installed in accordance with requirements of the manufacturer, or as otherwise provided herein. As soon as the excavation is complete to normal grade of the bottom of the trench, bedding shall be placed, compacted and graded to provide firm, uniform and continuous support for the pipe. Bell holes shall be excavated so that only the barrel of the pipe bears upon the bedding. The pipe shall be laid accurately to the lines and grades indicated on the Drawings. Blocking under the pipe will not be permitted. Bedding shall be placed evenly on each side of the pipe to middiameter and hand tools shall be used to force the bedding under the haunches of the pipe and into the bell holes to give firm continuous support for the pipe. Bedding shall then be placed to 12-in above the top of the pipe. The initial 34 of backfill above the bedding shall be placed in 1 -ft layers and carefully compacted. Generally the compaction shall be done evenly on each side of the pipe and compaction equipment shall not be operated directly over the pipe until sufficient backfill has been placed to ensure that such compaction equipment will not have a damaging effect on the pipe. Equipment used in compacting the initial 3-ft of backfill shall be approved by the pipe manufacturer's representative prior to use. All piping shall be sound and clean before installation. When installation is not in progress, including lunchtime, the open ends of the pipe shall be closed by watertight plug or other approved means. Good alignment shall be preserved during installation. The deflection at joints shall not exceed that recommended by manufacturer. Fittings, in addition to those shown on the Drawings, shall be provided, if required, in crossing utilities that may be encountered upon opening the trench. When cutting pipe is required, the cutting shall be done by machine, leaving a smooth cut at right angles to the axis of the pipe. Cut ends of pipe to be used with a bell shall be beveled to conform to the manufactured spigot end. The Engineer or Agency's representative may examine each bell and spigot end to determine whether any preformed joint has been damaged prior to installation. Any pipe having defective joint surfaces shall be rejected, marked as such and immediately removed from the job site. Each length of the pipe shall have the assembly mark aligned with the pipe previously laid and held securely until enough backfill has been placed to hold the pipe in place. Joints shall not be "pulled" or "cramped". Before any joint is made, the pipe shall be checked to assure that a close joint with the next adjoining pipe has been maintained and that the inverts are matched and conform to the required grade. The pipe shall not be driven down to grade by striking it. Precautions shall be taken to prevent flotation of the pipe in the trench. When moveable trench bracing such as moveable sheeting, shoring or plates are used to support the sides of the trench, care shall be taken in placing and moving or supporting bracing to prevent movement of the pipe, or disturbance of the pipe bedding and the backfill. As moveable sheeting, shoring or plates are moved, pipe bedding shall be placed to fill any voids created and the backfill shall be recompacted to provide uniform side support for the pipe.

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. Maximum Time 45 minutes 60 minutes 90 minutes 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. 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. 4. The maximum time intervaI between the addition of mixing water and/or cement to the batch and the placing of concrete in the forms shall not exceed the values shown in Table 2. I Table 2 I If an approved high-range water-reducer (plasticizer) is used to produce plasticized concrete, the maximum time interval shall not exceed 90 minutes. 3.03 INSPECTION AND COORDINATION A. The batching, mixing, transporting, placing and curing of concrete shall be subject to the inspection of the Engineer at all times. The Contractor shall advise the Engineer of hisher 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 reinforcing and the alignment, cleanliness and tightness of formwork. No placement shall be made without the inspection and acceptance of the Engineer. B. The Contractor is responsible to coordinate the requirements of the electrical, mechanical, instrumentation, WAC, architectural, structural, and other Drawings prior to placement of concrete. Anchor bolts, frames, and all embedded items shall be installed prior to placement of the concrete. 3.04 CONCRETE APPEARANCE A. 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 shalI be obtained only by adjusting one or more of the following: 1. The gradation of aggregate. 2. 3. The proportion of fine and coarse aggregate. The percentage of entrained air, within the allowable limits. Cast-in-Place Concrete 03300-1 0 Cannon Road Lift Station Project No. 3583 PCity of Carlsbad-16827W0679-LiH StationV Proj Oocsi7.2 Final Oocs\100 % Specs\O3300 doc B. Concrete for the work shall provide a homogeneous structure which, when hardened, will have the required strength, durability and appearance. Mixtures and workmanship shall be such that concrete surfaces, when exposed, will require no finishing. When concrete surfaces are stripped, the concrete, when viewed in good lighting from 10-ft away, shall be pleasing in appearance, and at 204 shall show no visible defects. 3.05 PLACING AND COMPACTING A. Placing 1. Placing of all concrete shall be in accordance with the recommendations contained in ACI 304R. Use a tremie system for all underwater concrete placement in compliance with ACI 304 R. 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. Confirm that reinforcement and other embedded items are securely in place. Have a competent worker at the location of the placement. The worker shall be able to assure that reinforcing steel and embedded items remain in designated locations while concrete is being placed. 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 that the concrete is being 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 by the Engmeer. 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 comer. Each batch shall be placed into the edge of the previously placed concrete to avoid stone pockets and segregation.

If there is a delay in casting, the concrete placed aRer 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 joink. 8. Formed Concrete a. Place concrete in forms using tremie tubes 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 4ft and the maximum free fall of concrete shall not exceed 44. 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 comers 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. All concrete shall be placed and compacted with mechanical vibrators. One vibrator shall be used for each 8 c.y. placed per hour. The 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. \ 2. 3. A minimum frequency of 7000 rpm is required for mechanical vibrators. Insert vibrators and withdraw vibrators vertically at points from 18 to 30-in apart. At each insertion, vibrate sufficiently to consolidate concrete, generally from 5 to 15 seconds. Do not segregate concrete through over vibration. Keep a spare vibrator on the site during concrete placing operations. 4. Concrete Slabs: Concrete for slabs less than 8-in thck 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.

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. c. d. Surface appears liquefied, flattened and glistening. Trapped air ceases to rise. Coarse aggregate has blended into surface, but has not disappeared. 3.06 CURING AND PROTECTION A. Protect all concrete work against injury from the elements and defacements of any nature during construction operations. 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. Begm 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: 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.

Formed Surfaces: None if nonabsorbent forms are left in place 7 days. Water cure if absorbent forms are used. Sheet cured or liquid membrane cured 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. C. Finished surfaces and slabs shall be protected from the direct rays of the sun to prevent checking and crazing. D. Cold Weather Concreting: 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. The Contractor shall 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 (e.g.: 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 takmg 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/sq ftkr). Cast-in-Place Concrete 03300-1 4 Cannon Road Lift Station Project No. 3583 P:\City of CarIsbad-16827U0679-Lifl Stabon\7 Prq Docs\7.2 Final Docs\lOO % Specsi03300.doc 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. Forms for Beams and slabs Walls and vertical surfaces 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. Degree Days 500 100 b. All necessary precautions shall be taken to promptly deliver, to promptly place the concrete upon its arrival at the job and to provide vibration immediately after placement. c. The Engineer may require the Contractor to immediately cover plastic concrete with sheet material. 3. The Contractor shall 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. 3.07 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, 3 days after concrete placement, nor before reaching the following number of day-degrees of curing (whichever is the longer): 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. 3.08 INSPECTION AND FIELD TESTING A. The batching, mixing, transporting, placing and curing of concrete shall be subject to the inspection of the Engineer at all times. The Contractor shall advise the Engineer of hisher 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 reinforcing steel and the alignment, cleanliness and tightness of formwork. No placement shall be made without the inspection and acceptance of the Engineer. Cannon Road Lift Station Project No. 3583 P:\Cily of Cafisbad-l6B27\3067%Lifl Station\7 Pro) Doa\7.2 Final Docs\IOO % Specs\03300.doc Cast-in-Place Concrete 03300-1 5 B. Sets of field control cylinder specimens will be taken by the Agency's inspector during the progress of the work, in compliance with ASTM C3 1. 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 %et'' 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. Compressive strength tests shall comply with ASTM C39. 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 by the Contractor to achieve the required strengths. C. The Contractor shall cooperate in the making of tests by allowing free access to the work for the selection of samples, providing an insulated and closed, wood or metal curing box for specimens, affording protection to the specimens against injury or loss through the Contractor's operations and fkmish material and labor required for the purpose of taking concrete cylinder samples. All shipping of specimens will be paid for by the Agency. Curing boxes shall be acceptable to the Engineer. D. Slump tests will be made in the field by the Agency immediately prior to placing the concrete. Such tests shall be made in accordance with ASTM C143. Slump test shall be taken for each set of test cylinders defined above. If the slump is greater the specified range, the concrete shall be rejected. E. Air Content: Test for air content shall be made on fresh concrete samples. Air content for concrete made of ordinary aggregates having low absorption shall be made in compliance with either the pressure method complyng with ASTM C23 1 or by the volumetric method complying with ASTM C173. If lightweight aggregates or aggregates with high absorptions are used, the latter test method shall 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. The Contractor shall 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. The Contractor shall repair all core holes per the Engineer's direction. The work of cutting and testing the cores will be at the expense of the Agency and may not be done by the Contractor.

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 andor 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 andor 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 strength, the Engmeer, 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. 3.10 PATCHING AND REPAIRS A. It is the intent of this Section to require quality work including adequate forming, proper mixture and placement of concrete and curing so completed concrete surfaces will require no patching. B. Defective concrete and honeycombed areas as determined by the Engineer shall be chipped off and repaired per Engineer's satisfaction. Use proper bonding agent or epoxy concrete for repair. C. As soon as the forms have been stripped and the concrete surfaces exposed, fins and other projections shall be removed; recesses left by the removal of form ties shall be filled; and surface defects which do not impair structural strength shall be repaired. Clean all exposed concrete surfaces and adjoining work stained by leakage of concrete. D. Immediately after removal of forms remove plugs and break off metal ties as required by Section 03 100. Promptly fill holes upon stripping as follows: Moisten the hole with water, followed by a 111 6-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 oust 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.

Services of Manufacturer's Representative 1. The Contractor shall make available at no extra cost to the the Agency, upon 72 hours notification, the services of a qualified field representative of the manufacturer of curing compound to instruct the user on the proper application of the product under prevailing job conditions. PART 2 PRODUCTS 2.01 MATERIALS (NOT USED) PART 3 EXECUTION 3.01 FORMED SURFACES A. Forms shall not be removed before the requirements of Section 03300 have been satisfied. B. Exercise care to prevent damaging edges or obliterating the lines of chamfers, rustications or comers when removing the forms or performing any other work adjacent thereto. C. D. Rough-Form Finish Clean all exposed concrete surfaces and adjoining work stained by leakage of concrete. 1. Immediately after stripping forms and before concrete has changed color, carefully remove all fins and projections. 2. Promptly fill holes left by tie cones and defects as specified in Section 03300. E. Rubbed Finish Immediately upon stripping forms and before concrete has changed color, carefully remove all fins. While the wall is still damp, apply a thin coat of medium consistency neat cement slurry by means of bristle brushes to provide a bonding coat within all pits, air holes or blemishes in the parent concrete. Avoid coating large areas with the slurry at one time. Before the slurry has dried or changed color, apply a dry (almost crumbly) grout proportioned by volume and consisting of 1 part cement to 1-1/2 parts of clean masonry sand having a fineness modulus of approximately 2.3 and complyng 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. Concrete Finishing 03350-2 Cannon Road Lift Station Project No. 3583 P:\City of Car15bad-l6827\30679~Lifl SLation\7 Proj Docs\7.2 Final Docs\100 46 Specs\03350.doc 3. Allow the mortar to partially harden for 1 or 2 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 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 3 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 cementhand shake in the proportion of two sacks of portland cement to 350-lbs of coarse natural concrete sand shall be sprinkled evenly over the surface at the rate of approximately 500-lbs /1,000 sq ft of floor. Do not sprinkle neat, dry cement on the surface. b. The application of the cementkand 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. 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-lb compaction force distributed over a 2441-1 diameter disc. c. Start floating along walls and around columns and then move systematically across the surface leaving a matte finish.

The compacting machine shall be the "Kelly Power Float with Compaction Control" as manufactured by Kelly Industries of SSP Construction Equipment, Inc., Pomona, CAY 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 will not be permitted. The use of any floating or troweling machine which has a water attachment for wetting the concrete surface during finishing will not be permitted. 2. Hand Floating a. In lieu of power floating, small areas may be compacted by hand floating. The dry cementhand 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 the Drawings. While the concrete is still green, but sufficiently hardened to support a finisher and kneeboards with no more than %-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-ft 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 Engmeer . B . Broom Finish 1. Finish concrete as specified in paragraph 3.02A1 .a. When the concrete has stiffened sufficiently to maintain small surface indentations, draw a 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 Trowel Finish 1. Finish concrete 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. 3.03 APPROVAL OF FINISHES A. All concrete surfaces, when finished, will be inspected by the Engmeer. B. Surfaces which do not meet the requirements in this Section shall be refinished 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 Engmeer.

General 1. Walls shall be fully grouted unless otherwise indicated on the Drawings. 2. Prior to grouting, the grout space shall be clean and free of mortar projections greater than 1/2- in, mortar droppings, or other foreign materials. 3. Reinforcement shall be in place and adequately supported before commencing grouting operations. Reinforcement shall be clean and free of mortar droppings or other debris. Notify the Engineer at least 24 hours prior to any grouting operations so that reinforcement placement, support, and laps may be observed before grouting. Accurately set embedded bolts with templates and hold in place to prevent movement. Provide minimum 1 -in grout space between any bolt and an adjacent masonry surface. 4. Control grout materials and water content during grouting to provide adequate fluidity for placement without segregation. Place grout within 1-1/2 hours after the introduction of water into the mix and prior to initial set. 5. Place grout in a continuous pour to its maximum placement height using lifts of 5-ft or less, and consolidating the grout after each lift. 6. Consolidate grout by mechanical vibration before loss of plasticity, in a manner which will solidly fill the grout space and minimize voids due to absorption of water into the masonry. Reconsolidate grout by mechanical vibration after initial water loss and settlement has occurred. Consolidation should normally occur when the plasticity of the grout approaches that of stiff mortar (when a touch leaves an indentation). 7. Complete grouting of beams over openings in one continuous operation. 8. Use extreme care to prevent any grout or mortar from staining the face of masonry to be left exposed or unpainted. If any grout or mortar does contact the face of such masonry, it shall be removed immediately. Protect all sills, ledges offsets, etc. from grout droppings.

Limitations on grout type (fine or coarse), and height of grout pours shall be as shown in Table 2. Units may be laid to the maximum height of the grout pour before grouting unless otherwise noted on the Drawings or specified. Where this table or notes on the Drawing indicate that walls are to be grouted at intervals less than their final height, use "low-lift" grouting procedures. Where walls are grouted to their final height in one pour, use "high-lift" grouting procedures. Grout Pour Max.

Between grout pours in vertical cells, form a horizontal construction joint "key" in walls by stopping all wythes at the same elevation, and stopping the grout lift a minimum of 1-1/2-in below the mortar joint, except at the top of a wall. Consolidate the grout and then continue the pour. For horizontal bond beams, grout cells below the bond beam and consolidate, then grout the bond beam itself stopping the grout pour 1/2-in below the top of the masonry. At the finished course of both walls and bond beams, bring the last pour flush with the top of the masonry during initial placing and again after consolidation.

Do not erect masonry to a height of more than 80 times the minimum clear cell or grout space dimension nor higher than 30-ft before grouting unless approval is obtained in writing from the Engineer. 2. Where grout pours exceed 5-ft in height, provide clean-outs in the bottom course of masonry. Clean-out openings shall be not less than 12-in2 in area and the least dimension of any opening shall not be less than 3-in. In solid grouted masonry, space clean-outs at each vertical bar, but not more than 32-in on center. 3. Before grouting, clean cells and collar joints and close and seal clean-out openings. Brace closures to resist grout pressure. Pour grout at a rate which will minimize the potential for "blowouts" at the closed clean-out openings, but rapidly enough to allow consolidation before loss of plasticity.
