Placing 1. Verify that alI formwork completely eneloses concrete to be placed and is securelybraced prior to cancrete placement. Rernove ice, excess vvatar, dirt and other foreig� materials from �azms ax�d exposed concrete j oints. Confirm that reinforcernent and other ennbedded items are securely � in place. Have a competent worltman at th� location of the placement who can assure tk�at reinforcement and embedded items remain in designated locations while concrete is being placed. Sprinkje semi porous subgrades ar%rms ta eli�ninate suctian of water from the nnix. `' SeaI extremely porous subgrades in an approved manner. 2. Deposit concrete as near its final positinn as possihle ta a�oid segregation due to rehandling or flav�+ing. Place concrete continuously at a rate which ensures the concrete is being integrated with fresh plastic concrete. Do zaat deposit concrete which has partially hardened or has b�en contaminafed by foreign materials or on conczete which has harciened sufficiently to cause formation of seams or planes af wealrness within the section. If the section cannot be placed continuously, place construction joints as speciiied or as approved. Pumpin� of concrete will be permitted. Use a mix design and aggregate sizes suitable for pumging and subxnit for approval. 4. Remove temporary spreaders from forms wk�en tbe spreader is no langer us�ful. Temporary spreaders may remain exnbedded in conc7rete vnly when rnade of galvaniz�d metal or concrete and if prior approval has been obtained. 5. Do not place concrete far supported elenaents un�il concrete previausly placed in the supporting element (coSumns, slabs and/or walls} has reached adequate strength. 6. Where surface martar is ta £orm �he base of a finish, especially surfaces designated to be painted, work coarse aggregate back from forms with a suitable tool to bring the full suriace of tlae mortar against the form. Pre�vent the formaiion of excessive surface voids. 7. Slabs a. After suitable bulklaeads, screeds and j ointing materials have been positianed, the concrete shall be placed continuously between canstruction joints bep nning at a bulkhead, edgeform, or corner. Each bafch shall be placed into fihe edge of the previously placed concrete to avaid stone pockets and segregation. b. Avoid delays in casting. I.f there is a delay in casting, the conerete placed after the delay shall be thoroughly spaded and consolidated at the edge of that previously placed to avoid cold jaints. Concrete shall then be brought ta correct le�el and struck off with a strazghtedge. Bullfloats or darbies shall be used ta smooth the surface, leaving it free of humps or hailows. c. Where slabs axe to be placed integxally with the vvalls below them, place the walls and consalidate as specified. Allow one hour ta pass between placement of the wall and the F03360.doc 03 3 00-11 i�� iro � CityofFort Warth Rolling Hills W'I'P Backwash Supply System overlying slab to permii consalidation of the wall concrete. Keep the top surface of the wall moist so as to prevent cold joints. Formed Cancrete a. Place concrete in forms using tremie tubes and taldng care to prevent segiregatian. BoEtom of tremie tubes shall preferably be in contact with the cancrete a�eady placed. Do not pertnit concrete to drop freely more #han 4-ft. PIace concrete for waIIs in i 2-in to 24-in lifts, keeping the surface horizontal. If plasticized concrete is used, the maxinnum lift �hickness may be increased to seven feet and the maxirnum free fali of concrete sha�l not exceed 15-ft. B. Consalidating Consolidate concrete by vibration, puddling, spading, radding or forldng so that cancrete is thoroughly warked around reinforcement, embedded items and apenings and into carners of forms. Puddling, spading, etc shall i�e continuousl� perfarmed alang with vibratzon of the placement to eliminate air or stone pockeis which n�aay cause honeycomUing, patting or plazies af weakness. All cancrete sha11 be plaoed and consolidated with rnechanical vibrators, The number, type and siza of the units sl�alI be approved Uy the Engineer in advance of placing operations. No concrete shall be ordered until sufficient appraved vibxators (including standby units in working arder) are on the jab. A rninimum frequency of 7p00 revolutions per minute is required far zx�echanical vibrators. Insert �ibrators and withdraw at poin.ts frnm 18 to 3�-in apart. At each insertion, vibrate �ufficiently ta consolidate concreie, generally from 5 to I 5 seconds. Do not over vibrate so as to segregate. Keep a spare vibrator on the site during con.crete placing operatians. �. Concr�te Slabs: Concxete far slabs less than 8-in thick shall be consolidated �wif.h vibrating sareeds; slabs 8-in to 12-in thick shall be compacted with internal vibrators az�d (np�iona�Iy) with vibrating screeds. Vibrators shall always be placed into conerete vertically and shall not be laid horizontally or iaid over. 5. Walls and Columns: Tnternal vibrators (rather than form vibrators} shall be used unless otherwise appraved Uy th� Engineer. In general, for each �ibrator need�d ta melt dawn the batch at the poznt of discharge, one or more additional vibrators must be used to densify, k�omagenize and perfect the suriace. The �ibrators sha1l be inserted vertically at r�gular intervals, through the fresh concrete and slightly into the pre�ious li�'t, if any. b. Amount of Vibration: Vibrators are to be used to consoIidate properly placed concrete but shall not be used to move or transport concr�te in the farr�ts. Vibration shall continue untiI: a. Frequency re�urns to normal. h. Surface appears liquefed, flattened and glistening. c. Trapped air ceases to rise. d. Coarse aggregate has blended inio surface, but has not disappeared.

Solidly fill cells b�lo�v bearing plates, ]ivatels, and other similar %atures. Place graut in a continuous pour to its max.imum placement height using lifts oi 5 feei ar less, and consolidating the grout after each lift. Consolidate grout Uy mechanical vibratian before ioss of plasticity, in a manner which wi11 solidly �11 #he grout space and minimize voi.ds due to absorption af water into the masonry, Reconsalidate grout by mechanical vibration after initial water loss and set�lement has occurred. Cansolidation should nozxnally occur when the plasticiiy of the grout ap�roaches that of stiff mortar (when. a touch leaves an indentatian). 8. Complete grouting of beams o�er apenings in one continuous aperatinn. Frovide approved rnaterial to confuie the grout in a beam where grou�ing occurs over ungrouted cells below. Material used for oanf nement shall not inhibit Uond between maso�-}+ units and mortar. 9. Use extreme care to prevent any grout ar mortar from staining the face of masonry to be lefi expased or unpainted. If any grout or rnortar does not contact the face of such masonry, it sha11 be removed immediately. Protect alI sills, ledges offsets, etc. from grout drappings. 10. 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 maxixnum height af the grout pour Uefore grouting unless otherwise nated on the Drawings or specified. Where this table ar notes on the Drawing indicate �-iat walls are to be grouted at intervals less than their final height, use "low-lii�" grouting procedures.

B. The �est pressures and temperatures for the various pipe Iines shall. be 15 Q psi at ambient temperature, ;, C. The test shali Ue perfarnled by slowly filling the piping system, exp�lling entrapped air from all high points. The iill rate sha11 be conirolled so that the fluid velocity within th� pipe systern is less than two ,. fps. Upon eompletion of the filling process, the system shali be braught up to the speci�ed test temperature as applicable, holding the system pressure ta less tlnan ten percent oF �he test pressure. �� Once the systena has been stabilized at the specified tesi temperature, the pipe should be slowly brought up to the test pressure in such a nr►anner so as to not create shocic, surge or water harnmer in � the pipe system. Tk�e test duration time limit shall not begin until ihe fizll pressuxe specified above has been reached and the system has been stabilized to witlain five percent of the test texx�perature. The system pressure and ternperature shall be maintained to with.in one-balf percent but no rnore tY�an �ve percent of the specified value for tbe temperature and wiihin five psi af the specified value for the pxessure. These tolerances shall be held far the entire duration of the test. Upon completion af the � test, the pressure shall be slowly rerno�ved by ope�aing a valve or other pressure xelie�ing de�ice at a location remote to the locatian of the pressurelternperature monitoring equipment. D. The gressure test shall be monitored 6y a recording iypa pressure gage for tests not requiring temperature control ax a dual pen pressure/temperature recording gage when temperature control is required. The entire test process shall be recorded, including the initial temperature stabilization and pre�surization of the paping system. The record shall be cantinuous through the system test and shall show th.e final de pressu�ization of the pipe systern. E. All visible leaks detected du�.ng the pressure test shall be repaired and the pressureltemperature test rerun. A successful test shall be a test in which no �isible leaks are detected and the pipe system pressure can be maiz�tained within one-h.alf percent but no more than fi�ve psi af the specified value. F.
