GENERAL CONSTRUCTION A; y r r ry { i SECTION 1- GINERAL CONSTRUCTION ITEM 101 - GENERAL REQUIREMENTS A. General: This section of the specifications contains detail specifi- cations and descriptions covering the major items of construction and work- manship necessary for building and completing the various units or elements of the project. The specifications are intended to be so written that only first class workmanship and finish of the best grade and quality will result. Barely meeting the very minimum requirements will not be considered as satis- factory. The fact that these specifications may fall to be so complreto"as to cover all details will not relieve the Contractor of full responsibility for providing a completed project of high quality, first class finish and appear- ance and satisfactory for operation. B. Materials: The specifications for materials set out the minimum standard of quality which the Owner believes necessary to procure a satisfactory pro- ject. 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 Ovner. 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. Wherever the term "or equal" is used it is understood to mean "or approved equal". C. Final Testing and Operation: Prior to presentation for final acceptance of the work under this contract, the Contractor shall have started and operated all units of the plant for a sufficient duration of time to permit the Engineer to observe overall performance and individual performance of the respective units and equipment. Such operation shall be properly coordinated with the Owner's operating personnel. D. Sanitation and Clean Up: During construction, the Contractor shall main- tain the premises in an orderly, neat, and presentable condition. Scraps and debris shall not be left scattered around buy shall be assembled at one place. When construction under the Contract has been otherwise completed, the Con- tractor shall remove all left over construction materials, equipment, scraFs, debris and rubbish, and leave the site in a neat, well kept appearance. To provide good sanitary conditions during construction, the Contractor shall provide adequate sanitary facilities for the workmen, and Contractor shall not permit any unsanitary practices to continue which irould prove ob- jectionable.to surrounding property owners. At the completion of the wort;, all buildings and structures shall be broom clean. He shall clean the walls of all hydraulic structures of dirt, I 101-1 I stains, or other material and pipes shall be left free of any and all foreign material. He shall remove all marks, stains, dirt and soil from all finished surfaces and shall thoroughly clean all flcors, clean and polish all finished hardware and other such devices. E. Disinfection: After completion of the work the Contractor shall disinfect all potable water liner prior to their being placed in service. They shall be filled with chlorinated water in which the residual shall be maintained at not less than SO ppm for 24 hours. The Contractor shall furnish all materials, labor, etc., for disinfecting. END OF ITEM ' 101-2 ITEM 102 --EARTHWORK A. General: The Contractor shall perform all earthwork as may be necessary for the construction, to line and grade shown, of all structures; pipe trenches, roadways, beds, tanks, embankments, etc., and incidentals thereto. All excava- tion shall be "unclassified". The plans show 14gof Teat Borings for general' Information of the bidders. Bidders are expected to ascertain for themselves the character of sub-surface conditions as the lrsformation shown on the-plans Is In no way guaranteed as accurate or complete. I B. Clearing and Grubbinx: Clearing shall consist of the removal of all trees, brush, and rubbish from the entire construction site, except for areas not to be disturbed. Grubbing of roots and stumps will be required to a depth of one foot below the finished grade of structural excavations and to a depth of one foot Wlow the ground surface, after topsoll removal, In areas to receive embankment. All cleared and grubbed mstgrialj shall be properly disposed of.

All seams shall be cleaned out and filled with concrete at the time the footing is placed. Excavated material required to be used for backfill or embankment may be deposited by the Contractor in storage plies at points convenient far rehandling the material during the backfill operatione+. The location of storage piles shall be subject to the approval of the Engineer. C. Pier Drilling: Piers shall rest on type material and be of depth indicated. Boles shall be drilled with equipment designed especially for the purpose. After drilling and belling, all holes shall be thoroughly cleaned of all loose and dis- turbed excavation. Bottoms of holes shall present solid, undisturbed bearing to receive the footing. All footing excavation and loose earth shall be depos- ited at least three feet clear of sides of holes, leaving top of holes level, clean and free of loose earth. Cover the holes with a wood platform until pouring begins. The drilling contractor shall furnish temporary casings, it required at his own expense, to prevent caving of the sides until concrete is poured. D,' Backfill Around Structures: After completion of foundations, wallo, et61, aII'forim' shi11;be relsoved and excavation cleaned of debris or other objection- Wt matter prior wplacing backfill. In areas where structures such as slabs or pipes are to be constructed on backfill, backfill..shell be leah'concrets loeatediee shown on tha'plans and as specified in Item 103, Concrete. The lean concrete shall be carefully vibrated. In certain arose, the lhgineur way elect to roquire the Contraetor~to back- fill with mechanically tamped earth in'lieu of lean'conorste. In these areas, backfill of selected material shall be placed In layers not to exceed 8 inches, loose (higher lifts may be allowed in accordance with manufadturerts eteoamdAd- atione for large mechanical tampers), and water shall be added as nscossary to produce "optimum" moisture conditions for compaction. The layers shall be com- pacted by mechanical tampers to provide not less than ninety eight percent (98%) of maximum density as determined by the American Asso6istion df State Highway Officials Test T99, latent deeignationr Laboratory control will be used to assure compliance with this requirement All other backfill 'around structUras shall be consolidated by the pressure jetting method. Ieyers of backfill may be placed in maximum lifts of 6 feet loose measure. Pressure 'jetting shall continus'in each lift of backfill until that lift is completely saturated. E. Embankmert'ts U, Generals Construction of embankment shall-be with earthen :material, wetted ZT7c pacte'd is'hereiit`specified, to the eleVstions,'lines grades end slopes indicated on the plans. The Contractor shall maintain the drainage of the embankment in s manner satisfactory to the Engineer until final completion 1024 and;accsptance of the work under the contract. Embankment material shall not contain stumps, roots, vegetation, large or frozen lumps, or other extraneous materials. 2. Preparation of Site: Prior to placing any embankment, all clearing, grubbing and stripping operations shall be completed and stump holes or other small excavat,lons shall be backfilled wl;h suitable material and thoroughly tamped. The embankment site shall then be wetted, disced to mix the water thoroughly in the ground surface, and rolled with a sheepsfoot type tamper roller to assure a uniform density of the ground surface and to provide a good bond between the ground surface and the first lfft of embankment. 3. Placing of Material: After the site has been properly prepared, • the placing of embankment material may proceed. Material shall be from borrow sources near the site, to be designated by the Engineer. Care shall be used in the excavation of borrow material so that the compacted embankment wild have the necessary degree of compaction, plasticity index, impermeability, and stability. The s:eiterial shall be,spread In approximately horiggotol layers not morq than eight inches (8") thick before compacting. If, in the opinion of the Ihjineeri:the. surface of the embankment ',a too smooth and bard to bond prop- erly with the succeeding;leyeri such sv*fspe shall be roughened 'iid;Id¢'¢~ecJ; by scarifying before tha sycge9d~ng,1*y~r if pleo~d? Mot 108 b14IRO P, ment shall be so routed over the surface of the embankment to distributo.,tho,a Added compaction afforded by the rolling equipment. e .4.= Process laa,of Material t. After sp;o 4ing ' the m opfkal on Kije 0.91v, bankmenti,xolsture shall;;be added to.provide a total m9lstyre„co9t40t,slightV In excess of that,which,will obtain optiqum unit dry wetghte~of,t4e pa tic4ls,r material! wlrh,the;spegICled,,roll Ing gqulpment;and.nethod;of ;gl,l~n t}e moisture content shall be uniformly distributed throughout the layer of mst•~F- ial, and to accomplish this distribution, the layer of material shall be mixed by discing or harrowing between applications of water. Should the surface of a previously compacted layer become dry due to exposure to the elements, or whether dry or not, if deemed necessary by the Engineer to properly distribute the required amount of moisture, the surface of the compacted layer shall be thoroughly wetted prior to placing the material for the succeeding layer. Should a layer of material be overwetted, such layer shall be allowed to dry to the proper consistency prior to rolling. Should the surface of a layer become hard and smooth, the surface shall be roughened by scarifying and thoroughly wetted prior to placing the material for the succeeding layer. The embankment shall be co.apacted with a sheepsfoot type tamper roller, water and/or sand ballasted, having tamping feet uniformly staggered over ics cylindrical surface, and equipped with cleaners. "amping feet shall be round, diamond or square shaped with a face area not less than five and one-half (A) nor more than ten (10) square Inches. Tamping feet shall project seven (7) to ten (10) inches from the cylindrical surface of the drum. Spacing of tamping Beet shall be such that each two square feet of drum surface will have approximately three tamping feet. Total weight of the roller shall be such that the foot pressure will not be less than three hundred (300) pounds per square inch when empty and not less than five hundred pounds (500) per square inch when ballasted. 102-3 i T' `After addition of water to a spread layer to provide the required moisture content, the layer shall be compacted by rolling with the above specified sheeps- foot type tamper roller. The rollers shall be pulled by a crawler type tractor of adequate power at a speed of two to three miles per hour. Each )ayer shall be compacted by not less than eight (8) passes of the tamper roller, one (1) pass shall constitute the passing of one (1) roller in one (1) direction: over any'given spot. Successive trips of the roller shall overlap not less than two (20) feet. Where new material abuts old material, the old or natural material shall be scarified, wetted, and worked with the rollers along with each layer of new material to provide adequate bond between the materials. It is anticipated that the specified rolling equipment and method of rolling will provide not less than ninety five percent (95%) maximum density of the raterial as determined by American Association of State Highway Officials Test T99, latest designation.

Steal beams or forms and falseworl- for superstructures ahall not be erected on concrete substructures until the concrete in the substructurfe has cured at least four curing days. Concrete for concrete slab cr girder spana of concrete slabs on steel beam opens 4hall not be placed until the substructure has cured at least seven curing days. Steel trusses or plate girders to be erected from the ground on approved falsework may be erected when the substructure has cured four curing days, but the falsework shall not be removed until the substructure has cured at least seven curing days. Forms for walls or columns shall not be erected on concrete, footings until the concrete in the footing has cured at least two curing days. Concrete may be placed in a wall or column as soon as the forms and zeinforcing steel placements are approved. The use of completed portions of a structure as the site for mixing operations or for storage of materials will not be permitted until the particular portion of the structure has aged at ieasc ten curing days. A curing day is defined in, paragraph M, hereof, "Removal of Forms and Falsework", In con- ,j tinued.cold weather, the construction operations may be authorised,at the end of a period of calendar days equal to twice the number of.;uring days specified above.

In order to avoid jamming such forms hy, the expansion action of the concrete and the consequent likelihood of injury to the ad3a:.ant concrete, these forma shall be removed or loosened as soon as prac:ic4b1e after the concrete has attained its final set. A; provision for lxsening the forms to permit free expansion. of the concrete without,, the neces,ait•y f or full removal is preferred. 2 Workmanship: Arta^re¢ joints shall bg.carefully constructed ~n otfles to avoid defective ancho.age of the steel and to avoid porous or honeycombed 1.concreta,4id3acenc to save, premolded materials, wherever used,,shall be anph91:04 io Ghr, c.oac rece, 4n, one side of the joint by means pf on epptoved., adhesive, Suck, anforage.sbpLl be zufficient to preclude, the teodency of „ the material to fall out of the joint. Careful workmanship shall be exercised in the construction of all joints to insure that the concrete sections are completely separated by an open joint, or by the joint materials, 104-3 r 1 and to insure that the joints will be true to the outline indicated. Immediately after the removal of forms, and again where necessary after surface finishing, all projecting concrete shall be removed along the exposed edges of premolded materials in order to secure full effectiveness of the expansion joint. Where roofing felt or premolded materials are specified for horizontal joints, this material shall, if practicable, extend two inches beyond the form for the top member. The projection portions shall be subsequently trimmed to the face of the member after the forme are removed. G. Construction Joints: 1. General Requirements: The joint formed by placing plastic concrete in direct contact with concrete that has attained its initial set shall be deemed a construction joint. When concrete in a structure or a portion of a structure 13 specified to be placed monolithically, the term monolithic shall be interpreted to mean that the manner and sequence of concrete placing shall be such that construction joints will not occur. Construction joints shall be of the type and spacing shown on the Plans. Additional joints will not be permitted without written authorization from the Engineer. Any addi- tional construction joints shall have details equivalent to those s'ro+VM ob the Plan's tot joitits in similar locations. 2. Preparation of Existing Concrete: Before joining plastic concrete to concrete Chat' ab a teady set;'the outface of the concrete in place shall b'e''YeAbooabiy fough with comb aggregate particles exposed; shall be free from all loose materials, laitance, dirt, or foreign matter, shall be washed and scrubbed clean with stiff brooms and thoroughly drenched with water until saturated; ar,d shall be kept wet until the plastic concrete has been placed. The method of concrete shall be determined by the Contractor subject to approval of the Engineer. Immediately prior to the placing of additional concrete on horizontal surfaces, all forms shall be drawn tight against the concrete in place, and the surface of the concrete in place shall be flushed itith'e costing of'tortar about two inches thick. An application of mortar should be applied on vertical surfaces, if possible. This mortar shall be worked into the irregularities of the hard surface if possible, and should have the same sand and cement content and water-cement ratio as the concrete being placed. In lieu of this method of providing excess mortar for coating, the Engineer tiay require that the Contractor provide excess mortar by leaving out orc-half of the gravel in concrete for first layer at the joint. If shown on the Plat$r construction joints shall be provided with concrete keyways, reinforcing 'steel dowels and/or water stops. The method of forming keys for keyed joints shall be such as to permit the easy removal of forms without chipping, breaking, or damaging the concrete in any manner. All keyway forms meat be oiled before installation. Special attention shall'be given to the construction of keyed joints so that they itill be neatly' constructed of thoroughly compacted concrete, free of excessi/kter hnd laitance i3ed uniform in every respect. 104-4 H. Falsework: 1. General. Requirements: All falsework shall be designed and constructed so that no excessive settlement or deformation will occur, and so that the necessary rigidity will be provided. Details of falsework constructed shall be subject to review and approval by the Engineer in accordance with the provisions of Section A. "General Construction Requirements", of this item. 2. Design Loads: For calculating the loads on falsework, a weight of 150 pounds per cubic foot shall be assumed for concrete, and a live load allowance of 50 pounds per square foot of horizontal surface of the form work shall be included. The maximum unit stresses shall not exceed 125 percent of the allowable stresses used by the Engineer for the design of the structures. 3. Materials: All timber used En falsework centering shall be sound, in good condition, and free from deftets which will impair its strength. Steel members shall be of adquate strength and of such shape as to be suitable for the purpose intended.- Timber piling may be of any species; of wood which will withstand driving satisfactorily and which will ads quately support the superimposed load. 4. Workmanship: Where sills or timber grillages are used to support falsework columns, such sills and grillagess unless founded on solid rock,. .flfshble,br other hard materials shall be placed in excavated pits and back filled to prevent the softening of the supporting material by drip from the forms or by rains that may occur during the construction process. Sills or-kt illages shall be of ample si,e to support the superbaposed load without settlement Falsework which cannot be founded on ,a satisfactory spread footing shall be supported on piling which shall, be driven to a , baairing' capacity sufficient to support the su;,arimpused load without - settleAent." In general, each falsework bent shall be capped traasverdily, at the proper' elevation by a cap of adequate size. If desired by the Contractor, howevero a short cap section forming a T-hese may be sub- stituted at the top of each pile or column in the bent and shall be set at the proper elevation to produce, in conjunction with the use of approved hardwood wedges or jacks, permanent camber indicated on the Plans or specified, plus a construction camber covering allowance for de- formation of the forms and falsework. The use of wedges to compensate for incorrectly cut bearing surfaces will not be permitted. Wedges shall be used in pairs and shall be so arranged as to insure uctiform bearing. Each., falsework bent shall be'securely braced to adjacdnt bents by bracing material of ample size to provide the stiffness required.' The bracing shall b6 sectltely spiked or bolted to each' pi It or colurdn it may c'rose: , ' TFormal 1.

If, at any stage of the work, the forms show signs of,bulging or sagging, that portion of the concrete causing such condition shall be immediately removed, if nece=sary, and the forms shall be, reset and securely braced against further movement. Forms or form lumber to be reused shall be maintained clew and in good condition as to accuracy, shepe, strength, rigid- ity, tightness, and smoothness of surface. Any lumber which is Split, warped, bulged, marred, or has defects that may prodves work Inferior to that resulting from using new Werial'ahall not be reused. All forms shall be so constructed as to permit removal without damage to the concrete. Particular and special care must be exercised in framing forms for copings, offsets, railing, and all ornamental work; so that there will be no damage to or marring of the concrete when the forms are removed, If desired by the Contractor, the forms may be given a slight: draft to permit ease of removal. Whenever practicable, forms shall be erected complete before, the reinforcement is placed. For narrov walls and other lbcationb where access to the bottom oU the forma is not otherwise readily attainable, adequate cleanout ope:titigs shall be providedr At;the time of placing concrete, the forms shall be Glean and entirely free from all chips, dirt, sawdust, and other extraneous matter.

Preliminary Consideration: The Contractor shall notify the Engineer upon completion of various portions of the work required for placing concrete so that inspection may be made as early as is practi.able. The Contractor shall also keep the Engineer informed regarding his anticipated concrete placing schedule. When all items have been found to be in order by the Engineer including lines and grades, forms, reinforcing, inserts, piping, electrical, plumbing and the Contractor's concreti:►g paterials'and'equip- ment, the Engineer will then authorize the Contractor 4"'"r1ting to proceed. Concrete placed without such authority will not be accepted unless by written exemption from the Engineer. Unless authorized by the Engineer, no concrete shall be placed in any i.nit prior to the :crepletion of the form-work and the placement of the reinforcement. No concrete shall be placed before the completion of all adjacent operations which :night prove dltrimegttl to'the concrete. Whenever it is necessary to continue the mixing, 'placing', and finishing of concrete after the daylight hours, the'aite of'th! wdrk shall be brilliantly' lighted so that all operations are pi'ainly visible. In general, however, concrete placing shall be so regulated as 'to e~mit'''fIInish'ing dperations, to bi c completed 16 the ,dztylight hoyrs.'

The placing of concrete for floor slabs pre- ' ferably shall be done by a mixing plant located off the structure, eartfag or wheeling concrete batches on a completed concrete floor slab will not be permitted until the slab has aged at least lour curing days. Unless pneumatic tired carts are used, the carts shall be wheeled on timber planking so thit the loads and impact will be distributed over the slab. Curing operations shall not be interrupted for the purpose of wheeling concrete over finished slab6. Stockpiling of concrete aggregate or cement on floors will be permitted only when authorized by the Engineer. The storing of rein- torcing or structural steel on site ccmpleted shall generally be ayoided, sad when permitted, such storage shall be limited to quantities and distri- , button as authorized by the Engineer. c. RIDgeei_ting: The method and mannen of placing shall be such ae to ovn4l tht. oobbibility of segregated or separation of the aggregate or the displr,cement of the reinforcement. In thin walls, drop chutes of rubber or me-n! shall be used. The spattering of forms or reinforcement bars shall be prevented if the concrete so spattered will dry or harden before being ini-orpotated in the masa,, Each part of the forms shall be tilled by,,depoaiting concrete directly as near its final position as possible.

Consolidation: Each layer of concrete shall be well compacted and the mortar flushed to the surface of the forms by continuous working with mechanical vibrators of an approved type. Vibrators of the type which operate by attachment to forms will be permitted only when immersion type vibrators cannot be used due to inaccessibility. The vibrators shall be applied to the concrete immediately after deposit and shall be moved through- out the mass, through the layer of concrete just placed, and several inches into the plastic layer below, thoroughly working the concrete around the reinforcement, embedded fixtures, and into the corners and angles of the forms until the concrete is thoroughly compacted. Mechanical vibrators .shall not be operated so that they will penetrate or disturb layers placed previously which have become partially set or hardened, and they shall not be used to aid the flow of concrete laterally. The vibration shall be of sufficient duration to accomplish thorough compaction and complete embedment of reinforcement and fixtures, but shall not be done to an extent that will cause segregation. Vibrators shall be kept constantly moving in the concrete and shall be applied vertically at points uniformly spaced, not farther apart than the radius over which the vibrator is visibly effective. The.vibrator shall not be held in one location longer than is required ,to;prodme a liquified appearance on the surface. Incernal vibrators.shall maintain a frequency when submerged in i,thei concrete of:: aot less:.than. 6,000 impulses per minute for, spuds with dipasters greater than 5 inches and 20,000 impulses for smaller spuds. i TJor iviXmsi4y. (amplitude) of vibration shall be sufficient to produce satis- factory consolidation. A sufficient number of vibrators (powered pneumatically or, electrically) shall be used to provide one for each ten cubic yards of concrete per hour being placed. At least one vibrator, which may be of the gasoline powered. type, shall be immediately available as a standby for each two;vibrstore in service. The~Engineer may require the Contractor to use # vibrator of larger,size,and power if he feels, based on observed per- formanca~ that it.is necessary to produce satisfactory consolidation. All vibrators intended for regular service or standby service shall be checked and approved by the Engineer prior to the beginning of the concreting operations. e. Embedded Items: Before placing concrete, care shall be taken to determine that all embedded items are firmly and securely fastened in place as indicated in the drawings or required by the Engineer. All embedded items shall be thoroughly clean and free of oil and other foreign material. Apchor bolts shall be set to exact locations by the vse of suitable anchor bolt templates, or as otherwise shown on the plans. 2. Placing Concrete in Cold Weather: No concrete shall be placed when;the atmospheric temperature is at or below 40 degrees F. Ltaken IT, the,shade:away from artificial heat) unless permission to do so is given'in n ;writing, by the Engineer. When. such permission is givev, or in cases where the temperature drops below.40 degrees P. after the concreting operations havefbeen. start*4 ,.lthe Contractor shall furnish sufficient canvas and fraswwork.or,othou type of, housing to enclose and protect. the structure in.such a wsy~thar'the air a'romid the forms and fresh concrete can be kept 101-11 at a temperature not less than 50 degrees F. for a period of five days after the oorrcrete is placed for normal concrete, and for three days fop high-early-strength concrete, Sufficient heating apparatus such as stoves, salamanders, or staan equipment and fuel to furnish all required heat shall be supplied. The treatment of mixing water and aggregates used in mixing concrete shall be as specified in "Concrete for Structures". It is under- stood that the Contractor is responsible for the protection of concrete placed under any and all weather conditions. Permission given by the Engineer to place concrete during freezing weather will in no way relieve the Con- tractor of the responsibility for satisfactory results. Should concrete placed under such conditions prove unsatisfactory, V. shall be removed and replaced. 3. Placinit Concrete _iU water: Concrete may be deposited in water only when specified on the Plans or with the permission of the Engineer. The forms, cofferdams, or caissons shall be sufficiently tight to prevent any water current •?assing through the space in which the concrete is being deposited,, -Pt ping wi1L rot be ,srmitted while the concrete to being placed, nor until, it has gtt for A least 36 hours. The concrete shall be care-' fully placed in a compact-mass°by means of a tremie,-closed bottom-dumping bucket, or other approved method that does not permit: the concrete to fall " through'-thelwhter"without adequbte prote6tion6 The concrete shall not be disturbed 'after-being depoaite&',,Depdsiting shall be regulated to maintain approximateiV. horiteohtal Wrfade+.a 'at all' timm: Wheal a treaia' is. naedit;, it shall, consist 1 of, a' tube having a'diameter of not, toore than too, inches, tiotulf.

The number ofjtimss'i t its necessary to shift the location of the tremia,/for any contlnuouk pladement of concrete', shall be held to atminimumb! During the placir{g bf, eonctrew the, tremis tube, shall be kept full to' the bottom .of the hopper, when a batch is dumped into the hopper, the tremis shall be slightly raised,!but not out of the concrete at the bottom, until the batch discharges to the level of the bottom of the hopper. The flow shall then be stopped by lowering the tremie. The placing operations shall be continuous-until the work is completed. When concrete is placed by means of-the bottom-dump bucket; the bucket shall have a capacity of not lose than ono-half cubic yard< The bucket shall be lowered gradually and carefully until;ic rests upon the concrete already placed. It shall then be rai.aed very slowly during the discharge travel; the intent being. to maintain; as nearly. as possible, still water at the point of discharge and to avoid agitating the mixture. rr 4;-~ Placihtc Conceet Slabsk Concrete in, columns, walls, and deep. rt beams or girdare,6hali-b'elallowed to stand for, it least one hour,' of mott ivyspecifLed by the, Engineer, i to permit, full settlement, due to consolidation before cpnclreta,ls~placed in'the slabs,they,are to support, Haunches art condidered as, part oft the blab, rani sheik be, placed inte4raily' with themb-{ The surfaces and material over,O ich a slab plated on'the!ground'is to ba ,poured shall, be ins accordance with' rha' Item, "Earthwork".

S. Placing Concrete in Foundations: Concrete shell not be placed in footings until the depth and character of the foundation has been inspected ;by the Engineer and permission has been given to proceed. The placing of concrete bases above seal courses will be pe mitted after the forms are free from water and the seal course cleaned. Any necessary pumping or boiling during the concreting operations shall be done from a suitable sump located outside the fords. Concrete in deep foundations shall be placed, in r+ manner that will avoid separation of the aggregates or displacement, of this reinforcement. Suitable chutes or vertical pipes shall be provided.

Curing compound shall be applied immediately after any patch is made unless other curing is provided. Seal coats shall remain in place and be protected against abrasive action for a period of 28 days if in an area where 14- day curing is required and 14 days if In an area where 7-day curing is required, Seal toots on slabs shall be protected by a one-inch layer of s4nd or earth or,by other approved means. The protective coating shall not be placed sooner than 24 hours after the seal coat has been applied. Any damages to the membrane coating within the period of time noted above shall be repaired immediately by a liberal application of the compound. M. Removal of Forms and Falaework: Except as hereinafter provided. forms for surfaces required to be rubbed shall be removed when the concrete has aged not less than 18 hours, nor more than 7 days after the concrete is placed. Forms shall be removed from surfaces reguiriae a rubbed finish only.as;rapidiy as the,rubbin6 operation cap g mtress,, in.order to.permit more rapid and more satisfactory tubbing while the surface is Soist and relativsly:aoft.
