Thac the following Special Provisions, being and to be known as "SPECIAL PROVISIONS OF THE CITY OF EL SEGUNDO, CALIFORNIA NUMBER 471101 FOR REINFORCED CONCRETE SANITARY SEWER PUMP PIT ", be and the same are hereby adopted: " REINFORCED CONCRETE SANITARY SEWER PUMP PIT "DESCRIPTION OF WORK: The work to be done under these special provisions shall consist of the furnishing of all necess ^ry materials, tools, appliances, equipment, labor and transportation for the excavation and construction of a sanitary sever pump pit and appurtenances at Franklin Avenue and Arena Street in the City of E1 Segundo, California, as shown upon Plan No. 471107, and described in these special provisions and Specifications Number A.1941 entitled "General Requirements in Connection with Public Work in and for the City of E1 Segundo, California,' heretofore approved by the City Council of said city for said work. CEMENT: All cement used shall be Portland Cement and shall conform to the 'Standard Specifications and Tests for Portland Cement,' (Serial Designation C9 -30) of the American Society for Testing Materials. AGGREGATES: Aggregates shall be clean, well- graded and water washed. Sand shall, when dry, pass a one - fourth (1/4) inch screen with not more than 1- thirty per cent (30°lo) of the bulk passing a 30 —mesh sieve, nor more than six per cent (67) passing a 100 mesh sieve. Pea gravel and crushed rock shall be hard, durable, and of • duality satisfactory to the Engineer. All rock shall pass • two (2) inch screen snd not more than thirty —seven per cent (87") shall exceed three - fourths (3 /4) of an inch in diameter. All agr,regates shall be free from clay, loam, mica, organic material, or other im)urities. In proportioning the aggre- rate of the concrete, and in mixing the concrete, particular care and attention must be given to the relative coarseness of each part, and where necessary proportions shall be altered in order that as dense, uniform and workable a mixture as possible may be obtained. The nominal proportion of the aggrega=te shall be as specified for each portion of the work. 'WATER: :dater will be furnished to the Contractor by the City at the City's expense and at a location required by the Contractor. REINFORCEMENT: The Contractor shall furnish and set all steel required throughout the concrete work, all of which shall be deformed bars of such shapee and sizes as are shown onthe detailed drawings furnish- ed by the Engineer. The steel shall be rolled from original billets, of medium grade, and according to the Stpndard Specifications of Steel Manuf`,cturers for reinforcing steel. The Contractor shall, if required by the Engineer, furnish a test report on one tensile test and one bending test for each size of bar, the bars to br tested shall be selected at random from Contractor's stock pile. The tests shall be made by a recognized laboratory subject to the approval of the Engineer. Before being imbedded in the concrete, the surface of the steel shall be thoroughly cleaned of all dirt, rust, oil, 2_ �a gre -se or other matter that may be detrimental to the positive adhesion of the concrete. All steel intersections shall be tied with 16 gauge annealed wire. All steel splices shall be lapped 40 diameters and tied with Tire. EXCAVATiuw: 'the price bid for the work is to in— elude all necessary exca,ration and bac!�— filling and the disnosal of any excess material, broken concrete or other refuse. The Contractor shall leave the entire area graded to the elevations shown on the - ;lane. Extreme care must be exercised in the necessary excavation for all footings. CONCRETE: Concrete shad be considered as a homogeneous mixture •ith or without reinforcement, as specified -nd shown on the plans, made up of cement, aggregates and water properly mixed in an approved type of batch mixer. The verious proportions of this mixture are specified un"er the section whose hevding is MIX. Pre —mixed concrete is preferred but not required. Adjustments in the mix shall be made by the Engineer, on the job, and these will be made to insure a more Workable mix. The proportions of cement to agEregate will not be changed in any class of work; only the various proportions of the various sizes of aggregate may be changed. In no case shell there be more then six gallons of *eater to one sack of cement, or its cubic foot equivalent of 94 pounds. MIX_ 1 part cement to 6Darts_aggregate Wa11 s Roofs Floor dabs soffits 1 pert cement_ to 8parte__agL :mate Footings 3— r, FOOTINGS: The footings may be ooured sgsirsi, dirt forms subject to the approval of the Engineer. In no case shall the soil on which the foot- ings or tank slabs are to rest, be disturbed. All steel In these footings is to be placed in accordance with the plans and securely wired in place. EXTRA_CON_CRETEE: Should extra concrete be required by specific written instructions from the Engineer in the enlargement or deepening of the foot- ings or increasing the depth of the structure over that called for on the plans, the Contractor shall furnish such extra con- crete at a unit price as called for in the bid senedule. No extra compensation may be claimed unless written instructions have been received by the Contractor prior to the pour. FORMS: The Engineer will set grade hubs and will check the elevations of all form work, and no concrete is to be placed until forms have beer, checked by the Engineer. The walls and roofs of the structure shall be completely formed, and all forms are to be accurately centered, true, rigid and thoroughly braced. They shall be of sufficient strength to carry the entire dead weight of the construction as a liquid without deflection. As the walls of the pit are not to be plastered, special care shall be taken in laying up the form boards so as to obtain straight and as small joints as possible. These form boards shall be sized to hoth width and thickness. TT,e walls are to be constructed �Ath forms on both sides. No concrete will be allowed to be poured against earth banks except in the footings. All forms and shoring shall be kept In place until, in the judgment of the Engineer, the concrete shall have attained sufficient strength to resist Accidental thrust and other loads that may come upon it, and in no case shall their removal be sooner than seven (7) days. All wall M a �f forms shall have a removable section for cleaning out and inspection. All wall steel shall be wired and secured to the outside form. Where it is necessary to =sire the inside form, those wires may pass to the steel only. In no case shall the forms be tied with wires passing; through the concrete wall. PLACING OF_CONCxEPE_14ALL3; Before concreting, all forms shall be carefully and thoroughly cleaned of all sawdust, chips, and refuse. Immediately previous to the placing of concrete, all forms shall be thoroughly soaked ,vith water. The concrete shall thoroughly fill the forms, must be solid throuGhout, and in close contact with the steel reinforcement, It must be deposited continuously in uniform layers not over 12" in depth. The concrete shall be thoroughly tamped, special care being given to the tamping on both sides of the steel reinforcements to insure against stone poa:ets being formed against the forms and the displacement of the reinforcement. Power vibrators are desirable, but not reouired. Noticeable voids or stone pockets discovered when the forms are removed shall be immediately filled with mortar mixed in the aame proportion as the mortar in the concrete. The walls of the pit must be poured continuously in a single run in order that any horizontal construction joint between the footing and the roof will be avoided. No concrete shall be placed in the wall until the reinforcement has been inspected and approved by the Engineer. BOTTOM SLAB: The bottom slab shall be poured in a continuous pour and the Contractor shall so olan the -)lacement of this material that 5— I. i there will be no cold construction joint. The top of the slab shall be carefully screeded to true grade and then shall receive a steel trowel finish. The reinforcing mesh installed in the slab shall be handl6d in such a manner during the pouring of the slab that it is Imbedded as nearly <3s possible half way between the bottom and top of the slab. SUMPS: The sump in the pit shall be poured as an integral part of the floor slab. No construction or expansion joint in or around the sump will be permitted. DAMAGE.CUREl ETC.: Work must be protected from any damage resulting from temperature changes, or from the action of the elements at any time, and any damage from these or other causes must be properly and promptly repaired by the Contractor at his own expense. All work must be kept wet to the satisfaction of the Engineer for at least seven (7) days after being placed. EXPANSION JOINTS: The expansion joints in the structure shall be between the floor slab and the walls. Expansion joints shall be made of materials furnished by the Inertol Co., or the Aquatite Company, In the following manner: wood form strips of 2" materials, surfaced four sides to a trapezoidal section of height equal to the thickness of the floor slab and bases equal to 1..1/2" and 3/4" respectively are to be placed with roofing paper wrapping as shown on the plans. As concrete is poured it shall be carefully spaded at the forms to insure no rock pockets. Forms are to be removed as soon as concrete h,-s initial set. raper used around forms shall be left in joint space to aid in keeping; out dirt end foreign matter. 6- n w Ri The Contractor at his option may suggest an alternate method of forming these joints, but a width of 3/4" at the bottom and 1 -1/2" at the top must be maintained. When concrete has completely cured, joint space is to be thoroughly cleaned of all foreign matter and painted thorough- ly to at least 3" each side of the joint with primer solution as manufactured by the company whose expansion joint material is to be used. Oakum saturated with primer is to be then caulked into joint until the joint is at least one -half full. The remaining joint apace is then to be filled and rounded to 1/4" above the floor slab with the mastic compound_ PIPE CONvECTIONS: before concreting, the Contractor shall set in the walls pipes furnished by the City all as shown on the plans. The accurate position and location of these pipes shall be maintained during concreting. STRUCTURAL STEEL: All Lbeams called for in the plans shall be placed accurately and with positive bearing on bearing plates as specified end shall be wrapped with 2" wire mesh before being encased in concrete, when so Indicated on the plans. SIDEWALK DOORS: The sidewalk entrance door to the pit shall be an approved type of double sidewalk door, water proofed with drain, of a type to finish flush with the surface, and as manufactured by the Apex Steel Corporation or equal. MANHOLE FRAMES AND COVERS: Manhole frames and covers shall be round, medium weight castiron with an inside diameter opening of two feet (21) as manufac- tured by the Apex Steel Corporation or equal. MANHOLE STEeS: Standard 3/4" diameter steel man- hole steps coated with red -lead, 9.. 9, asphaltum or coal tar - >aint, shall be imbedded in the con- crete from the manhole openings to the bottom of the pit as shown on the plans. PUMP FFOUNDATiONS: Foundations for the pumps as shown on the plans are a part of this contract, and will be poured at the same time as the floor slab. MISCELLANEOUS: The Contractor shall furnish and install certain bolts, connectors and fittings as shown on plans. TIME: me Contractor shall commence work within fifteen (15) days after the execution of the contract and shall agree to complete the work within sixty (60) days thereafter.
