The City Council of the City of E1 Segundo, Cali- fornia, does resolve, declare and determine as follows: SECTION 1. That the following Special Provisions, being and to be known as "SPECIAL PROVISIONS OF THE CITY OF EL SEGUNDO, CALIFORNIA NUMBER 471210 FOR REINFORCED CONCRETE SANITARY SEWER PUMP PIT," dated December, 1947, be and the same are hereby adopted: "REINFORCED CONCRETE SANITARY SEWER PUMP PIT "DESCRIPTION OF WORD The work to be done under these special provisions shall consist of the furnishing of all necessary materials, appliances, tools, equipment, labor, and transportation for the excavation and construction of a sani- tary sewer pump pit and appurtenances at the northwesterly corner of E1 Segundo Boulevard and Standard Street in the City of E1 Segundo, California, as shown upon Plan No. 471210, and described in these special provisions and Specifications No. 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. 1- a ;r CEMENT: All cement used shall be Portland Cement and shall conform to the "Standard Speci- fications 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 thirty per cent (30%) of the bulk passing a 30 -mesh sieve, nor more than six per cent (6;%) passing a 100 mesh sieve. Pea gravel and crushed rock shall be hard, durable, and of a quality satisfactory to the Engineer. All rock shall pass a two (2) inch screen and not more than thirty -seven per cent (37 %) shall exceed three - fourths (3/4) of an inch in diameter. All aggregates shall be free from clay, loam, mica, organic material, or other impurities. In propor- tioning the aggregate 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 mix- ture as possible may be obtained. The nominal proportion of the aggregate shall be as specified for each portion of the work. WATER: Water 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 shapes and sizes as are shown on the detailed drawings furnished by the Engineer. The steel shall be rolled from original billets, of medium grade, and according to the Standard Specifications of Steel Manufacturers 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 be tested shall be selected at random from Contractor's stock pile. The tests shall be made by a re- cognized laboratory subject to the approval of the Engineer. 2- K Before being imbedded in the concrete, the surface of the steel shall be thoroughly cleaned of all dirt, rust, oil, grease 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 wire. EXCAVATION: The price bid for the work is to include all necessary excavation and backf1111ng and the disposal of any excess material, broken concrete or other refuse. The Contractor shall leave the entire area graded to the elevations shown on the plans. Extreme care must be exercised in the necessary excavation for all footings. CONCRETE: Concrete shall be considered as a homo- geneous mixture with or without rein - foroement, as specified and shown on the plans, made up of cement, aggregates and water properly mixed in an approved type of batch mixer. The various proportions of this mixture are specified under the section whose heading 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 mode to insure a more workable mix. The proportions of cement to aggregate 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 shall there be more than six gallons of water to one sack of cement, or its cubic foot equivalent of 94 pounds. MIX: 1part cement to 6 parts aggregate Walls Roof s Floor Slabs Soffits 3- 1 -part cement to 8 parts aggregate Footings FOOTINGS: The footings may be poured against dirt forms subject to the approval of the Engineer. In no case shall the soil on which the footings 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 CONCRETE: Should extra concrete be required by specific written instructions from the Engineer in the enlargement or deepening of the footings or increasing the depth of the structure over that called for on the plans, the Contractor shall furnish such extra concrete at a unit price as called for in the bid schedule_ 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 been 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 ,points as possible. These form boards shall be sized to both width and thickness. The walls are to be constructed with 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 r in place until, in the ,judgment of the Engineer, the con- crete 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 ( ?) days. All wall forms shall have a removeable section for cleaning out and inspection. All wall steel shall be wired and secured to the outside form. Where it is necessary to wire 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 CONCRETE WALLS: Before concreting, all forme shall be carefully and thoroughly cleaned of all sawdust, chips, and refuse. Immediately pre- vious to the placing of concrete, all forms shall be thoroughly soaked with 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 pockets being formed against the forms and the displacement of the reinforcement. Power vibrators are desirable, but not required. Noticeable voids or stone pockets discovered when the forms are removed shall be Imme- diately filled with mortar mixed in the same 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 point between the footing and the roof will be avoided. 5- No concrete shall be placed in the wall until the reinforce- ment 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 plan the placement of this material that there will be no cold construction joint. The ton of the slab shall be care - fully screened to true grade and then shall receive a steel trowel finish. The reinforcing mesh installed In the slab shall be handled in such a manner during the pouring of the slab that it is imbedded as nearly as 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. CURE_, 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 pauses must be properly and promptly rl- repaired by the Contractor at his own expanse. 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 trapesoidal 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. 6- 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 has initial set. Paper used around forms shall be left in joint space to aid in keeping out dirt and foreign matter. The Contractor at his option may suggest an alternate method of forming these joints, but a width of3 /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 thoroughly 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 space is then to be filled and rounded to 1/4" above the floor slab with the mastic compound. PIPE CONNECTIONS: 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 I -beams called for in the plans shall be placed accurately and with positive bearing on bearing plates as specified and 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. 7- 1 MANHOLE FRAMES AND COVERS: Manhole frames and covers shall be round, medium weight eastiron with an inside diameter opening of two feet (21) as manufactured by the Apex Steel Corporation or equal. MANHOLE STEPS: Standard 3/4" diameter steel manhole steps coated with red -lead, asphaltum or coal tar paint, shall be imbedded in the concrete from the manhole openings to the bottom of the pit as shown on the plans. PUMP FOUNDATIONS_ 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: •rhe 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.
