in the approved Plan shall undertaken by the Contractor under the control ofthe Engineer to serve as basis for the computation of the actual volume of theembankment materials.Embankment of earth material shall be placed in horizontal layers notexceeding 200 mm (8 inches), loose measurement, before the next layer isplaced, However, thicker layer maybe placed if vibratory roller with highcompactive effort is used provided that density requirement is attained and asapproved by the Engineer. The Contractor shall compact the material placed inall embankment layers and the material scarified to the designated depthbelow subgrade in cut sections, until uniform density of not less than 95 masspercent of the maximum dry density determined by AASHTO T 99 Method C, isattained, at a moisture content determined by the Engineer to be suitable forsuch density.The quantity of embankment to be paid for shall be the volume of materialcompacted in place and accepted by the Engineer.PART B1 -CONCRETE AND MASONRY WORKSItem 404 Reinforcing SteelPlacing of steel reinforcement shall be in accordance with the Specification and inconformity with the requirements shown on the Approved Plans or as directed bythe Engineer. Steel reinforcement shall be deformed bars with a minimum tensilestrength of 33,000 psi.Steel reinforcement shall be stored above the surface of the ground uponplatforms, skids, or other supports and shall be protected as far as practicablefrom mechanical injury and surface deterioration caused by exposure toconditions producing rust. When placed in the work, reinforcement shall be freefrom dirt, detrimental rust, loose scale, paint, grease, oil or other foreignmaterials.All reinforcing bars requiring bending shall be cold bent to the shapes shown onthe Plans or required by the Engineer. It shall be accurately placed in the positionshown on the Plans or required by the Engineer and firmly held there during theplacing and setting of the concrete. Bars shall be tied at all intersections exceptwhere splicing is less than 300mm in each directions, in which case, alternateintersections shall be tied, Ties shall be fastened on the inside inside.Reinforcement in any member shall be placed and then inspected and approvedby the Engineer before placing of concrete begins. Concrete placed in violation ofthis provision may be rejected and removal may be required.All reinforcement shall be furnished in the full lengths indicated on the approvedplans. Splicing of bars, except where shown on the plans, will not be permitted84Clark Development Corporation Proposed Renovation of Former Jacinto Building(Motorpool, Records, Warehouses and Maintenance Area)
