mixed on-site, equipment and mixing procedures shall conform to ACI 301, Chapter 7. If <br /> 'ready mix' is used, it shall be mixed and transported in accordance with ASTM C 94. <br /> Concrete shall be thoroughly compacted by means of a suitable mechanical vibrator. <br /> - Upon completion of concrete curing, the dirt excavated from the embankment shall be <br /> replaced on top of the new concrete. The material shall be replaced in such a manner so that <br /> the slope of the embankment is returned to its original condition, and so that the top of the <br /> CMP riser is six inches (6") above the elevation of the embankment slopes. The fill shall be <br /> mechanically compacted during placement. <br /> A hinged steel grate shall be placed over the top of the CMP riser. The grate shall be <br /> constructed using 1-1/4" structural rebar welded on eight-inch (8") centers in both directions. <br /> Two (2) extra heavy-duty hinges, having non-removable pins shall be welded to the CMP riser <br /> and to the steel grate cover on the uphill side of the riser. A hasp, constructed of 3/8" steel, <br /> and having a circular hole of'h" diameter, shall be welded to the CMP riser and the steel grate <br /> on the down hill side of the riser. <br /> Measurement and Payment <br /> There will be no measurement for payment. Payment for this task will be reflected in a lump sum <br /> bid under Item 3 on the Bid Schedule. This lump sum bid will cover all costs for cutting of the CMP <br /> riser, offsite disposal of the excess CMP material, excavation of the embankment, form <br /> construction, purchase and installation of the bentonite, purchase and installation of the concrete, <br /> backfilling and compaction over the concrete, construction and installation of the hinged steel <br /> grate. Payment shall be as this task is completed and approved by the PROJECT MANAGER. <br /> Such payment shall be considered full compensation for all labor, materials, equipment and all <br /> other items necessary and incidental to the completion of Task 3, Sediment Pond Dewatering <br /> Device Repair. <br /> Task 4 Sealing Sediment Pond <br /> In order to minimize the infiltration of water from the sediment pond, bentonite will be placed within <br /> the pond. Bentonite shall be placed on the base of the pond and up the side slopes to the <br /> elevation of the lowest inlet of the CMP riser. <br /> CONTRACTOR shall ensure that the pond is free of water prior to initiating this Task. Upon <br /> completion of dewatering, if necessary, CONTRACTOR shall stake the elevation of the side slopes <br /> of the pond at the elevation of the lower most inlet to the CMP riser. In order to ensure that the <br /> proper elevation is established, the use of a tripod mounted surveyors level is required. <br /> The surface area of the pond to be affected by this Task shall be scarified to a depth of four inches <br /> (4") through the use of a disc harrow. Two inches (2") of dry bentonite shall be placed on the <br /> prepared work area after the discing is completed. This material will be worked into the base and <br /> side slopes of the pond by discing the affected area until the bentonite is well incorporated into the <br /> scarified surface. <br /> Measurement and Payment <br /> There will be no measurement for payment. Payment for this task will be reflected in a lump sum <br /> bid under Item 4 on the Bid Schedule. This lump sum bid will cover all costs for identifying the <br /> area to be affected by this Task, preparation of the area, and purchase and installation of the <br /> bentonite materials. Payment shall be as this task is completed and approved by the PROJECT <br /> MANAGER. Such payment shall be considered full compensation for all labor, materials, <br /> 5 <br />
