established in the Bid Schedule, Item 1. The unit price bid will cover all costs for excavation, <br />and rock placement per specifications. The price bid shall be considered full compensation for <br />all equipment and materials necessary and incidental to completing the low water crossings to the <br />specifications of this Task. Payment shall be as this Task is completed and approved by the <br />PROJECT MANAGER. <br />Task 2 Rolled Dip Construction <br />A rolled dip will be constructed on the Pits 2 / 3 Road approximately four hundred feet (400') <br />above the low water crossing completed during Task 1, above. This rolled dip will be <br />constructed in order to move water from the south to the north side of the haul road. This rolled <br />dip will be constructed to the specifications of Figure 2, Rolled Dip Construction. (NOTE: <br />Steve: see facilities figure 3). <br />The dips will be constructed on an angle thirty degrees (30°) from perpendicular to the road <br />length. Excavated dirt shall be placed on the down slope side of the dip. The slopes of the dips <br />shall not be steeper than SH: 1 V. The depth of the ditch at the outlet as measured from the <br />downslope side of the road adjacent to the dip shall be two feet (2'). <br />Rock shall be placed within the rolled dip, including the base and the side slopes. The rock <br />placed in the pre-existing shall consist of two-inch (2") screened rock, overlain by clean four inch <br />(4") rock. <br />Durable rock is defined as rock material which gives off a ringing sound when struck with a <br />hammer. <br />Measurement and Payment <br />Payment for conswction of the rolled dips shall be at the unit price bid in Item 2 of the Bid <br />Schedule per rolled dip constructed. Such payment shall be considered full compensation for all <br />labor, materials, equipment and all other items necessary and incidental to the construction of the <br />rolled dips. Payment shall be as this task is completed and approved by the PROJECT <br />MANAGER. <br />Task 3 Sediment Pond Dewatering Device Repair <br />A sediment pond is located at the upper end of the Pit 4 haul road. This pond is known to leak <br />water from the base of the corrugated metal pipe (CMP) dewatering device. The goal of this <br />Task is to seal the base of the CMP through excavation and placement of bentonite and concrete. <br />The pond dewatering device is a forty eight inch (48") CMP riser, which is about ninety two <br />inches (92") tall, as measured from the base of the CMP at the water line. A horizontal CMP <br />spillway is connected to the CMP riser on the embankment side of the riser. The integrity of the <br />spillway (ie: its elevation and slope angle, as well as the integrity of the connection to the riser) <br />must be maintained throughout the duration of the Project. The riser is positioned at [he base of <br />the pond embankment so that the bottom of the riser is located just above the base of the pond. <br />The pond embankment rises from the base of the pond at an approximately 2H: 1 V slope to its <br />crest. The base of the riser is anchored by a concrete apron of at least ten inches (10") in width. <br />The thickness of the concrete apron is unknown. Water is observed to pipe around the outside of <br />the concrete apron. <br />In order to remediate problems associated with the CMP riser, CONTRACTOR shall <br />
