Borrow Soil: Satisfactory soil imported from off-site for use as fill or backfill. <br /> E. Drainage Course: Aggregate layer supporting the slab-on-grade that also minimizes upward <br /> capillary flow of pore water. <br /> F. Excavation: Removal of material encountered above subgrade elevations and to lines and <br /> dimensions indicated. <br /> 1.

Authorized additional <br /> excavation and replacement material will be paid for according to Contract provisions <br /> for unit prices. <br /> 2.

(0.57 <br /> cu. m) for footing, trench, and pit excavation that cannot be removed by rock-excavating <br /> equipment equivalent to the following in size and performance ratings, without systematic <br /> drilling, ram hammering, ripping, or blasting,when permitted: <br /> 1. Equipment for Footing,Trench, and Pit Excavation: Late-model,track-mounted hydraulic <br /> excavator; equipped with a 42-inch- (1065-mm-) maximum-width, short-tip-radius rock <br /> bucket; rated at not less than 138-hp (103-kW) flywheel power with bucket-curling force <br /> of not less than 28,700 Ibf(128 kN) and stick-crowd force of not less than 18,400 Ibf(82 <br /> kN)with extra-long reach boom. <br /> 2. Equipment for Bulk Excavation: Late-model, track-mounted loader; rated at not less <br /> than 230-hp (172-kW) flywheel power and developing a minimum of 47,992-Ibf (213.3- <br /> kN) breakout force with a general-purpose bare bucket. <br /> I. Rock: Rock material in beds, ledges, unstratified masses, conglomerate deposits, and boulders <br /> of rock material 3/4 cu. yd. (0.57 cu. m) or more in volume that exceed a standard penetration <br /> resistance of 100 blows/2 inches (97 blows/50 mm) when tested by a geotechnical testing <br /> agency, according to ASTM D1586. <br /> J. Structures: Buildings, footings,foundations, retaining walls, slabs, tanks, curbs, mechanical and <br /> electrical appurtenances, or other man-made stationary features constructed above or below <br /> the ground surface. <br /> Orange County Solid Waste Drainage Repairs DAA 2200365/TRC 017055.0000.0000 <br /> Drainage Repair Project November 2023 <br /> Orange County, NC 312000-2/13 <br />
