Prior to the beginning of the rock installation, the geo-textile blanket and the drain system will be <br /> inspected by General Contractor, Installation Contractor, Owner and Landscape Architect for proper <br /> placement and structural integrity. Installation Contractor will accept condition of geo-textile prior to <br /> starting his work. Said Contractor at his expense will repair all damage to the geo-textile fabric due to <br /> the execution of his work. Any and all tears, rips or holes shall be repaired after removal of damaged <br /> goods with new material overlapped on all sides a minimum of 12" over installed material and held in <br /> place by drain rock until backfilled. <br /> 3.2 INSTALLATION OF ROCK SUB-SURFACE: <br /> A. Placement, grading and compaction of the base materials require great care. Improper handling, <br /> placement, grading and/or compaction can result in irreparable damage to the intended function of the <br /> base. Contractor shall closely adhere to the manufacturer's installation recommendations and assumes <br /> all risks and liabilities associated with inadequate function of the base system, including removal and <br /> replacement. <br /> B. Bring the rock material initially to the peripheral areas of the field using single trucks and transfers. No <br /> pups or trailers will be permitted on the field. Push the rock onto the existing drainage membrane so as <br /> to make a road for the spreading the material. Truck traffic shall not be permitted on the drainage <br /> membrane. Rock spreading will be performed using wide track equipment only. The rock material will <br /> not be pushed more than 50' (fifty feet) in any direction. Any and all damage done to the drainage <br /> membrane or other utility or structure will be repaired or replaced to the satisfaction of Owner and <br /> Landscape Architect. <br /> C.
