TECHNICAL SPECIFICATIONS B. No clearing shall be performed until written permission is given by MANAGER and until the CONTRACTOR has provided construction staking for the proposed work. Clearing shall consist of cutting brush to the ground level, removing such material, along with wood, rubbish, tree stumps, and any other vegetation with roots in excess of 1 -inch diameter, and other deleterious materials, and disposing of all such material in the accepted manner described below. C. In areas designated to be stripped of unsuitable or objectionable material, said materials shall be stripped to the full depth of organic or other unsuitable material as determined by MANAGER and CERTIFYING ENGINEER, whichever is greater. D. Stripped and grubbed vegetation shall be removed and disposed in stockpiles or other approved methods in an area designated by MANAGER. 3.2 WASTE REMOVAL A. Waste material is defined as material too wet, too dry, frozen or containing ice or snow, containing organic or other deleterious matter, having poor characteristics of grading or compaction, having other characteristics that may result in undesirable settlement or other movement of the fill, or within the fill, or otherwise not meeting the requirements of the SPECIFICATIONS, provided that this definition permits drying, water, and any other processing or reprocessing to make the material stable and suitable prior to incorporating it into the fill as permitted in the SPECIFICATIONS or by the MANAGER and CERTIFYING ENGINEER. I. CONTRACTOR shall excavate and remove waste in a manner that will minimize contamination with other soil horizons. 2. CONTRACTOR shall stockpile removed waste at locations designated by MANAGER. 3.3 EXCAVATION A. CONTRACTOR shall perform excavation to the lines and grades shown on the DRAWINGS or as directed by MANAGER. No excavation shall begin until the CONTRACTOR has provided construction staking for the proposed work. B. CONTRACTOR shall prevent the disturbance of surrounding areas during excavation. Where selective excavations are required to obtain materials for Select Structural Fill, the material removed from the excavations shall be taken directly to the fill areas or, if required, stockpiled by material types. The stockpiles shall be approved by MANAGER. C. CONTRACTOR shall grade all excavations to ensure grades are maintained to provide adequate drainage at all times. Work shall be suspended by CONTRACTOR when, in the opinion of MANAGER and CERTIFYING ENGINEER, the site is overly wet, muddy, or otherwise unsuitable for proper maintenance, until directed otherwise by MANAGER, at no cost to CC &V. D. In excavations where Select Structural Fill is to be placed on slopes steeper than 4H:1 V, horizontal benches shall be excavated into the slope to allow fill to be placed in horizontal lifts. The CONTRACTOR shall continuously bench and key embankment material into the existing material a minimum of 2 feet. E. The CONTRACTOR will be responsible for the safety of temporary construction slopes. CONTRACTOR shall inspect all temporary and permanent open -cut excavations on a regular basis for signs of instability. Should signs of instability be noted, CONTRACTOR shall immediately undertake remedial measures and shall notify MANAGER immediately. All slopes shall be left in smooth, safe, and stable condition at the end of the workday. F. CONTRACTOR shall final grade excavations within the Pipe Rack Liner Extension to establish positive drainage to the adjacent storm water collection pond. In no case will depressions or bowls be permitted in the Pipe Rack Liner Extension area.
