NOTE 1: The width of the trench is to be as specified by the Engineer on theplans or as set forth in the Specs. Max. trench width and depth must be asspecified in Tables 10.4 and 10.5. Trenching methods must be in compliance withthe Va. Department of Labor and Industry (VOSH) requirements.NOTE 2: The pipe must be bedded in carefully compacted granular material placedon a flat trench bottom. The granular material must be crushed stone VDOT size57, 68, or 78, in accordance with VDOT Spec. Section 203. The granular beddingmust have a min. thickness of 1/4 the outside pipe dia. (4” min.) and mustextend vertically in accordance with alternatives A or B. If the max. width of thetrench at the top of the pipe exceeds those specified, granular bedding materialwill be brought to the top of the pipe for the full width of the trench. Theremainder of the side fills and a min. depth of 12” over the top of the pipemust be filled with carefully compacted material. Should the contractor elect touse larger stone to carry the water, the larger stone is to be placed beneath thespecified amount of granular material. The larger stone is not in any way toaffect the amount of granular material to be used.
