SECTION 3 - SPECIFIC REQUIREMENTS <br />3.1 Consumables <br />The Developer shall supply all consumables required to install the conduit and vault system. <br />Such consumables may include but are not limited to: <br />Sand, backfill, asphalt, concrete, landscaping etc. <br />3.2 Earthwork <br />Care shall be taken for adjacent structures and utilities. Where sidewalks or curbs are cut, <br />paving shall be removed to the nearest construction joint. The Developer shall be liable and <br />accountable for any damage due to Developer -performed excavation. <br />Excavation for vaults shall be of sufficient size to leave not less than one foot clearance <br />between the bank of the excavation and the vault. Sand bedding is required adjacent to <br />primary raceway apparatus. <br />Trenching for underground ducts shall be true to line and grade as shown on the drawings <br />and staked in the field at a minimum of 42" depth typically. Banks of trenches shall be kept <br />as vertical as possible. Duct trenches shall be maintained free from standing water when <br />ducts are being installed and shall be cleaned of excess and loose rock and loose earth before <br />installation of sand, per trench details provided in APPENDIX A — MATERIAL SPECIFICATIONS. <br />Bedding material may be placed with backhoe with redistribution by hand to ensure proper <br />cover and that subsequent backfilling operations do not disturb the duct. <br />Excavation materials may be used for backfilling, but not for bedding, provided it is free of <br />frozen particles or lumps, vegetable matter or foreign debris, large rock, paving materials or <br />cinders per trench details provided in APPENDIX A— MATERIAL SPECIFICATIONS. Backfill shall <br />not be placed until after inspection of the underground facilities has been completed and <br />approved in writing by the City Light Inspector. Backfill shall be compacted to 95% of the <br />maximum density of the surrounding earth. <br />Ducts must be bedded with sand per City specifications. Bedding shall include partial backfill <br />to a level appropriate for the positioning of trench marking tape (approximately one lift of <br />dirt backfill). This shall also include the positioning of said trench marking tape. <br />Joint trench occupation by the local telecommunications companies and City Utilities are <br />typical. Joint installation shall be coordinated by the Developer, when requested by the City. <br />Underjoint trenching scenarios, the Agreement shall include coincidental bedding and backfill <br />of all joint trench facilities. <br />3.3 Ducts <br />A minimum of six inches of sand bedding and shading shall be used to encase the ducts with <br />a minimum depth; per trench details provided in APPENDIX A — MATERIAL SPECIFICATIONS. <br />Page 6 <br />JOB #3450-316 FAIRGROUNDS RV PARK 3PH EXTENTION, DEVELOPERS AGREEMENT <br />
