SHEET Laying, compacting and finishing shall be in accordance with Article 1007 of the 1985 Standard State Specifications and its revisions or addendums. Flagging and barricades necessary for construction will not be paid for directly, but will be subsidiary to the contract. CONTRACTOR'S NOTE 1. Payment will be made for actual field quantities utilized and shall show precedence over contract estimated quantities. 2. Locations of all manholes and valves will be tied off and recorded prior to any work. Manholes will be kept covered and kept clean throughout all of resurfacing project. 3. All drives and approaches will be asphalted back, as directed by Engineer in field. 4. It will be the responsibility of the Contractor to dispose all pavement removal. 5. Any earth excavation will be hauled to City stockpile as determined by Engineer. 6. Contractor will be required to notify property owners a minimum of 24 hours prior to any work being started, so cars, etc. can be moved. 7.
