6zI- During the field investigations of this project tFaffic control for the public safety will be maintained. The disruption of traffic will be minimized. ADS will abide by the traffic control procedures outlined in the ADS Field Safety Manual. However, these guidelines will not override local or state traffic control regulations. Two copies of this manual will be provided to the CITY. B. Above Ground Reconnaissance! Map Update This data will supply background base data to be used during the collection system analysis. Above ground physical inspection is to be performed to determine the physical condition, location and length of the sewer system, to identify covered manholes, and to verify and update the sanitary sewer collection system map. The following data to be recorded is to include, but not be limited to: - Length between manholes - Identification of each manhole in accordance with the Black and Veatch established criteria - Identification of covered or unlocated manholes - Identification of visible sources of extraneous flow - Notation of unusual conditions that may require immediate attention - Confirmation of flow direction . C. Manhole InspectionNisual Pipe Inspection Internal inspections of 100% of all sanitary access structures within the project will be conducted. Industry standard OSHA, NIOSH, OSDA and NASSCO confined space entry policies and practices will be followed to ensure safe entry and egress of all access structures. In the event of conflicting requirements, OSHA standards will prevail. Photographic images will be taken of selected defects indicating the general surroundings of each manhole. All manhole components (i.e., cover, frame, frame seal, chimney, corbel, wall, etc.) will be inspected and recorded on standard field inspection forms. Pipe diameter measurements will be rounded to the nearest industry standard pipe diameter (i.eo, a measurement of 7.75" will be recorded as 8.0"). The rim-to-invert measurements, in tenths of feet, and general orientation for all connecting lines will be recorded. A minimum of 20 minutes will be spent in locating structures in order for the access inspections to be counted for payment. A list of "could-not-Iocate" or "inàccessible" access structures will be submitted to the CITY. Once the CITY has located and provided access to these structures, ADS will complete all necessary inspections at no additional cost to the CITY prior to the completion of field activities. F or structures located and access provided after completion of field services, a remobilization charge will be assessed. All new access structures located will be properly identified on City sewer atlas maps and provided to the CITY. G:\OA LLAS\C aNTRA CT\SA NMAR CoDOC June 25, 1996
