<br />6. Coordinate surveying and mapping to be performed by our subcontractor, Bohley <br />Consulting: <br /> <br />Conduct a ground control survey. Horizontal control will be referenced to NAD <br />1983, and vertical control will be referenced to NGVD 1929 + 100 feet. <br /> <br />Conduct aerial photography of the Sky Way, Bay Front, and Seaport Project <br />Areas. <br /> <br />Produce planimetric/topographic mapping for the Bid Package 4 and 5 pipeline <br />alignments. Topographic mapping will have a horizontal accuracy of 1.0 feet and a <br />vertical accuracy of 0.25 feet. <br /> <br />Conduct supplemental surveying with a horizontal accuracy of 0.5 feet and a <br />vertical accuracy of 0.25 feet. <br /> <br />7. Refine design criteria for locating recycled water distribution system appurtenances <br />such as line valves, blow-offs, combination air valves, fill stations, hydrants, and <br />potable water standby connections, etc. for use in the final design of the project. <br /> <br />8. Develop plan sheets for the pipelines, showing existing utilities and the proposed <br />alignments. Hand drawn sketches of alignment alternatives may also be periodically <br />submitted for City review. Traffic patterns and bus route information provided by City <br />will be considered when developing alignments. <br /> <br />9.
