SAN-1233EV-RD-PP-CONT3-SHT10OF17.TIF

The file SAN-1233EV-RD-PP-CONT3-SHT10OF17.TIF is a project specification document involving the Detroit Water and Sewerage Department (DWSD) and Great Lakes Water Authority (GLWA) for the Walnut Lake No. 2 Conveyance CAP Phase II project in Michigan. The comprehensive infrastructure project involves extensive sewer system modifications, including removal and replacement of existing siphon pipes, construction of new sanitary sewer tunnels and connections, and significant modifications to existing junction, riser, and meter chambers. Specific work includes constructing temporary bypass conduits, slip lining existing pipes, installing new 66-inch and 78-inch diameter sewer sections, abandoning existing sewer lines, and performing structural, electrical, and telemetry upgrades.

The project encompasses substantial civil engineering work with multiple complex components, including procurement and installation of a new 96-inch sluice gate with electrical connections, site concrete work, asphalt paving, grading, and landscaping. While specific pricing details are not provided in the document, the project appears to be a critical infrastructure improvement initiative involving significant underground utility reconstruction along the M-39 Southfield Freeway and surrounding areas. The work requires sophisticated engineering techniques such as hand mining and precise flow management to minimize disruption to existing sewer infrastructure while upgrading system capacity and functionality.
