Metropolitan St. Louis Sewer District
Project to rehabilitate the Vance Road Pump Station (built in 1986). Goal is to provide a structure that meets current codes including building, safety, fire, floodplain, etc., and has a useful remaining service life of at least 30 years. The station was in good condition, except for flooding issues during rain events, due to influent sewer capacity being 2 or 3 times the pumping capacity. Flooding has led to corrosion issues and deterioration of the lower portions of the structure. Building entrances and interior electrical and control gear are not above the revised 100 year and 500 year flood water elevations, and are subject to flooding. The station did not meet current codes, so modifications were required to bring the station into compliance. Specific engineering services during construction include: shop drawing and submittal reviews (including O&M manuals), perform site visits and respond to questions received from District or Construction Manager regarding project design and provide details for any changes, provide start up assistance, provide as-built drawings, attend progress meetings (including pre-construction meeting).
