MSD-BCMM FF-16 Schuetz – Phase II

Summary

Kaskaskia Engineering Group, LLC (KEG) provided geotechnical and environmental services to the Metropolitan St. Louis Sewer District (MSD), as a sub-consultant to AMEC Foster Wheeler (AMEC), now Wood. Wood is the Watershed Team lead, for the Bissell Coldwater-Missouri-Meramec (BCMM) Sanitary Systems Improvements project for the MSD $4.7 Billion dollar – Project Clear initiative. The FF-16 Schuetz project is one of 36 sewer design projects under the contract. The FF-16 Schuetz project entails 8,880 feet of proposed sewer improvements with a majority in carrier tunnels along Page Avenue and Schuetz Road in the City of Maryland Heights in St. Louis County, Missouri.

Project

KEG provided geotechnical services consisting of field exploration, laboratory testing, analysis, and reporting for the alignment and proposed appurtenances, such as manholes and laterals. KEG environmental services performed a Wetland Survey for the proposed alignment along Fee Fee Creek. Forty-two borings were completed for the project to depths of 7 to 33 feet below existing grades. Bedrock was encountered in 21 of the 42 borings. Twenty feet of rock core was obtained as part of the field exploration. KEG’s coordination with property owners was a critical part of obtaining access to drilling locations and for the successful completion of the exploration within the project schedule.

Reporting consisted of both a Geotechnical Data Report (GDR) and a Geotechnical Interpretive Report (GIR) for inclusion in contractor bidding specifications. Details of these reports included location and general description of existing fill materials, the influence of groundwater and/or rock on design and construction, and further geotechnical construction recommendations.

KEG also performed wetland delineations and completed Section 404 permitting for the project. KEG’s Environmental Team carried out wetland delineations and prepared a wetlands report for the project. The work was accomplished following appropriate US Army Corps of Engineers regulations and guidance documents, as well as pertinent and applicable state and local requirements. KEG completed a site reconnaissance and data collection visit to delineate any potential wetlands and waters of the U.S. within the project area. Wetland and stream boundaries were recorded using GPS. Summary information regarding wetland determination sites and waters of the U.S. was presented in a waters and wetland delineation report, which was submitted to the client.
