The Metropolitan St. Louis Sewer District has named Kwame Building Group, Inc.

KWAME will provide constructability/biddability reviews during the design phase to confirm feasibility, completeness, consistency and construction cost estimates of the plans. KWAME also will review all final documents before advertisement for construction bids and serve as the MSD representative during construction to ensure that the Contractor meets all performance, quality and safety obligations..
