MOTION
Upon recommendation of Marqaicha Welch, Procurement Manager, the Board of Water Commissioners for the City of Detroit, Water and Sewerage Department authorizes the Director to approve DWSD Contract 6006991 (DWS-970) with L. D'Agostini and Sons, Inc., for Sewer Reconfiguration Project Near Riverside Park; for a total contract amount not-to-exceed $6,274,863.50 and a term of 456 days. This also authorizes the Director to take such other action as may be necessary to accomplish the intent of this vote.
BACKGROUND / JUSTIFICATION
DWS-970 is Stormwater Sewer Separation Project which will address sanitary sewer overflows in the City of Center Lind by providing additional capacity in the Detroit River Interceptor to discharge more sanitary flow into the Great Lakes Water Authority (GLWA) system. The improvements will include increased pumping capacity. This contract was generated from an agreement which was entered by and between the CITY OF DETROIT, acting through its DETROIT WATER AND SEWERAGE DEPARTMENT, the CITY OF CENTER LINE, and the GREAT LAKES WATER AUTHORITY. The Parties entered into this Agreement to:
(i) memorialize Center Line’s obligation to reimburse costs up to the $6 million maximum for the Offsetting Project,
(ii) memorialize DWSD’s obligation to construct the Offsetting Project, to complete all reporting requirements of the Grant Agreement and to meet the Final Due Date as set forth in this Agreement,
(iii) control the access to and the activities upon the Property by Center Line, its employees, engineers, consultants, bidders, contractors, subcontractors, and agents (collectively, “Center Line’s Agents”) during construction of the Improvements, and
(iv) provide for the coordination of activities between GLWA and Center Line that will be critical to the successful completion of the Improvements.
The need for additional capacity in the regional sewer system is identified in the scope of DWS-970, as potential to create sufficient capacity to address the need for the City of Center Line and benefit DWSD with establishing a storm-only system for the project area.
The outfalls B032 & B033 will be converted into storm only outfalls upon completion of this project and decommission them from the Detroit Riverfront Interceptor (DRI). As this project will install a new sanitary sewer to support the existing customers in the project area, the design has incorporated the necessary measures to convert the area from a combined sewer system to a storm only system.
The timeline impact for the funding and required Final Report have instituted the contract term to end July of 2026. As part of the Agreement, DWSD shall provide its final report to Center Line upon completion of the Offsetting Project, with associated invoices (the “Final Report”), on or before September 15, 2026 (the “Final Due Date”).
