Walsh Construction Awarded $92.9 Million Contract for Ann Arbor WWTP Project

Earlier this evening, the Ann Arbor City Council tentatively approved a $92,929,000 contract to Walsh Construction for major renovations to the City of Ann Arbor's wastewater treatment plant (WWTP).  As we reported (here), Walsh Construction was third bidder at the time this project was bid on January 11, 2012.

After the bid opening, the City and its engineering consultant, Malcolm Pirnie, met with the three low bidders and solicited additional information about their bids and prior experience building comparable projects.  

At tonight's meeting, officials cited a lack of comparable wastewater construction experience by the low and second bidders. City officials discounted Granger's recently-completed $70 million D.K. Shine Water Treatment Plant expansion for Wyoming Twp. because it wasn't a wastewater project and only had one tie-in at the end of the project, rather than the multiple tie-ins that will be required over the course of the Ann Arbor WWTP project.

Tentative approval of Walsh Construction's contract is required for the City of Ann Arbor to obtain a low interest loan from the State Revolving Fund (SRF) program administered by the Michigan Department of Environmental Quality (MDEQ) to finance construction.
