Attached for your review and approval is a resolution to award a contract to Dunigan Brothers, Inc. in the amount of $462,458.00 for the Stadium and Iroquois Water Main Replacement Project.
The construction contract titled “Stadium and Iroquois Water Main Project” includes the installation of new 8” water mains at Iroquois Place and East Stadium Boulevard. The work includes approximately 3,350 feet of new 8” ductile iron water main to replace the existing 4” and 6” water main that serves the houses on East Stadium and Iroquois. This work will provide a more reliable water service for the neighborhood, and conform to City of Ann Arbor water main and fire protection standards by upsizing the pipe, and adding four new fire hydrants. As part of this construction contract, the street will be resurfaced, and adjacent sidewalk ramps will be replaced to comply with the ADA requirements.
