751/23180. ABG; Mackinac Island East Bluff Retaining Wall

The Michigan Department of Technology, Management and Budget (DTMB) and Mackinac Island State Park Commission are soliciting bids for the Mackinac Island East Bluff Retaining Wall Replacement project, a comprehensive infrastructure improvement initiative. The procurement involves selective demolition, site clearing, earthwork, and construction of a new modular block retaining wall along the East Bluff of Mackinac Island, with detailed specifications for utility protection, drainage installation, backfilling, grading, and asphalt replacement. The project is divided into two phases: Phase I, to be substantially completed by December 19, 2025, focusing on reopening the road, and Phase II, to be substantially completed by May 20, 2026, involving final grading, HMA paving, and restoration. The bid is scheduled to be received on Wednesday, May 21, 2025, at 2:00 p.m. Eastern Time, with a mandatory pre-bid meeting and site inspection on Thursday, May 8, 2025, at 11:30 a.m. Bid evaluation will consider both price and qualitative components, with contractors required to provide a 5% bid security, comply with prevailing wage rates, and meet erosion and sedimentation control requirements.

The contract includes potential preferences for Service Disabled Veteran Owned Businesses (SDVOB), with a 10% pricing preference established under Public Act 91 of 2005. To qualify for this designation, businesses must be at least 51% owned by one or more veterans with a service-connected disability and provide appropriate documentation. The project has a provisional contingency allowance of $30,000 and will be funded by the State of Michigan. Contractors must navigate unique logistical challenges, including material hauling to the island via British Landing and material staging in the State Park service yard after Labor Day, with transportation time restrictions until October 26, 2025. Additional requirements include obtaining City of Mackinac Island street permits, adhering to E-bike licensing requirements, and removing all excavated, demolished, and excess materials from the island. While no specific incumbent vendors are mentioned, the project demands significant technical expertise in maritime infrastructure, retaining wall construction, and site restoration in a sensitive island environment.
