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

The Michigan Department of Technology, Management and Budget (DTMB), State Facilities Administration, is procuring construction services for the Mackinac Island East Bluff Retaining Wall Replacement project located on Mackinac Island, Michigan, in partnership with Mackinac Island State Park Commission and the Luce County and McBride Village jurisdictions. The scope of work includes selective demolition and removal of the existing retaining wall and fence, site clearing and earth moving, erosion and sedimentation controls, construction of a new modular block segmental retaining wall with heights ranging from 7 feet 6 inches to 10 feet 6 inches, installation of subdrainage systems, structural backfill, asphalt paving, and turf restoration. The project is divided into two phases, with Phase I requiring substantial completion by December 19, 2025, to allow road reopening for winter except for Hot Mix Asphalt paving, and Phase II requiring substantial completion by May 20, 2026, with final completion by June 19, 2026. Bids must be submitted electronically through the SIGMA VSS website by 2:00 p.m. Eastern time on Wednesday, May 21, 2025, with a mandatory pre-bid meeting and site inspection scheduled for Thursday, May 8, 2025, at 11:30 a.m. at 7029 Huron Road, Mackinac Island, Michigan. Questions are due by 2:00 p.m. Eastern time on Wednesday, May 14, 2025. Bidders must provide a lump sum base bid with a $30,000 allowance for unforeseen conditions, along with unit prices for rock excavation, modular retaining wall blocks (R-41, R-60, FS-T models), structural backfill, and earth excavation. Evaluation criteria include qualifications, past performance, technical approach, and proposed personnel, with the apparent low responsive bidder evaluated for responsibility and best value before contract award.

Michigan-based businesses or those demonstrating significant business presence in Michigan must be identified for reciprocity preference eligibility, and a Qualified Disabled Veteran (QDV) preference of ten percent is available to eligible service-disabled veteran-owned businesses that meet the requirement of 51 percent or more ownership by one or more veterans with service-connected disabilities. Bidders claiming SDVOB status must provide documentation including DD214 or equivalent proof of service and discharge conditions, proof of service-connected disability through DD214 or Veterans Administration Rating Decision Letter, and proof of business ownership, with the State accepting NVBDC certification as alternative verification. Michigan prevailing wage requirements apply to all work classifications with detailed wage schedules provided in the bidding documents. A five percent bid security is required, and performance and payment bonds are mandated for all contracts exceeding $50,000, with liquidated damages of $1,000 per calendar day assessed for delays beyond substantial completion and final completion dates. The contract structure includes a lump sum base with unit prices for contingent work; rock excavation quantities varying from anticipated amounts will be added or subtracted at the unit price, while other unit price variations will not result in adjustments unless unsuitable soils require deeper excavation as determined by the geotechnical engineer. The specific contract award value is not disclosed in the procurement documents, though the complexity and scope of the project, including two phases of work and contingency allowances, suggests a substantial public works contract.
