751/24226. SAA; Straits State Harbor - Solar Arrays

The State of Michigan Department of Technology, Management and Budget, State Facilities Administration, is soliciting a Design-Build Entity (DBE) through a design-build procurement method to provide comprehensive design and construction services for solar array installations at Straits State Harbor (409 S. Huron Street, Mackinaw City, Michigan) in Chippewa County. The project scope includes the placement, design, and construction of canopy-style steel structure panels oriented east-west along an existing sidewalk and ground-mounted solar panels on an existing island and North Pier, with the system sized to offset electrical usage across two meters at the facility. Key deliverables include topography surveys, soil borings, push-pull testing, 50% and 90% contract document reviews, coordination with the local utility company (Consumers Energy) for electrical interconnection, compliance with all applicable state and local codes including environmental and soil erosion standards, and attendance at twice-monthly progress meetings during construction. The DBE must provide a Not-To-Exceed bid structured across compensation categories of Design Services, Construction/Trade Labor/Subcontractors (which must include a $100,000 provisional allowance), General Conditions, Management, and Overhead and Profit as a percentage of subtotal. A mandatory pre-bid conference and site tour is scheduled for Thursday, September 4, 2025, at 9:00 a.m. Eastern Time at the project location. Sealed electronic bids must be submitted through the SIGMA website by Wednesday, September 24, 2025, at 2:00 p.m. Eastern Time (extended from the original September 17, 2025, deadline per Addendum 3). Contract completion is required within 180 calendar days from Notice-to-Proceed or by May 23, 2026, with liquidated damages of $500 per calendar day for delays beyond substantial completion. Evaluation criteria include responsiveness, responsibility, financial resources, technical capabilities, past performance, insurance and bonding capacity, and business integrity, with awards based on best value from the three lowest responsive and responsible bidders.

Bidders must comply with Michigan prevailing wage requirements and Michigan residency requirements (50% of employees must be Michigan residents). All bids exceeding $50,000 require performance and payment bonds, and a 5% bid guarantee is required at the time of bid submission. All bidders must provide proof of State Project Registration from the Department of Labor and Economic Opportunity and acknowledge all addenda (three addenda have been issued to date) in their bid submission, with failure to do so resulting in bid rejection. Electronic bid responses are limited to a maximum of two attachments, each under 25 megabytes. No incumbent vendors or specific set-aside designations for disadvantaged enterprises are identified in the procurement documents. The project requires integration with the existing electrical infrastructure at Straits State Harbor, as documented in the electrical plans and facility condition assessment (Phase 100 Report prepared by NTH Consultants, which evaluated the structural condition of shoreline structures, pavement systems, and associated facilities). The Phase 100 Report indicates that upon completion of recommended repairs, structures are expected to provide a 50-year remaining service life. No specific budget or award value is explicitly stated in the available documentation; however, the Phase 100 Report recommends structural rehabilitation costs ranging from approximately $2.9 million to maintain current use and $12.2 million for comprehensive community use improvements, which may inform bidders' understanding of the project's financial scope. State Administrative Board contract approval is anticipated for October 21, 2025, with the DBE expected to be under contract by November 2025.
