751/24168. ABG; Historic Mill Creek Visitor Center

The State of Michigan Department of Technology, Management and Budget (DTMB) is soliciting competitive sealed bids for the renovation and rehabilitation of the Historic Mill Creek Visitor Center located at 9001 W. US-23 in Mackinaw City, Michigan. The procurement addresses comprehensive construction work on two existing unheated, uninsulated buildings—a visitor center facility (approximately 3,800 square feet) and an associated restroom/pavilion structure—that currently operate seasonally during summer months. The scope of work includes adding insulation to roofs and walls where the exterior envelope is altered, installing new mechanical heating and ventilation systems for each building, and extensive interior and structural renovations in compliance with the 2015 Michigan Rehabilitation Code and ADA/ICC A117.1 accessibility requirements. Deliverables encompass architectural, structural, civil, mechanical, plumbing, and electrical work, including installation of structural insulated panels for roof assembly with standing seam metal roofing, interior finishes with ceramic tile and polished cementitious overlays, new rooftop HVAC units with energy recovery ventilation, sensor-operated plumbing fixtures, and 400-amp electrical service panels. Qualified bidders must hold appropriate Michigan licenses for general construction, mechanical, plumbing, and electrical trades, comply with Michigan prevailing wage requirements, maintain 50% Michigan resident employment for at least one year prior to employment, and provide evidence of capability to manage hazardous materials abatement and Department of Natural Resources site-specific restrictions. A mandatory prebid conference was held on December 18, 2024, at 11:00 a.m. at the project site, with questions accepted through January 8, 2025, at 2:00 p.m. Eastern time directed to Tracie Williams (tracie.williams@ohm-advisors.com) or the project architect OHM Advisors (taylor.nettell@ohm-advisors.com or 906-482-0535). Sealed bids are due electronically through the SIGMA VSS procurement portal on January 15, 2025, at 2:00 p.m. Eastern time, with a maximum of two attachments each not exceeding 25 megabytes. The contract specifies Substantial Completion by March 18, 2026, and final completion by April 15, 2026, with liquidated damages of $1,000.00 per calendar day for schedule delays.

The contract imposes no specific set-aside designations for disadvantaged enterprises based on the available documentation, though all contractors must meet state residency mandates requiring 50% Michigan resident workforce. All bidders must submit a 5% bid security, and contractors awarded contracts exceeding $50,000 must provide performance and payment bonds along with builders risk insurance prior to contract execution. The project is funded by the State of Michigan with support from Mackinac State Historic Parks, though specific budget allocations or award values are not disclosed in the procurement documents. No incumbent vendors or existing contracts are referenced, as this represents new construction procurement. Bidding documents, including detailed 100% construction documents, specifications, and Addendum No. 1 (issued January 9, 2025), are available through the SIGMA procurement portal at https://sigma.michigan.gov/webapp/PRDVSS2X1/AltSelfService. Key addendum modifications include removal of December 1 through April 1 work restrictions, clarified product specifications for flooring systems, weather barriers compliant with ASTM E2556 standards, and standing seam metal roof panels by ATAS International or approved equivalents.
