751/18140. SMD Belle Isle Conservatory - Steel Truss Replace

The State of Michigan, through the Department of Technology, Management and Budget (DTMB) and the State Facilities Administration, Design & Construction Division, is soliciting construction bids for the Belle Isle Conservatory Steel Truss Replacement project located at 900 Inselruhe Avenue, Detroit, Michigan 48207 (DTMB File Number 751/18140.SMD). The scope of work encompasses the replacement of lower steel truss columns throughout the Conservatory's central dome (Palm House), removal of lead-based paint from existing steel to remain, provision of new galvanized steel truss columns and gusset plates, repair of cast iron gutters, temporary shoring and support systems for windows, installation of negative air management systems for dust and odor control, asbestos abatement, and limited painting of repair areas. Deliverables include engineered shoring drawings, temporary utility specifications, material schedules, subcontractor lists, and compliance documentation for fire prevention, lead-based paint abatement, historic building procedures, and prevailing wage requirements. Key objectives include completing structural repairs within 180 calendar days for substantial completion and 210 calendar days for final completion from the Notice to Proceed, with liquidated damages assessed at $1,000 per calendar day for delays. A mandatory pre-bid conference and site tour was held on June 7, 2018, at 10:00 AM; bidders were required to submit electronic bids through the SIGMA VSS website by 2:00 PM on July 3, 2018 (extended from June 20, 2018, via addenda). Qualified bidders must demonstrate experience with similar projects, provide references, submit 5% bid security, and maintain on-site superintendents and fire safety managers throughout the contract duration.

The procurement documents do not identify specific set-asides for disadvantaged enterprises or restrictions limiting bidder eligibility; however, prevailing wage documentation is required and Performance and Payment Bonds are mandatory for contracts exceeding $50,000. No incumbent vendors or current contractors are identified in the available documentation. The project requires integration with existing Belle Isle infrastructure, including coordination with State personnel regarding plant modifications, protection of surrounding plant life, and temporary heating provisions for the removal and reinstallation of Fin Tube Radiators. Apparent low bidders were required to submit qualification submittals by 10:00 AM on July 6, 2018, including bid breakdowns, subcontractor lists, and pre-award schedules; the State Administration Board was scheduled to review the award on July 31, 2018, with contract receipt anticipated within two weeks of that meeting. While a specific budget or award value is not stated in the available documents, the project scope and six-month timeline indicate a substantial construction contract requiring experienced structural steel contractors with expertise in historic building restoration, hazardous materials abatement, and complex temporary construction systems.
