FY27 NW St. Joseph Salt Dome Roof Replacement Project

The Missouri Department of Transportation (MoDOT) is soliciting bids through an Invitation for Bid for the FY27 NW St. Joseph Salt Dome Roof Replacement Project, with a mandatory site visit due by November 13, 2026 and bids closing November 24, 2026. Attendance at the site visit is required for any bid to be accepted. The solicitation sets no set-aside, though M/WBE and Service-Disabled Veteran Business participation is encouraged.

The scope covers two salt dome structures at the NW District St. Joseph Maintenance facility: Building L (approximately 82 feet in diameter) and Building M (approximately 100 feet in diameter). The contractor must remove existing polyurethane foam roofing, three-tab shingles, felt underlayment, vents, flashing, and entrance fascia down to decking. It must then install 30-year or greater manufactured warrantied composite architectural shingles, ice and water barrier, synthetic underlayment, galvanized flashing, and 750 metal roof vents. Additional work includes replacing up to 30 sheets of roof sheathing and installing entrance rafters. Bids are itemized on three lines: Building L, Building M, and damaged sheathing priced per sheet. The contract is structured as a Blanket Purchase Agreement. The project completion date is May 18, 2027, including 15 days for submittals.

Bidders must post a bid guaranty of 5 percent of the bid amount and furnish a performance and payment bond equal to 100 percent of the contract price within 15 calendar days of contract transmission. Prevailing wage rules under Chapter 290 RSMo apply in Buchanan County, with a penalty of $100 per day per worker for non-compliance. The contractor must self-perform at least 10 percent of the work and submit a subcontractor list for any portion exceeding one percent. OSHA 10-hour construction training is mandatory for all on-site employees. Liquidated damages are $500 per day per item for delivery delays. Insurance requirements include general liability of $600,000 per person and $4,000,000 aggregate, plus Missouri workers' compensation with $1,000,000 employer's liability coverage.

Written questions are due November 16, 2026, and addenda will post by November 17, 2026. Hard-copy bids require notice to the buyer of record, Logan Wilbers (logan.wilbers@modot.mo.gov), five business days before bid closing. Bids are submitted electronically through MissouriBUYS or by mail, UPS, or FedEx.
