NE District Hannibal Salt Dome Roof Restoration Project

The Missouri Department of Transportation (MoDOT) has issued an Invitation for Bid (IFB) for the NE District Hannibal Salt Dome Roof Restoration Project, seeking a qualified roofing contractor to fully restore the roof of a salt dome structure located in Hannibal, Missouri. The project requires comprehensive roof replacement, including removing existing three-tab shingles, felt underlayment, approximately 20 roof vents, and flashing, and replacing them with 30-year or greater manufactured warranted composite architectural shingles, synthetic underlayment, galvanized flashing, and 750 metal roof vents. The salt dome structure, approximately 90 feet in diameter with a 6-foot concrete wall and 50-foot overall height, is divided into 20 sections. Bidders must also be prepared to remove and replace up to five sheets of 7/16" CDX sheathing, with additional sheets priced separately if needed. The bid submission deadline is November 1, 2022, at 2:00 PM CDT, with a project completion date of May 24, 2023. Site visits can be scheduled by contacting the MoDOT inspector, and contractors are expected to provide a detailed bid that includes all necessary permits and licenses.

MoDOT strongly encourages Minority Business Enterprise (MBE) and Women Business Enterprise (WBE) participation, with specific goals of 10% MBE and 5% WBE involvement through subcontractors, suppliers, or joint ventures. Bidders must provide a bid bond or equivalent for 5% of the bid amount and, upon contract award, a 100% performance and payment bond. The project is subject to prevailing wage requirements under Annual Wage Order #29 for Marion County and requires contractors to carry specific insurance coverage, including $500,000/$4,000,000 in general and automobile liability. While no specific budget range is explicitly stated, the contract will be awarded to the lowest responsive and responsible bidder, with liquidated damages of $500 per day assessed for late completion. Contractors must demonstrate quality management oversight, as MoDOT will not provide daily inspection, and must comply with the state's employment verification and anti-discrimination regulations. The project also includes a one-year warranty requirement for all materials and labor.
