About this file
This is a specification document for the FY27 Kansas City Richmond Salt Dome Roof Replacement Project administered by the Missouri Department of Transportation (MoDOT). The project requires removal of existing polyurethane foam roofing, three-tab shingles, felt underlayment, roof vents (20+/-), flashing, and entrance fascia down to decking, with installation of 30-year or greater manufactured warranty composite architectural shingles, synthetic underlayment, galvanized flashing, and 750 metal roof vents to create a complete and watertight roof system. The specifications establish comprehensive general requirements including contract administration procedures, submittal protocols, quality control standards, construction facilities and temporary controls, material and equipment handling, system startup procedures, and contract closeout requirements. Specific product specifications are detailed for wood framing and sheathing (Division 6), asphalt shingles (Division 7), weather barriers, metal roof and wall panels, flashing and sheet metal work, and joint sealers. Bids are accepted electronically through MissouriBUYS, by mail, UPS, or FedEx, with contractors required to contact buyer Logan Wilbers at logan.wilbers@modot.mo.gov at least five business days prior to bid closing if submitting hard copy proposals. Site visit attendance is mandatory for bids to be accepted.
The specifications establish standard contracting terms requiring contractors to submit schedules of values within 20 days of the Owner-Contractor Agreement, applications for payment with 30-day payment periods, and certified payroll records. Change order procedures allow for both architect-issued notices of change and contractor-proposed changes using stipulated sum, construction change directive, or time and material methods. Quality assurance requirements mandate compliance with manufacturers' instructions and specified industry standards, with testing and inspection services provided by MoDOT personnel. Contractors are responsible for all temporary electricity, telephone service, facsimile service, water service, sanitary facilities, security, fencing, and protection of installed work. Contract closeout requires final cleaning, project record documents, operation and maintenance manuals in three-ring binders, spare parts delivery, and execution of transferable warranties. Projects shall not be accepted until all punch list items are completed, with vendors having 30 days to submit required closeout paperwork or face potential debarment or suspension from future MoDOT projects.
