The Oregon Department of Transportation (ODOT) is requesting bids for metal roof replacement at the McKenzie Bridge Maintenance Station, with bids due October 20, 2026 and mandatory pre-bid site visit required prior to submission.

The scope covers complete removal and replacement of the existing metal roof system on a 5,100 square foot maintenance building at 56377 N Bank Road, McKenzie Bridge, Oregon.

Panels must be five inches thick, 40 inches wide, with 24-gauge AZ50/Galvalume exterior and interior faces and polyisocyanurate foam core (minimum 2.1–2.5 pcf density). The basis of design specifies Kingspan KingSeam roof panels; alternates require prior written approval from the ODOT Construction Project Manager, Austin Van Nette (Austin.VAN_NETTE@odot.oregon.gov, 503.507.1394). Work must conform to Oregon Structural Specialty Code Chapter 15 Section 1512 re-roofing requirements and multiple technical standards (ASTM, AAMA, ASCE, IBC, Factory Mutual). Gutters must be pre-finished aluminum, six-inch facia style, with KYNAR 500/HYLAR 5000 coating. The contractor must obtain all required local building permits, conduct a comprehensive pre-work visual inspection, and perform work Monday through Friday, 0700 to 1700, unless otherwise approved. Warranties include two-year manufacturer coverage on materials and workmanship and twenty-year panel-finish warranty from Substantial Completion.

The estimated contract value ranges from $75,000 to $150,000. All bids must be sealed and submitted by the stated deadline. ODOT reserves the right to reject any or all bids and reserves award discretion based on quality, timeline, and other factors beyond price. The contractor must maintain current licensing, bonding, and insurance appropriate to the work scope and comply with prevailing wage requirements under Oregon Revised Statutes.
