Cabin Window Replacement REBID, Lake of Three Fires, Taylor County

The Iowa Department of Natural Resources is issuing a competitive quotation for a minor public improvement contract to replace all windows on six historically significant cabins at Lake of Three Fires State Park in Taylor County. The project involves replacing 36 total window units across the six cabins, including 24 single-hung operable windows (Window A, approximately 30x46 inches with replicating muntins), 6 picture windows (Window B, approximately 32x24 inches), and 6 privacy picture windows (Window C, approximately 28x32 inches). Deliverables include removal of existing windows, inspection and repair of head, jamb, and sill framing for rot and damage, installation of manufacturer-approved flashings, concealed spray foam insulation, and matching of new interior and exterior trim to existing specifications. New windows must be factory-fabricated wood units from approved manufacturers including Pella Corporation, Marvin Windows, Quaker Window Products, Lincoln Windows, or Kolbe Windows, meeting Performance Class R with a Performance Grade of 30, maximum U-value of 0.35, double-glazed Low-E coated argon-filled glass, and acoustic performance rating of at least 38 OITC. Contractors must submit shop drawings and manufacturer certificates for DNR Field Engineer review prior to ordering windows and provide evidence of AAMA, WDMA, or CSA certification, with both manufacturer and installer demonstrating at least three years of documented experience. Electronic proposals must be submitted to constructionbids@dnr.iowa.gov by 3:00 PM on Thursday, February 26, 2026, with project completion required by June 11, 2026. Work is restricted to Monday through Thursday only, with no work permitted May 25-28 or on weekends, and all windows must be completed by end of business Thursday to avoid disrupting public cabin usage.
