About this file

Written by GovTribe AI · Dec 1, 2025

This file contains architectural drawings for the Iowa Department of Administrative Services (DAS) Water Infiltration Mitigation project at the DPS P08 facility in Mason City, Iowa. The project involves comprehensive roof and attic demolition and restoration work designed to address water infiltration issues. Key demolition tasks include removal of existing roof shingles and sheathing, brick, metal flashing, metal panels, gypsum wall board, insulation, electrical boxes, valley flashing, wall base, and carpet. The scope requires careful examination of existing conditions prior to bidding, with contractors responsible for infilling and patching any openings, repairing damaged surfaces, and preparing substrates for new finishes. Installation of new materials includes spray foam insulation with a minimum R-value of 30, asphalt shingles, metal roof components, ice and water shields, metal fascia and soffit, roof valley flashing, deicing cables, and related finishes. The project is scheduled to commence May 5, 2025, and conclude by May 20, 2025. A pre-bid meeting is scheduled for February 26, 2025, at 10:30 AM at the project site with virtual attendance available. The bid opening occurs February 22, 2025, at 9:30 AM CST, with final bid submissions due March 11, 2025, at 2:00 PM CDT.

Bid security of 5 percent of the total bid amount is required via bid bond, cashier's check, or certified check from a U.S. bank. All submissions must be made through the IMPACS Electronic Procurement System using the specified bid form, with questions due by March 6, 2025. The project documentation is dated February 12, 2025, and available through Beeline and Blue. Targeted Small Business Enterprise participation is required, with bidders obligated to comply with state and federal affirmative action and equal employment opportunity provisions. The project is exempt from Iowa Sales Tax, and Davis Bacon Wages do not apply. Contractors must maintain weather-tight conditions throughout construction, protect and brace existing structures to maintain structural integrity, and coordinate with the architect regarding equipment placement and material reuse requirements.
