These are architectural construction documents for a roof replacement project for the Iowa Mental Health Institute (IMHI) storage building, prepared by Horizon Architecture for the Iowa Department of Administrative Services (DAS). The project involves a comprehensive roof replacement for a storage barn/building located in Independence, Iowa, with specific details including complete removal of existing roofing materials, replacement of roof decking as needed, installation of new asphalt shingles, ice and water shield, underlayment, flashing, and associated roofing components. The project number is DAS 9247.00, and the documents are issued for permit and construction as of October 11, 2022.

The project specifications indicate a repair/replacement classification under the 2015 International Existing Building Code (IEBC), with the primary goal of maintaining the building's existing structural and performance requirements. Design criteria include an ultimate wind speed of 115 MPH and Exposure B conditions. The construction will be managed by Boyd Jones, with the owner represented by the Iowa Department of Administrative Services. Key technical details include replacing wood shingles, assessing and replacing roof underlayment, installing new drip edges, step flashing around cupolas, and ensuring proper water management through valley and ridge detailing. The documents provide comprehensive technical drawings, demolition plans, elevation views, and specific roofing installation details to guide the construction process.
