About this file
This is a Request for Proposal (RFP) issued by the Iowa Department of Natural Resources (DNR) for architectural and engineering services to design repairs for the Harmon Tunnel at Pammel State Park in Madison County. The project seeks a qualified Architectural, Engineering, and Construction (AEC) firm to address the architectural stone façade and retaining walls of the tunnel, which is considered Iowa's sole vehicular highway tunnel. The RFP was released on 20 August 2025, with proposals due by 17 September 2025 at 4:00 PM CDT under solicitation number 25CRDLWBMALDR-002.
The primary objective is to preserve the historical significance of the tunnel, which was originally hand-dug by a mill operator and his sons and later widened by Civilian Conservation Corps veterans in the 1930s. The project emphasizes minimal demolition and material removal, with a preference for reusing salvageable existing materials. All proposed repair work will require review by the State Historic Preservation Office (SHPO) for compliance with Secretary of the Interior Standards for Rehabilitation. The contract will be awarded in US Dollars, and interested parties can find additional contract terms and conditions on the Iowa DNR website.

Objective: The DNR Seeks to Purchase: Architectural and Engineering services from a qualified AEC firm for the design of the repair of architectural stone façade and retaining walls for Harmon Tunnel at Pammel State Park in Madison County.
Background information: Harmon Tunnel is a main feature of the Pammel State Park. Originally hand-dug by a mill operator and his two sons, it was widened for passage of vehicular traffic by the Civilian Conservation Corps (CCC) in the 1930's by WWI veterans. It is considered Iowa's sole vehicular highway tunnel.
Preserving the historical significance and architectural character of the Harmon Tunnel structure is an essential part of this project. Every attempt to make repairs to the existing structure and materials without undue demolition or material removal should be made. For areas of the tunnel found to be structurally unstable or unsafe, repair solutions should favor reuse of salvageable existing materials.
Where such solutions are not feasible or practical, proposed repair work must be substantiated and approved. All proposed work will undergo review by the State Historic Preservation Office (SHPO) for compliance with Secretary of the Interior (SOI) Standards for Rehabilitation.
