1.4 Objectives

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.

Architectural, Structural, and Civil Engineering services will be required.

This request invites Respondents to submit a technical proposal and cost proposal for Phase 1 items identified under Section 4, as well as hourly rates for Phase 2 of the project.

At the completion of Phase 1, which requires providing a detailed report addressing each of the items outlined in Section 4, recommended repair solutions with a minimum design service life of 40 year with minimal maintenance and minor repair work needed under normal environmental conditions; and, at the sole discretion of the Department, the Department will make a determination on moving forward with services related to implementation of Phase 2, developing construction bid packages that efficiently repair the damage. Hourly rates provided by the Respondents will be used as a basis for contracting any additional design and oversight work to be completed as a part of Phase 2 of the tunnel repair project. The DNR will submit the Phase 1 report to the State Historical Preservation Office for review prior to making a determination on moving forward with services related to implementation of Phase 2.

As part of Phase 2, the selected firm will prepare final design in accordance with Iowa Department of Transportation Standard Specifications, including drawings, specifications and cost estimates. The firm will be responsible to coordinate the process with DNR, obtain all permits, perform needed survey (including any necessary topographic survey and wetland delineation), perform needed geotechnical services, prepare bid documents, develop addenda, answer pre-bid questions, conduct one onsite preconstruction meeting, conduct onsite construction inspection assistance at critical construction milestones, perform needed materials testing during construction, and will also be retained during construction for any clarifications from the DNR Field Engineer. The DNR will be responsible for NEPA Section 7 and Section 106 compliance (Archeological and/or SHPO coordination).

1.5 Background

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.

The project location maps can be seen in Attachment #1. Photos of the current conditions can be seen in Attachment #2.

4.1 Description of Statement of Work

Respondent is to provide a complete design for the necessary repairs of the Harmon Tunnel at Pammel State Park. The repair work should have a minimum design service life of 40 year with minimal maintenance and minor repair work needed under normal environmental conditions.

Construction staking will be the responsibility of the construction contractor.

Construction will occur between December 2026 and August 2027 to accommodate tree clearing and not impact visitors during the Covered Bridge Festival. The tunnel shall remain open as much as possible.

The Respondent shall meet on-site with the DNR to establish goals, objectives, and standards including but not limited to expectations, regulatory requirements, timelines, and communication protocols.

Phase 1 Through coordination with Iowa DNR staff and independent testing and analysis, the Respondent shall assess each of the following tunnel features in need of repair, and provide recommendations for improvement, removal, or replacement in a Phase 1 Analysis Report to be provided to the Iowa DNR Engineering Department:

1. Architectural fascia stone veneer archways over tunnel entrances - Currently, stone is separating from tunnel vault structure behind. Historical construction attached these stones to supporting structures using mortar. Assessment is needed by qualified engineer to determine whether stones can be re-anchored to structure behind, or if replacing the stones with similar new stones and modern anchoring system is a more practical and durable solution. Include recommendations for repair or replacement in Phase 1 assessment report and provide estimated service life after recommended repairs have been completed. Also provide recommended inspection and maintenance procedures in the report.

2. Limestone pieces accumulating at entrance pilasters and at ledges above tunnel entrances - Limestone accumulating in these areas appears to be falling from natural limestone bluff above.

Assess the natural limestone bluff for safety concerns including the possibility of larger sections of bluff falling into the roadway. In Phase 1 assessment report, provide recommended design solutions to mitigate limestone deterioration, detachment, and accumulation. Design solutions shall minimally impact the natural and architectural character of the tunnel and limestone bluff.

Also provide recommended inspection and maintenance procedures in the report.

3. Entrance portal limestone 'wing' walls each side of tunnel (4 total) - Each of the wing walls presents different design challenges. Assess each wall individually for structural integrity and stability, damage caused by vegetation, risk of future damage from vegetation, and general extent of each wall's deterioration. Include recommendations for repair or replacement of each section of wall in Phase 1 assessment report and provide estimated service life after recommended repairs have been completed. Also provide recommended inspection and maintenance procedures in the report.

4. Architectural limestone walls above archways - A small stacked limestone retaining wall above the archway on each side of the tunnel needs to be inspected and assessed for safety.

Determine whether the structural integrity of the wall is weak or weakening and what level of risk there is for stones falling into roadway or walls toppling.

Refer to the Iowa DOT Inspection Report attached to this RFP and provide any condition discrepancies in Phase 1 assessment report. Also provide recommendations for replacement or repair, and maintenance recommendations in report.

6. Repairs of stone pilasters at each entrance (4 total) - Assess condition of each pilaster tower paying particular attention to areas where walls, archways, or earth abut pilasters.

Include recommendations for repair or replacement of pilaster stone in Phase 1 assessment report and provide estimated service life after recommended repairs have been completed. Design solutions shall minimally impact the natural and architectural character of the historical pilasters. Also provide recommended inspection and maintenance procedures in the report.

7. Inspect concrete retaining wall each side of west end tunnel entrance for any cracks or spalled areas needing repair. Inspect areas where joint sealants are needed or are in need of repair.

Include recommendations for repair or replacement of concrete retaining walls in Phase 1 assessment report and provide estimated service life after recommended repairs or replacements have been completed. Also provide recommended inspection and maintenance procedures in the report.

8. Inspect concrete walkway at Southeast wingwall for unevenness, cracking, and usability. In the Phase 1 assessment report, state reasons for walkway deterioration and propose remedies for replacement or repairs. This may include modifying grade slopes and earthwork near sidewalks. Inspect areas where joint sealants are needed or where they are in need of repair.

Also provide recommended inspection and maintenance procedures in the report.

The design intent for this project is to provide the state with a completed tunnel repairs project that will extend the expected service life of the tunnel 40 years. Provide design and maintenance recommendations with this timeframe as an expectation, or provide evidence by precedent and commentary substantiating a reduced service life expectation.
