The Iowa Department of Natural Resources (DNR) is soliciting bids for the Conservation Discovery Area project at the DNR Fairgrounds in Polk County. This procurement is a capital improvement contract (Project #24-05-77-02) for constructing an interpretive cave and stone tower within the DNR Building on the Iowa State Fairgrounds. The project involves creating a detailed artificial rockwork environment using shotcrete techniques, with specifications requiring a realistic representation of Maquoketa Caves and Pilot Knob State Park. Contractors must demonstrate extensive experience in naturalistic simulated rock construction, with proof of at least three comparable completed projects. Bidders are required to submit detailed proposals electronically to constructionbids@dnr.iowa.gov by January 23, 2025, at 3:00 PM CST, with the project completion date set for July 15, 2025. The project includes base bid items for mobilization, demolition, and cave/tower structure construction, as well as an alternate bid item for interpretive features. Technical requirements mandate specific construction techniques, including low relief carving, rock wall formations, and specialized staining and painting to achieve a realistic cave environment.
The contract does not explicitly outline specific set-aside designations for disadvantaged enterprises, though it does include a preference for products grown and coal produced within Iowa. Contractors must provide a performance bond of 100% of the contract price for contracts exceeding $25,000 and maintain public liability insurance of $250,000 per person and $500,000 per occurrence, with property damage insurance of $250,000 per occurrence. The project requires an NPDES Stormwater Discharge Permit for any land-disturbing activity over one acre. Liquidated damages of $1,000 per day will be assessed for work extending beyond the completion date. While specific budget ranges are not explicitly stated, the detailed specifications and complex construction requirements suggest a significant capital investment. The contract allows for proposal validity for 45 days after submission and requires contractors to meet stringent technical specifications, including shotcrete compression strength of 4000 psi at 28 days and the use of high-quality architectural stone products like Eldorado Stone LLC's Country Rubble - Polermo.
