Lower Equestrian Campground Pit Latrine, Shimek State Forest, Lee County

The Iowa Department of Natural Resources is requesting bids for demolition, site preparation, and installation of a new prefabricated pit vault restroom building at the Lower Equestrian Campground in Shimek State Forest, Lee County, with bids due October 1, 2026 at 3:00 p.m. Electronic submission is required.

The scope encompasses demolition of existing pit latrines with vault pumping coordination, installation of an Iowa Wood Duck prefabricated modular restroom building (HuffCutt Concrete Inc. manufacturer), construction of a new ADA-compliant paved parking stall with reinforced concrete, minor grading, and site seeding. Work includes mobilization, 6-inch reinforced Portland cement concrete pavement on granular subbase (maximum 1.8% slope), yellow pavement markings, parking signage, and parking bumpers. Contractors must manage erosion control features including silt fencing and silt basins throughout construction and are responsible for identifying and avoiding damage to existing utilities. Site work must maximize distance from existing trees given proximity to stables. Contractors are required to conduct a pre-bid site visit to verify actual site conditions, dimensions, elevations, and existing underground utilities.

Project management is handled by the Iowa DNR with Morgan Nordyke as Project Manager and Bruce Flippin as Engineering Bureau Chief. Professional engineer Michael D. Dufoe (License No. 17753, valid through December 31, 2027) prepared the construction documents. The complete bid package, including detailed specifications, plans, and submission instructions, is available in the attached documents.
