About this file
This construction document set, prepared by the Iowa Department of Natural Resources (DNR) Engineering Section, details the plans and specifications for the Lower Equestrian Campground Pit Latrine project at Shimek State Forest in Lee County, Iowa (Project No. 27-06-56-01). The project scope includes demolition of existing pit latrines, installation of a prefabricated modular restroom building (Iowa Wood Duck model manufactured by HuffCutt Concrete Inc.), construction of a new ADA-compliant paved parking stall with reinforced concrete, minor grading, and site restoration with seeding. Key work items include mobilization, removal and disposal of existing facilities with coordination of vault pumping, placement of 6-inch reinforced Portland cement concrete (PCC) pavement on granular subbase with a maximum 1.8% slope, yellow pavement markings, installation of a 15-minute parking sign, and parking bumper installation. The bid closing date is October 1, 2026, at 3:00 PM, with electronic submission required. Contractors are required to visit the project site prior to bidding to verify actual site conditions, dimensions, and elevations, and to familiarize themselves with existing underground utilities and facilities.
The plans specify that all work shall conform to applicable codes and ordinances, with the contractor responsible for identifying and avoiding damage to existing utilities and for providing disposal sites for excess excavated material and broken concrete. The contractor must manage erosion control features including silt fencing, seeding, and silt basins throughout construction. Site conditions show proximity to existing stables and require maximization of distance from existing trees. The project is supervised 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, prepared these construction documents with a license renewal date of December 31, 2027. No pricing information, funding sources, or set-aside provisions are detailed within this plans document.
