This is a Scope of Work document prepared by the Iowa Department of Natural Resources (DNR) Engineering Section for a roadway patching project at Springbrook State Park in Guthrie County. The project involves Hot Mix Asphalt (HMA) full depth road patches within the campground area, comprising five distinct patches with a combined total of 129.9 square yards. Patch #1 measures 91.1 square yards, Patch #2 measures 2.0 square yards, Patch #3 measures 5.3 square yards, Patch #4 measures 6.1 square yards, and Patch #5 measures 25.4 square yards. The work includes removal of existing HMA pavement (assumed 6 inches thick), placement of IDOT Special Backfill as necessary to level the subgrade, and installation of new HMA patches. The bid date is December 11, 2025, and proposals must be submitted electronically to constructionbids@dnr.iowa.gov by 3:00 PM CST. Contractors are required to visit the project site prior to bidding to verify actual locations, elevations, and job conditions. No work is permitted from Friday at noon until sunrise Monday. The contractor bears responsibility for site restoration, traffic control, waste disposal, utility verification, and erosion control measures including seeding, silt fence, and silt basins as needed.

The document specifies that bidders shall submit lump sum bids or clearly identified unit prices without alternates, qualifications, or reservations. The project manager is Zach Gunsolley (515.250.3713, zach.gunsolley@dnr.iowa.gov), and the procurement specialist is Darin Galbraith (515-344-0055, darin.galbraith@dnr.iowa.gov). The contractor must verify all dimensions and conditions at the site and notify the DNR Engineer of any discrepancies prior to proceeding with work. Contractor proposals remain valid for 45 days from the submission deadline. The DNR reserves the unconditional right not to award the contract and will notify both successful and unsuccessful bidders of results. The commodity codes associated with this project are 91395 (Paving and Resurfacing, Highway and Road) and 98800 (Roadside, Grounds, Recreational and Park Area Services), indicating the project is open to standard construction and road maintenance contractors. No specific budget amount, set-aside designations, or disadvantaged enterprise restrictions are detailed in the scope of work document.

General Information

1. Verify actual locations and elevations with DNR Engineer.

2. All work shall conform to and be performed in accordance with all applicable codes and ordinances.

3. The contractor shall visit the site and inspect the project area and thoroughly familiarize themselves with the actual job conditions prior to bidding and the start of work. Failure to visit the project site shall not relieve the contractor from performing the work in accordance to the plans, specification, special provisions and contract.

4. The contractor shall verify, at the site, all dimensions and conditions shown on the plans and shall notify the DNR Engineer of any discrepancies, omissions, and/or conflicts prior to proceeding with the work.

5. It shall be the contractor’s responsibility to provide waste areas or disposal sites for excess material (excavated material or broken concrete) which is not desirable to be incorporated into the work involved on this project. No payment for overhaul will be allowed for material hauled to these sites. No material shall be placed within the right-of-way, unless specifically stated in the plans or approved by the DNR Engineer.

6. The contractor shall not disturb desirable grass areas and desirable trees outside the construction limits. The contractor will not be permitted to park or service vehicles and equipment or use these areas for storage of materials. Storage, parking and service areas will be subject to the approval of the DNR Engineer.

7. Where utilities and fixtures are shown as Existing on the plans or encountered within the construction area, it shall be the responsibility of the contractor to notify the DNR Engineer of those utilities prior to the beginning of any construction. The contractor shall be afforded access to these facilities for necessary modification of services. Underground facilities, structures and utilities have been plotted from available surveys and records and therefore their locations must be considered approximate only.

It is possible there may be others, the existence of which is presently not known or shown. It is the contractor’s responsibility to determine their existence and exact location and to avoid damage thereto. No claims for additional compensation will be allowed to the contractor for any interference or delay caused by such work.

8. The contractor shall shape graded area to maintain surface drainage. All elevations are to finish grade.

9. The contractor is expected to have materials, equipment, and labor available on a daily basis to install and maintain erosion control features on the project. This may involve seeding, silt fence, rock ditch checks, silt basins or silt dikes.

10. No work allowed from Friday at noon until sunrise Monday.
