Summary

This is a Scope of Work and Specification document issued by the Iowa Department of Transportation (Iowa DOT) for RFB 2497, which involves the installation of a new 120-foot by 15-inch diameter tile crossing under US Highway 59 at Station 494+51 (Reference Post 208.32) in Osceola County, District 3. The project requires the contractor to supply all labor, materials, and equipment to install the tile crossing, with the section beneath the highway to be completed via trenchless construction meeting Iowa DOT Standard Specifications for Highway and Bridge Construction (2015 series) with GS-15011 supplemental specifications, while the balance may utilize open trench construction. The tile must be connected to existing tile infrastructure per Standard Road Plan DR-122, with inspection access installed per Standard Road Plan DR-302. Materials must comply with restrained joint ductile iron pipe, restrained joint PVC pipe, or casing pipe with minimum 0.375-inch wall thickness. The project is funded through the Emergency and Contingency program under Project Code NHSN-059-9(024)--2R-72 and Work Code 3542-Subdrains. The bid was posted February 11, 2026, with responses due February 13, 2026, allowing a two-day submission window. Completion of the utility installation must include as-built plans submitted to the district representative within 90 days of construction completion, with all work to be finished within one year of permit approval.

Traffic control must comply with the Manual on Uniform Traffic Control Devices (MUTCD) and Iowa DOT standards TC-1, TC-202, and TC-213, with no equipment or personnel permitted in the traveled roadway unless lanes are closed. All personnel in the right-of-way must wear ANSI 107 Class 2 high visibility apparel, and work hours are restricted to 30 minutes after sunrise through 30 minutes before sunset unless otherwise specified. The permit holder must contact Iowa One-Call 48 hours before excavation and provide 48-hour advance notice to the DOT representative before construction begins. The utility permit (U2026-72-2-1) was approved with an expiration date of January 7, 2027, and the permit holder is responsible for obtaining any necessary easements from the drainage district and complying with all local, county, state, and federal regulations. No specific contract value, set-asides, or incumbent vendor information is disclosed in the documentation. All disturbed areas must be restored to original condition with appropriate seeding using specified seed mixture for rural areas, and all appurtenances must be marked with permanent high-visibility posts and signs with minimum 5-foot height requirements.
