Solicitation 91-5587-607 is issued by the Iowa Department of Transportation for the construction of a Portland Cement Concrete sidewalk and ramps within the corporate limits of the City of Norwalk in Warren County. The scope of work includes installing ramps at Pine and Main, and constructing sidewalks on Pine, Center, and Elm streets. Key deliverables involve the installation of concrete pedestrian paths, accessible ramps, and the implementation of erosion control measures, including rurban seeding and sediment control devices. The project requires adherence to specific standard specifications and technical standards for PCC driveways, detectable warnings, and full depth patching with dowels. An addendum dated September 8, 2026, modified the proposal schedule of items by increasing the quantities for full-depth finish patches and subbase patches from 35.000 SY to 38.000 SY. The project documentation consists of 45 plan sheets covering typical sections, quantities, and plan profiles. The letting date and response deadline are set for September 15, 2026. Payment is based on plan quantities, and field measurements are not permitted without authorization from the Engineer. The contractor is responsible for providing certified plan inspection, although verification gradations are not required for this project.
