Board accepts Cedar Wapsi Road bridge rehab, authorizes $30,000 final payment
Summary
Supervisors accepted final completion for the Cedar Wapsi Road bridge replacement project, approved final payment of $30,000 (retainage) to Kramer and Associates, and recorded a total project cost of $1,060,395.20 with about a 1% overrun, county engineer said.
The Black Hawk County Board of Supervisors accepted the completed rehabilitation of Cedar Wapsi Road bridge over Craig Creek on May 6 and authorized final payment, releasing $30,000 in retainage to contractor Kramer and Associates.
Cathy Nicholas, Black Hawk County Engineer, presented before-and-after photos and described the work: replacement of the deck on the 75-foot, three-span bridge built in 1966, moving an expansion joint to reduce saltwater infiltration, upgrading guardrail to current standards, installing flumes to direct runoff and repainting exterior beams with a three‑part epoxy system. Nicholas told the board the project was completed in "substantial conformance with Iowa DOT standards" and that Kramer and Associates finished with about a 1% cost overrun.
The board recorded a total project cost of $1,060,395.20 and authorized the auditor to issue the $30,000 final payment. During the presentation, Nicholas noted the deck had been rated poor in prior inspections and showed delaminated spots that warranted replacement; she also said the new steel is epoxy coated to resist corrosion.
Why it matters: the acceptance closes the contract, releases retainage to the contractor and documents the county's compliance with Iowa Department of Transportation standards for bridge rehabilitation. That preserves the roadway and reduces future maintenance and public‑safety risk.
Details and next steps: the engineer recommended acceptance and release of retainage; staff will record final documents and release payment. The engineer estimated the new deck should last "30 to 40" (units not specified in the transcript) and noted routine DOT curing and inspection steps were followed.
