Benton County commissioners approved contracts with a consultant to provide construction inspection services for two federally funded bridge replacement projects, while staff and commissioners discussed the trade‑offs between outsourcing inspections and building in‑house inspection capacity.
County staff presented two federally funded bridge replacement projects: one on County Road 22 over the west branch of the Rum River and one on County Road 51 over the St. Francis River. The county received federal bridge replacement funds covering roughly half of total project costs. The recommended consultant, which designed the bridges, submitted lower inspection bids; staff reported inspection fee estimates of about $126,560 for one structure and about $130,340 for the other (combined inspection costs roughly $256,900). The construction timeline included multiple weeks of on‑site observation; one consultant estimate included about 724 hours of construction‑observation work (roughly 12–18 weeks full‑time depending on weekly hours).
County staff and commissioners discussed that the current county workforce lacks certified bridge‑construction inspectors, and that certified bridge inspection (including MnDOT‑recognized proficiency) can take multiple years of field experience to achieve. Several commissioners and staff framed the contract decision as the immediate practical option while also noting the longer‑term case for hiring and training in‑house inspectors to reduce recurring consultant costs.
The board moved, seconded and approved the recommended contracts. Staff said the projects were budgeted for 2025 and that subsequent bridge replacements are anticipated in coming years, reinforcing the need for planning around long‑term inspection capacity.
Why it matters: Bridge inspection and construction oversight are technically specialized and time‑sensitive; the board’s approval allows the county to proceed with federally funded bridge replacements this construction season but also raised questions about workforce strategy and long‑term county capacity to perform inspections.
