Specifications include, but are not limited to: MnDOT requests responses for Bridge Office and State Aid for Local Transportation (SALT) Group have identified county and local bridges as susceptible to supporting Specialized Hauling Vehicles (SHV), Electric Vehicle (EV) and now Implements of Husbandry (IoH) vehicles. Some bridges may require posting for SHV and EV vehicles (posting limits specified in online EV mapping tool), but no specific posting guidance has been formalized for IoH vehicles to date. Hence, the final bridge list for evaluation in this contract will also include load rating for IoH. The list of bridges for IoH load rating was based on current operating ratings, IoH notional load, bridge type and rating method. Work under this Contract involves rating and load posting analysis of bridges on the State’s local system. Services include new rating analysis, recommendations for posting at or below the legal load, when necessary, bridge field investigations to ensure rating accuracy and conformance with actual field conditions, examine current rating to ensure conformance with the new posting loads,
