Collins was retained by Genesee & Wyoming to provide inspection and load rating services for steel bridges on the Rapid City, Pierre & Eastern Railroad, the majority of which are located in South Dakota in G&W’s Mountain West region.
The project included 134 steel bridges of various types, including truss, through-plate girder, deck-plate girder, and rolled beam span bridges. Collins provided the following services:
- Inspection of all steel structures to document current configurations and to identify conditions that affect the safe passage of trains.
- Structural analysis and application of the applicable AREMA Standards to determine the safe design and operating capacity of each inspected structure.
- Documentation of the findings.
The objective of the project is to ensure compliance with the USDOT’s Federal Railroad Administration Bridge Safety Standards as described in 49 CFR Part 237 of the Code of Federal Regulations and Transport Canada’s Guidelines for Bridge Safety Management.
