This legislation establishes new requirements for corrosion prevention and repair on federally funded bridge and railroad bridge projects. It mandates that critical aspects, such as surface preparation , coating application , and hazardous coating removal , must be carried out by certified contractors . These contractors are firms certified by recognized third-party organizations that assess their capability to perform specialized tasks, ensuring high-quality infrastructure work and adherence to industry standards. Entities undertaking these projects must implement a comprehensive corrosion management system , utilizing industry-recognized standards and methods. Certified contractors are also required to employ a substantial number of individuals trained and certified through qualified programs, and provide training for uncertified employees. The bill further expands federal grant eligibility to include corrosion control work on rail bridges and directs a study on best practices for inspecting and addressing corrosion on weathering steel bridges , with findings to be shared with transportation agencies.
