Abstract

Over the past 6 years, the Federal Highway Administration (FHWA) Office of Bridge Technology has been working with other government agencies and industry groups to speed the fabrication and repair of bridges, while simultaneously reducing the costs. This is a report of their activity A review of innovations in other countries identified a number of areas of automation that seemed appropriate for steel bridge applications in this country. These were developed further in a three-day workshop in 2001 at the Edison Welding Institute (EWI) in Columbus, Ohio. The workshop was sponsored by FHWA and the National Steel Bridge Alliance (a cooperative effort to improve the steel bridge design and construction, and a part of AISC). The workshop was cosponsored by the American Association of State Highway and Transportation Officials, EWI, and NIST. Since the workshop, these ideas are being driven by a team under the leadership of the FHWA. The current plan is to demonstrate the effectiveness of the workshop idea during the fabrication of two similar bridges, one using current technology and one which advanced technology. The fabrication of both bridges will be carefully documented.
