The American Association of State Highway and Transportation Officials recently issued a brand new publication: “LRFD Steel Bridge Fabrication Specifications, 1st Edition.”

This new Load Resistance Factor Design or LRFD guide highlights the specifications governing the fabrication of vehicular steel bridges to include the furnishing and fabrication of steel structures, as well as the structural steel portions of other structures.
These new standards seek to achieve quality and value from a common specification that standardizes vehicular steel bridge fabrication in the United States, AASHTO noted.
Specifically, the specifications (a) minimize variations among projects; (b) provide economy, because individual fabricators would not have to change their methods and production variables; (c) allow expertise in steel bridge fabrication to be shared among states; and (d) enable owners to share resources, minimizing the effort each would, otherwise, spend to maintain their individual bridge fabrication specifications.
