National Steel Bridge Alliance
The AASHTO/NSBA Steel Bridge Collaboration is a joint effort between the American Association of State Highway and Transportation Officials (AASHTO) and the National Steel Bridge Alliance (NSBA) with representatives from state departments of transportation, the Federal Highway Administration, academia, and various industry groups related to steel bridge design, fabrication and inspection. The mission of the Collaboration is to provide a forum where professionals can work together to improve and achieve the quality and value of steel bridges through standardization of design, fabrication and erection.
Guide Specification "S" Documents
Guide Specification "S" documents are written in standard specification language. It is the intent of the Collaboration that these documents be adopted in whole as part of the contract documents to facilate the achievement of standardization. It is understood that local statues or preferences may preclude full adoption. In those instances it is the opinion of the Collaboration that as much of the document be referenced as possible.
A complete list of Guide Specification documents can be viewed here.
Guideline "G" Documents
Guideline "G" documents are written as references to be used during the design, fabrication, and construction processes. The documents are a concensus of best practices developed by industry. Referencing the document allows for a common language across all stakeholders, including engineers, owners, fabricators, and erectors.
