AASHTO/NSBA TASK GROUPS
The following task groups fall under the AASHTO/NSBA Steel Bridge Collaboration Main Committee. The mission of the Collaboration is to achieve quality and value in steel bridges by standardization of design, fabrication, and erection, and by the sharing of resources. Through the Collaboration, steel bridge professionals work together in a spirit of cooperation and mutual respect to develop details, specifications, and practices, and to exchange knowledge, technology, and expertise.
Task Group 1 (TG 1) - Detailing
This Task Group is specifically responsible for the creation and maintenance of guidelines and best practices for the creation of clear concise design and fabrication drawings.
Task Group 2 (TG 2) - Fabrication and Repair
This Task Group aims to achieve quality and value in the fabrication of steel bridges through standardization of steel bridge fabrication across the nation. Historically, State Departments of Transportation (DOTs) have written their specifications based on AASHTO standards and their own individual experiences.
Task Group 4 (TG 4) - QC/QA
This Task Group focuses on the requirements for a fabricator’s quality control program, with emphasis on the development and implementation of a quality control plan and minimum requirements for an owner’s quality assurance program.
Task Group 8 (TG 8) - Coatings
This Task Group primarily focuses on the functions, operations, requirements and activities needed to achieve consistent quality in steel bridge coatings. At the same time the group acknowledges the need for a cooperative approach to quality, where the Owner’s and Contractor’s representatives work together to meet their responsibilities, resulting in efficient steel bridges coatings that meeting all contractual requirements.
Task Group 9 (TG 9) - Bearings
This Task Group is specifically responsible for the creation and maintenance of guidelines and best practices for steel bridge bearings.
Task Group 10 (TG 10) - Erection
This Task Group develops guidelines that establish and define the basic, minimum requirements for the transportation, handling and erection of steel bridge components to ensure safe and accurate steel erection as well as quality and value in the completed bridge structure.
Task Group 11 (TG 11) - Design
This Task Group is primarily responsible for the development and maintenance of consensus guidelines to assist with the design of steel bridges and their components.
Task Group 12 (TG 12) - Design for Constructability and Fabrication
This Task Group focuses on addressing the questions that have been and are continually asked concerning the constructability of steel bridges according to the latest practice for steel mills, fabrication, detailing, erection, and design.
Task Group 13 (TG 13) - Analysis of Steel Bridges
This Task Group focuses on the development of guidance on the issues related to steel girder bridge analysis and to educate Engineers so that they can better make decisions for their own projects.
Task Group 14 (TG 14) - Field Repairs and Retrofits
This Task Group primarily focuses on providing practical solutions for design and implementation of field repairs and retrofits of existing steel bridges.
Task Group 15 (TG 15) - Data Modeling for Interoperability
This Task Group focuses on facilitating the development of bridge industry consensus standards for data description, modeling, and interoperability for integrated design, construction, and lifecycle management of bridges (i.e., BIM).
Task Group (TG 16) - Orthotropic Deck Panels
This Task Group aims to establish an Orthotropic Steel Deck (OSD) panel design that can be cost effectively produced in the United States for the bridge market.
Task Group (TG 17) - Steel Castings
The mission of this Task Group is to develop and disseminate resources specific to the US steel bridge community to support the increased and effective use of castings in steel bridges. The targeted community includes design engineers, DOT professionals, steel fabricators, steel erectors, inspectors, general contractors, especially on design/build projects, and detailers.
Task Group (TG 18) - Duplex Stainless Steel
This Task Group will include experts from the carbon steel and stainless steel communities and will work together to develop standalone material, design, welding, fabrication, and construction guide specifications for using duplex stainless steel for vehicular plate girder bridges. These guide specifications will be largely based on existing duplex stainless steel design and fabrication specifications (such as AISC 370), but will be revised to provide the same formatting and flow as the standards typically used in the steel bridge community, such as AASHTO LRFD or AASHTO/AWS D1.5.
AASHTO/NSBA STEEL BRIDGE COLLABORATION MAIN COMMITTEE
The Collaboration Main Committee provides oversight and guidance for all of the AASTHO/NSBA Steel Bridge Collaboration Task Groups.
