Title
Additional Funding for Project 20-07/Task 245, FY 2010
Update AASHTO Design and Construction Specifications and Guidelines Related to the
Temporary Works Used in Bridge Construction
Background
In 1991, a study was initiated by the Federal Highway Administration (FHWA) to identify
the current state of practice in the United States and abroad for designing, constructing, and
inspecting the temporary works used to construct highway bridge structures. This study was
known as the FHWA Bridge Temporary Works Research Program. Two of the documents
produced from this study were FHWA Publication No. FHWA-RD-93-032, Guide Design
Specification for Bridge Temporary Works and FHWA Publication No. FHWA-RD-93-034,
Construction Handbook for Bridge Temporary Works. Both of these documents were adopted
by the American Association of State Highway and Transportation Officials (AASHTO) in
1995. There have been several initiatives since publication of the AASHTO Guide Design
Specifications for Bridge Temporary Works and the AASHTO Construction Handbook for
Bridge Temporary Works that have advanced the design and construction of the temporary
works used in bridge construction. Most notably, AASHTO produced provisions for
temporary works in the 1991 Interim Specifications and subsequently incorporated these
provisions in the AASHTO LRFD Bridge Construction Specifications. Based upon the period
of time that has lapsed since the development of the original Guide Design Specification and
Construction Handbook, and the development of other related standards within this period of
time, the reassessment and updating of these publications is necessary.
Objective
The objective of this project is to update the AASHTO Guide Design Specifications for
Bridge Temporary Works, the AASHTO LRFD Bridge Construction Specifications, and the
Bridge Construction Handbook for Bridge Temporary Works.
Tasks
Task 1. Prepare outlines for revisions to the AASHTO Guide Design Specifications for
Bridge Temporary Works, the AASHTO LRFD Bridge Construction Specifications, and the
AASHTO Construction Handbook for Bridge Temporary Works. Submit to Task Group for
review and comment.
Task 2. Meet with Task Group to review comments. Revise outlines accordingly.
Redistribute outline to the Task Group.
Task 3. Revise documents in accordance with outlines. Submit to Task Group for review,
comment, and approval.
Task 4. Perform final revisions to documents. Prepare final report that documents research
effort and includes updated Guide Design Specifications for Bridge Temporary Works,
AASHTO LRFD Bridge Construction Specifications, and Construction Handbook for Bridge
Temporary Works.
