Research for AASHTO Standing Committee on Highways. Task 245. Updating AASHTO Design and Construction Specifications for Temporary Works used in Bridge Construction

Bridge owners across the United States are faced with critical, and often conflicting, problems: constructing bridges more quickly than ever before, and erecting these same bridges safely over or adjacent to traffic. Furthermore, highway agencies are also asked to make use of innovative project delivery methods, consider value engineering ideas during design and construction, and be open to a contractor's means and methods. The replacement and widening of these structures is a safety concern if an erection plan is not developed and then followed through in the field. Guidance on bridge construction practices for temporary works is available in a number of AASHTO publications, such as Construction Handbook for Bridge Temporary Works (1995); the Guide Design Specifications for Bridge Temporary Works (1995), and the AASHTO LRFD Bridge Construction Specifications, 2nd edition, 2007 Chapter 3 - Temporary Works. The research that led to the AASHTO Construction Handbook and Guide Design Specification was conducted under FHWA Contract No. DTFH61-91-C-00088 by Wiss, Janney, Elstner Associates, Inc., Northbrook, Illinois. These were published by FHWA as FHWA-RD-93-034 and FHWA-RD-93-031. AASHTO re-published the documents as CHBTW-1 and GSBTW-1 in 1995. There is a need for these documents to be updated to reflect present practices including the LRFD design methodology. Because of the extent of the revisions it is envisioned this work will be done in multiple phases.  The objectives of this phase of the study are 1) to update the Guide Design Specifications for Bridge Temporary Works, and 2) to develop a research plan for updating the Construction Handbook for Bridge Temporary Works, and provisions for updating the 'temporary works' section of the AASHTO LRFD Bridge Construction Specifications.
