This report documents the results of the SHRP 2 R07 project to develop and implement performance specifications for rapid highway renewal. The project adopted a broad definition of performance specifications to address not only the performance of the physical products of construction (including pavements, bridges, and earthwork) but also contractor performance in terms of time, safety, work zone traffic control, and other important project parameters. Performance specifications were considered in the context of different project delivery methods, including design-bid-build and design-build delivery and other innovative contracting variations involving warranties or maintenance and operation agreements. The products of the research include guide performance specifications for different application areas and delivery methods that users may tailor to address project-specific goals and conditions. Implementation guidelines were also prepared to accompany the guide specifications. To validate these materials, demonstration projects were conducted for geotechnical and bridge deck applications. The findings of the study generally support the use of performance specifications as a viable option for agencies interested in empowering the private sector to provide creative solutions to save time, minimize disruption, and enhance durability in the interest of rapid renewal. TRB’s second Strategic Highway Research Program (SHRP 2) Renewal Project R07 has released a prepublication, non-edited version of a report titled Performance Specifications for Rapid Highway Renewal that describes suggested performance specifications for different application areas and delivery methods that users may tailor to address rapid highway renewal project-specific goals and conditions. SHRP 2 Renewal Project RO7 also produced Implementation Guidelines: Volume I: Strategies for Implementing Performance Specifications: A Guide for Executives and Project Managers (http://www.trb.org/Main/Blurbs/169108.aspx) that is designed to provide a broad overview of the benefits and challenges associated with implementing performance specifications; and Implementation Guidelines: Volume II: Developing and Drafting Effective Performance Specifications: A Guide for Specification Writers (http://www.trb.org/Main/Blurbs/169109.aspx) that presents a flexible framework that specifiers may use to assess whether performance specifying represents a viable option for a particular project or project element, and if so, how performance specifications may then be developed and used to achieve project-specific goals and satisfy user needs.
