7C h a p t e r 1 Background Transportation agencies are under increasing pressure to improve mobility while maintaining existing facilities with limited resources. In response to this pressure, agencies have begun experimenting with ways to accelerate construction and minimize disruption to existing users while improving mobility, safety, and long-term performance.

8Understanding the basic rationale for using performance specifications is therefore an important first step toward ensuring successful implementation. Once identified, these objectives must be prioritized and then communicated, understood, and accepted by all parties involved.

9research products As an outgrowth of its research efforts, the R07 team developed guide specifications and associated implementation guidelines to support the application of performance specifications across a wide range of work and projects. Guide Specifications To help agencies with the specification development process, the team prepared a set of guide performance specifications that specifiers may use as a template from which to develop projectspecific performance requirements.

10 specifications to develop and tailor performance specifications to help achieve project goals. research Scope and Objectives The specifications and implementation guidelines were designed to meet the following stated objectives of the R07 project: • Reduce the completion time of renewal projects while maintaining or improving quality; • Encourage further innovation by reducing mandatory method requirements and defining end-product performance; • Develop different performance specifications for highway construction (pavements, bridges, work zone, etc.)
