44 C h a p t e r 4 A review of the information gathered during the R07 research effort -- including findings from the literature review, practitioner input, and analysis of case studies and demonstration projects -- shows that performance specifications can increase quality, encourage innovation, promote the use of new materials and technology, and reduce an agency's quality assurance burden during construction. To achieve these benefits, performance specifications should emphasize desired outcomes (either through as-constructed end-result requirements or target levels of service over some defined period of performance)

45 of the benefits and challenges associated with implementing performance specifications. Recommendations address project selection criteria, procurement and project delivery options, industry and legal considerations, and the various cultural and organizational changes needed to support the implementation of performance specifications.

47 Performance specifications could be further validated by conducting long-term, postconstruction performance monitoring to assess their relative value. Particularly useful would be demonstrations of the long-term performance outcomes for warranty and DBOM specifications using postconstruction performance parameters.

48 consistent with current agency trends toward developing and maintaining web-based specifications. The tool would generally be based on the guide for specification writers and could be database-driven with standard language and templates for different types of product specifications.
