Development of Warranty Based Specifications for Construction

The Texas Department of Transportation (TxDOT) has continued to be proactive in fmding innovative practices in programming and administering projects, including the construction contracting area. Warranty specifications show potential for reducing the life-cycle cost of facilities while ensuring the quality of constructed facilities. This report documents the research effort and fmdings for TxDOT Project 0-4498, "Warranty Based Specifications for Construction." The overall approach to this research leverages off of the guidelines documented in National Cooperative Highway Research Program (NCHRP) Report 451. The researchers modified these guidelines for consistency with TxDOT design, contracting, and maintenance systems.
