Project Delivery Methods and Contracting Approaches Available for Implementation by the Texas Department of Transportation.

摘要

Reducing the time from planning to construction of a project can ensure that the benefits of the project are available sooner to the traveling public. Various public agencies are pursuing innovative project delivery methods such as design-build and construction manager-at-risk to improve cycle-time performance on projects, and twenty-four state departments of transportation are currently using the design-build method for highway construction. Although the Texas Department of Transportation and the Texas legislature have shown a particular interest in the design-build project delivery method, currently it is legally unavailable and is one of several delivery methods that could be beneficial. This report provides an overview of the project delivery methods, assesses the benefits of their use and compliance with current laws. This study also provides a brief review of contracting approaches that are available for highway construction. Suggested guidance to implement a design-build project delivery method is provided, as are recommendations to improve the future effectiveness of implementing alternative project delivery methods.
