Abstract
This study examines the usage of design-build by the Department of Transportation (DOT) of the 50 states in the United States. Design-build has been growing in popularity as a procurement form in both the private and public sectors, and in the last ten years many DOTs have started or expanded programs to use design-build for infrastructure projects. However, many DOTs are still struggling to determine the best application of design build and how to incorporate its use as a procurement method for DOT projects. This study examines how state DOTs are using design-build, when they are using this delivery method, and the processes that the DOTs have established when utilizing design-build. This was accomplished by examining design-build documents that have been published online for each of the 50 state DOTs. It was found that while the large majority of state DOTs are using design-build, only around half of the DOTs have a design-build manual, and only two DOTs have published comparative analyses of design-build projects. The most commonly cited reason for using design-build was its shorter delivery schedule. Also, this study found that most state DOTs complete preliminary design work in house for design-build projects before going through a two-phase selection process to award a contract.
