NCHRP 25-25/Task 25 [Completed]

Modification and Amendment of Environmental Permits on Design-Build Projects
[ NCHRP 25-25 (Research for the AASHTO Standing Committee on the Environment) ]

  Project Data
Funds: $60,000
Research Agency: Cambridge Systematics, Inc.
Principal Investigator: Ken Hess, Louis Berger
Effective Date: 8/3/2006
Completion Date: 7/1/2007

Although a limited number of Design-Build (D/B) projects have been undertaken nationwide, it appears that there is significant interest in this technique to facilitate more expeditious project delivery and to better manage cost with respect to the DOT's overall capital budget. D/B has been implemented for complex, high cost projects which, in most cases, have involved significant environmental impacts. This task will develop guidance on appropriate methods for insuring environmental commitments are carried forward once the primary responsibility for the project is transferred from the DOT to the D/B entity.
