      To help DOTs with their specialized technical impasses, a unique team of experts has been assembled through the S-BRITE Center to create a Distributed Expertise Network (DEN). Some of these individuals are housed locally at the Center while others are located at their respective institution. The DEN serves the role that no longer exists in many individual state DOTs today, specifically the existence of a group of highly specialized technical experts that are “on-call” to assist as issues arise. Providing access to such individuals makes the S-BRITE Center the national "go-to" place for solutions to complex issues regarding steel bridges, from high-profile failure investigations to working with policy makers on setting the future paths for asset management of the existing steel bridge inventory. No other such entity  or resource exists in the United States.  In addition, a database is made available to partnering states archiving the questions posed to the DEN.  Thus, states with similar issues are quickly able to find answers to their tough questions.

 

Do you have a question for the DEN?  Please email or telephone Dr. Robert Connor, rconnor@purdue.edu or 765-496-8272, with the details.
