Abstract: Transportation projects have traditionally been delivered through the design-bid-build (DBB) delivery model, which continues to be the preferred method of delivering the majority of smaller and more traditional projects. Recently, however, elected officials and agency professionals have been seeking ways to accelerate delivery of infrastructure improvements in response to demands by the public to find a better way. This response has caused many transportation agencies to turn to alternative delivery methods such as public-private partnerships (P3), design-build (DB), and construction manager/general contractor (CM/GC). There are myriad reasons for agencies to ask for accelerated delivery, including environmental factors, impacts on traffic and the local economy, material and labor cost escalations over time, lost economic opportunities, and global competitiveness, just to name a few. So, what challenges do geo-professionals face when it comes to accelerated delivery of mega transportation projects?
