Sean McDonald,

Sean McDonald is a Senior Field Engineer employed by Jay Dee Contractors, Inc. in underground construction and tunneling. He earned a Bachelors of Science in Mining Engineering from Colorado School of Mines with an interest in explosives. He has worked on a number of tunneling projects for Jay Dee, including their projects in Charleston, South Carolina and Detroit, Michigan. He has been involved in a variety of shaft and tunnel excavation methods; including caissons, rib and lag shafts and tunnels, hand mined tunnels, road header tunnels, and segmental lined tunnels. Sean’s current focus is in optimizing the methodologies and logistics of tunneling, both in underground and surface portions of projects. Outside of work, you can catch Sean at the golf course or out fishing.

Rajat Gangrade,

Rajat is a Ph.D. candidate in Underground Construction and Tunneling at the Colorado School of Mines. His doctoral research focusses on quantifying, understanding, and communicating spatial uncertainty and risk for soft-ground tunneling applications. The objective of my research is to develop a smart risk assessment and decision-making tool capable of optimizing site-investigation & instrumentation-monitoring strategies, improve knowledge of the tunnel excavation environment, visualize models of relevant tunneling risks and quantify the implications of spatial variability and uncertainty in subsurface conditions. Prior to joining Ph.D. at Mines, he has worked as a geotechnical engineer with Jacobs on multiple DOT projects and with AECOM on Mumbai Metro Line 3. Rajat holds an M.S. degree in Geotechnical Engineering from Virginia Tech. in 2013 and a Bachelors's degree in Civil Engineering from VJTI, Mumbai.
