Pittsburgh, PA – June 2, 2011 – Missouri’s Interstate 44 is considered one of the most frequently traveled highways in the central United States. In early March of 2011, Nicholson Construction was contacted to perform an emergency response grouting operation on the Gasconade Bridge, part of I-44 westbound, over the Gasconade River in Laclede County.

Instrumentation systems for geotechnical and structural monitoring often entail monitoring large numbers of sensors of different types with dataloggers often being installed in remote, inaccessible and hostile locations.
