GEO-Instruments Application Notes

A deep excavation at Dulles International Airport was needed in order to build a new terminal related infrastructure, and to facilitate tunneling operations connecting to the main terminal. In order to allow safe construction to continue inside the excavation, Airport management required that the support of the excavation system, be monitored for movements with In Place Inclinometers.
Geo-Instruments supplied over 450 vertical IPI sensors, installed in over 40 inclinometer casings, connected to 6 remote dataloggers. Data is collected for the loggers hourly by a Geo-Instruments server, processed and displayed on a project web site for the concerned parties to view. Real time e-mail alarms can also be accommodated in this system.
