China Town DC

GEO deployed an AMTS to monitor the stability of the buildings adjacent to this deep excavation in Washington DC’s historic Chinatown.

Chinatown DC Prisms

Optical prisms were installed on the buildings and also on elements of the SOE. A change in the spatial coordinates of the prisms would indicate that movement had occurred.

Chinatown DC Solar power

Every two hours, the solar-powered system transmitted measurements to GEO’s web-based monitoring platform, where they were processed, checked against alarm limits, and posted on a website.
