Project:

Precision Monitoring of Mactaquac Generating Station

Location:

Keswick Ridge, New Brunswick, Canada (2010-2011)

Purpose:

Detection of mm level displacements of main intake and diversion

Configuration:

2 reference stations, 4 monitored stations

Communications:

Local WiFi and global Internet network

Details:

Swelling of concrete due to Alkaline Aggregate Reaction  and thermal effects cause the main intake and diversion structures to move  several mm over the course of a year. GNSS has been implemented to complement  existing instrumentation for monitoring structural deformation. The main challenge as this site is obstruction of satellite observations due to surrounding infrastructure. GNT’s mmVu® deformation monitoring software provides mm-level, 3D positions in real-time, 24/7.
