Montgomery Locks & Dam

Montgomery Locks and Dam is a lock and dam on the Ohio River 32 miles downstream of Pittsburgh. Montgomery Locks and Dam were constructed between 1932 and 1936. Dams were built by the US Army Corps of Engineers to create the first shallow navigational pool on this stretch of the Ohio.

Montgomery Locks & Dams, built in the 1936 was exhibiting significant deterioration. For repair and restoration works, a secant pile wall needed to be constructed at Montgomery Locks and Dam. In order to monitor the stability of the existing dam Apron and Pier 1 during secant pile construction activities, sensors were required to be installed on the concrete apron surface and at the top of Pier.

Rite Geosystems Inc, USA, was awarded the contract for the instrumentation and real time monitoring works. Instruments used included piezometers, crack meters, tilt meter, vibration sensor and automatic data loggers. 
Rite Geosystems’ expert team provided installation and commissioning services. Online data was available to all stake holders via web based data management software.
