About the Dam
Constructed in 1931, The Big Tujunga Dam is situated 10 miles northeast of Sunland, California, and is a variable radius concrete arch which functions as a flood control and water conservation facility. The dam crest is at elevation 2304 feet, the dam is 244 feet in height and thickness varies from 8 feet at the crest to 73 feet at the base of the maximum section.

Project Parameters
The owner, Los Angeles County Department of Public Works (LACDPW) has awarded this FEMA backed Seismic rehabilitation project, during which the existing wall will be thickened on the downstream face by an additional 12 feet at the crest and 66 feet at the base.

Control requirements
A New Process Control and Seismic monitoring system will be integrated into the new design by FluidIQs. This will be used to measure reservoir water level, allow control of water movement via new cone valves & monitor weather, seepage, uplift, foundation and structural movements.

Conventional SCADA and PLCs will be installed in conjunction with specialist Seismic instrumentation (eg Piezometers accelerometers, extensometers), communications is via Fiber Ethernet with a satellite link to the owners Pasadena headquarters.

The project also features an extensive temperature recording network of over 100 probes to be used for monitoring of concrete curing during construction.
