During construction of the Ridges Basin Dam in 2005, DA Smith* was commissioned by the Weeminuche Construction Authority to drill boreholes and install piezometers and one inclinometer into the dam foundation.
Over the next 2 years, DA Smith installed 27 fiber-optic piezometer transducers and 21 vibrating-wire piezometer transducers plus 3 vibrating-wire weir gage level transducers. An inclinometer casing and 4 survey instrument piers were also installed at the dam.
Over 48,000 feet of fiber-optic and vibrating-wire cable was installed in trenches and pulled through the conduit into a control house where DA Smith installed a data acquisition system. Work was completed in 2007.
