During construction of the Ridges Basin Dam in 2005, AAI 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, AAI installed 27 fiber-optic piezometer transducers and 21 vibrating-wire piezometer transducers plus 3 vibrating-wire weir gauge level transducers. An inclinometer casing and four 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 AAI installed a data acquisition system. Work was completed in 2007.
