Lower Granite Dam | Pomeroy, WA

Lower Granite Dam

This project included installation of thirty-two 54" diameter drilled shafts with 48" diameter rock sockets using sectional casing and oscillators, half of which were installed over water from work trestles. Each of the shafts required permanent casing that penetrated into R4-R5 basalt bedrock. The casing was installed by first driving it into bedrock, then using a casing oscillator to cut through the rock to provide a seal. We also installed 62” diameter shafts to depths of 75 feet from a barge deck using our Bauer BG40 drill rig.  The project also included 12 permanent micropile anchors embedded into rock to anchor a 15-foot diameter mooring dolphin.
