Specialty geotechnical drilling contractor Holocene Drilling of Edgewood, WA recently completed work on an interesting project for Sound Transit’s U-220 TBM Tunnel Project at the University of Washington Campus in Seattle. Their scope included drilling and installing inclinometers and borehole extensometers to monitor possible ground movements related to the tunneling operation. They were also retained by Hayward Baker to perform borings after jet grouting to verify the size and condition of the jet grout block. [Source: National Driller. Image: Holocene Drilling]

Newport Bridge, Newport, R.I., much of the BART subway system and Boston’s Big Dig were among the numerous significant projects worked on by the late Thomas R. Kuesel. He was a well known civil engineer and tunneling expert, co-editor of the “Tunnel Engineering Handbook,” a standard reference for design and construction used worldwide. One of his most noteworthy tunneling projects was the NORAD Combat Operations Center beneath Cheyenne Mountain near Colorado Springs, built during the height of the Cold War and designed to withstand a nuclear blast.
