Geotechnical Engineering Challenges of British Columbia’s Sea-to-Sky Highway, gateway to the 2010 Vancouver Olympic Games
I don’t know about you, but I’ve been enjoying watching the 2010 Olympic Winter games over the past few days. If you have, you know that Whistler is the venue for many of the sports including alpine skiing, luge, skeleton, bobsled, ski jumping, biathlon and cross-country skiing among others. The Whistler area is located about 50-miles or so North of Vancouver. In order to get to Whistler, you need to drive along Highway 99, better known as the Sea-to-Sky Highway. This highway has a long history of geotechnical problems, including some significant structurally controlled rockslides and landslides. In the years leading up to these Olympic Games a fair amount of work was done on the highway with some significant geotechnical innovations.

Foundations and Geotechnical Engineering for the Burj Dubai – World’s Tallest Building
The Burj Dubai Tower has recently reached it’s final height of 818m (2,684-ft or almost exactly 1/2 a mile!). The foundation system for the Burj Dubai is comprised of 192 bored piles (drilled shafts in my practice) 1.5-m (approximately 5-ft) in diameter and approximately 50-m deep (164-ft). A 3.7-m (12-ft) thick raft foundation sits on top of the piles under the full footprint of the structure. (Image from BurjDubaiSkyscraper.com)
The geotechnical investigation for the Burj Dubai (now to be known as Burj Khalifa after the UAE President) is described in detail in a paper by the geotechnical engineer of record, Grahame Bunce of Hyder Consulting (UK) and the independent technical reviewer for the geotechnical design, Harry G. Poulos of Coffey Geotechnics. Click through for the link to the paper and more details. […]
