The drilled shaft foundations for the kcICON bridge over the Missouri River have been completed according to Dan Brown and Associates, LLC, the geotechnical engineers on the job. The 1700-ft long bridge conveys the I-29/35 over the River with the central spans being cable-stayed and supported by a single pylon in the river. The foundations for the central pylon consist of 8 10.5-ft diameter shafts socketed into bedrock. The land-based bents are supported on 6.5 to 8-ft diameter shafts and the abutments are on driven piles. Some of the drilled shafts were post-grouted as well. The project is scheduled for completion in the summer of 2011. Find much more about the project at the DBA website. (Photo by Dan Brown and Associates)

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. […]
