Foundations and Geotechnical Engineering for the Burj Dubai – World’s Tallest Building

January 5, 2010 rockman 15

Foundations for the Burj Dubai - The raft slab on top of 192 pile foundations 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. […]

Most Popular GeoPrac.net Content of 2009

December 31, 2009 rockman Comments Off on Most Popular GeoPrac.net Content of 2009

Best wishes for a happy and prosperous 2010 to all the readers of GeoPrac.net! I am grateful for all of my readers, visitors and sponsors for a great 2009 and I look forward to continuing to work in the new year towards making this site one of the best online resources for geotechnical engineers, geoengineers and all professionals in the geo-industry.

As is customary for bloggers at this time of year, I have listed below the top 100 GeoPrac.net stories published in 2009. Long-time readers of GeoPrac know that I don’t like to rank the articles by total number of ‘hits’, since I think that biases the rankings towards the ones that have been published longer. Instead, I order them by hits per day. I think that works well when looking at popularity of content on a monthly basis, but just for grins I’ve also included the top 100 items of all time (based on total page impressions). Again, Happy New Year!
