Bob Brown with Arizona Foundation Repair, a foundation repair contractor, has a nice blog post about the need for better standards for forensic investigations for residential foundation investigations. He points to some standards by a […]
The Wisconsin DOT has been performing geotechnical drilling and test pitting to try and determine the cause of the foundation failure at Pier 22 of the Leo Frigo Bridge in Green Bay. They were able […]
The Burj Khalifa is founded on pile supported raft foundation consisting of 194 bored-in-situ piles or drilled shafts as we commonly call them in the US with a 12 foot thick mat. The piles were […]
Super Storm Sandy was the most recent reminder of the dangers posed to building foundations by storm surge, waves, scour and erosion. The January 2013 issue of Civil Engineering Magazine by the ASCE has a […]
Hawthorne, NJ (December 1, 2012): Co-authors Dr. John McCartney and Kyle Murphy, professors at the University of Colorado Boulder, shared honors as winners of the DFI Young Professor Paper Competition award presented at the DFI 37th Annual Conference on Deep Foundations in October in Houston. The paper, “Seasonal Strain Distributions in Full-Scale Energy Foundations,” focuses on the seasonal thermo-mechanical response of two energy foundations installed at the new Denver Housing Authority Senior Living Facility.

The Kingdom Tower to be built in Jeddah, Saudi Arabia will be 1,001 meters tall when completed in 2018. It will be the first building taller than 1-km and 173 meters taller than the Burj […]
Sports fans are eagerly awaiting the matchup between the Pittsburgh Steeler’s and the Green Bay Packers in Super Bowl XLV (That’s 45 for the roman numeral challenged). The venue for the Super Bowl is the new Dallas Cowboy’s Stadium in Arlington and it is certainly a show piece and engineering marvel worthy of this world class sporting event. And it required some very interesting geotechnical engineering design as well… (Photo: NFLTouchdown.com)
In the foundation and basement excavation for the Vehicle Security Center at the World Trade Center cite, an 18th century cargo ship was discovered approximately 20- to 30-ft below street level. It was likely a […]
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. […]
This has to be one of the most complex geotechnical engineering problems I’ve heard of for a building, if not for any kind of project. For starters, beneath the proposed 10-story office building referred to as Cannon Place lies the Cannon Street Train Station built in 1868. Also beneath the site are walls and foundations of a Roman Governor’s palace. In order to accommodate these features, the building has 21-m cantilevers at each end, with the load bearing happening over two groupings of columns at the 1/3 points. In section it looks quite like a 3-span bridge…without the abutments and stacked 10-stories tall! More after the break. (Images by New Civil Engineer) […]
