Nicholson Construction is hosting another great webinar in their 60mn webinar series!! Their Former Chief Engineer, Tom Richards is going to present on Static Load Testing of Piles. He will cover the rules to carry out load tests, […]
A static load test was being performed on (presumably) a group of piles at a construction site on Gilstead Road in Singapore in 2011 when the massive pile of concrete blocks toppled over, blocking the […]
Samuel Paikowsky, Ph.D., Department of Civil and Environmental Engineering, University of Massachusetts Lowell, and president of GeoDynamica Inc. delivered the 2019 DFI Osterberg Memorial Lecture at SuperPile ’19 in Seattle, May 2019. The title of […]
Pile Dynamics Inc. is a global leader in deep foundation quality control and performance testing. They are known for their specialty geotechnical software and equipment, including Pile Driving Analyzer (PDA), and thermal integrity profiler (TIP). […]
Geotechnical software company, Deep Excavation, LLC has just announced a new software product for design of deep foundations. The product page for DeepFND notes that it brings together geotechnical design and structural design of deep […]
A pile static load test went awry in Singapore when a pyramid of dozens of concrete blocks used for the reaction force toppled over into Gilstead Road. The force of the collapse caused a gas main to rupture but there were no reports of injuries. Click through for the video.
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. […]
ADSC published a summary of some research being conducted by the University of Texas, Arlington (UTA) through funding by TxDOT. The research involves the lateral load testing of drilled shafts that are used for cable […]
Another nice post from Robert Thompson with Dan Brown and Associates (DBA) about the geotechnical work on the kcICON project. They are the geotechnical designers for a $245 million project that will involve a new cable-stayed bridge over the Missouri River in downtown Kansas City along the I-29/35 corridor. In his post, Robert gives an update on the status of the work including the borings and recent test shaft installation and testing as well as an update on the overall project.

Robert Thompson of Dan Brown and Associates has posted a wrapup of the 2008 ADSC Faculty Workshop. They had 20 Civil Engineering faculty attend the event. The field demonstration day was hosted by DBA at the Trial’s Training Center in Sequatchie, Tennessee. Apparently that site is Dan’s hobby. Read more about the workshop itself and also read Robert’s post about the field demonstration day including photos. In the photo at right (Robert Thompson, DBA) you can see the Statnamic test setup for a drilled shaft. A little more about the event:
Long Foundation and Hayward Baker have installed examples of several foundation and retaining structures, including drilled shafts, micropiles, and soil nails. During the field day demonstrations, the attendees will observe additional installations, load tests, and non-destructive testing.
