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)
On September 30, 1935, President Franklin D. Roosevelt dedicated the Hoover Dam, telling the 10,000 people gathered at the ceremony that it was a “great feat of mankind” destined to reshape “the geography of a whole region.” The American Society of Civil Engineers calls it one of the “Seven Modern Civil Engineering Wonders.” In honor of this significant milestone for this fantastic structure, I’ve collected some facts and figures, news articles, information on the bypass bridge, and some concerning news about the future of the dam’s ability to supply power.

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.
