Dan Brown and Associates, LLC

We have added a link in our Links section to Geoengineer.org, a website resource for geotechnical engineers. Resources include an on-line technical library and an on-line photo gallery/library. They have several new information servces, including the Geoengineer.org Press Center that has the latest news of articles and press releases of interest to geotechnical engineers, and The International Journal of Geotechnical Case Histories- a new, free on-line journal. Check it out!

We are beginning to add publications by our staff to the site. A link to the Publications Page of our site is at the top of our home page. We will be adding more papers in the coming weeks. Our goal is to make this site one of your resources for deep foundation and slope stability literature.

The week of August 28th saw five load tests performed at the project site. A lateral Statnamic test and an axial Statnamic test were performed on both 24-inch and 30-inch piles. The tests were performed by AFT. A picture of one of the axial test setup is below. A static axial load tests was also performed on a 24-inch pile. Eustis Engineering, the project geotechnical engineering firm, supervised the static test. The results of the tests, along with the PDA data gathered by Eustis during driving of the indicator piles, will be used to set the pile tip elevations along the bridge alignment. Driving of production piles is set to begin the week of September 11th.
