Dataforensics pLog Tablet Software running on ruggedized Panasonic Toughpad A1Norcross, GA - September, 2013 – Dataforensics is the focus of an article distributed by technology industry leader Panasonic Systems Communication Company. The article is the result of a case study performed by Panasonic re-seller, DataSource Mobility.

Dataforensics has invested more than a decade creating software that is flexible, customizable and improves the field data collection process. Software is only one piece of the puzzle, hardware that is capable of withstanding field conditions, but also captures photo/video data, GPS data all while having the battery life necessary for a full day’s work is the other.

With the release of the Toughpad line of rugged tablets, Panasonic has delivered a unit that fulfills exactly the needs of pLog users.

“We’ve been waiting for this device for 13 years. We are now able to offer our customers a complete solution to capture data from the field in real-time. The Toughpad FZ-A1 has allowed us to do more than we could ever do before” states Scott Deaton, President.

Video: Tests holes reveal buckled pile, corrosion at Leo Frigo bridge PDF Print E-mail

A portion of the geotechnical investigation at the Leo Frigo bridge on October 3, 2013

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 to determine that the steel H-Piles at Pier 22 buckled which is what produced the nearly 2 feet of settlement of the pier and the resulting deformation of the bridge deck. Investigations at adjacent piers also confirmed that there is a corrosion issue with other piles. They are still working on a solution to the problem. [Source: greenbaypressgazette.com. Image: H.

Happy Karl Terzaghi’s Birthday 2013! PDF Print E-mail
Written by Randy Post

terzaghi_birthdayEvery second of October, geotechnical engineers around the world remember Karl Terzaghi on his birthday! Terzaghi is the father of soil mechanics, and I don't think it is cliche to say he is also the father of our profession. So happy KTB 2013! It's a big one for Karl, he would have been 130 today by my calculation!

I always like to celebrate by reading some of his quotes, many of which seem like they could have been written to us today…like this one:

…as soon as we pass from steel and concrete to earth, the omnipotence of theory ceases to exist. In the first place, the earth in its natural state is never uniform. Second, its properties are too complicated for rigorous theoretical treatment. Finally, even an approximate mathematical solution of some of the most common problems is extremely difficult.

Leo Frigo Bridge in Green Bay, Wisconsin Pier Settles PDF Print E-mail

Settlement of Pier on Leo Frigo Bridge - Photo by H. Marc Larson/Gannett Wisconsin MediaPier 22 of the Leo Frigo Bridge settled 22 to 27 inches last week causing a 400 foot long segment of the bridge to sag dramatically, forcing the closure of the bridge. There were no reports of injuries and there has been no further reports of additional movement of the pier.

The pier is approximately 700 feet from the edge of the Fox River. The pier is a hammerhead-type pier with two columns extending down to the ground. The foundation system consists of footings supported by a group of steel piles 100 feet long. Highway spokesmen would not speculate on the cause of the settlement.

If you look at the photos of the bridge, there does not appear to be any structural damage to the pier, it looks like the entire pier just settled. So this geotechnical engineer’s opinion is that it certainly seems likely this is a geotechnicl type of failure. But we will have to wait until additional information is released.

The Bayou Corne Sinkhole was formed near Baton Rouge Louisiana last September, likely as a result of the failure of salt caverns below. This video shows a stand of trees being swallowed by the sinkhole in pretty dramatic fashion.

TRB Guide for Conducting Forensic Investigations of Highway Pavements

TRB's National Cooperative Highway Research Program Report 747: Guide for Conducting Forensic Investigations of Highway Pavements explores a process for conducting forensic investigations of pavements that is designed to help understand the reasons behind premature failures or exceptionally good performance. The process also allows for the collection of data for use in developing or calibrating performance-prediction models.

The report includes example forms and checklists for use during the conduct of an investigation. These forms can be modified to suit the particular requirements and procedures for the agency. The example forms are included with the print version of the report in CD-ROM format. [Source: Download the Report and/or CD ISO from TRB. Image: TRB]

Basement Excavation for Seattle High-Rise PDF Print E-mail

dbm_excavationLast week I attended the AEG 2013 conference in Seattle, Washington. The conference was excellent, with many great presentations and networking opportunities. I have been playing catch-up since I returned, but I have some very interesting things to blog about once I sit down and start writing. Keep watching!

One interesting thing was the view right outside my hotel window. I could see the construction site for a new high-rise building which is currently being excavated by DBM Contractors, a specialty geotechnical contractor based in Federal Way, Washington (Seattle Metro area). I didn’t see mention of this project on DBM’s website, but they did work on a similar project just a few blocks away. It looks like there are soldier pile lagging retaining walls with multiple levels of anchors. I imagine that once they finish the excavation, they will also construct the drilled shaft foundations for the structure as well. I'm guessing they performed some de-watering as well.

Maybe I got a little over-excited, but I don’t see these types of excavations too often in my geotechnical practice!
