The Geotechnical Extreme Events Reconnaissance (GEER) Association published their report last month on the January 7, 2020, Puerto Rico Earthquake. Here is the summary: A seismic sequence located along the southwestern coast of Puerto Rico […]
A debris-laden landslide has closed SR 706, the popular road from Ashford, Washington to Mt. Ranier National Park. The road was first closed on February 6 as portions of the highway were covered with debris […]
[Editor] The Delaware Department of Transportation (DelDOT) had a major problem on their hands after a bridge on I-495 was leaning…one side of the bridge was 18 inches higher than the other. The culprit? A pile of fill adjacent to the bridge was loading soft soils beneath. So what do you do about it? In this contributed article by Dennis M. O’Shea, bridge engineer in the FHWA Delaware Division Office, he describes the problems faced by DelDOT, the causes, and how they fixed it. The article originally appeared in Public Roads Magazine, and is republished here with permission. [/Editor]
Turning a 119 year old brewhouse into a four-star boutique hotel is no easy task. For the project to be a success, the structure had to literally be raised from it’s grave.
Pearl Brewery operated from 1883 until 2001 in their downtown San Antonio, Texas location. It was once the largest brewery in Texas, and even kept afloat during the Prohibition era. Today the 22- acre Pearl site grounds has become a culinary gathering place where you can eat, live, learn, and play on the banks of the San Antonio River.
Renovating the original building would be no easy task for the developer. The building had settled approximately 5 inches. URETEK ICR successfully used their patented URETEK Method® to lift and stabilize the foundation with geopolymer.

The City of North Haven is located on an island off the coast of Maine. This town was faced with a unique challenge when a bridge needed replacing. Looking for an economical option, designers decided on a Geosynthetic Reinforced Soil – Integrated Bridge System (GRS-IBS). This solution allowed the town and DOT to re-use an existing bridge pier, beat the construction deadlines, and provide a modern bridge solution for this small town.

[Editor] An effluent pond in southeast Texas was suffering from years of erosion. Recently, an escalation of subsurface water seepage through the pond’s embankment threatened the community’s main water source. URETEK used their versatile geopolymer product to inject beneath the embankment to seal off the seepage. The project was a huge success!

Most people reading this will have driven along a highway recently. But did you ever stop to think about how it stays up? With all the trucks and cars that speed along the average highway every day, it’s a wonder they don’t collapse!
Now how would you feel if you heard that the reason these highways and bridges and embankments manage to stay so stable is all thanks to the simple triangle?

Getting the Message Across
Applying Building Information Modelling principles to geotechnical data will reinforce the message that geotechnics is an integral part of every phase of a project – not just site investigation, argues Gary Morin, Technical Director, Keynetix.
[Editor] In this contributed article, Gary describes the justification for using BIM for geotechnical data. Among those benefits are the ability to perform detailed alternatives analysis and optioneering, reduction of risk during construction, and the ability to perform cost-effective repairs and maintenance during the lifetime of the geotechnical asset.

I first heard about Geotech Tools through a TRB Strategic Highway Research Program (SHRP 2) publication titled Geotechnical Solutions for Soil Improvement, Rapid Embankment Construction, and Stabilization of the Pavement Working Platform. The final version of the report was released in February of this year. The report is one of the project deliverables for the SHRP 2 Project R02.
The primary deliverable of the project and the subject of this review is Geotechtools.org, a web-based tool for geotechnical engineers, structural engineers and pavement engineers. This website is a “toolkit of geotechnical information to address all phases of decision making from planning to design to construction.” What does that mean exactly? Great question. In this article I will give you an overview of the site and its resources and how it might help you on your next project.
