GeoPrac is pleased to announce our newest sponsor, Gintegro! Please check them out and the powerful geotechnical software they distribute, GEO5. Be sure to let them know how you heard about them! Gintegro is a […]
Laboratory accreditation has become a ‘ticket to the game’ and most geotechnical laboratories will have, or are working towards, accreditation. The key thing an accreditation body is looking for is consistency; in workflows, sample handling, […]
A massive landslide covered California’s famous Pacific Coast Highway (PCH) in 35 to 45 feet of soil and rock over a distance of 1,500 feet. Caltrans is calling the landslide ‘one of a kind’ and […]
Specialty geotechnical contractor Moretrench is pleased to welcome Martin McDermott, P.G., who joins us as a Division Manager for our Geotechnical Group. Mr. McDermott has more than 30 years of geotechnical construction experience, with a […]
As Dr. Petley noted in his blog post, this looks like a classic planar rock slide where the rock mass failed parallel to the dominant planar discontinuity set. The slide occurred on Highway 70 between […]
ENR’s annual top 500 design firms list for 2017 is out. These rankings are based on revenue for design services in the previous calendar year. Last year I extracted a subset of the list to see rankings of firms that are strong in geotechnical / geological related services, so I decided to do it again this year. I included firms that self-identified as geotechnical firms, as well as engineering firms that I know to have a strong geo emphasis. I’m sure there are some that I missed. I also included some of the major A&E firms that provide these types of services. Accordingly, it’s still a bit subjective on who is included. So here is the list of top Geo-Companies of 2017 (along with their change in ranking relative to 2016):

A 20 foot section of a tunnel collapsed at the PUREX facility at the Department of Energy’s Hanford Nuclear Site in Washington State. The PUREX facility was used to extract plutonium for weapons from spent […]
I saw this device (well, a model of it and a presentation) at a recent geotechnical conference and I was very impressed. One of the challenges with the QC of drilled shafts is that you […]
A secondary landslide on Highway 101 north of Legget, California was captured on video at the end of April. The original slide closed the highway and after Caltrans was able to clear it and reopen […]
The International Society of Rock Mechanics (ISRM) has some great lectures posted online. The latest one posted in April is ‘Why Rock Mechanics and Rock Engineering?’ by Professor Emeritus Charles Fairhurst of the University of […]
