I will be the guest speaker at an EagleLIFT, Inc. webinar this Friday, September 16, 2016, from 11am-12pm MST titled: "Geotechnical Aspects of Polyurethane Grout". I spoke on this topic about a year ago, but if you missed it then, I hope you can attend! Register at: http://eaglelifting.com/webinar/
I am not affiliated with EagleLIFT or URETEK (although, full disclosure, URETEK ICR is a GeoPrac.net sponsor), but I do consider myself a fan and evangelist of their geotechnical polyurethane products and service. I will be discussing their polyurethane grouting technology from a geotechnical engineer’s perspective. I will cover the modes of ground improvement, improvements in shear strength, and some of the challenges associated with geotechnical characterization. I hope you can make it!
Fugro released their financial results for HY 2016. I'm going to guess that's the Dutch equivalent of FY 2016. It's been a tough year for them it looks like, thanks largely to the depressed oil and gas market. Their sales revenues were down over 25 percent from 2015.

There is a nice little article at the Big Ideas Blog that gives you some insight into the CEO of Moretrench, Art Corwin. Art is unique in this industry from what I can tell in that he wasn't hired from outside to run the company, he came up from the ground floor as a staff engineer with Moretrench, the only company he has worked for in his engineering career. I love his little anecdote about how he aced three exams in an architecture class. The professor asked him if he wanted to be an architect, and said he did. The prof then told him that since he aced the exams, and couldn't draw to save his life, he should become an engineer! I am also impressed by how generous Art is with his time, volunteering for a homeless charity among other things. And that generosity is evident in the Moretrench culture that he helped shape as well. Definitely worth the time to read!

Nicholson Construction was recently awarded a secant pile wall contract for the Maline Creek combined sewer overflow (CSO) project in St Louis, Missouri. Their scope of work will include 78 880-mm (~3-ft) piles to depths of 40 to 50 feet, 114 880-mm secant piles to approximately the same depth that will form a braced excavation. They will also install 4 seven foot diameter jet grout columns beneath an existing sewer to support it during excavation. [Source: More about the project at NicholsonConstruction.com.

The residential high-rise Millennium Tower in San Francisco has settled a total of 16 inches since opening, 2 inches deferentially. A spokesman for the tower owner blames the settlement on the excavation next door for the Transbay Transit Center, a $2.4 billion dollar project being constructed 60 feet underground.
However, the Transbay Joint Powers Authority (Transbay) hired geotechnical firm Arup in 2010. Their initial report indicated that the tower had already settled 10 inches by the time excavation began for the Transit center. Arup seems to have been tasked with design, installation, and perhaps monitoring of a geotechnical monitoring program, some information on the scope is available in a 2012 presentation given by Arup available on the Transbay website.
This is a really nice video for folks new to the industry who want to learn about drilled shafts. It has some great photos and hits the high points of what the advantages of drilled shafts are, a bit about how they are designed, construction methods and considerations, etc. [Source: Pier Research YouTube Channel via PileBuck Magazine.
