You know how it feels good to clean off your desk and have a fresh start? I've collected a number of articles over the past 6 months that I didn't get a chance to blog about. As we move rapidly towards 2016, I wanted to start with a clean slate.  There are certainly some gems in here! Hopefully you have some time off over the holidays, and maybe you check this list twice with a drink in hand!

LogitEasy offers mobile geotechnical data collection and log preparation servicesLogitEasy provides a web-based solution for logging boreholes and wells.  You can send them scanned paper logs, or use their electronic form on a PC or iPad to submit the data to them.  For a flat fee per log, they will prepare electronic logs in gINT, LogPlot, or EnviroInsite (well log) formats and submit report-ready PDF logs and/or electronic data files.  They are currently offering a promotion through the end of 2015.  When you pre-purchase 99 logs, you get an iPad Air 2, a LifeProof rugged case, a mobile internet SIM kit, and a $100 mobile internet card.

Head over to LogitEasy.com and click on the banner at the top of the page for more info on the free iPad promotion.   The things I like about their approach to mobile geotechnical data collection is that you can build in the pricing into your project costs, and their solution works offline as well as online, so you can still log on the iPad at those remote project sites.

Nicholson Construction stabilizes pier on I-65 using micropiles and low-mobility groutingPITTSBURGH, PA – Nicholson Construction recently completed emergency repair work to an unstable pier supporting a bridge on INDOT’s Interstate 65. These repairs enabled a 37-mile section of the highway’s northbound lanes to be reopened after a four-week closure.

The highway was in the process of being rehabilitated and widened when the pier was damaged by steel piles driven into the water tight ground below it. The pier began to settle and eventually rotated ten inches.

Nicholson developed a design-build solution that used micropiles to transfer the loads to more stable soils and low-mobility grouting to fill voids and densify the upper subsurface layer.

[Editor] Read on to hear more about Nicholson’s fix of this unstable bridge pier. [/Editor]

This is pretty cool! It's not every day that you have a major Hollywood motion picture that features drillers as the unlikely heroes! The movie 'The 33" stars some big names like Antonio Banderas, Lou Diamond Phillips, and James Brolin as the driller extraordinaire, Jeff Hart.
