Fugro released their financial results for HY 2016. I'm going to guess that's the Dutch equivalent of FY 2016.

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 [...]

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 [...]

New Solution Saves Money and Time Preventing Loss of Grain and Equipment Damage MOUNT AIRY, NC—Soil consolidation and settlement happens. It’s a fact of farm life. Secondary consolidation slowly forces water out of the spaces between soil particles. As this happens, soil particles move close together and settling occurs. Floors drop and become uneven. Newer grain silos and bins are using concrete floors instead of metal, and as secondary consolidation occurs beneath them, depressed or [...]
