Video Tour of NY Subway Mega-Projects

February 11, 2013 rockman Comments Off

The New York MTA is in the midst of a “golden era” of tunneling for the New York subway. Three separate mega-projects are currently underway totaling some $15 Billion: The Second Avenue Subway, The East Side Access Project (which features the new Grand Central Terminal), and The Number 7 Subway Line Extension Project. The short video below was published by the NY Post and included in an AP Article. It is tantalizingly short, but gives a great perspective on what the underground construction project at Grand Central looks like and a sense of the scale…the amazing huge caverns being constructed. The article says that from underneath Grand Central Terminal alone, the construction crews have removed enough material to cover Central Park almost a foot deep!

32-Person Hot Tub Gets Lift

32-Person Hot Tub Gets Lift

A New Mexico mountain resort recently unveiled their new fitness complex which featured a large indoor swimming pool and 32 person spa. Built on the side of a mountain, on side of the spa structure sits on top of approximately 12.0’ of fill material. When the spa and portions of the deck began to show telltale signs of settlement, the spa was drained and taken out of service, and an investigation was conducted. This investigation revealed a large plumbing leak which had occurred under the pool/spa deck, causing compaction and consolidation of the supporting fill materials. The general contractor on the job broke out a section of the pool deck to make the plumbing repair, and then turned to URETEK ICR for the remediation of the settlement issues.

Management was pleased that the process meant no disruption for their guests. URETEK’s solution was less than 20% of the cost of replacement of the structure.

Shoring wall failure in Rosslyn, Virginia

Shoring wall failure in Rosslyn, Virginia

On Sunday evening, a soldier pile lagging wall shoring system failed at the Sedona & Slate residential development construction site in Rosslyn, Virginia (Arlington County). There were no reported injuries, but an adjacent apartment building was evacuated as a precaution and a nearby street is closed to traffic. Click through for a video that shows some additional views of the damage. The scale of the wall is apparent when you see the shots with workers putting braces near the bottom of the wall. I’m guessing the rakers shown in this image were added monday to attempt to stabilize the wall, but that’s just speculation at this point. Image: MyFoxDC.com

Engineering Geologists vs Geological Engineers vs Geotechnical Engineers

February 23, 2011 rockman 5

So what’s the difference between Engineering Geologists, Geological Engineers and Geotechnical Engineers? That’s not the beginning of a geeky joke. But in most professional circles in this industry, it’s a question where the nuances of the answer seem to be lost on people. My degrees were in Geological Engineering, but I’ve been practicing as a Geotechnical Engineer for most of my professional career. But I get called a geologist, geotech, Civil Engineer, dirty guy…and probably some other things behind my back. I try to explain to people what the differences are, but I’ve struggled over the years to find the right words.
