Who’s picking up good vibrations?

Don’t worry. That shaking you feel isn’t an earthquake. It’s the construction of the new Tappan Zee bridge across the Hudson River north of New York. I’m kidding of course. Construction on the $3.9 billion project hasn’t even started yet, but much of the geotechnical work, not to mention the design, has. Now they are planning on picking up good vibrations with highly sophisticated shoebox-sized sensors posted around the construction site. This is nothing new, but the plan to make the data available online 24/7 is–at least as far as I know. Check back here in a few weeks to see the monitoring page.

But lest you think that the only people interested in the movers and shakers at the bridge are the contractor and the nimbies and gadflies nearby, note this: Columbia University’s Lamont-Doherty Earth Obversvatory is just downriver on the West side, home to gobs of the largest and most sophisticated earth measuring equipment you’ll find. My geotechnical engineer friends tell me that every year Lamont-Doherty hosts an open house, which is generally geared toward kids, but is fascinating for geeks (like me) of all ages. It’s usually in early October, so check their website if you’re anywhere near New York and take the kids. While you’re there you can swing by and see a pretty cool construction site at the new bridge.
