On Wednesday, the 13th of December, after nearly two years of taking pictures of Comcast Center's construction progress, I had the chance to visit the
site, tagging along with a couple guys representing the firm installing the tuned liquid column damper (TLCD), the largest of its kind in North America.
The TLCD prevents the building from swaying in the wind. They were on site to do readings and testings, so we went to the highest possible level, the
33rd floor. (Though the steel frame is up into the 40s, the floor plates were only available to non-labor to 33.)
