Sunday blast to drop Thomas Building…

Dallas Demolition making final preparations ahead of weekend implosion.

The clock is ticking for the 88-year old Thomas Building in downtown Dallas. At 10 am Sunday morning (local time), it will be imploded by Dallas Demolition crews.

Eric Lohden, vice president of Dallas Demolition, guesstimates it will take all of 12 seconds to raze architect Anton Korn‘s building, the last vestige of Dallas’ heyday as a cotton-trading town.

This will be the first downtown implosion since Dallas Demolition razed a big hunk of First Baptist Dallas on October 30, 2010, to make way for the expansion that’s filling St. Paul. Lohden says that one used about 600 pounds of dynamite and other explosives; the much smaller Thomas Building will come down with just 300 pounds. And it will be supervised by Eric’s nephew Bond, son of Dallas Demolition president Tony, who says “it’s a fairly small and easy job — not that big a deal.”

Dallas Demolition is also supervising the razing of the Praetorian Building, which, you may recall, was supposed to go out with a bang till neighbors complained about the potential fallout.
