El Paso, TX (KTSM) On the eve of demolition weekend, the crews at City Hall continue to work around the clock.

Right now they are preparing the basement area, along with the fourth and eighth floors, making 410 holes total in the supporting structure, said Controlled Demolition, Inc. President Mark Louizeaux.

That is where they'll stick 214 pounds of explosives, made of nitroglycerine.

That Sunday morning, the official countdown begins right at 9 a.m. That's when the public will hear the first horn, signaling the 2-minute warning.

That horn will sound off again, at the 1-minute warning.

Then just before 9:02 a.m., the command center will begin its 15-second countdown, said Louizeaux.

But do not expect the big fall then.

First, you'll hear the initiation charges, then a four-and-a-half-second pause, said Louizeaux.

Then, the main charges will go off, and that'll be the start of the end, he said.
