Keystone Towers demolished - 13 WTHR Indianapolis

Keystone Towers demolished

Posted: Updated:

INDIANAPOLIS - In less than 14 seconds, a north side Indianapolis eyesore became history Sunday morning.

After months of planning, Keystone Towers was demolished. The demolition involved detonating explosives in two buildings.

The city is paying Denney Excavating $827,000 to demolish the blighted apartment complex. Denney hired Advanced Explosives Demolition to handle the implosion, and Denney will carry out the task of sorting through and removing the rubble.

Six-year-old Eliya Kelly, daughter of the owner of Advanced Explosives Demolition, led the countdown and the plunger was pushed at 8:00 am. Both buildings came down in less than 14 seconds total. An elevator shaft remained standing, which was expected.

Jack Tapp, WTHR's Technical Services Manager, took the lead in setting up WTHR's "implosion camera" inside the building. It's a Sony surveillance camera with a fixed lens encased in aluminum housing to protect it as much as possible from flying debris.

Working with demo crews, Tapp installed the camera on the top of the office building facing northeast, a strategic move meant to give viewers the biggest bang for their buck.

Tapp used 1,000 feet of video cable and a power inserter so the camera could be powered remotely with the video recorded in our live truck.

As for the fate of the implosion camera? "I've asked the implosion guys to return it if they find it. All the engineers signed the outside of the housing and there's a phone number to call if someone finds it and a reward," Tapp said.
