Another film of the swimming pool being demolished

This is the film shot by the demolition company, Roller Sprengtechnik GmbH & Co. KG from Wuppertal, and kindly provided to show the moment when the indoor swimming pool was blown up:

Altkönigstraße to remain closed, Swimming Pool to be blown up

The Altkönigstraße is to remain closed between the Theodor-Heuss-Straße and Rotbornstraße until Friday, 7th June, 2013, while building work on the new swimming pool takes place.  The diversion will also remain in place.

The shell of the old indoor swimming pool building

On Tuesday, 4th June, 2013 at 11am the remaining shell of the old indoor swimming pool building will be demolished using explosives.  During this time the area will be cordoned off with no-one allowed inside a 150m radius of the building except local residents who are required to stay indoors with their shutters closed and on the far side of the house to the explosion.  Cars should be removed from the area.

The 120m ring of concrete that is left standing is under such pressure, that the structural engineer responsible fears that if diggers where to cut into it, it may release that pressure and break apart uncontrollably.  Instead seven holes have been drilled into each of the supporting legs and these are filled with explosives totalling around 50kg.  The ring itself will be cut at four places by plasma beams at the same time as the explosives go off.

The result will be 4 pieces of concrete each 30m long, which should just fall to the ground if everything goes according to plan.  The 150m safety radius is a precaution in case that does not happen, or if parts of the concrete break off and fly away.  Around 1,000 tonnes of concrete is currently left standing in the shell of the building.

No parking no waiting here during the explosion
