Containment device for contaminated building demolition

Abstract

A containment device for contaminated building demolition. A pre-engineered rigid steel frame building is supported on rail trucks movable on railroad tracks. The railroad tracks are positioned on opposite sides and along the length of the contaminated building to be demolished. The rigid steel frame building has one open end and is sized larger than the width and height of the contaminated building. This allows a portion of the contaminated building to be movably enclosed by the pre-engineered building. A flexible liner material inside the pre-engineered building, at the open end attached to the contaminated building, and at the bottom of the pre-engineered building draped to be in contact with the ground seals off the interior of the pre-engineered building to prevent the release of contaminated particles during demolishing operations. A hoist and cable are used to move the pre-engineered building on the railroad tracks. After the covered portion of the contaminated building is demolished and the area remediated, the pre-engineered building is moved on the railroad tracks to cover another portion of the contaminated building. The process is repeated until the contaminated building is completely demolished.
