Skidsteers and mini-excavators are frequently used in top-down demolition to dismantle multi-storey buildings floor by floor.But it’s a delicate operation which is, by necessity, carried out at height.
The safety risks are clear – and machines have been known to disappear over the edge of the building, along with their operator.As recently as January 2020, demolition contractor McGee was fined £500,000 following the death of an excavator operator who was killed when his machine fell through a concrete floor during a demolition project in central London.So if you can do it without putting a real live human being in the operator’s cab, so much the better.
This is the thinking behind a decision by Kings Langley-based BooBoo Plant Hire to invest in a new remote-control Bobcat S450 skidsteer loader for use on a job in north London for demolition specialist Erith.The project involves the top-down demolition of the five-storey Waterlowe Building, a former wing of the Whittington Hospital in Upper Holloway.
Originally conceived as a job suitable for a high-reach excavator, the site’s extreme lack of space demanded a reassessment. With live hospital buildings at the rear, a primary school to one side, residential property to the other and the busy Highgate Hill passing directly past the front, Erith opted instead to use compact equipment to nibble the building down.
