Greenpeace activists have brought work to a standstill on BDP's £27.9 million Lotteryfunded renovation of Glasgow's Kelvingrove Art Gallery.
The direct-action environmentalists say they invaded the site after discovering the flooring contractor was using endangered Malaysian hardwood.
At 8am on Monday, 100 activists walked on to the site and replaced the Merbau wood, provided by supplier Junckers, with other timber, a move that led Glasgow council to order contractors to stop work.
Greenpeace activist Belinda Fletcher described the operation as a success. 'We are delighted that the gallery has agreed to suspend the contract for flooring after the endangered wood was found at the site, ' she said.
BDP has, however, refuted claims about the wood, providing the AJ with a copy of a Malaysian Timber Industry Board certificate vouching that the wood is sustainably sourced.
'The outcome of an investigation by Junckers into the origins of the timber is now awaited, ' a BDP spokesman said. 'Should it prove to be unsustainable the flooring will be replaced.
'BDP is committed to using wood from environmentally sustainable sources and has acted in good faith.
'BDP's timber flooring specification was shown to Greenpeace on site at Kelvingrove during the demonstration.
Greenpeace agreed that this was perfectly OK, ' he added.
