Four windows in the Scottish Parliament building must be replaced after manufacturing defects in the glass caused them to crack when they expanded and contracted during hot and cold weather, NCE can reveal this week.
In a statement a Scottish Parliament spokeswoman said: 'In February, a window pane in the Chamber was replaced owing to a manufacturing defect. Three panes have also subsequently cracked and we are awaiting their replacement later this month.'Once removed, these panes will be tested to establish if they suffer from similar manufacturing faults.This latest problem at the Scottish Parliament is being tackled alongside ongoing work to beef up faulty connections to roof struts in the Chamber, after one swung free from its nodal connection (NCE 9 March).Controversy has dogged the project, which was completed in October 2004. Costing £431M the final building was 10 times more expensive than the original £40M estimate (NCE 7 October 2004).The statement continued: 'The glass in the original pane cracked due to thermal shock, the root cause of which was a fault with the glazing, which occurred during manufacture or installation. Once these three panes in the Debating Chamber have been removed they can be tested to confirm the cause.'Work continues on installing stainless steel dowels to secure the Chamber roof struts before the building reopens on 6 September. The spokeswoman said the Scottish Parliament will be seeking compensation for the cost of dowel installation and window replacement, but was still deciding on how best to do this. 'The priority is to get the work done first,' she said.Subcontractor Mero was responsible for the design and installation of the windows. Main contractor for the Parliament was Bovis Lend Lease. Lead designer was Arup.Related links:Today's top stories
