Construction to stablise Glasgow School of Art's fire-ravaged Mackintosh building has fallen behind schedule.

Bad weather has been blamed for the works' completion date being pushed back. 

Art school chiefs had perviously said would be completed by the end of this week but have now pushed the date until October 21.

The new comes as a blow to businesses who have been locked out of their premises since the fire. 

The Centre for Contemporary Arts (CCA) has been sealed off due to a safety cordon since the art school campus caught ablaze for a second time on June 15.

The CCA, which houses 18 businesses and institutions under its roof, still falls under the safety cordon because of a fire exit on Scott Street as workers seek to stablise the Mackintosh's charred west wing.

Other local businesses Bagel Mania, News 4U and Paint & Mortar are also affected by the delay.

Glasgow School of Art (GSA) said contractors have been working "flat out" to stabilise the building, but in the last week two days were lost because the cranes cannot be operated in high winds. 

With Storm Callum approaching Scotland, more bad weather is expected over the next few days.

Professor Tom Inns, director of GSA, said: "Our teams have been continuing to work flat out to complete the work on the west gable of the Mackintosh building, but the bad weather means unfortunately this cannot be done by October 14.

"We want to keep the delay to a minimum, but safety has to be the priority. The cranes have been working and will continue to work whenever there is a window in the weather, but they cannot be operated safely in high winds.

"Weather permitting, we now hope to have the work finished by October 21.

"We have been in touch with affected businesses and we are very sorry for the delay and the obvious, continued impact this will have on them."

The fire in June came as reconstruction following an earlier blaze in the Charles Rennie Mackintosh-designed building in 2014 neared completion.

Art school chiefs have pledged the building will be rebuilt.
