FIREFIGHTERS battled a blaze at Glasgow's new £824million hospital just two days after fire ripped through the Hydro.

The fire at the new South Glasgow Hospital started in a water tank room on the second floor of the under-construction building, which is expected to open in 2015 to replace the existing Southern General Hospital.

Emergency services were alerted to the blaze at the Govan site shortly after 1pm yesterday.

A spokeswoman from Scottish Fire and Rescue said the blaze was put out quickly but firefighters stayed on site to assess the damage and carry out enquiries.

Work started on the project, which will be one of the largest acute hospitals in the UK, in 2010.

Meanwhile, SECC bosses are battling against the clock to try to complete the fire-hit Hydro in time for Rod Stewart to take the stage in three months time.

A rubber roof element used to help keep the new £125m entertainment complex water tight was ignited by a spark as welding operations took place on the roof on Saturday.

The SECC which owns the Hydro has launched a probe and chief executive John Sharkey says it could be more than a week before it's known whether Rod Stewart will still be able to perform the official opening on September 30.

He told how welders had been working on the roof on Saturday when a spark set fire to a water proof membrane fitted directly below the arena's aluminium guttering. The wind is then thought to have fanned the flames which spread rapidly.

SECC bosses have launched an investigation, but Mr Sharkey insisted he was leaving it to "the professionals" to give a detailed assessment of the fire and water damage caused.

As the probe continues, Mr Sharkey admitted he didn't know whether or not the scheduled opening concert will have to be delayed. He insisted: "It's too early to say.

"I don't want to be optimistic and I don't want to be pessimistic. It is our aim to try to open on the day as planned, but it will all depend on what the professions tell me once they have had time to assess the damage.

"Completion wasn't due until the end of August, so there is still time. This is a 24-hour building site. We had a full shift in today. There is other work being done while the investigation goes on."

Mr Sharkey said that regular updates for the public will be given on the Hydro's Facebook page, and added: "This has been one of these really, really unfortunate incidents."
