A specialist contracting firm from Stirling has made a splash after completing a £750,000 refit of the penguin enclosure at Edinburgh Zoo.
The Fraser Bruce Group was called in to carry out remedial works at the pool last year after it was found to be losing water.
However, it soon became clear the enclosure was in need of a full overhaul after it was discovered that an estimated 50,000 litres of water was leaking from the pool every day.
FBG contractors spent several months stripping back layers of pool which had been built up over the 100-plus years that penguins have been resident in Edinburgh.
The firm then set about rebuilding the attraction to ensure the birds had the best possible home to return to when they arrived back in the capital last month.
Company founder Fraser Bruce, who hails from Auchterarder, said it had been one of the more unusual jobs his company had undertaken.
Other major projects involving the company which has around 40 staff in total, around half of whom are drawn from the Perth area included waterproofing works at the new public swimming pool being built in Dundee and Stark’s Park, the home of Raith Rovers.
The enclosure has now been renamed and reopened to the public as Penguins Rock.
Mr Bruce said: “We were brought in as specialists to find out where the water was going, and what we discovered was about 11 different layers of pool that had built up over the years.
“There was 100 years of different types of structure and what we had to do was tie in the old with new so both were structurally sound.”
The new enclosure features a remodelled pool, water slide, a fake beach, a waterfall and new viewing areas for the public.
Mr Bruce said he was pleased with the final outcome to the project, but it had been a technically tricky build.
“The random shape of the original pool meant we had to rely on the skills of our specialist labour force to determine the final shape of the new pool.
“There were no drawings to work to and the actual profiling was a free-hand installation using water levels to determine the positioning of the features.”
