The deal to finish off the Leven bottling plant and new cooperage at Cambus near Alloa were among the biggest prizes up for grabs on Rok’s books.

Steelwork is already up at both sites so the novated work is expected to be worth around £24.5m to ISG.

The deal should bring better long term benefits presenting ISG with a golden opportunity to put the project back on track and establish strong working relations with a big UK client.

Diageo and ISG will now be working together closely to ensure the projects are completed in line with their original time schedules.

The bottling plant build is due to finish next summer, ready for the internal fit-out. Once complete, the new plant will take Whisky production at the site to more than 30 million cases a year and provide some 400 additional jobs.

Diageo Scotland managing director, Bryan Donaghey, said: “We are delighted to announce the appointment of ISG to continue on the good work that Rok  commenced on our construction projects at Leven and Cambus.

“The insolvency of Rok was very unwelcome news both for us and for the many employees and contractors impacted by this highly unfortunate situation.

“Everybody loses from company failures such as this, and our priority now is to continue these projects through to a timely and successful conclusion.  We are confident ISG will be a very valuable partner in achieving this goal.”

Craig Tatton, ISG’s UK Construction managing director, said: “We are delighted to be working with Diageo to bring the Cambus and Leven projects to successful completion in line with original plans.

“We have been able to offer continuity by drawing on the existing expertise and experience in Scotland and that was a considerable asset in securing this contract.”

“On top of our recent expansion across the UK, this announcement coincides with our strategy to grow our operations in Scotland. As part of our plans we are committed to providing new employment and local business opportunities.”
