A Broxburn-based Diamond Drilling specialist has completed key infrastructural work on Glasgow’s Queen Street Station tunnel upgrade, doing so on budget and ahead of schedule.
Corecut was singled out by Story Contracting – which was awarded the track-slab replacement contract for the Edinburgh to Glasgow Improvement Programme (EGIP) – to take the lead role in the removal of 10,000 tonnes of existing concrete slabs as the station’s tunnel underwent significant improvements.
The £60million high level tunnel upgrade is considered to be the most significant feat of engineering along the Edinburgh-Glasgow line in 170 years, and Corecut was confident of delivering results in a highly challenging rail environment.
Moreover, at a contract value of £1.25million, it represented the largest Diamond Drilling project undertaken in Scotland to date.
Starting on 20 March, the company worked around the clock, seven days a week, to remove almost a kilometre-long concrete slab track, before concluding on 26 June – a whole six days ahead of schedule.
Corecut was involved in the planning of the project nearly two years prior to undertaking the actual works, including on and off-site trials. Once the tunnel upgrade had fully commenced, it then worked nearly 900 man days on site without a lost time incident.
Upon installation of the new concrete slab, Corecut drilled 3,500 holes to a depth of up to three metres, helping to anchor concrete to bedrock.
Ahead of the overall project’s anticipated 8 August opening, 40-year-old track continues to be replaced, power lines installed, and platforms expanded by a network of dedicated contractors.
Managing Director of Corecut, Finlay Crocker said: “The Queen Street tunnel represented a significant challenge for our team, which worked diligently on a 24/7 basis in difficult conditions across almost 100 days from late March to late June.
“With the difficult environment and tight deadline in mind, it is particularly pleasing to us that we were able to complete the work safely, within budget, and nearly a week ahead of schedule, which is testament to the quality and work ethic of those involved.
“We believe that, in doing so, we provided a major boost to the project’s immediate progress in the run-up to the 8 August opening.
“We hope that our contribution to Queen Street lays the foundations for wider success, both for those still engaged on the project, and for the station’s long-term future.
“Quality, precision, and continuous innovation are at the heart of every stage of our operation and represent fundamental parts of our culture as we look to deliver the best possible solutions.”
Location Scheme Project Manager, Eddie Esdale of Story Contracting said: “It was a fantastic effort throughout by everyone involved at Corecut.
“A very innovative solution was proposed and delivered, and without it, the project may not have progressed as smoothly as it did. A professional approach from all operatives on site ensured the safe delivery of the works ahead of programme.”
Delivering everything from road and rail to tunnel and bridge projects, the company has helped to keep Scotland moving with its involvement on the £500million M8, M73 and M74 upgrade works – including the new Braehead Rail Bridge – the new £1.35bn Forth crossing, the £550million Aberdeen Western Peripheral Route, and the £35million A9 Dualling Programme.
