Light End Tunnel After Corecut Complete Work Glasgows Queen Street Upgrade

Corecut, a Scottish concrete contractor, has finished critical infrastructure work on the £60 million Glasgow Queen Street Station tunnel upgrade.

Story Contracting chose the drilling specialist to lead the removal of 10,000 tonnes of existing concrete slabs as the station’s tunnel underwent significant improvements after being awarded the track-slab replacement contract for the Edinburgh to Glasgow Improvement Programme (EGIP).

Broxburn-based Corecut, known for its work on large-scale construction projects, was chosen as the ideal partner for the £1.25 million project, which included diamond drilling and concrete floor sawing in difficult, time-critical tunnel conditions.

Corecut was involved in the project’s planning for nearly two years before beginning the work from March 20 to June 26, including on and offsite trials.

The West Lothian firm approached the project in stages.

The first was pre-blockade work, which included Diamond Drilling of nearly 8,500 112mm diameter x 500mm deep holes to allow subsequent use of Hydraulic Bursting equipment to crack the slab, and 2,750 metres of Tracksaw Cutting to both the up and down lines to separate the concrete slab track from the walls.

The second phase began on April 11 and included major blockade works such as Longitudinal Sawcuts and Hydraulic Bursting, which is one of the safest and most efficient methods of removing reinforced or mass concrete, brickwork, or natural stone.

It also used remote-controlled Robolition demolition equipment to remove 10,000 tonnes of existing concrete, breaking it down into manageable sections for train removal.

Corecut drilled 3,500 holes to a depth of up to three metres during the installation of the new concrete slab, assisting in the anchoring of concrete to bedrock.

A network of dedicated contractors replaced 40-year-old tracks, installed power lines, and expanded platforms ahead of the overall project’s expected opening today (August 8).

Finlay Crocker, Managing Director of Corecut, stated, “The Queen Street tunnel represented a significant challenge for our team, which worked tirelessly on a 24/7 basis in difficult conditions for nearly 100 days from late March to late June.”

“With the difficult environment and tight deadline in mind, we are especially pleased 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 by doing so, we provided a significant boost to the project’s immediate progress in the lead-up to the August 8 opening.”

“We hope that our contribution to Queen Street lays the groundwork for greater success, both for those still working on the project and for the station’s long-term viability.”

“Quality, precision, and continuous innovation are at the heart of every stage of our operation and are fundamental components of our culture as we strive to deliver the best solutions possible.”

“It was a fantastic effort throughout by everyone involved at Corecut,” said Eddie Esdale of Story Contracting, project manager for the location scheme.

“A very innovative solution was proposed and delivered, and the project may not have progressed as smoothly as it did if it hadn’t been for it.” A professional approach from all operatives on site ensured that the works were completed safely and ahead of schedule.”
