A Broxburn-based Diamond Drilling specialist has revealed that it drew upon almost the entire range of its services during a challenging six-year stint to deliver the record-breaking Queensferry Crossing.
Corecut commenced work on the £1.35 billion project in December 2011, providing a comprehensive portfolio of skills on what is now officially the UK’s tallest bridge, before completing its contributions in August this year.
In doing so, it gave more than 2,000 man days to the project with no lost time incidents.
Known for its involvement on large-scale Scottish construction projects across almost 40 years – including Glasgow’s SSE Hydro, Queen Street Station tunnel upgrade, Emirates Arena, and Falkirk’s Kelpies – Corecut was considered an ideal partner to undertake highly complex work on the new crossing following previous involvement on the existing Forth Road Bridge.
Across the six year duration of the Queensferry Crossing project, it delivered diverse services such as the Diamond Drilling of test cores into grout piles for integrity testing at the start of the construction phase, Hydrodemolition of numerous structures to facilitate modifications to existing approach structures, and Floorsawing to approach roads to facilitate the integration of the new road layout.
Corecut further undertook the drilling and installation of thousands of resin anchors and dowel bars, underwater Wiresaw Cutting in conjunction with divers to divorce redundant temporary tower crane piles from the seabed, emergency controlled demolition of failed sections of concrete using Robolition equipment, and many more services, amounting to some 90% of the company’s wide range of solutions.
Corecut believes that its extensive work on the bridge – totalling a value in excess of £750,000 – has demonstrated the significant benefits of its multi-skilled business model.
The Queensferry Crossing is a globally unique project, forming the centrepiece of a major upgrade to the key cross-Forth transport corridor – the largest Scottish infrastructure project in a generation – and Corecut was confident of delivering results in a highly challenging, often hostile, environment.
The 2.7km long structure is the longest three-tower, cable-stayed bridge in the world and also by far the largest to feature cables that cross mid-span – a design which benefits from extra strength and rigidity.
The new bridge also benefits from windshielding that should almost eliminate the need for closures during frequent high winds.
Furthermore, cables can be replaced with more ease than on the existing Forth Road Bridge, with this being done as part of normal maintenance work without closure.
The crossing became operational on August 30, and was officially opened on September 4 by the Queen – exactly 53 years to the day from when she opened the Forth Road Bridge.
Managing director of Corecut, Finlay Crocker, said: “The fast track construction of the Queensferry Crossing represented a significant challenge for our team, one that demanded an immense effort and the deployment of our full spectrum of capabilities across an extensive six year period.
“We believe that our contribution was a significant and vital one, with the results being testament to the quality, skill and work ethic of all those involved, culminating in what will undoubtedly become one of the world’s great bridges and will be viewed within our company as one of our largest and longest projects.
“Quality, precision, continuous investment and innovation sit 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 to our clients.”
