New £17m contract awarded to upgrade Glasgow Subway
A £17m contract to upgrade the Glasgow Subway tunnel lining is expected to be handed to Telford- based Freyssinet Ltd.
The operations committee of Strathclyde Partnership for Transport (SPT) will be advised to grant the contract to the company, asking it to carry out “a programme of targeted and prioritised tunnel lining works including water sealing, void filling, lining repairs and trackbed repair”.
The contract is the largest single award to date under the £300m Subway modernisation. The work will begin early this year, pending contractual approval, and is expected to last two to three years.
Most repairs will be undertaken in tunnels running from Hillhead
station in the west end to Buchanan Street station in the city centre, a stretch which also incorporates Kelvinbridge, St George's Cross and Cowcaddens stations. Another high priority is a section of tunnels on the south side of Glasgow between Shields Road and Kinning Park.
SPT said it would keep disruption “to a minimum” but could not rule out some impact on passenger services. Most repairs will be carried out when the Subway is not running. The operator chose not to do a full watersealing and re-lining of the entire tunnel, as this would necessitate full-scale shutdowns of the system, which was not considered viable.
The report also says Freyssinet “was able to demonstrate that they have considerable experience
of undertaking works of this nature” and that their £16.8m bid was the “most economically advantageous”, ahead of costlier submissions by Balfour Beatty and BAM Ritchies.
SPT chief executive Gordon Maclennan said: “This is a
significant investment to ensure the Subway tunnels remain robust for the future.
“The spend reflects the huge logistics involved in this intricate work within the unique size, shape and composition of the Victorian tunnels themselves.”
