Subway tunnels

£17 million tunnel improvements for Subway

£17 million of tunnel lining improvements to the Subway’s tunnels has been approved at today’s (Friday 19 December 2014) Partnership meeting.

The award of a contract to Freyssinet Ltd for £16,760,427 was agreed at today’s meeting of the SPT Partnership. It is a vital component of infrastructure upgrade works by SPT to improve the network’s infrastructure, ensure the integrity of the tunnels for future and to minimise on-going maintenance costs.

The significant investment by SPT will ensure the Subway tunnels remain robust for the future and will be a key part of on-going activity to modernise the entire system. To minimise disruption, the work will be undertaken at night when the system is closed to the public.

The tender submission by Freyssinet Ltd also includes plans to introduce a minimum of five apprenticeships during the project’s delivery with further details to be announced in 2015.

SPT Chief Executive Gordon Maclennan said:
“This is a significant investment to ensure the Subway tunnels remain robust for the future and the delivery of new rolling stock. The spend reflects the huge logistics involved in this intricate work within the unique size, shape and composition of the Victorian tunnels themselves.

“There will be challenges for SPT delivering the work within the limited time available when trains are not running at night but the improvements are an essential part of our preparations for new modern trains and new signalling.

“The work will strengthen further the existing tunnel lining, reduce water ingress and importantly, cut down on long term maintenance costs.

“We’re delighted too that the contract includes a proposal for an apprenticeship scheme as this offers great experience in a very specialist market.”

The scope of work will focus on the following sections of tunnels in the Subway network with remaining areas requiring less intrusive remedial work:

Kevinbridge to St George’s Cross; Cowcaddens to Buchanan Street; St George’s Cross to Cowcaddens; Hillhead to Kelvinbridge and Shields road to Kinning Park.

The Award of contract will be subject to satisfaction of the requirements of the mandatory standstill period for EU advertised public sector contracts. Following that the work will commence in the early part of 2015.
