UK Energy company National Grid has appointed Arup as Programme Manager for its eight year contract for the delivery of two new deep cable tunnel systems in London. The first works contract of this programme has just been awarded by National Grid to contractor Costain for 33km of 4m diameter tunnelling. This US$320M contract includes the design and construction of two new cable tunnels.
“We are highly delighted to be providing the programme management to National Grid on this complex and innovative investment programme to secure London’s future electricity supplies,” said David Twine, Arup’s Director for the Programme Management commission
One tunnel will run east to west, connecting National Grid’s substations at Hackney and Willesden, via St John’s Wood and Kensal Green.
The other tunnel will run north to south, connecting their Kensal Green and Wimbledon substations. The contract award also includes the design and build of associated head-houses and the installation of ventilation equipment.
Speaking of the award, National Grid’s UK Construction Director, Michael Dyke said, “It’s National Grid’s job to ensure we provide a reliable electricity network so people who live and work in the UK can continue to enjoy a safe and secure supply.
“Arup will add to the overall strength of the construction family we have worked hard to create at National Grid.
“This part of our ambitious cable tunnels programme provides a unique solution for London which enables us to execute vital works to replace the existing cable system whilst keeping the lights on, as well as securing a safe means of access to inspect and maintain these cable circuits in the future, with little disruption.”
These new cable tunnel circuits are part of National Grid’s major investment to ensure that electricity transmission infrastructure meets the future challenges of the most densely populated area in the UK.
