National Grid to tender for three cable tunnelling projects

London power tunnels

National Grid is looking for supply chain partners for three tunnelling projects across the UK.

The cable tunnel projects are a 33km London Power Tunnels, a 4km Menai Tunnel in South Wales, and a 3.3km tunnel in Snowdonia in North Wales.

National Grid is calling on all potential supply chain partners to express an interest to participate in a pre-procurement early market engagement process (EME), ahead of the invitation to tender for the cable tunnelling projects and associated infrastructure.

Firms from across the supply chain with relevant infrastructure project experience, and who are typically involved in the design, manufacture, supply, installation, construction and commissioning of cable infrastructure projects, are invited to express an interest. Including shaft and tunnelling contractors, tunnel boring machine manufacturers, concrete segment manufacturers, and tunnel ventilation contractors.

Earlier this week, the National Grid launched the public consultation process for the second phase London Power Tunnel project. The first phase of the project opened in February. 

Anyone wishing to express an interest for the pre-procurement EME must request a pro-forma document and submit it no later than midday on Friday 27 April.

The current estimated date of publication of the contract notice is Monday 2 July 2018.
