Overview

London Power Tunnels (LPT) is National Grid’s £1bn investment to ensure a continued safe and secure supply of electricity to the capital, by rewiring London via underground tunnels. This talk will focus on LPT Phase 2 and the 32.5km of tunnel and 8 shafts constructed as part of Package 2 “Tunnels and Shafts”. The speakers from National Grid, HMJV, and WSP will outline and discuss the significant achievements realised, challenges overcome, and the ultimate success to date of this significant project.

With tunnel boring machine (TBM) removal from a live NG site, mobilisation during COVID, contamination, historic obstructions, and challenging groundwater conditions there was plenty to keep the team occupied. They still found time however to use Modern Methods of Construction to drive efficiency, cement free concrete, InSAR, artificial intelligence tools, and trial automated ring build. All this whilst engendering a pro-active health, safety and wellbeing culture, as well as leaving a positive legacy with the local communities. 

All design and construction milestones have been delivered on or ahead of programme, and the project remains on budget, a testament to the Project 13 principles adopted by the team.

Following the event, there will be a networking session with food and drinks at ICE Kendal's Cafe, sponsored by HOCHTIEF-MURPHY Joint Venture (HMJV).
