An integrated joint venture between Ferrovial Construction and BEMO (Ferrovial BEMO JV) has been chosen to deliver the £230M design and build contract for the Grain to Tilbury electricity infrastructure upgrade project for its new client, National Grid.
This significant new scheme, involving the boring of a 2.2km tunnel and includes two 35m deep shafts (15m and 12m diameter respectively), headhouses and Cable Sealing End (CSE) compounds, will run from early 2025 until Q1 2029.
The project is part of a broader suite of infrastructure upgrades and reinforcements planned by National Grid as part of The Great Grid Upgrade, the largest overhaul of the UK’s electricity network in generations.
Ferrovial BEMO JV will employ advanced engineering techniques and state-of-the-art technology to ensure the highest standards of safety and efficiency.
One of the solutions to be employed on the scheme is a Vertical Shaft Sinking Machine (VSM). The VSM technology allows for simultaneous excavation and installation of the final lining from the surface, significantly reducing construction time, minimizing environmental impact and ensuring the highest level of safety throughout operation. The VSM can be used under groundwater, making it ideal for the Grain to Tilbury project. This will only be the second time that this method is used in the UK
