We undertake projects in the energy landscape, delivering a range of solutions across the electricity and gas sectors. Our expertise covers everything from design and development to installation, maintenance and repair, whilst our work often involves early contractor involvement and collaboration with all stakeholders to provide single sector solutions or integrated packages.
We have an impressive portfolio of successfully completed energy projects, including expertise in the fields of high voltage sub-stations, high voltage cable tunnels, and both high pressure transmission and medium pressure distribution gas pipeline projects.
Examples of our work includes:
- the London Power Tunnels project where we sunk 16 shafts and bored 33km of 3m and 4m diameter cable tunnel under the streets of London;
- the South-East Electricity Sub-station Alliance (SEESA) project to upgrade National Grid’s electricity transmission network in the South of England;
- the North London Gas Alliance and tRIIO schemes to replace a large proportion of the gas mains across part of the capital;
- the River Humber Gas Pipeline Replacement Project where we are currently replacing a 5km section of National Grid’s high-pressure gas transmission pipeline across the Humber estuary via a new tunnel under the riverbed.
