BAM Nuttall is a UK-based construction and civil engineering contractor and a subsidiary of Royal BAM Group, operating within the Group’s United Kingdom and Ireland division. Founded in 1865 and now headquartered in Camberley, it delivers major infrastructure for public and private sector clients across rail, highways, marine, energy and water. The company has played a long-term role in shaping UK infrastructure, from early projects such as the Queensway, Dartford and Tyne road tunnels and the Liver Building to more recent work on High Speed 1, Crossrail station upgrades, the Cambridgeshire Guided Busway and the Cross Tay Link Road. It is a principal construction partner to Network Rail, delivering schemes including the Levenmouth Rail Link, Inverness Airport station and the Dawlish sea wall, and is involved in major rail programmes such as the Transpennine Route Upgrade and HS2.
BAM Nuttall has established capability across the energy and offshore wind value chain. It constructs onshore civil works for substations and converter stations for transmission clients such as SSEN and Siemens, including multiple sites in northern Scotland and the Triton Knoll onshore substation, and undertakes construction of gravity-base foundations and other offshore structures built on land, for example at the Blyth Demonstration Wind Farm. The company is delivering civils infrastructure for SSEN Transmission’s Shetland HVDC link at Kergord, which will connect island renewables to the GB grid. Its portfolio also includes marine and port works, coastal protection and climate resilience schemes, and long-running frameworks with the British Antarctic Survey to upgrade facilities at bases including Rothera.
The contractor combines a large directly employed UK workforce with extensive use of digital technologies such as Building Information Modelling and, increasingly, 5G-enabled tools, drones, mixed reality and IoT sensors to improve safety, productivity and sustainability. BAM Nuttall has been independently accredited for BIM implementation and is positioning digital engineering and collaborative working at the core of its delivery model. In 2023 it generated turnover of around £1.2 billion, rising to about £1.3 billion in 2024, with pre-tax profits improving strongly and an order book of approximately £4.2 billion, underpinned by strategic partnerships in rail, energy transmission and major civil engineering frameworks.
