Upgrading bond Street
29 June, 2017
London Underground Bond Street Station Upgrade Project (BSSU) is due for completion and open to public in April. In December’s British Tunnelling Society Meeting, the project was told from the perspective of the SCL designer and the contractor working in a one team environment. Through innovation and utilising the latest technology they pushed the SCL design boundaries and developed a safe system of work by minimising the impact on infrastructure while optimising the excavation times to create necessary additional underground space. The speakers were Richard Watts, project manager, London Underground; Steve Nuttall, project director, Color; Andreas Spiegl, principal tunnel engineer, Dr Sauer & Partners and senior SCL engineer on site
