Successfully managing Covid-19 on tunnelling operations for the Thames Tideway Tunnel, UK

Christina Trigle · Proceedings of the Institution of Civil Engineers - Civil Engineering · 2022

The Covid-19 pandemic had a huge impact on the way the UK population lived and worked during 2020. This paper explores the challenges faced while boring the west section of the Thames Tideway Tunnel in London, UK, with particular focus on the first national lockdown that began in March 2020. It discusses how the reduction in personnel triggered closure of the site, the technical challenge of safely stopping a tunnel boring machine for extended periods of time and the practical difficulties of creating a Covid-safe environment in a challenging space. This case study can be used to inform other underground construction projects coping with coronavirus.
