Balfour Beatty’s Thames Tideway joint venture with BAM Nuttall and Morgan Sindall announced that a giant tunnel boring machine building part of London’s new super sewer has completed its journey, marking another crucial step towards a cleaner, healthier River Thames. TBM Rachel has now finished tunnelling the western 7km section of the main tunnel after breaking into the shaft at Tideway’s site in Acton. Around 725,000 tonnes of spoil was excavated as part of the drive – equivalent to almost 60 times the weight of the UK’s tallest building, the Shard.

TBM Rachel first arrived in London in November 2017, having travelled 750km by river from the port of Kehl in Germany. After careful assembly, the 1,350-tonne machine was lowered 35 metres into the ground and began tunnelling in May 2019. Working a total of nearly 1,100 shifts, around 200 staff have worked on the western section of the tunnel, with Tideway’s use of the river to remove spoil and bring in concrete segment keeping around 25,000 lorries off the road.

TBM Rachel was named after Rachel Parsons, who was the founding president of the Women's Engineering Society and a former Fulham resident.
