These are some of the recent projects our teams have been working on in Bristol, Dorset, Somerset and Wiltshire.
Building a "super sewer" in North Bristol
A large tunnelling machine has completed a five-and-a-half-kilometre journey deep under the streets of Bristol to create our new super sewer that will support population growth in the city for decades to come.
The specialist machine, which has worked its way underground from Lawrence Weston to Almondsbury, was specifically chosen to minimise traffic disruption and environmental impact that would have been caused if open trenches were dug to lay the sewer.
After starting its journey in June 2020, the machine has travelled deep underneath built-up areas of Henbury, the former Filton Airfield, Cribbs Causeway and the M5 motorway, all with minimal disturbances to residents, businesses and motorists. Its final destination was the Bristol Golf Club in Almondsbury, where a reception pit was excavated to remove it.
The new sewer is a £55million investment to support ongoing and new development and minimise the risk of flooding and the use of storm overflows during wet weather.
The next phase of the project now that the tunnel is complete is to fit out the new sewer with mechanical and electrical equipment, before removing the various construction sites in Lawrence Weston, Henbury, Filton and the golf club and reinstating the areas back to normal. The project is expected to be fully completed by Autumn 2022.
