Transport
Crossrail was a major transit line development project in London. This significant infrastructure created a new underground railway line (The Elizabeth Line) running across the capital from east to west. It is one of the city’s largest infrastructure project this century. The Elizabeth Line was opened on 24 May 2022 by Her Majesty Queen Elizabeth II.
Exyte Hargreaves was contracted to design, manufacture, deliver and install 25 individual ventilation systems / 54 transition pieces across five separate sites on the Crossrail network including Canary Wharf and Bond Street. These transition pieces are vital in managing air flow within the tunnels.
These ventilation systems provide fresh air flow into the Crossrail tunnels during normal operation but also have a safety function providing smoke extract in the unlikely event of an emergency.

Given the space restrictions involved with an underground project, Exyte Hargreaves had to utilise intelligent digital design and construction methodology to enable it to deliver the systems effectively
Our approach focussed on 2 aspects of the project to overcome the challenges. Firstly, logistics to the location (through tight London streets) and secondly, the installation of fans and transitions in vertical shafts with very little room for manoeuvre.
Completed: 2019 | Project Value: £1.4 million
Farringdon was one of several stations to receive a major upgrade in facilities. Exyte Hargreaves was awarded the contract to supply and install both DW144 and fire duct for 16 different systems, covering both the East and West ticket halls. Our bespoke system for 200m of duct fitted in the passenger concourse, had to account for the curved profile and restricted space of the tunnel structures. The duct was situated in the ceiling void between tunnel walls and ceiling panels.
We engineered innovative solutions to help progress the project. This included utilising internal jointing to overcome the severely restricted access of some parts of the installation, and devising novel ways of providing the necessary loading support.
"Crossrail was London‘s most ambitious infrastructure project to date at the time. The Elizabeth Line connects the capital with Reading in the West and Shenfield in the East. Exyte Hargreaves completed its contracted work in early 2019. On the back of its work on the Crossrail C610 project, we were awarded Contractor of the Year at the 2018 BESA North West Awards."
