Hayes and Harlington station serves the west London districts from Paddington Station to Heathrow and forms part of the Crossrail Package 3 upgrade which involves new trains, improved stations and easier, more reliable journeys for passengers in west London. These major upgrades are being carried out by Network Rail at stations on this section of the Crossrail (Elizabeth Line) route in preparation for the start of services in 2020.

Due to program constraints and limited possession availability, Keller UK had to come up with the most effective piling solution and plan that could be used to work within two meters of the rail infrastructure. This meant loading the rig onto platforms during the night, working and then installing Sectional Flight Auger (SFA) piles to the required design depths. With challenging ground conditions, works had to be modified while on-site to ensure piles could be installed to the correct specification. Keller managed to install a number of 600mm, 450mm & 300mm SFA piles to support the construction of new platforms.
