London Gatwick: Bachy Soletanche completes foundations for Pier 6 extension<\/h1><\/div>
<\/div>

The extension of Pier 6 at London Gatwick Airport has reached a key milestone. Bachy Soletanche<\/a>, in collaboration with WSP and under the direction of Mace, has successfully completed the foundation works. The goal: increase capacity while drastically reducing the carbon footprint.<\/p>\n<\/div>

<\/div>

A strategic project to streamline passenger traffic<\/h2><\/div>

To address the rise in air traffic and enhance the passenger experience, London Gatwick has launched a major extension of its Pier 6. The project includes the addition of eight new boarding gates, enabling 7.5 million passengers per year to access aircraft directly, without relying on buses. By eliminating over 12,000 shuttle trips annually, this infrastructure will contribute to smoother, more efficient, and more sustainable airport operations.<\/p>\n<\/div>

The works carried out<\/h2><\/div>

Entrusted to Bachy Soletanche, the foundation works took place over a two-month period and involved a Liebherr LB24 drilling rig to install more than 200 continuous flight auger (CFA) piles<\/a> across three platform levels. The in-house design team optimised the geotechnical design by reducing the length and diameter of the piles and the depth of the platforms, thus limiting material use and significantly cutting carbon emissions.<\/p>\n

Sustainability was embedded at every stage. The use of low-carbon CIII\/B concrete resulted in savings of approximately 40 tonnes of CO\u2082. In addition, reducing crane usage helped save 1,500 litres of fuel, and sourcing was done through approved local airside suppliers, further strengthening the low-carbon approach.<\/p>\n<\/div>

<\/span><\/div>

Operating under constraints in an airside environment<\/h2><\/div>

Working in such an environment requires high-precision logistics and strict adherence to safety protocols: specific permits, height restrictions, and multi-stakeholder coordination. To enhance safety and efficiency, Bachy Soletanche implemented innovative methods, including replacing hot works with hydraulic rebar cutters.<\/p>\n

The Pier 6 extension is scheduled for completion in 2027.<\/p>\n

\n

\u201cWe\u2019re proud to have contributed to such a significant infrastructure upgrade at London Gatwick. Despite the complexities of airside working, our team delivered safely, efficiently and with sustainability at the forefront.\u201d
