Ramboll selected to upgrade St Pancras International station

Ramboll has been appointed by the recently re-branded London St Pancras High Speed (LSPH) to support substantial upgrades at St Pancras International, one of London’s most prominent transport hubs, as part of plans to increase passenger capacity and enhance operations for international rail services.

As part of the project, Ramboll will be providing multi-disciplinary services including structural engineering, MEP engineering, sustainability consultancy, border control consultancy and historic structures. The company’s cross-sector experience will be key to the success of this complex project, which will be measured by the maintenance of operations and great customer experience throughout the upgrade.

Ramboll alongside architects Hawkins\Brown worked together to select a specialist team of subconsultants to ensure the proposed design team had the correct blend of skills, experience and a proven track record of successful collaboration. Together, the group will deliver feasibility and concept design for a reconfigured international departures area.

The appointment follows a competitive tender process and marks the next step in LSPH’s long-term vision to ensure the station can accommodate future demand. Passenger numbers are expected to rise significantly, with Eurostar aiming to increase capacity from 1,800 to 2,700 passengers an hour, and new international train operators set to run services alongside Eurostar in the coming years.

Originally designed by William Henry Barlow and opened in 1868, the Grade I-listed station underwent an £800 million refurbishment in 2007. However, changing travel patterns, new post-Brexit border checks, and growing international rail demand have led to capacity constraints.

Commenting on the appointment win, Ramani Armstrong, Director at Ramboll said: “We are delighted to be selected to be part of the design team for this iconic heritage grade I listed building. This project perfectly aligns with our mission to be the partner for sustainable change through the enhancement of a key transport hub to provide a sustainable alternative to air travel. We’re passionate about respecting, reviewing and renewing existing buildings, which is key to creating a sustainable built environment. This is a building that is beloved by many Londoners and travellers, and we are so excited to make the experience of all those who use it even more positive.”

LSPH, which operates the 109km high-speed line between London and the Channel Tunnel under a 30-year concession, launched its capacity upgrade programme in January. This new phase will develop design and operational concepts that could serve expected growth through to 2035 and beyond.
