King’s Cross Underground Station Redevelopment

Zero impact on station operations

Landmark facilities updated

Regeneration of the King’s Cross area

As part of phase II of the redevelopment of London’s King’s Cross underground station, UnPS provided feasibility studies, concept designs and detailed designs for the construction of the tunnelling works.

The phase II project involved the upgrade of the existing station to accommodate the additional passengers generated by the completion of the Channel Tunnel Rail Link terminus at St. Pancras and the regeneration of the King’s Cross area.

We designed works for the pedestrian access passageways to each of the King’s Cross deep level underground lines, Northern, Piccadilly and Victoria. These passageways were constructed using a temporary Sprayed Concrete Lining (SCL) and Spheroidal Graphite Iron (SGI) rings as the permanent lining.
