New Taxi Facility on Heritage Structures at Paddington

Summary

As a preliminary part of the Crossrail works at Paddington Station, the existing deck spanning platforms and railway tracks is being transformed from a disused goods depot into a taxi and passenger interchange facility. Paddington Station is a Grade 1 listed heritage structure and all modifications to the existing fabric need to be sympathetic to the heritage environment.
The original deck was assessed for highway loading and additional loads from the new structures. A reinforced concrete framed building, constructed c.1920 using the Hennebique system had significant areas of delamination and corroded reinforcement. Surveys and evaluation of current condition generated a prioritised repair strategy. All work has been carried out in and around operational railway infrastructure, within a congested urban site, which has added complexity to both design and construction solutions.
