Crossrail C405 Paddington Station (Fabrication)

The project involved manufacturing and installing a steel support framework that would hang from the concrete soffit of the station and support the three-tonne concrete smoke ducts anchored to the soffit, whilst also providing the role of the main support for the platform edge screen.
As Crossrail Paddington is an underground station, no cranes or proprietary lifting equipment could be used in the undertaking of this activity due to access restrictions. As a result, Kilnbridge developed an installation methodology that utilised a bespoke manufactured mobile platform complete with scissor table and air skates to allow controlled installation of the precast units and a bespoke designed lifting frame for the PES installation.
Through the use of this methodology, 155 PES frames (circa 800kg ea) and 310 pre-cast smoke ducts were successfully installed to a very tight programme and to meet Crossrail’s exacting standards on both quality and health and safety.
