Crossrail station Abbey Wood

A free-form design unlike any other: Abbey Wood station in London is reminiscent of the shape of a ray. Construction of the station was a challenge - even for experienced timber engineers.

Single-curved primary supports and double-curved secondary supports made the construction possible WIEHAG implemented this unique project in London with its product and solution expertise.

Task

A sophisticated free-form

The Abbey Wood station is the terminus of the Crossrail line and has the shape of a ray. This roof form was planned by architects Fereday + Pollard. The roof area extends over 1,600 square metres. "The safety requirements in railway construction in the UK are extremely high and very challenging," explains WIEHAG UK Sales Manager, John Spittle. In addition to high-precision CNC prefabrication of the timber, 30 tonnes of steel were also required for assembling the supporting structure.

Implementation

The complex support structure was implemented as follows

The loads of the mighty timber roof construction are transmitted to a steel structure consisting of beams and support columns. The timber construction can essentially be divided into four components:

Four single-curved primary support members designed as a cantilever girder system, with a total length of 45 m per member.
Single and double-curved secondary supports connected primarily using the WIEHAG WHB system to the primary trusses.
18 straight or single-curved tertiary support members.
Around 1,600 m² of 3-layer natural wood boards made of larch and spruce.
