Crossrail Station Abbey Wood

Project data

  • Location: London, Great Britain
  • Client: Balfour Beatty Rail Projects Ltd.
  • Architect: Fereday + Pollard

WIEHAG built an engineered timber roof structure for another Crossrail station in London. The Abbey Wood station, part of the Crossrail line, take the form of a stingray. The architectural firm Fereday + Pollard created the design, and the Upper Austrian based engineered timber expert, WIEHAG supply the glulam members with a total span of 45 meters. The roof area account for 1,600 m2.

 

Railway construction safety requirements in in the UK are extremely high and very challenging.

In addition to the glulam timbers, which are pre-fabricated using CNC technology, assembly of the roof support structure requires 30 tons of steel. The contract value is € 1.4 million.  Assembly of this exceptional structure commenced in August, and follows in the footsteps of WIEHAG’s other high profile UK projects, which include the Crossrail Canary Wharf station and the Macallan Whiskey Distillery in Scotland.  WIEHAG’s engineered timber projects represent an export rate of approximately 70 percent of total annual sales.

 

 Construction details:

  • Larch and spruce glulam members in “visual quality”
  • 1,600 m2 load-bearing 3-layer cross laminated timber panels
  • 30 tons of steel
  • Roof Dimensions: 50 x 55 m
  • Radii of curvature at primary supporting strands of up to 8 m
  • Horizontal, vertical and truss wind bracing system made of steel
  • Roof structure and roof area of ​​1,600 m2
  • Glulam columns made of larch with steel core

 

Supporting structure:

A grid of steel beams and girders supports the loads of the engineered timber roof structure. The timber roof structure can be divided essentially into four components:

  1. Four single-curved primary support members, designed as a cantilever girder system, with a total length of 45m per member
  2. Single and double-curved secondary supports, connected primarily with WIEHAG brackets fixed to the primary trusses or support structure
  3. 18 straight or simply curved tertiary support members
  4. 3-layer cross-laminated timber panels in larch and spruce, 1600m²

    The components 1-3 are free form with variable deburring at the top edge. The visible beams are in “visual quality.”  Some members are double-curved, however the bulk of the support is single-curved.
