QuadConsult was commissioned by long-standing client steelwork fabricator Dollcast Ltd for the design of the steel frame for the new Aircraft Maintenance Facility at Valley, Anglesey.

The image shows the form of the steel frame to the building which comprised two principal sections:-

• 30m span portal frames at various grid spacings to suit the architectural needs and
• 15m span crane building using a braced steelwork frame.
• Both roofs were curved and following schemes looking at the most cost effective rafter solutions, cellular beams were selected to achieve sway stiffness of the portals and to economise on the fabrication.
