Key points Many have dreamt of throwing a vaenvironmental bubble over outdoor

facilities to design out the Britishweather. But how do you do this fo,/m, without landing your clwith an impractical building andimpossible running and maintenancosts? At the Ravenscraig RegionalSports Facility on the outskirts ofMotherwell, North Lanarkshire,which opened this month, Populouhas distilled the essential elements this vision: daylight, views, >>

Structuraldesign

The main sports hall trusses are constructed fr

column and angle sections with bolted connec

on-site assembly to form the economical struc

roof prole. The football hall trusses span 72m

conguration from at to arched, to form the p

building which reects the internal headroom r

the football pitch. All of the main halls use pro

supported on purlins, with clear polycarbonatenorthlights and the north elevations. The chang

ofce block have a composite beam and colum

to support slabs and at roof decks.

Due to its location on a former steelworks s

works were complicated by the extensive t unn

foundations and underground pipework. Our g

therefore included dynamic compaction and th

and removal of basements and machinery. Thisformation for the ground bearing foundations fo

The technical challenges were demanding a

of long and column-free spaces generated an

innovative structure that is integrated with low

low carbon technologies.

Compliance with re regulationswas problematic, but resulted in somegood design solutions that enhancethe schemes spatial qualities. BryanMorrell, associate re engineer at BuroHappold FEDRA explains: efootball hall far exceeded the maximumre compartment size and, althoughsports activities carry a low re risk,because it had to accommodate eventssuch as concerts and exhibitions itrequired a smoke control system. >>
