The project, which got under way in October 2006, includes the construction of a clear span Exhibition Centre and Atrium covering 5,583m², which will be linked to existing facilities, giving an overall covered area of 14,000m².
Steelwork contractor D A Green & Sons, working on behalf of main contractor Linpave Building, will complete steel erection at the end of June.
The Exhibition Hall is 100m long and 60m wide, and the spans are formed from 3 x 20m-long beams.
D A Green Contracts Manager, Ian Burchnall, said the best way to construct the spans was to erect the two end sections on temporary props and then lift in the middle piece between them to allow the required preset to be achieved. The Hall is also formed by a series of 20m-high 508mm diameter CHS’s, spaced at 10m intervals, which support the braced roof via 90mm diameter pin joints.
The Atrium also features a 5t rooflight frame (pictured above) which was delivered to site in two sections, bolted together and then lifted into place in one piece.
