structures for sport
Building a sports hall using precast concrete panels is a speedy alternative to traditional methods of construction.
T
HE NEW sports hall at Chase Terrace Technology College in Staffordshire features precast
concrete wall panels up to 10m high, which were designed to provide structural support and carry the roof. It took 15 days to install the concrete wall panels, removing the need for a steel frame and cladding, brickwork and blockwork. The entire project was completed in 27 weeks. Each weighing up to 10 tonnes, the 120 panels were craned into place to form the perimeter and some internal walls of the 33m × 18m sports hall and adjacent changing rooms, office and fitness centre. Precast panels were secured to reinforced strip foundations using steel

anchors. They were installed by design- and-build contractor Buchan Special Projects, following their manufacture by Roger Bullivant (RBL).
Sandwich
This is only the second UK sports hall to be built using this system, the first being de ferrers Technology College in Burton on Trent, completed in June 2008. Each panel was constructed in a ‘sandwich’ fashion, with an inner 170mm skin of concrete separated from a 65mm outer skin by a 104mm insulation layer.
After panels had been lowered into
place, temporary support props were installed inside the building. Placing the building’s steel roof, which was bolted to the walls, made the structure rigid. Using precast panels reduced the quantity of scaffolding, cut the manual handling, and decreased the volume of waste generated, at the same time speeding up construction.

Extending a performance programme

requirement was for a minimum footprint and height, to fit within a walled garden, with the minimum visual impact to assuage planning concerns whilst conforming with LTA requirements for run-off and height.

Domes
A design incorporating four domes was devised by CopriSystems, with each dome covering one court. The domes are interconnected beneath support beams at a height of 6m, each supported by a single vertical support post between courts. Overall dimensions are 37m long, 67m wide with maximum height of 10m. The result gives an individual feel to each court whilst covering the four courts under one structure. Side curtains with a height of 2.5m extend the entire

perimeter of the structure and can be opened at any point to allow up to 75% to open. This gives the illusion of playing in the open air. In hot sunshine, due to airflow, it is cooler inside than out.
Payback
Membership of the school’s sports and tennis centre is also available to the local community for use during weekends, holidays and after school. Income from this club – along with coaching groups, Junior/Mini tennis programmes and the Junior Academy – bring in income to help repay the cost of the building.
The cover is in a single piece per court, has a white roof for maximum translucency, green sides and ends to provide a suitable backdrop for the balls. It is tensioned in all planes to maximise longevity. Lighting to LTA standards, has also been installed to enable day and night-time use, all year round. The structure has a galvanised steel lightweight lattice frame, rolled for rounded aesthetic effect and conforms with BS 6399 for snow and wind loadings. The indoor courts have a Proflex cushioned impervious acrylic playing surface, a medium/fast performance surface suitable for play at all levels up to a high standard. The resilient surface is suited to young players with developing bones and joints and extended training periods for aspiring players.
