Description

The main stage canopy is a landmark bandstand structure for sheltering outdoor musical performances at the annual Kongsberg Jazz Festival. The client was Kongsberg Jazzscenar AS (Norway). Canobbio SpA (Italy) has been contracted to manufacture the membrane and inflated beams. Engineering was done by Airlight Ltd, ing. A. Pedretti (Switzerland), while architectural concept and design was provided by Snøhetta AS, arch. Joshua Teas, Oslo, (Norway).

The construction consists of a membrane structure of tensioned polyester-PVC fabric over an inflated frame. The main stage can easily be mounted for temporary use in Kongsberg?s Kirketorget during the Festival, as well as for other events. The PVC membrane is particularly well suited to achieve dramatic lighting effects, and is acoustically neutral. The shape of the structure looks like a large saxophone, as the architect?s idea would have it.

The structure is 38 m long, 22 m wide and 19 m high. The fabric is supported by two steel arches and a steel ring. The steel ring is supported on the smaller arch by two steel profiles. The dimensions of the smaller arch are 7m x 14m. The bigger one, more like a tongue shape, is about 33m x 22m. Both ends of the arches are pinned on the ground. The steel ring diameter is about 12m.

Particular attention has been paid to the installation design. The client?s requirement was to be able to erect and dismantle the structure in a short time, because the Festival is annually held in the central plaza of the city. Due to the complexity of the structure, it has been pre-assembled in Italy, in order to verify the functionality of all the components. The entire installation is completed in about 5 working days.
