NATIONAL ARTS CENTRE REJUVENATION

The National Arts Centre in Ottawa was recently rejuvenated in advance of the 150 th anniversary of Canada’s Confederation. The scope of work included 6,000 square metres of new floor space, comprising three new connected wings, two new floors of lobby, and cultural programming, all of which is enclosed by a custom glass curtain wall. The key feature in the project is a striking coffered ceiling, providing a unique piece of structural artistry visible from the street—the result of a highly collaborative design by the architect, structural engineer, services engineer, contractor, and timber fabricator. The roof was formed of 28 hybrid wood-steel panels, spanning up to 19.5 metres, pre-fabricated off-site while the building strengthening and steelwork erection was carried out. Sprinklers, lighting, acoustic treatment, theatre attachment points, and temporary waterproofing were integrated into each panel in the wood fabricator’s shop. The entire 1200-square metre hybrid roof was lifted into place in under three weeks. Principal-In-Charge: Ian Boyle, P.Eng., Struct.Eng.
