Upon completion, the Globe and Mail Centre will consist of a 19-storey tower and a seven-storey podium. The building will include a theatre venue, conference centre, restaurant, video recording space, meeting rooms, offices and open workspaces.
Design elements like the “torqued” wall along the west elevation of the tower combined with various slopes and angles accenting the curtain wall system and cladding will make the Centre stand out from its neighbours.
Envelope design decisions like using triple-glazed insulating glass units within a thermally broken curtain wall system will help ensure the building meets energy efficiency goals. Ground floor glazing will consist of a high spanning structural glass wall system.
The building will feature a large column-free ground-floor lobby and theatre venue. We will use 1,500 deep plate girder sections to furnish support traditionally provided by columns.
Challenge: Glazing and trusses must coexist by the southeast corner column at the podium’s main entrance without being visible across the windows. Also, given the custom layout of the “torqued” and “creased” elevations, the curtain wall design could have been over-designed and led to higher-than-necessary tender prices.
Solution: Veirendeel trusses fit the design intent better than conventional trusses while ensuring connections between columns and beams are stiff enough to limit deflections and strong enough to support imposed loads. Entuitive conveyed design options and strategies to pre-qualified curtain wall manufacturers to help them understand performance requirements. This approach let to competitive tenders that were within the owner’s budget.
