Art Gallery of Ontario – Transformation advanced connection design and CNC technology

18h / mardi 25 octobre 2011PAVILLON MACDONALD-HARRINGTON SALLE G-10, Université McGill

In 2008, the Art Gallery of Ontario re-opened after a major expansion and renovation by architect Frank Gehry. A significant part of the new construction is the glass curtain wall supported by glued-laminated timber (glulam).

A five-storey tower and an extensive 3,600 sq. ft. central skylight feature rectilinear glulam mullion grids, while the feature Galleria running for 500 feet along Dundas Street is entirely curvilinear.

Creating this complex geometry where no two pieces are alike, with thousands of unique connections, in wood members with slender cross sections and significant forces was made possible by the use of CNC machines and the 3D CAD systems (BIM) that feed them

The challenging fabrication procedure, erection sequence and hidden connection design were all possible thanks to the tremendous advances in these technologies since 2000.

David Moses

David Moses, Ph.D., P.Eng., P.E., LEED®AP is Principal of Moses Structural Engineers Inc., in Toronto. His work as a structural engineer includes the design of heavy timber in innovative and award-winning commercial, institutional and residential projects in North America and parts of Asia. When he was with Equilibrium Consulting, he led the detailed connection design for the Art Gallery of Ontario (AGO).

David is a regularly-invited lecturer and has broadly published articles on his timber research, particularly on the use of 3D solid models for long-span structures.

David sits on several committees including the CSA Steering Committee for Forest Products, CSA A369 and CSA A370 as well as several WoodWorks! Ontario committees.

David received the Forest Products Society’s “2011 Wood Engineering Award” and a 2009 WoodWorks! Ontario award.
