The Leaf at Canada’s Diversity Gardens project consisted of a 33-meter-high center Diagrid system. The diagrid was fabricated in 33 large welded frames assemblies from 12” diameter steel HSS/pipes welded to Steel Node Castings supplied by Cast Connex. These frames were assembled in place and field welding together. The diagrid was designed to transfer the high loads from the cable net and EFT roof system down to the foundations. Supreme Steel worked closely with the design team to determine the most efficient details for the fabrication and erection of this complex structure while still maintaining the Architects design intent. Due to the structure’s geometry, the installation, fabrication and connection design posed many issues which the team at Supreme Steel successfully brought to completion. At project completion Supreme will have fabrication and installed the 490 tonne Diagrid core, the 412 tonne biome and the 432 tonne support building.
