He also notes that the system allows crews Bockstael Construction to erect its central core.to complete one floor every six working days, thereby The first-in-Canada system is comprised of steel beams,eliminating the crane time required for concrete forming modular steel formwork panels, hydraulic jacks, threeand placing.

As such, Marwest has spent significant time and resources ensuring its crews and partners are working to the highest standards of health and safety, and that infection control measures are in place and enforced throughout the 300 Main site.There were two challenges for us going into the pandemic: keeping everyone safe and keeping everyone productive, says Martens.
