Construction activities continued steadily throughout March. Site preparation work progressed, including grading and underground servicing. Early foundation work began in designated areas, as well as some initial steel structural framing. Weather conditions have been challenging through the cold and snowy winter, with a wet spring, making for difficult conditions on the site.

• Installation of underground services in select zones;

• Structural steel framing and masonry block walls in Block A
