Canam's post about the architectural canopies at street level:

The canopy structure, made from jumbo HSS (or jumbo “Hollow Structural Sections”), was specially designed to support the organic curves of the design. To ensure both structural integrity and aesthetics, each component required extremely precise rolling and fabrication. Then, after being fabricated separately, each section was carefully assembled to ensure that the whole piece was perfectly aligned and in harmony with the other architectural elements of the project. This technical achievement was a challenge not only in terms of design, but also of installation, since we had to use multiple cranes to precisely position each large component.
