CLT also offered the project team some headaches. Purchasing and procurement of the CLT panels occurred during the unprecedented price escalation and shipping delays linked to the COVID-19 pandemic. The project team partnered with a logistics company capable of transporting material from multiple ports, giving the manufacturer more flexibility in finding vessels from Europe to the U.S. Those, and other materials, had to be carefully coordinated for just-in-time delivery thanks to the zero lot line downtown site.

To minimize the potential of damage from handling panels, the team conducted extensive front-end planning with careful attention to shipping and handling as well as rigorous onsite management.

Execution of the innovative building type utilized BIM technology, and in the field, the project team utilized virtual reality technology to ensure systems were installed in accordance with the model. The model was created within two months after subcontracts were awarded, detailing all penetration locations, core accessibility and openings and connection details. CLT erection requires tight tolerances for fit and finish, and the project team says its most difficult challenge was protecting the panels after they were installed.

Multilayered waterproofing during erection maintained quality CLT characteristics, and dedicated crews were tasked with following extensive procedures to mitigate water intrusion.
