In February 2012, Buffalo, New York Mayor Byron Brown challenged the local development community to submit ideas to revitalize the Webster Block, an underutilized city block adjacent to First Niagara Center, former home of the NHL's Buffalo Sabres. The team of Mortenson, Populous, and CAA ICON submitted the winning plan for a multi-use facility designed to bring the Buffalo Entertainment District to life.

Together the team worked diligently to develop the design, confirm the project budget, and establish the overall construction schedule before breaking ground in April 2013. As Construction Manager, Mortenson led the overall construction efforts including community outreach, scheduling, site logistics, and project execution.

The official practice facility of the Sabres, Harborcenter offers patrons a two-rink community hockey center set atop a 750-car parking ramp, destination restaurant, retail shops, and Marriott Hotel. The ice rinks, parking structure, and restaurant celebrated with a grand opening in the fall of 2014, with the hotel opening the following summer.
