KPFF provided civil and structural engineering, as well as surveying and 3-D scanning services, for the Providence Park Stadium Expansion. The stadium is home to Portland Timbers FC (MLS) and Portland Thorns FC (NWSL). The project included the addition of 4,000 seats on three levels, located above and behind the existing east side seating, raising the stadium capacity to approximately 25,000. In order to fit the new seating into the existing footprint, the tiers were built onto a vertical wall, effectively creating a formidable wall of soccer fans. A 150' cantilever canopy added over the entire east side of the stadium is anchored by steel that extends down the back side to the sidewalk below, creating a visual hallmark of the expansion. The top level of the addition includes observation decks and an open-air concourse with views of the city. Permitting included provisions for extending the cantilever over the public right-of-way and creating a welcoming street-level concourse. Stormwater management was provided underneath the playing surface and was designed to protect the historic Tanner Creek Sewer that runs beneath the stadium. Additional elements of the $85M expansion include new LED video boards, upgraded field turf, remodeled locker rooms for the Portland Timbers and Portland Thorns, and new and updated concessions stands. KPFF provided services from design through construction of the project.
