KPFF takes Project of the Year for
Providence Park Eastside Expansion

for City of Portland (client/owner) and
Peregrine Sports LLC (Timbers and Thorns owner)

To accommodate the rapidly increasing Thorns and Timbers fan bases, the team owners wished to expand the east side of Providence Park Stadium. 

All new construction would need to co-exist with the original construction and numerous expansions over the stadium’s 100-year history. 

The field sits on the historic Tanner Creek Sewer and drainage had to be effective and invisible.

Phased construction was imperative to occur primarily in the Thorns and Timbers off-seasons. However, the Timbers played so well they extended their 2017 and 2018 seasons, pushing the start dates for construction by one month in 2017 and by two months in 2018. 

This left no room for float in the schedule. Could a unique renovation of this scale, on a publicly-owned facility with private interests, be designed and constructed during the variable phased construction windows and project budget? The expanded stadium, entrances, concessions, field, lighting, and team rooms all had to be completed and ready for the Timbers’ home opener. 

A project of this speed and magnitude required KPFF’s structural and civil engineers to immediately develop phased plans, structural sketches, and utility designs at a rapid pace. 

The result: On June 1, 2019, the Portland Timbers hosted Los Angeles FC in the renovated stadium for their season home opener! The stadium received its certificate of occupancy the day before. At kick-off time, Providence Park was filled with more fans, players and staff than ever before. 

The Providence Park eastside expansion was uniquely challenging, but it stands today as a proud testament to Portland’s professional soccer teams and creative collaboration between engineers, architects, and contractors.
