University of Washington Parrington Hall Renovation

Seattle, Washington | Infrastructure & Public Works

The University of Washington completely reimagined the usability of the historic, 4-story Parrington Hall. Built in 1902, it is one of the oldest and most iconic buildings on the school’s Seattle campus. 

The project replaced outdated spaces with flexible classrooms that support active learning and created open staff and graduate student offices. It provided more collaboration areas across the building to increase utilization.

Hermanson teamed with Glumac to provide Progressive Design-Build for full mechanical design and construction upgrades, including a 4-pipe fan coil system with heat recovery DOAS consistent with UW’s commitment to 
sustainability and stewardship.   

Working under a tight budget and strict historic preservation guidelines, Hermanson was able to realize the following costs saving measures for the owner:

  • Reuse of the hydronic heating system and plumbing drain lines. 
  • Provide new chilled water branch lines to accommodate future construction projects in the area.
  • Provide on-site detailing to mitigate the uneven wall layout in a historic building to allow for the architect’s specification of no exposed piping.  
  • Reuse of vent stacks to avoid costly roof work.
