LOCATION: Portland, Oregon
The Portland Building was originally constructed as a simple painted concrete box, detailed with a rudimentary mortar-set tile system and a curtainwall glazing system. The existing cast concrete exterior needed to be reconstructed and detailed in such a way that it would be durable and weather-tight while maintaining the building’s historic features. The team designed a pressure-equalized rainscreen overclad to the exterior enclosure. The system provides insulation, protection and moisture management for the building while preserving its iconic appearance.
PROJECT SIZE: 15 story, 360,000 sq ft
“I was really impressed with DLR Group’s thoughtful renovation of the Portland Building. After suffering from its original low budget and multiple patches and repairs, it’s been given a new life. Best of all, the city’s employees will soon have a much-improved workplace. Kudos to DLR Group, the contractor Howard S. Wright, and the City of Portland for pulling this off!”
