Building Envelope Testing in Seattle

QED would like to congratulate Seattle Children’s Hospital and the entire project team behind the new Building Care: Diagnostic & Treatment Facility project on receiving the prestigious 2023 American Institute of Architects Healthcare Design Award. This recognition highlights the innovation, functionality, and patient-focused design incorporated into one of the Pacific Northwest’s most advanced healthcare expansion projects.

Located in Seattle, the expansion represents a major investment in healthcare infrastructure and patient care capabilities for the region. The project includes eight new operating suites, two catheterization labs, 20 flexible inpatient rooms, a specialized outpatient clinic focused on cancer and blood disorders, two pharmacies, and numerous laboratory spaces. These additions significantly expand Seattle Children’s ability to provide advanced medical care while supporting future growth and evolving healthcare needs.

QED was proud to support this project by performing diagnostic building enclosure and water penetration testing in Seatlle on portions of the curtain wall and glazing systems throughout construction. The photos from the project show technicians performing controlled water penetration testing using chamber systems and calibrated spray rack assemblies on large-scale curtain wall systems. These tests help evaluate the field performance of installed glazing assemblies and verify resistance to water intrusion under simulated weather conditions.

Modern healthcare facilities rely heavily on high-performance building envelope systems to maintain indoor environmental quality, energy efficiency, and occupant comfort. Large curtain wall and glazing assemblies provide natural daylighting and architectural openness while also creating complex waterproofing and air barrier challenges. Proper testing during construction helps ensure these systems are functioning as intended before the building becomes fully operational.

The diagnostic testing shown throughout the project included controlled water application and pressure chamber testing designed to evaluate installed field conditions. Unlike laboratory testing performed under factory-controlled settings, on-building testing evaluates the actual installed systems, including perimeter transitions, framing conditions, sealant interfaces, and installation quality. This process allows project teams to identify and correct deficiencies early in construction before occupancy.

Healthcare environments demand especially high performance standards because moisture intrusion or enclosure deficiencies can impact indoor air quality, sensitive equipment, and patient environments. Water penetration testing plays an important role in helping reduce long-term maintenance concerns while supporting building durability and operational reliability.

The completed facility showcases an impressive combination of architectural design, advanced medical functionality, and sustainable construction practices. The expansive glazing systems and modern façade design contribute to a welcoming environment for patients, visitors, and staff while helping maximize daylight and visual openness throughout the facility.

Projects receiving AIA Healthcare Design Awards are recognized not only for architectural excellence, but also for their ability to enhance healing environments and improve operational efficiency within healthcare settings. The Building Care: Diagnostic & Treatment Facility project stands as an example of how thoughtful design and quality construction can positively impact patient care and the broader community.

QED appreciates the opportunity to contribute to projects that prioritize performance, durability, and innovation in the built environment. Congratulations again to Seattle Children’s Hospital and the entire design and construction team on this well-deserved recognition and the successful completion of an outstanding healthcare facility.
