NEXUS was contracted by BCRA to provide comprehensive building envelope consulting, design and testing for a new five-story multifamily apartment project over two stories of concrete parking structure on the Thea Foss Waterway in Tacoma, Washington on the Thea Foss Waterway.
During the design phases, NEXUS provided guidance on building envelope materials and designed waterproofing, window and air barrier details. Additionally, NEXUS performed energy modeling and prepared the submittals required for Washington State Energy Code compliance.
Once construction commenced, NEXUS coordinated closely with Sierra Construction to facilitate air barrier and waterproofing installation quality control inspections during key installation periods. NEXUS led the pre-installation meeting and performed mock-up water penetration testing to evaluate the window integrity and installation. Testing resulted in changing the window manufacturer prior to construction due to inferior performance saving the owner significant time and money as well as improving the overall quality of the building.
During installation, NEXUS performed in-situ water penetration window tests as well as air barrier installation inspections and final air barrier testing of the completed building envelope. This project was unique in that the owner decided to phase occupancy during construction resulting in a two-phase air barrier test. Infrared thermography was used to identify air leakage during the final air barrier testing and all test results/findings were formally documented in a written report.
