SOLUTION

SDSU required that the ADRDL enclosure be designed and constructed to be air tight, water tight, and thermally efficient. Commissioned enclosure systems included air and water barriers, thermal insulation, vapor retarders, joint sealants, fenestration, roofing, below-grade waterproofing and cladding assemblies. WJE performed design phase reviews of the project drawings and specifications and provided review comments identifying areas of performance concerns to the architect and owner for consideration. In addition, WJE developed a BECx plan and a BECx specification and testing regimen intended to verify and document performance of the components of the building enclosure assembly. Submittal reviews were also performed concurrent with the design team.  

During construction, WJE responsibilities included participation in preinstallation meetings for various enclosure systems, and implementation of the BECx plan by making regular construction observation site visits. During the mockup, WJE identified concerns with the attachment of the integrated sheathing, which was intended to be an all-in-one integrated moisture, air, and thermal layer. Air infiltration and water penetration testing confirmed that the installation method allowed for air and water leakage, which was corrected before widespread installation.  

WJE also witnessed air infiltration and water penetration testing of the curtain wall and storefront window systems to verify performance.
