SGH joined the project during the design phase and peer reviewed design of below‑grade waterproofing, custom high-performing unitized curtain walls, vegetative and low-slope roofing, and canopies. As the BECx provider, we helped the project team establish performance criteria for the building enclosure and develop quality assurance procedures for verifying and documenting that it met the requirements. Highlights of our work include:

• Developing the BECx plan and draft specification, and outlining testing requirements, project team roles and responsibilities, and procedures for documenting and resolving construction-related issues
• Reviewing the enclosure design, including complex curtain wall interfaces; recommending ways to improve performance, energy efficiency, and constructability; and confirming the documents meet the owner’s project requirements
• Visiting the curtain wall manufacturing facility to observe fabrication processes and quality control procedures, and guide mockup performance testing efforts
• Reviewing contractor submittals and visiting the site to observe ongoing construction for comparison with the design intent—including requirements for the curtain wall, sensitive below-grade spaces, and accessible garden and patio roofs
• Helping address field conditions during the construction phase and observing enclosure testing for comparison with performance expectations
• Preparing a BECx report summarizing completed work, construction deviations, site observations, and executed performance testing
• Performing a follow-up review of the building enclosure ten months after occupancy
