• Coordinated roofing, exterior wall, window and waterproofing systems with landscaping, mechanical, electrical, and plumbing designs

• Reviewed related submittals to compare with the design intent

• Observed in-progress and as-built construction to compare with the project requirements

• Evaluated variations in the as-built details and helped develop solutions

• Inspected below-grade waterproofing to verify compliance with manufacturer’s warranty requirements

• Conducted field testing to evaluate the performance of installed windows at 280 Beale Street
