• Performed below-grade waterproofing warranty inspections
• Witnessed field performance testing of cladding and fenestrations, and flood testing of amenity roofing and terrace waterproofing systems
• Provided construction-phase services, including reviewing contractor submittals, providing isometric sketches and cladding models to help the installers, observing ongoing construction, and helping address field conditions
