Construction Quality Assurance Observations (QAO)

What does ECS observe during QAO?

ECS performs third-party observations and testing for building enclosure components. These services are generally not required by code but help guide proper construction and long-term performance. Common areas include:

• Waterproofing (below and above grade)
• Doors and windows
• Roofing
• Floor flatness
• EIFS (Exterior Insulation Finish Systems)
• Curtain walls
• Slab moisture
• Relative humidity
• Spray testing of window assemblies
• Infrared thermography for envelope leaks

What door hardware services does ECS provide?

ECS now offers architectural door hardware consulting services that support design integrity, facility standards and long-term performance. These services include:

• Hardware submittal review and coordination
• Keying and master-keying strategy development
• Compatibility analysis with facility standards and materials
• Coordination of hardware sets and openings lists
• RFI response and site visit support
• Non-proprietary specifications to avoid manufacturer bias

These services help reduce field changes, avoid costly proprietary systems and make sure hardware aligns with the project’s design intent and operational needs.
