Construction Quality Assurance Observations (QAO)

What is the role of quality assurance in construction?

During the construction process, property owners often want to have an independent third party perform Quality Assurance Observations (QAO) and testing for the installation of components of the building enclosure. These observations are not necessarily required by the building department or local codes, but instead are designed to check that certain aspects of the building are constructed properly.

Generally, these construction observations focus on areas such as waterproofing, doors and windows, roofing, floor flatness, Exterior Insulation Finish Systems (EIFS) and other areas that impact the performance of the building and the occupant comfort. In addition, ECS can perform testing to verify proper sequencing and care are being observed.

What does ECS observe during QAO?

ECS performs third-party construction observations and testing for building enclosure components. These services help guide proper construction and long-term performance. Common areas include:

  • Waterproofing (below and above grade)
  • Doors and windows
  • Roofing
  • EIFS (Exterior Insulation Finish Systems)
  • Curtain walls, both unitized and stick built
  • Slab moisture mitigation
  • Relative humidity
  • Water spray testing of window and curtain wall assemblies
  • Infrared thermography for envelope leaks
  • Acoustic camera scanning for unintended air movement

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
  • Binder preparation with preliminary specs and cut sheets for client review

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

How does ECS approach construction quality assurance?

ECS focuses on proactive problem-solving and clear communication. Our QA process includes:

  • Reviewing plans and defining quality standards
  • Verifying materials and equipment
  • Tracking progress and nonconformance
  • Observing execution and environmental concerns
  • Final observations during handover

Expanded oversight approach

ECS’s approach to construction oversight reflects the philosophy that spot inspections should be standard, not optional. Many failures stem from improper or incomplete installation, which is why our team:

  • Participates in preconstruction and trade coordination meetings
  • Reviews products and materials on-site
  • Reviews mockups from start to finish
  • Collaborates in real time with installers, designers and manufacturers
  • Provides technical guidance so that corrections are made properly

We recognize that contractors are not designers, and our technical consultants play a key role in bridging that gap to protect project design outcomes.

What’s the difference between QA and QC?

  • Quality Assurance (QA): Sets standards and processes to drive quality
  • Quality Control (QC): Verifies that construction meets those standards

FAQ

Construction Quality Assurance Observations (QAO) focus on verifying that building components are installed properly during construction through field observations and testing. Building commissioning, by contrast, is a broader, performance-based process that begins in design and continues through occupancy to validate that systems meet defined performance goals.

Quality assurance observations are most effective when they begin early in construction, ideally during preconstruction and trade coordination. Early involvement allows ECS to review materials, evaluate mockups and provide input before installation issues become more difficult and costly to address.

When issues are identified, ECS documents nonconformances, communicates findings with the project team and provides technical guidance on corrective actions. The team collaborates with contractors, designers and manufacturers to support timely resolution and help keep the project aligned with design intent and performance goals.
