Witness Testing & Validation
Confirm that systems are installed correctly and performance is in line with design intent.
Trust us with independent verification of installed building systems
Witness testing is independent, third-party verification that installed building systems have been commissioned correctly and perform in line with the design specification. It is typically commissioned by the client, funder or insurer, separately from the contractor's own commissioning, to provide an objective record that the building is performing as designed before handover.
Reduce operational risk, support a smooth transition into occupation, and confirm systems are installed, tested and commissioned in line with design intent and specification.
IN2 carries out witness testing across a range of building types, with particular experience in NZEB and deep retrofit projects where SEAI and funder requirements demand documented performance verification as a condition of grant draw-down.
Allow us to help with:
- Witnessed commissioning of mechanical and electrical systems
- Independent system performance verification against design specification
- NZEB and deep retrofit commissioning validation
- Thermal and hydraulic system balancing verification
- BMS and controls functional testing
- Witness testing reports and sign-off documentation
- Commissioning support and handover documentation review
