Commissioning: Testing, Adjusting, and Balancing (TAB)

Validation of design intent and operational capacity. Our TAB specialists measure and adjust air and water flow rates to confirm design criteria are achieved and system capacity is proven. We work in strict compliance with BSRIA, CIBSE, and ASHRAE standards, delivering documented evidence for handover, warranties, and ongoing operations.

Key benefits

Independent TAB closes the gap between installed plant and design performance—before critical loads are applied.

Thermal stability — Verifies chilled air or water reaches server intakes and maintains a stable environment under load.
Energy efficiency — Balancing matches delivery to real load so plant runs at the lowest safe settings, reducing energy and cost.
Equipment protection — TAB reports support warranty validation and confirm operation within manufacturer limits.
Design validation — Establishes baseline performance at handover and confirms the original design intent.

The commissioning workflow

Our workflow is structured to catch design and installation issues early, then prove performance under realistic conditions before final certification.

Initial design review — Feasibility input so cooling systems can be flushed, balanced, and commissioned as intended.
Feasibility study — Engineers review design documents against practical commissioning requirements.
Site inspection — Physical installation is checked against schematics; dampers and valves must be accessible.
Proportional balancing — Air and water flows are adjusted systematically to design setpoints across all plant.
Performance testing — Systems are tested under simulated load to verify thermal stability and pressure control.
Discrepancy reporting — Deviations from design intent are recorded and tracked to resolution.
Final certification — A comprehensive TAB report confirms data hall cooling capacity and efficiency.

Standards and reporting

Every project is delivered with traceable test data, clear remedial actions, and sign-off documentation suitable for clients, M&E contractors, and FM teams.
