100% IndependentWe verify, never install
The problem we solve

You installed it to spec. Now prove it performs.

On critical projects, the consultant, authority, or owner wants performance shown independently: measured, documented, and traceable. When that proof is your own, it gets questioned, and your handover stalls. Independent TAB closes the argument for you.

01 / At handover

Your own numbers get questioned

Test and sign off the system you installed, and the consultant, authority, or owner can push back on whose data it is. An independent, NEBB-certified report takes that argument off the table. The proof isn't yours to defend, it just holds.

Risk: sign-off & retention held
02 / In operation

Imbalance surfaces after you've left site

Ductwork sealed, pumps running, yet zones still miss design airflow. Independent, measured balancing catches it before handover, not on a defects list that calls you back to close out.

Risk: callbacks at your cost
03 / Under audit

Readings that don't hold up

Cleanrooms, data centres, and healthcare spaces are audited against ISO and NEBB criteria. Readings without calibration traceability get thrown out, and the gap lands back on your scope. Traceable data holds the first time.

Risk: failed audit, back to you
Why Skud

Independent proof, built to pass audit.

Owners and consultants bring us in for evidence that holds up, before systems go live and long after.

01Authority

Common questions

The questions buyers ask before they call.

What makes Skud a specialist HVAC and cleanroom testing contractor?
Skud specialises exclusively in testing, verification and certification for critical environments. Our services include NEBB-certified Testing, Adjusting & Balancing, NEBB-certified Cleanroom Performance Testing, mechanical commissioning management, biosafety cabinet certification, data centre particle counting and specialised technical testing. We do not install the systems we test, allowing us to provide independent, traceable results for consultant approval, audit and handover.
Why appoint an independent NEBB-certified TAB contractor?
Testing performed by the installing contractor confirms that installation work has been completed. Independent TAB provides a separate verification that the air and water systems achieve the required design performance. Skud measures, adjusts and documents the system using calibrated instruments and NEBB procedural standards, giving contractors, consultants and owners a neutral set of results for acceptance and handover.
What is the difference between TAB and commissioning?
Commissioning verifies that building systems operate as intended across equipment, controls, sequences and interfaces. Testing, Adjusting & Balancing is the specialist discipline that measures and adjusts HVAC air and water systems to achieve their required design values. TAB supports the commissioning process, but they are separate scopes with different methods, responsibilities and deliverables.
When should TAB and cleanroom performance testing be carried out?
Skud should ideally be appointed before physical testing begins so that the scope, acceptance criteria, method statements and programme can be agreed. TAB normally starts after the relevant HVAC systems are installed, energised and operating under functional controls. Cleanroom performance testing is carried out when the room is ready in its specified as-built, at-rest or operational condition.
Does Skud provide specialist testing services across Malaysia and Southeast Asia?
Yes. Skud operates from Kuala Lumpur, Johor Bahru and Penang, supporting projects throughout Malaysia and mobilising regionally, including Indonesia and Thailand. Our teams serve data centres, semiconductor facilities, pharmaceutical plants, healthcare facilities, cleanrooms, industrial sites and commercial buildings.
