An ITP — Inspection and Test Plan — is a formal document that defines every inspection and test activity required during construction, installation, and commissioning of an HVAC system. It specifies who must be present, what standard must be met, and what evidence must be recorded. Without an approved ITP, no inspection can be officially witnessed and no work can be formally accepted by the client.

On Aramco, SABIC, FIDIC, and international projects, an ITP is not optional. It is a contractual requirement. If you start HVAC installation without an approved ITP — the client can reject your work even if it is technically perfect. The ITP is your quality roadmap from first fix to final commissioning.

Who Uses an ITP in HVAC Projects

Every party on an HVAC project interacts with the ITP. Here is how each party uses it:

  • HVAC SubcontractorPrepares and submits the ITP for client approval before work begins. Uses it to plan and schedule inspections throughout the project.
  • Main Contractor QCReviews and co-signs the ITP. Witnesses inspections marked as their responsibility. Signs the inspection record after each activity.
  • Consultant / EngineerApproves the ITP before work commences. Witnesses Hold Points and Witness Points. Issues approval or rejection of each inspection.
  • Third Party InspectorIndependently witnesses Hold Points and critical tests — pressure tests, leakage tests, commissioning — and signs the test records.

Understanding ITP Inspection Types — H, W, R, I

Every activity in an ITP is assigned an inspection type for each party. Understanding these codes is essential for reading and writing an ITP correctly.

CodeNameWhat It MeansCan Work Proceed Without It?
H HoldHold PointWork must STOP at this point. The inspection party must witness the activity. Work cannot proceed until the Hold Point is signed off.NO — Work stops completely
W WitnessWitness PointThe inspection party must be notified and given the opportunity to witness. If they do not attend after receiving notice — work may proceed.YES — After notification given
R ReviewReview PointThe inspection party reviews documents, test records, or submittals only. No physical presence on site required.YES — Document submission only
I InspectIn-house InspectionThe contractor performs their own inspection and records the result. No client or third party presence required.YES — Self-inspection

Critical Warning: If you proceed past a Hold Point without the required party signing off — the client has the right to reject all work completed after that point and instruct you to redo it at your own cost. Always get the Hold Point signed before proceeding.

What a Professional HVAC ITP Must Contain

A professional HVAC ITP covers every major system from ductwork to final commissioning. Here are the 6 sections our professional ITP format covers — with 35 inspection points total:

A
Ductwork — Fabrication & Installation (8 points)
Material verification, dimensions, joint and seam inspection, support spacing, duct leakage test low and medium pressure (H point — third party witness), fire dampers, flexible connections. References: SMACNA, NFPA 90A.
B
Air Handling Unit (AHU) — Installation & Commissioning (8 points)
Delivery inspection, structural mounting, filter check, fan rotation, supply and return airflow measurement, drain pan, vibration check. References: Manufacturer manual, project specification.
C
Fan Coil Unit (FCU) — Installation & Commissioning (6 points)
Delivery, mounting height, chilled water connections, condensate drain slope, airflow measurement at all speeds, thermostat and controls functional test.
D
Chilled Water Piping System (7 points)
Pipe material, support spacing, hydrostatic pressure test (H point — 1.5× design pressure — third party witness required), insulation thickness, vapour barrier, flow balancing, temperature verification. References: ASME B31.9, ASHRAE 90.1.
E
Insulation (3 points)
External duct wrap type and thickness, internal duct lining, equipment insulation with no cold bridging verification.
F
Commissioning & Final Testing (6 points)
TAB — Testing, Adjusting and Balancing (H point), indoor temperature and humidity, noise level measurement, BMS integration, fire mode smoke control operation, handover documentation. References: CIBSE, ASHRAE.

How to Use the ITP on Site — Step by Step

01
Submit ITP for Approval Before Work Starts
Submit the completed ITP to the client or consultant before any HVAC installation begins. The ITP must be approved and signed before the first inspection can take place. Work started before ITP approval may be rejected.
02
Notify All Parties Before Each Inspection
Give minimum 24 to 48 hours notice before each inspection — especially for Witness and Hold Points. Send a formal inspection notification with date, time, location, and ITP reference number. Keep proof of notification.
03
Complete Each Inspection — Record the Result
At each inspection point — record the result against the acceptance criteria. Mark PASS or FAIL. Attach supporting documents — test records, calibration certificates, photographs. All parties present must sign the inspection record.
04
Do Not Proceed Past Hold Points Without Sign-off
At every Hold Point — stop work. Conduct the inspection. Get signatures from all required parties. Only then continue. The duct leakage test, chilled water pressure test, and TAB commissioning are all Hold Points requiring third party witness.
05
Compile Complete ITP Record for Handover
At project handover — submit the complete signed ITP record with all inspection records, test certificates, and photographs. This forms part of the O&M documentation and is required for the defects liability period.

Important: Keep the ITP as a living document throughout the project. Update it if the scope changes. Any new equipment or system added after ITP approval must be submitted as a revised ITP revision before inspection.
