Installation commissioning: ensuring everything works as designed

We carry out the commissioning of HVAC, DHW, electricity, telecommunications and Fire safety installations, ensuring that each system and the building as a whole function correctly before occupancy.

Commissioning
The 5 phases

Structured commissioning methodology

Our process follows international best practices (ASHRAE Guideline 0) in five sequential phases.

Phase 1 — Planning

We prepare the commissioning plan before the start of the work: objectives, systems to be commissioned, test procedures and acceptance criteria.

Phase 2 — Installation verification

We check that the equipment is correctly installed: mechanical assembly, electrical connections, labeling and accessibility for maintenance.

Phase 3 — Individual functional tests

We test each equipment and system individually: flow rates, temperatures, pressures, electrical protections, cabling certification, detection tests.

Phase 4 — Integrated tests

We test joint operation: SADI + smoke control, emergency switching, integrated BMS, failure scenarios and automatic sequences.

Phase 5 — Training and delivery

Training of the operation and maintenance team, delivery of compiled manuals, commissioning report and preventive maintenance plan.

Discipline-by-discipline testing

Every system tested rigorously

Each discipline MEP has its own procedures and acceptance criteria defined in the planning phase.

Benefits

What you gain from commissioning

🏢

Functional building from day one

Occupants will find comfortable air conditioning, adequate lighting, operational networks and active safety.

💰

Reduced correction costs

Problems identified during commissioning cost a fraction of what they would cost after occupancy.

👥

Prepared team

Training the maintenance team ensures that systems are operated correctly, extending their useful life.

📄

Reference documentation

The commissioning report is the baseline for all future maintenance and operation of the building.

Ensure that your building is delivered functioning, not just looking finished.
