HVAC & Air Conditioning

Air conditioning and chilled water systems sized for UAE ambient loads, with complete ducting, insulation and balancing proved against specification before handover.

HVAC & Air Conditioning

Scope of Work

Our mechanical works cover plant rooms, chillers, pumps, AHUs, FAHUs and FCUs, the full duct distribution with insulation, and the controls that run them. Air-side balancing and water-side flow readings are recorded and witnessed, so the system is proved against the specification rather than simply switched on.

The mechanical team is led by a Projects Manager with 26 years of MEP experience, supported by a dedicated HVAC projects engineer and an MEP coordinator. HVAC formed part of every major package we have delivered, including the gas-plant camps at Shah Gas and the FERTIL-2 non-process buildings.

How We Work

From Tender to Defects Liability

The same five stages on every package, so you always know who holds the scope and what comes next.

01

Enquiry & Estimation

We review the drawings, specification and BOQ, raise the technical queries that matter, and price the package against a clear scope split.

02

Engineering & Approvals

Shop drawings, calculations, load schedules and material submittals prepared for consultant and authority approval before anything is ordered.

03

Procurement & Logistics

Approved brands only, ordered against the programme by our Procurement & Logistics Manager so long-lead items do not stop the sequence.

04

Installation & QA/QC

Directly employed foremen and technicians on site, with two QA/QC engineers and safety officers keeping inspection and test records current.

05

Commissioning & Handover

Systems tested, balanced and witnessed, then as-builts, O&M manuals, training and maintenance cover through the defects liability period.

Questions

HVAC & Air Conditioning — Common Questions

Do you design the HVAC system or only install it?

Both. Our scope on most packages is design, engineering, supply, installation, testing and commissioning. Where a consultant has produced the design we work from it and prepare the shop drawings, load calculations and duct layouts for approval.

Do you provide testing and balancing certificates?

Yes. Air and water balancing readings, commissioning sheets and the test and inspection records are compiled by our QA/QC engineers and issued with the O&M manuals at handover.

Can you maintain the plant after handover?

Yes — maintenance runs through the defects liability period and can continue under an annual contract afterwards. See maintenance & support.
