When these works are needed
- 1
A new central HVAC project
In commercial, government and industrial buildings, fitting units and ducts is not enough. You need electrical runs sized for the loads, a control panel that starts and stops equipment in the right order, and pumps and pipework designed for the building.
- 2
Extending an existing HVAC system
Adding units or new control zones means extra load on the panel and new control cabling. We review the available capacity on site and define what the extension needs before any work starts.
- 3
Electrical faults stopping the equipment
A unit that will not start despite being in good order, a pump that burns out repeatedly, breakers tripping for no clear reason: these are usually a wiring or panel problem, not a fault in the equipment, and need diagnosis from a technician who understands both sides.
Who it's for
Building a new commercial or government project
We review drawings with the main contractor and take on power panels, electrical runs, control automation, pumps and ventilation from start to handover.
Ask on WhatsAppYour HVAC equipment keeps breaking down
We diagnose the electrical and mechanical side of the system and identify whether the fault is in the panel, the wiring or the control circuits before any work begins.

How we work
How we work
- 1
Review project drawings
We go through the electrical and mechanical drawings with the designer or main contractor and define the power requirements and cable routes before any materials are prepared.
- 2
Site coordination
Electro-mechanical works cross paths with civil works and finishes. We follow the site programme and agree the sequence with other contractors so no trade is held up by a clash.
- 3
Run cables and fit equipment
We pull cables, mount panels, pumps and ventilation fans, then wire the control and automation circuits according to the approved site drawings.
- 4
Coordinated testing and start-up
We test each circuit individually then run the full system together with the AC equipment, checking that automation starts and stops everything in the right order before handover.
Planned coordination or clashes that delay the project?
| Alrabih | The usual way | |
|---|---|---|
| Electrical panel | Sized for the actual load | Rough sizing causes problems later |
| Control wiring | Documented to drawings | Run without documentation |
| Site coordination | Followed with every trade | Each trade works in isolation |
| Start-up test | Full test before handover | Faults found after handover |
| Change documentation | Recorded at handover | Verbal changes, no record |

What sets this district apart
Al Hafnah has multi-storey residential, commercial and some government facilities, with relatively tall buildings needing complex central AC systems spanning several floors. Main challenges are distributing electrical loads evenly across the building and coordinating vertical and horizontal pipe and duct routes. Electro-mechanical works need careful planning because each floor may need different balancing to run evenly.
Al Hafnah lies in east Jeddah, an area of multi-storey residential and commercial projects alongside government facilities.
Most buildings here use complex central AC systems with vertical wiring running several storeys, needing electrical panels distributed across the building.
The AC setup in Al Hafnah
- 1
Complex central systems with vertical and horizontal wiring
Tall buildings in Al Hafnah need electrical wiring spanning several floors with even load distribution.
- 2
Electrical panels distributed across floors
Multi-storey buildings here benefit from sub-panels across several floors instead of one central panel to reduce power loss.
- 3
Balancing and calibration system for fans and pumps
Each floor may need different pressure and flow calibration, and we fine-tune each section to ensure even cold air distribution across all units.

FAQ
Questions about Electro-mechanical works
Can you handle the electro-mechanical works when there is already another civil contractor on site?
Yes. We work as a specialist subcontractor alongside the main contractor, coordinating cable routes, pipework and equipment positions with the other trades on site. Before work begins, we identify where our scope crosses the civil and structural work and agree on the sequence of installation to avoid clashes.
What is the difference between the power circuit and the control circuit in an HVAC project?
The power circuit carries current from the panel to the compressor, motor or fan; cable size is set by the load. The control circuit carries low-voltage signals between sensors, thermostats and the controller; it issues run, stop and modulation commands. A fault in either circuit disables the whole system, so each is routed and terminated independently.
Does your work include connecting the automation system to a building management network?
Yes, when a building management network is already present on site. We connect the HVAC control units to the designated interface points and test signal exchange between the two sides. Protocol details and configuration are agreed with the team responsible for the building management network before installation begins.
How do you handle a clash between cable routes and ducts or pipework?
We identify clashes at the planning stage before installation starts, then consult the relevant trades to agree on an alternative route. If a site resolution is not possible, the clash is escalated to the project supervisor for a decision. Priority is always given to keeping the correct bending radius for cables and the required fall on condensate drain pipes, as compromising either affects system performance.
How do you handle a clash between cable routes and ducts or pipework?
Clashes between cable routes, ducts and pipework are common on medium and large projects. We identify them during the drawing review stage, before any trenching or pulling begins, and agree an alternative route with the trades involved. Changing a route on paper is far simpler than reworking it on site.
How do you handle vertical wiring in tall buildings?
We coordinate with the engineer on wiring routes through columns and structural voids, use secure conduit and clear paths before installation to ensure smooth cable pulling.
Load balancing across different floors needs special calibration, how do you do it?
We divide electrical loads across sub-panels distributed through the building and test each floor before final commissioning to confirm balanced pressure and flow.
Al Hafnah is very hot and dry, does this affect the wiring and pumps?
Yes, heat and dryness can cause contraction and cracking in some insulation, so we select heat-resistant wiring and install expansion joints in pipes to handle thermal swings.
Commercial buildings need zero-downtime operation during work hours, how do you ensure this?
We install parallel systems so we can commission new units while old ones run, then switch load without interruption. Advance planning with the contractor is essential.
