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 |

From Al Shiraa and Al Yaqout in the north to Al Thaghr and Al Quraiyat in the south, with our base in Al Aziziyah.
What sets this district apart
Al Aziziyah holds a mix of modern villas, apartment blocks and large commercial facilities, each needing its own electro-mechanical system tailored to its demands. Major residential projects, hotels and hospitals need close coordination between the main contractor and the electro-mechanical team to time installation and testing. In Al Aziziyah, projects often clash with existing pipes and other runs, so careful planning before work starts is essential.
Al Aziziyah lies in central Jeddah, a district blending mid-rise residential blocks with major commercial and hotel projects.
Large projects here typically need distributed main power panels and multiple control points to feed different AC and refrigeration systems.
The AC setup in Al Aziziyah
- 1
Distributed main power panels
Large projects in Al Aziziyah typically need more than one main panel to distribute power across the different AC and refrigeration systems in the building's wings.
- 2
Multi-point control systems
Hotels, hospitals and large residential blocks need distributed control points for different zones, with centralised monitoring from a control room.
- 3
Power and control cable runs
Cable runs need careful planning before the concrete pour on floors and walls, especially in large projects with multiple systems.

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 coordinate with the main contractor on site?
We work to an agreed schedule with the contractor before starting, and track the electro-mechanical sequence alongside other trades through to handover.
Do projects in Al Aziziyah need custom-built power panels?
Yes, the project size and the different systems within it determine the power panel and control specs needed, and we coordinate the design with the site engineer first.
Existing pipes and runs may clash with our installation, how do you handle that?
We survey the project site beforehand to map existing pipe and cable routes, and adjust the layout to avoid clashes or reroute if needed.
When in the project sequence do the electro-mechanical works begin?
Installation usually starts after the concrete frame and initial runs are complete, so everything aligns before the finishing phase.
