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 Asaliyah is a relatively modern residential district with multi-storey buildings and spacious villas with adequate outdoor areas. This building character allows proper scaffold setup, overhead tanks and pumps, meaning the electro-mechanical scope includes complex central control panels and long wire runs across multiple floors. Coordination with the main contractor and other trades becomes critical because the project advances in successive phases.
Al Asaliyah lies in south Jeddah, marked by a mix of modern apartment buildings and independent villas in relatively organised neighbourhoods.
Most projects here involve central distribution panels and control lines spanning multiple floors, with overhead tanks and feed pumps.
The AC setup in Al Asaliyah
- 1
Central distribution panel serving multiple floors
Al Asaliyah villas and apartment blocks need one or two main panels distributing power and control across separate floors, with reliable overload protection.
- 2
Control lines routed through protective conduit
Long distances between outdoor units and the panel require sturdy metal or plastic conduit to protect wires from damage and moisture.
- 3
Pumps and tanks with safe control
Overhead tanks and pumps require quick isolator switches and reliable pressure controllers for stable and safe operation.
Before the visit
Before our visit in Al Asaliyah
- 1
Obtain a copy of electrical and mechanical plans
Send us the drawings before starting so we can review the planned panels, pipes and wires and suggest any early modifications.
- 2
Agree a schedule with the construction team
Fix with us and the contractor when the electro-mechanical works will start, so other activities are not delayed and work areas are safe.
- 3
Ensure the team can reach roofs and upper corners
Villas and apartment blocks may need temporary scaffolding or safe access ladders to upper units, so agree this in advance.

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 across different project phases?
We review the plans in advance and prepare a schedule for electro-mechanical works that aligns with the contractor's timeline. We attend regular coordination meetings to ensure control wiring and pumps are ready before other trades arrive.
The villas here are spacious; how do you run long wiring from a single control panel?
We plan wire routes in advance through protective conduit and use adequate gauges to prevent voltage drop over long runs. We test every line before final units are installed.
How do you handle the overhead tanks and pumps on upper floors?
We fit safe control switches and isolators between the tank, pump and main electrical circuit. We test water flow and pressure before final handover to ensure safe operation.
Do you run both pipes and electrical wires in the same wall cavities?
No, we keep electrical wiring at least 30 cm away from water pipes as a safety minimum and per local code. This prevents a potential leak from damaging the wires or causing shock.
