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 Rimal is a modern district with large-scale residential and commercial projects, including villas, tower blocks, hotels and shopping complexes with complex central AC systems. This scale of development calls for robust electrical control panels, precise control wiring, and tight coordination between the cooling team, the main electrical crew and other trades on site. Modern buildings in Al Rimal also need their electrical systems to meet current standards and all electrical loads to be properly balanced and protected.
Al Rimal is in south Jeddah, a modern district of large residential and commercial projects with advanced infrastructure systems.
Most modern projects here rely on central AC systems with circulating pumps and complex electronic controls that need precise load balancing.
The AC setup in Al Rimal
- 1
Central electrical control panel
Large Al Rimal projects need a robust central control panel to manage all distribution pumps, fan circuits and the electronic equipment for the system.
- 2
Precise protected control wiring runs
Modern control systems need sensitive wires routed through insulated, ventilated conduits, kept separate from main power cables to avoid electromagnetic interference.
- 3
Dedicated electrical feed for the AC system
The control panel, pumps and fans in large projects need a dedicated electrical feed from the main transformer to ensure stability and protection from overload.
Before the visit
Before our visit in Al Rimal
- 1
Confirm the control panel location with the main contractor
We agree with the contractor on the control panel location before starting wiring, to ensure it is safe, maintainable and away from moisture.
- 2
Review electrical feed points with the main electrical team
Coordinate with the main electrical team on the dedicated AC feed points, protective breakers and required voltage before start day.
- 3
Map out wire routes and conduit paths with the contractor
We walk the site with the contractor to choose the best wire and conduit routes away from heat and moisture sources, avoiding clashes with other trades.

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 electro-mechanical work with the main contractor on a modern project?
We work in parallel with the contractor's team, timing our wiring and panel work to the overall building schedule, and join site meetings to keep every trade aligned.
Do large residential towers in Al Rimal need separate electrical feeds for the AC system?
Usually yes, modern tower blocks need a dedicated electrical feed for the AC transformer and controls to avoid overloading the main circuit and keep the system stable.
Are your control wiring runs protected against humidity and heat in these systems?
Yes, we use insulated conduits and ventilated cable trays per safety standards, and route the wiring away from intense heat sources and moisture points.
What is your role in balancing the pump and fan loads once the system runs?
We design the panels and wiring to distribute electrical load evenly, and we are present at the contractor's full-load start-up test to confirm each pump and fan runs in proper balance.
