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 Wadiyah is undergoing steady expansion with modern residential projects and hotels, featuring large open-plan buildings that demand complex central HVAC and advanced electrical distribution. This calls for tight coordination between the main contractor and the electrical and mechanical trades from the start, with sensors, control panels and circuits wired to high precision to avoid faults when running. Alrabih's team works in parallel with the main project and monitors every connection and circuit.
Al Wadiyah lies in north Jeddah, defined by modern large-scale residential towers, villas and hotel projects spread across open plots.
Large-scale central HVAC systems in these projects require dedicated electrical panels and multi-storey control wiring, typically with high-capacity pumps and fans.
The AC setup in Al Wadiyah
- 1
Central electrical panels for central systems
Major projects in Al Wadiyah need dedicated panels fed from the main board, supplying control, protection and monitoring for the pumps, fans and control units.
- 2
Multi-storey control wiring runs
The tall towers here need coordinated control cables linking the pump room to the upper circuits, shielded against electromagnetic interference.
- 3
Dedicated power points for fans and pumps
Each main pump or fan gets its own power line from the panel, and we coordinate with the contractor to avoid overloading any circuit.
Before the visit
Before our visit in Al Wadiyah
- 1
Request the engineering and electrical drawings
Make sure the contractor has issued clear drawings showing the pipe runs, electrical routes and circuits before the first site visit.
- 2
Confirm the pump room and equipment room location
Make sure there is a designated, secure location for the pump room and panels, and it is easily accessible for later maintenance.
- 3
Coordinate with the main site about site facilities
Ensure adequate and safe power is available on site for the team's tools, and designate a checkpoint for coordination 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.
When does your team start the electro-mechanical works on a project?
We start after the engineering plan is set and the main contractor agrees, early enough before concrete pours to run the pipes and wiring through walls and slabs.
How do you coordinate with the building's main electrical contractor?
We map out the routes and shared points with the contractor before starting, and confirm that the connections do not clash and each unit gets its power from the correct panel.
Does Al Wadiyah's heat affect the design of the electrical panels?
Yes, the intense heat calls for better ventilation and insulation for the panels and cables, and we recommend running the runs away from sun-exposed walls.
If we expand the project later, can the panel handle the extra load?
We design panels with spare capacity based on the initial plan, but any major expansion needs further review, and we discuss future plans with you from the start.
