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 Zumurrud is a modern-growth area with spacious villas, residential towers and hotels, each requiring a dedicated electrical panel and complex control wiring between central AC units, pumps and fans. Coordinating the electro-mechanical team with the main contractor and other trades is essential because these projects run tight schedules. The open spaces between buildings give better scope for running power and pipework, unlike older districts.
Al Zumurrud is in North Jeddah, a modern development area mixing villas, towers and hotels.
Most projects here run separate electrical panels per plot or tower, with heavy-duty supply for the central pumps and fans.
The AC setup in Al Zumurrud
- 1
Dedicated electrical panel per project
Large Al Zumurrud projects need a separate panel to precise engineering specs, with metering and protection to Saudi standards.
- 2
Complex control wiring between units
Central systems in hotels and towers need dedicated control wiring between outdoor, indoor and panel units, shielded against electromagnetic interference.
- 3
Electrically isolated pump units
Central pumps and fans need separate power supply and safe earthing, especially where heat exchangers are used in large towers.
Before the visit
Before our visit in Al Zumurrud
- 1
Have electrical drawings ready
Site conditions may differ from initial drawings, so have an updated version of cable routes and critical points ready before we visit.
- 2
Agree on the electrical panel location with the contractor
The main panel must sit in a safe, accessible location near the main power inlet point from the street.
- 3
Confirm earthing and surge protection availability
Check that a safe main earthing point exists on site, and prepare the installation location away from moisture and water sources.

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 works with the main contractor?
We work alongside the main contractor from the design phase, marking out power routes and critical connection points before execution begins.
Large projects here run tight schedules; what time frame do you need?
The schedule depends on project size, unit count and footprint. We meet the contractor on site to agree a coordinated timeline before we start.
Do hotel project electrical panels need heavy-duty supply?
Yes, hotels and large residential towers need three-phase heavy-duty supply with overload protection; we test the entire panel before handover.
Outdoor units and pumps sit far from the panel; how do you run the power?
We run heavy-gauge insulated cable underground or along facades depending on site layout, using metal conduit to protect against weather and damage.
