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
Harat Al Sham is densely packed with old buildings, ageing electrical systems, cramped wire paths and limited space for new equipment. When upgrading an AC or refrigeration system, reliable electrical connections must be replaced and wires rerouted safely through thin old walls. Electro-mechanical work here demands skill adapting to existing space and structure, and coordination with shop and flat owners to avoid disrupting daily activity.
Harat Al Sham is in Jeddah's historic downtown, a tightly packed area of old buildings with outdated electrical systems and tight space for service upgrades.
Most old buildings here have thin copper wiring and narrow conduits, requiring wholesale replacement when installing new high-power AC or refrigeration equipment.
The AC setup in Harat Al Sham
- 1
Full old wiring and conduit replacement
Old buildings require complete removal of degraded wiring and conduits, replaced with new wire and conduits meeting high standards.
- 2
Single main distribution panel on the exterior wall
Limited interior space in old buildings means the main panel mounts on the exterior wall with weatherproof protection.
- 3
New connections with moisture protection
All new electrical connections installed with moisture and mould-resistant covering to maintain system integrity long-term.

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.
Can you renew electrical wiring in very old buildings?
Yes, we remove weak old wiring and replace it with new copper wire meeting international standards, installing new protective conduits where feasible.
Space in our alley is very tight, how do you fit the new distribution panel?
We survey panel placement beforehand with the building owner, usually mounting it on an exterior wall or in a tight space after clearing old obstructions.
Does moisture in old buildings affect wiring, is that a hazard?
Yes, high moisture and mould accelerate wire corrosion, so we use moisture-resistant metal conduits and high-grade insulated wiring.
Can the new system be installed without stopping the shop?
We coordinate with the shop owner to install the system in phases, keeping power to other systems running throughout.
