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 Nada is a modern residential district in east Jeddah with villas and apartment blocks set on spacious plots with varied architectural designs. Projects here need separate electrical runs for each residential or commercial unit, and tight coordination between the AC team, electricians and plumbers to meet the main contractor's schedule. Electro-mechanical works in such districts call for deep knowledge of architectural drawings and the ability to read the requirements of each building type correctly.
Al Nada sits in east Jeddah, a modern residential district with villas and spacious apartment blocks on separate plots.
Most residential projects here require a separate electrical panel for the AC system because of separate ownership and unit divisions.
The AC setup in Al Nada
- 1
Separate electrical panel per unit
The separate villas and apartment blocks here need their own electrical control panel for the AC system, with safe connections to the main power distribution board.
- 2
Central pump systems for larger projects
Larger residential and commercial projects in Al Nada may need a central pump system serving multiple units, with a main control panel and separate branches for each floor or section.
- 3
Smart fan connections and control products
Modern districts require advanced connections for distribution fans and smart control systems that work seamlessly with the building's other systems.

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 and other trades?
We work to the project schedule and liaise with the main contractor, electricians and plumbers before starting to ensure each phase flows smoothly without clashes.
The villas and flats here are separate, does each unit need its own electrical panel?
Usually yes, because of separate ownership and utilities, but this depends on the project design and electrical drawing, so we need a site visit to confirm.
Are there special requirements for electrical connections in modern districts like Al Nada?
Modern buildings here require smart control panels and precise connections with safety and monitoring systems, and work must align with current electrical standards and the project's architectural drawing.
How do you handle the wide spaces in villas and apartment blocks when running cables and pipes?
We use high-grade metallic conduits and insulated cables, and plan the runs carefully according to the architectural and electrical drawing to avoid conflicts with other systems.
