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 Mawaddah is an advanced district with modern apartment blocks, hotels and mixed-use commercial projects, supported by modern infrastructure and reliable electrical networks. This pattern supports complex central AC systems and precise electrical runs, but requires deep knowledge of safety standards and tight coordination with other trades. Large mixed-use projects here need advanced electro-mechanical oversight from planning through to the first run.
Al Mawaddah sits in east Jeddah, a fast-growing sector mixing modern residential blocks, hotels and mixed-use commercial projects.
Large projects in Al Mawaddah typically need a separate electrical transformer and one main control panel distributing power across multiple AC and refrigeration branches.
The AC setup in Al Mawaddah
- 1
Separate electrical transformer with main panel
Large commercial and hotel projects in Al Mawaddah need a dedicated electrical transformer for the AC and refrigeration system, with a main control panel managing distribution.
- 2
Separate circuits for each system branch
Complex systems here need separate electrical circuits for each major pump or fan, allowing independent control and safe maintenance.
- 3
Protected runs in walls and floors
Long electrical runs in large projects are laid inside protective conduits within walls and floors, maintaining safety and future flexibility.
Before the visit
Before our visit in Al Mawaddah
- 1
Provide detailed electrical schematic for the project
Provide an updated copy of the electrical load diagram and proposed runs so we can assess requirements and compatibility with the central AC system.
- 2
Coordinate with contractor team on execution phases
Agree on a schedule for electro-mechanical phases so they complete before final finishes and do not clash with plumbing and interior finishing work.
- 3
Ensure access to the electrical transformer location
Confirm the transformer location in advance and ensure our team and the contractor can access it easily for installation and baseline readings.

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.
Do you handle complex electro-mechanical systems in hotels and commercial projects?
Yes, we specialise in large and complex systems. We handle the connection of pumps, fans and transformers, managing distribution across multiple synchronised AC and refrigeration units.
Many projects here need future system expansions; does your initial design allow for that?
Yes, we design the panels and electrical runs with spare capacity built in, allowing new AC or refrigeration units to be added later without redesigning the whole system.
Humidity in east Jeddah is high; how do you protect panels and connections?
We use electrical panels insulated against moisture, covered connections with protective materials, and place panels in well-protected indoor locations within the building.
How long does a complete electro-mechanical system take to deliver for a large residential block?
Duration depends on the project size, number of floors, synchronised systems and coordination with the main contractor; a site visit confirms the precise timeline.
