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 Ma'rifah is an upscale residential district with high-rise blocks, small shopping centres and luxury villas, set within well-planned outdoor spaces. Projects here are modern and designed to high standards, needing refined electro-mechanical systems with advanced control panels and precise connections between multiple units. Coordination with the main contractor and other trades is critical to hand over a balanced and efficient system.
Al Ma'rifah lies in north Jeddah, an upscale residential district with high-rise blocks, commercial facilities and modern villas with coordinated design.
Most projects here require an advanced electro-mechanical system with smart control panels and complex connections because of the scale of the blocks and villas.
The AC setup in Al Ma'rifah
- 1
Advanced central system for tall blocks
Blocks in Al Ma'rifah typically use powerful central cooling units with electronically controlled air distribution per floor, requiring a sophisticated electro-mechanical system.
- 2
Villas with multi-zone split systems
Luxury villas here typically choose multiple indoor split units on a single outdoor heat pump for separate control in each home zone.
- 3
Smart control panels and monitoring connections
Modern projects require programmable control panels and monitoring connections to track performance and alert the owner to any fault.

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.
High-rise apartment blocks need complex control systems, how do you handle them?
We design custom control panels to manage multiple units in balance and safety, and test each circuit before handover to ensure consistent performance across all floors.
The villa in Al Ma'rifah is large, how do you choose where units and connections go?
We follow the original drawings and choose locations to balance performance and architectural design, and confirm every position with the owner and engineer.
Summers are very hot and humidity is high, does this affect the wiring and units?
Yes, heat and humidity increase the load, so we use thicker-gauge wire and protect outdoor units with covers or screens from direct rays.
The system needs to run at high efficiency, what needs to be in place before startup?
Ensure all pipes and ducts are flushed clean of debris, electrical loads are balanced across circuits, and pump fluid levels are correct before first start-up.
