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 Rayyan is a zone of residential and hospitality growth with multi-storey projects, hotels and modern residential compounds, typically needing advanced central cooling systems and complex electrical connections due to multiple units and floors. The electro-mechanical work here combines careful planning and contractor coordination; each floor may need a branch from the central system, and each branch requires its own safe electrical connection.
Al Rayyan lies east of Jeddah, a zone of multi-storey residential and hospitality projects with modern wide-span buildings.
Most projects here use central cooling systems distributed across multiple floors, needing smart control panels and electrical runs through the building's vertical ducts.
The AC setup in Al Rayyan
- 1
Multi-floor central cooling systems
Residential and hospitality projects in Al Rayyan rely on a single central cooling system distributing chilled air to each floor through separate branches.
- 2
Advanced smart control panels
Each multi-floor building in Al Rayyan needs a smart control panel managing temperature and humidity on each floor independently and efficiently.
- 3
Electrical runs through vertical ducts
Electrical wiring and connections run through the building's vertical ducts, allowing uniform and safe power distribution to each unit on every floor.
Before the visit
Before our visit in Al Rayyan
- 1
Locate vertical duct routes and main disconnects
Before the visit, confirm the building's vertical duct routes and the location of main disconnect points for each floor.
- 2
Coordinate with construction team and main contractor
Coordinate with the main contractor to set the timeline for electro-mechanical installation and confirm access to ducts, ceilings and building spaces.
- 3
Verify temporary power on each floor
Ensure safe temporary electrical connections are available on each floor for powering installation and testing tools before main supply connection.

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 multi-floor cooling systems in hotels and compounds?
Yes, we design and implement central cooling systems distributed across multiple floors, with smart control panels managing each floor independently and safely.
Do electro-mechanical works delay projects, and how do you keep schedules on track?
We start planning early with the main contractor and coordinate with other trades to install wiring and pumps in parallel with construction, reducing delays.
Does Al Rayyan's hot, dry air affect the electrical wiring?
We use insulation rated for extreme heat and dry conditions, and mount panels away from direct sun and high-temperature areas.
How do you coordinate with other contractors on site?
We join weekly site meetings, provide detailed schedules for electro-mechanical work and sequencing, and ensure our tasks do not clash with other trades.
