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 Ala is a growing north-eastern zone with residential projects, hotels and tall commercial buildings, so electro-mechanical works here demand complex planning because hotels and large buildings use multi-zone, multi-level AC systems. A team versed in heavy electrical loads, large pumps, thick copper piping and long vertical runs in towers is essential to prevent commissioning failures.
Al Ala sits in Jeddah's north-eastern sector, a modern growth area housing hotels and tall commercial and residential towers.
Major projects here employ AC systems with heavy-duty pumps, multiple control wire runs and main panels rated for very high electrical loads.
The AC setup in Al Ala
- 1
High-capacity main control panel
Hotels and tall buildings need a powerful main panel managing multiple AC zones and independent subsystems with multi-level electrical protection.
- 2
Vertical pipe and cable runs through tower shafts
Copper pipes and electrical cables extend from the plant room to tower roofs through dedicated shafts with robust supports and fixings.
- 3
Dual pump systems with automatic switchover
Large projects use dual pumps with automatic switchover wiring, so backup pump activation occurs automatically if the main pump fails.
Before the visit
Before our visit in Al Ala
- 1
Request complete engineering drawings from all disciplines
Obtain architectural, electrical, mechanical and contractor drawings before the first visit to identify potential clashes between systems early.
- 2
Confirm completion and inspection of the main concrete structure
Verify the concrete structure is complete and formally inspected, and that the site is safe for working at heights and accessing vertical shafts.
- 3
Confirm primary and secondary plant room locations
Tell us where the main plant room is in the lower level and any secondary rooms on intermediate floors, so we can plan distances and loads precisely.

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 handle the high electrical loads in hotels and tall buildings here?
We consult the project's electrical engineer beforehand to calculate the total load from pumps, fans and compressors, then select panels, switches and cables rated appropriately.
The towers here are very tall, how do you run pipes and cables vertically?
We use dedicated vertical ducts and heavy-gauge copper pipes run from the plant room in the lower level to units above, with secure supports and expansion joints to prevent stress and vibration.
Does coastal humidity affect the electrical connections and piping?
Yes, high coastal humidity in Al Ala accelerates copper and connection corrosion, so we use corrosion-resistant connectors and protective coating on pipes.
When should electro-mechanical works start on a tall tower project?
Start after the main concrete structure is complete and inspected, before interior walls and ceilings are fitted, to ensure safe and easy worker and material access.
