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 Mahamid is a modern medical and residential zone with hospitals, clinics and multi-storey residential blocks, with strict health requirements for air quality, temperature, humidity and sterility. Medical facility electro-mechanical systems need higher control precision, advanced filtration, enhanced electrical isolation and backup power and cooling systems, plus close coordination with smart building management and biomedical engineering teams because the systems are interconnected.
Al Mahamid sits east of Jeddah, a modern medical and residential zone with advanced hospitals and clinics alongside residential blocks.
Most medical facilities in Al Mahamid use high-precision central cooling systems with backup units and advanced control systems that are redundant or run in parallel.
The AC setup in Al Mahamid
- 1
High-precision central cooling systems for medical use
Large medical facilities in Al Mahamid use advanced cooling units with high capacity and very precise control in each sensitive zone, such as operating theatres and intensive care.
- 2
Parallel backup units and automatic failover switches
The main system is duplicated or run in parallel with a full backup unit, and automatic switching systems instantly move to the backup if the main fails, with regular reliability testing.
- 3
Enhanced electrical isolation and advanced protection
All sensitive electrical circuits are protected with isolation transformers, advanced protection switches and continuous monitoring devices, with precise documentation of standards applied and regular testing.
Before the visit
Before our visit in Al Mahamid
- 1
Obtain complete medical and engineering drawings
Provide us with all engineering and medical drawings, including maps of sensitive zones (theatres, care, labs), plant room locations, and control and precision requirements for each area.
- 2
Coordinate with biomedical and facilities management teams
Meet with us, the biomedical team and chief engineer to understand medical requirements and regulations, appoint coordination points and responsibilities, and schedule testing and calibration.
- 3
Schedule the work carefully to avoid disrupting services
If the medical facility is operating during construction or upgrade, agree a flexible schedule that avoids critical service times, and use temporary backup units if needed to ensure service continuity.

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.
Hospitals need high precision in temperature and humidity, how do you achieve this?
We use precise, dynamic sensors in each zone, set systems to the tightest allowable ranges, and monitor performance with an advanced system that alerts immediately to any small deviation from required limits.
Medical systems are complex and require backup, do you have reliable solutions?
We design systems with independent or parallel backup units and automatic failover switches, and coordinate closely with the biomedical team to ensure compatibility and thorough testing before commissioning.
Medical facilities need strong electrical isolation, how do you handle this?
We use standard electrical isolation transformers and advanced protection devices on all sensitive circuits, conduct periodic isolation tests, and follow international standards for electrical safety in hospitals.
Medical systems may change or expand, what flexibility do you offer?
We design runs and piping with spare capacity headroom, install expandable reserve connection points, and document all systems clearly to enable future modifications and additions without disrupting current operations.
