We design, supply, program and commission building management systems (BMS) for offices, banks, hospitals, pharmaceutical sites, universities and hotels across Saudi Arabia, and we upgrade and maintain existing systems, so your building runs more efficiently at a lower operating cost.
Free consultation and free site visit in Riyadh
Whether the building is under construction or already in operation, we step in where you need us and take it to a system that works as it should.
No need to chase every detail yourself. We price from the IO list or drawings, prepare the submittals, and coordinate with the mechanical and electrical contractors until the consultant approves testing and commissioning and the system is handed over. One party responsible for the building management system on your project, from start to finish.
BMS installation and commissioningMissing graphics, points offline, alarms that reach nobody, and the building pays for it in energy use and repeat breakdowns. We audit the system point by point, give you a clear fault report with a corrective plan, then bring the system back to working order and maintain it.
BMS maintenance and repairUPS units, precision cooling, meters and leak detection each sit on a separate panel that nobody watches until something fails. We connect them all to the building management system, so their readings and alarms appear on one screen and any fault reaches the on-call engineer immediately.
BMS integrationA building management system is the brain that runs a building’s cooling, lighting, pumps and other services from one place. It works in a continuous four-step cycle:
These parts talk over one network using open communication protocols, so equipment from different makers works as one system (BACnet, Modbus).
Plant runs only when needed, setpoints stay at the right values, and chilled water and airflow follow the actual load.
Alarms and trend logs reveal a failing pump or a drifting temperature early, so maintenance is planned, not reactive.
HVAC, lighting, meters, UPS and life-safety status on one platform, available to the team wherever they are.
Hire us for one stage or for the whole BMS package. Either way, every stage ends with a clear document you can review and approve, so you always know where the work stands.

Successful integration takes more than protocol support. Each manufacturer implements BACnet and Modbus a little differently: register maps have gaps, addressing starts from 0 or 1, word order for 32-bit values varies, and some Modbus TCP devices accept only one client. Knowing these details is what makes integration work the first time. We have integrated the devices below on delivered projects.
| System | Equipment | Connection |
|---|---|---|
| UPS | Eaton 93PS UPS | BACnet/IP |
| Precision cooling | Montair CRAC units, MCX controllers | Modbus RTU |
| Energy meters | Schneider PM5340 / PM2120 power meters | Modbus RTU (RS-485) |
| Leak detection | TTK FG-NET leak detection | Modbus TCP |
| Aspirating smoke detection | ModuLaser aspirating smoke detectors | Modbus TCP |
| Isolation transformers | Isolation transformers, thermal protection contacts | Modbus + Dry contacts |
| Fan coil units | FCUs via the AC central controller | BACnet/IP |
| Water and BTU meters | Water and BTU meters | Gateway |
| Life safety (monitoring only) | Fire alarm panel, gas suppression, PA system | Dry contacts |

Equipment not listed? Send us the model and its BACnet PICS or Modbus register map, and we will tell you which points can be read and written.
Alongside third-party equipment, the BMS controls the main building plant directly from its own controllers.
Start, stop and sequence chillers to the load, and monitor chilled water supply and return temperatures and faults.
Chillers · SequencingRun pumps in rotation to share running hours, and control their speed to hold the required pressure.
Pumps · VFD · Duty / StandbyMonitor roof and ground tank levels, run the transfer pumps, and alarm on low level or overflow.
Water Tanks · Level ControlRun to schedule, hold the set temperature, and monitor compressor status and faults.
Package UnitsControl supply air temperature, fresh air dampers and fan speed, and monitor filter condition.
AHU · FAHURun heaters to schedule and set temperature, and monitor their status and faults.
HeatersOn/off switching, dimming, and time schedules for each zone based on working hours.
Lighting · On/Off · Dimming · SchedulesRun toilet, kitchen and car park fans to schedule or to air quality readings.
Exhaust & Ventilation FansMonitor generator status and fuel level, breaker status, and energy meter readings.
Generators · LV Panels · MetersAn alarm helps only if someone sees it. At night and on weekends the control room is often empty, so we send alarms to the phones of the people on duty.
The principle is the same, but every sector has different priorities. That is why we design monitoring and alarms around what matters to each client.
Offices, a trading floor, and server and electrical rooms, with critical equipment monitored around the clock and alarms sent straight to the on-call engineer.
Open-plan offices, meeting rooms and server rooms, with HVAC and lighting run to working hours.
A building management system for the head office floors, controlling HVAC across all spaces to keep conditions steady and the workplace comfortable for staff.
A monitoring system that tracks the HVAC equipment and room conditions, and shows any fault to the operations team as it happens.
Kitchen extract balanced against fresh air, keeping the dining area comfortable and free of kitchen odours.
Our engineers took part in the building management works on the project, following NEOM requirements for testing, documentation and handover.
One of our recent projects, in the same detail we present to consultants.
An office floor with a trading area, server rooms and electrical rooms, where a cooling or power fault must be seen within minutes. The critical equipment came from different manufacturers, each with its own controller.
The BMS now covers:
The graphics follow how the facility team works. There is a home page by system, one page for each electrical panel with breaker status and meter readings, and alarms in five classes from life safety to system health.
BMS quotations are hard to compare when each company draws the line in a different place. Ours state clearly what is included and what is not, so there are no surprises after signing.
We can include these too. Mention it when you request the quotation.
Consultants in the Kingdom write BMS specifications around the Saudi Building Code and, more and more, the Mostadam green building rating. We prepare our work and documents for both, and carry it out to ISO requirements for quality, environment and safety.
We program schedules, setpoints and HVAC control sequences to the project specification, which the consultant bases on the Saudi Building Code, including the energy conservation code SBC 601/602.
Mostadam awards points for energy metering, systems commissioning and building performance monitoring. A BMS with meters, trend logs and documented commissioning provides the evidence for those points.
Submittals, point-to-point sheets, functional test reports and as-built drawings, prepared in English or Arabic for consultant review and handover.
Our work follows the requirements of ISO 9001 for quality management, ISO 14001 for environmental management and ISO 45001 for health and safety on site.
We supply, program and commission systems from all three. We also work on the controllers already installed in many Riyadh buildings, so you can upgrade or extend your existing system instead of replacing it.
Devices that support these protocols, such as UPS, CRAC units, chillers and meters, are integrated with any of the systems above.
Questions we get from consultants, contractors and facility managers, with direct answers.
We do not push a particular platform. We deliver to the approved project specification, and our engineers have installed and commissioned Johnson Controls, Honeywell and Siemens systems as well as Niagara-based systems. Where the specification is open, we recommend the platform that suits the building size and budget.
The points schedule if it is ready, or the mechanical, electrical and control drawings, together with the controls section of the specification. If there is no points schedule, we take off the points from the drawings and send it to you for review before pricing.
We define the scope item by item, because this is where quotations differ most: controllers and panels, field devices (sensors, valves and actuators), cabling and containment, programming and graphics, testing, commissioning and training. The quotation can be limited to controllers and programming when the contractor supplies the field devices and installs the cabling. Prices are in Saudi riyals, 15% VAT is shown separately, and quotations are valid for 15 days.
We prepare the programming and graphics during installation. Testing and commissioning need the mechanical equipment installed and on permanent power, and the cabling complete and tested. We give the contractor a readiness checklist early, so commissioning is not delayed at the end of the project.
As-built drawings, the final points list, signed point-to-point test sheets, backups of the station and controller programs, licence details, administrator accounts, and the O&M manual, plus training for the operations team.
In most cases, yes. We start with an inspection visit to establish what can be recovered through the manufacturer or the licence holder, and what needs reprogramming. You then receive a written report on the system condition, with the proposed works and their cost, before any work begins.
Yes, if the device supports BACnet or Modbus, or provides dry contacts. Some devices need a communication card ordered separately from the manufacturer, so it is worth confirming this before procurement. Send us the model with its register map or BACnet PICS, and we will confirm the available points before installation.
The alarm goes to the on-call person for the shift by phone call, SMS, WhatsApp or email, and escalates to the next person if it is not acknowledged. For critical signals, a hard-wired autodialer can be added that keeps working if the network or the main station is down, as long as the controller is running.
Yes, through annual contracts covering scheduled visits, review of alarms and offline points, updated backups, sensor reading checks, and remote support when needed. We also maintain systems we did not install.
We recommend separating the BMS network from the corporate network, never exposing the station directly to the internet, and allowing remote access only through a VPN managed by your IT team, with an individual account for each user. We coordinate these settings with your team during the project.
Yes. The initial consultation and site visit are free within Riyadh. After the visit we define the scope and send the quotation.
The first consultation and a site visit inside Riyadh are free. Tell us what you need and we reply within one working day.
