A building management system brings the plant that heats, cools, lights and monitors a building onto a single interface — so it can be scheduled, trended and alarmed instead of adjusted by hand and forgotten.
The controllers get installed, the graphics get drawn, the system passes its witness test, and then nothing is tuned again. Control loops sit on factory defaults. Schedules never change when the building's use does. The alarm list grows until it is long enough that nobody reads it, at which point the system has stopped being useful while still being expensive.
In a climate like the Kingdom's, that drift is costly. Cooling is the biggest line on most buildings' energy bill, and a chiller sequence that is slightly wrong runs slightly wrong every hour of every day.
So we treat commissioning and post-handover optimisation as part of the job rather than an upsell. A system nobody trusts is worse than no system, because you paid for it.
New installations, and taking over systems that were installed by somebody else and never finished properly.
Points schedule, controller topology, network layout and integration strategy — written so it can be tendered, priced and verified rather than just installed. Getting the points schedule right at this stage is what stops arguments at commissioning.
Air handling units, fan coils, chillers, pumps and VAV terminals. Control sequences written out, setpoints agreed with whoever operates the building, optimum start and stop, and loops actually tuned rather than left where the factory set them.
Scheduling, daylight and occupancy response, zoning, and scene control for public areas and back of house. Set up so overrides are possible without someone defeating the whole schedule to get one room to behave.
Electrical, water and thermal metering brought onto the same system, trended by zone and by plant item. Sub-metering placed where it answers a question you will actually ask, rather than everywhere it is technically possible.
Fire alarm, access control, CCTV, lifts and generators surfaced on the same head-end over BACnet, Modbus or the manufacturer's gateway. Life-safety systems are integrated read-only, so the BMS reports their status without ever being able to command them.
Floor-plan graphics that match the building as built, and an alarm strategy with real priorities behind it. The target is an alarm list short enough that an operator still reacts to it — which means suppressing the noise, not just colour-coding it.
Point-to-point verification, sequence witnessing against the written control descriptions, and trend logs proving the plant behaves across a full cycle. Handover includes the as-built points schedule, O&M documentation and training for the people who will operate it.
After handover: seasonal setpoint and schedule review, trend analysis to catch plant drifting out of tune, and alarm list housekeeping. This is the part that decides whether the system is still earning its cost in year three.
That is a common brief, and a solvable one.
Typically the symptoms are the same: graphics that no longer match the plant, alarms permanently active, half the points reading nothing, and no documentation from the original installer. We start with a survey to establish what is actually connected and working, then give you a written position — what can be recovered, what needs replacing, and what it costs either way.
Sometimes the answer is that the existing controllers are fine and the system needs re-commissioning rather than replacing. We will tell you that even though it is the smaller job.
BMS delivery depends on the manufacturer platform in the building and, for anything touching fire or life-safety interfaces, on the appropriate approvals. Where a project needs a certification or platform accreditation we do not hold in house, we bring in an accredited specialist under our contract rather than working around it.
You keep one contract, one programme and one party answering for it.
