BMS Installation Works
BMS installation works cover field sensors and actuators, DDC panels, the controller network, the supervisory server and workstation, plus cabling and containment, priced from the point list. Built to ISO 16484 and BACnet (ASHRAE 135) in Riyadh, Jeddah, Dammam and Khobar, with shop drawings, I/O schedules, test records, controller backups and O&M manuals at handover.
A BMS installation package is the physical and logical build of a building's control system. It holds the field sensors and actuators on the plant and in the ceiling void, the DDC panels that read them and run the logic, the controller network between panels, a supervisory server with a workstation, and the cabling and containment that tie everything together. NLS Contractors takes it as a works package: supply and install, programming, testing and handover.
The price starts from the point list. A point is one signal the system reads or drives. Analogue inputs (AI) carry values such as temperature, pressure and flow. Analogue outputs (AO) position a valve or set a drive speed. Digital inputs (DI) read a status or an alarm contact, and digital outputs (DO) start or stop a fan or pump. Integrated points are values pulled from another system through a gateway, for example a chiller panel or an energy meter. Each point carries a device, a cable run, a share of panel I/O capacity, programming time and a test, which is why the BOQ point count by type drives the quote. Floor area does not.
The controls specification normally cites the ISO 16484 series for building automation and BACnet (ISO 16484-5, ASHRAE 135) for the network, and it attaches the consultant's sequences of operation. The offer follows the specification clause numbering and lists what is in and what is out: panels, power supplies, field devices, software licences, graphics, programming and training. Gaps in the sequences are raised as written clarifications before the price is fixed, not absorbed into a lump sum.
Handover is a defined set: shop drawings, panel and I/O schedules, point-to-point test records, controller programs and backups, as-built drawings, O&M manuals and operator training. Testing and commissioning take site time after the other trades think they have finished, so the programme should show it.
To price a BMS package in Riyadh, Jeddah, Dammam or Khobar, send the point list or BOQ, the controls specification clauses, the number of buildings and floors, the protocol, any third-party integrations and the programme dates. Price and lead time depend on the scope, and the offer states both. Where the package includes supply, controls hardware can be offered through NLS Power (nlspower.com) in the same quotation.

Frequently Asked Questions
What counts as a point on a BMS BOQ?+
One signal the system reads or drives: a temperature sensor, a valve command, a pump status, an alarm contact, or a value read from another system through a gateway. The BOQ lists them by type (AI, AO, DI, DO, integrated).
What should I send to get a BMS quotation?+
The point list or BOQ, the controls specification clauses with sequences of operation, the number of buildings and floors, the protocol, any third-party integrations and the programme dates. Drawings help but the point list sets the price.
Can you install a BMS when the controllers are already bought?+
Yes. Installation, programming, testing and handover can be priced on client-supplied controllers and field devices. The offer lists the items it assumes are supplied by others and the date they are needed on site.
Who writes the sequences of operation?+
The consultant, in the controls specification. NLS Contractors programs to those sequences and raises any gap or conflict as a written clarification before pricing, so the programmed logic matches the contract documents.
Who supplies BMS Installation Works in Saudi Arabia?+
NLS Contractors (Northlane Solutions Company) supplies BMS Installation Works across Saudi Arabia, including Riyadh, Jeddah, Dammam and Jubail. Send your specification and quantities to info@nlscontractors.com or info@northlanesolution.com for a quotation.
