Written by Cube Controls. Posted in Uncategorised

Finding and hiring an external provider for Building Management System (BMS) maintenance can be a daunting experience for technical and non-technical building managers alike. In your role, you’re responsible for ensuring the reliability, efficiency and safety of your building’s systems, which means partnering with a trusted and experienced BMS specialist engineer is crucial. This blog highlights key factors to consider, from verifying credentials and the experience of your chosen engineer to understanding what a typical BMS maintenance checklist includes, and what to expect at the end of the service. By understanding these core elements, non-technical managers, in particular, can make informed decisions, ensuring their BMS remains in top working order.

Tips on selecting your BMS service engineer

A good place to start is by checking your prospective BMS engineer’s certifications and industry experience to ensure they are qualified. Specialists who provide a range of services, including regular inspections, emergency repairs, system upgrades and replacement programmes, will be able to demonstrate a thorough understanding of building management systems. This comprehensive service offering also ensures that all aspects of your BMS is kept in excellent working condition going forwards. You can gauge their reliability and customer satisfaction by checking independent online reviews and client testimonials. Additionally, you could ask for examples of how they have successfully serviced clients with buildings similar to yours. This ensures they have the expertise to handle any special features your building may possess, such as its size and complexity, rural location, occupancy type and/or historical/grade 2 listings, that may impose specific limitations. At the same time, assess their responsiveness to your enquiries and ask about their ongoing availability to handle urgent repairs promptly. Seek clarity about pricing and detailed maintenance service agreements to avoid hidden costs and ensure complete transparency.

Before maintenance begins

Maintenance work will typically include an inspection of the BMS to evaluate its performance. However, an experienced BMS engineer will initiate a discussion with you beforehand, based on how your system and your building have been functioning to date. They’re likely to pose questions such as:

• Have there been any recent upgrades or repairs to the HVAC system?
• Are there any recurring issues with the system?
• Are there any new issues or complaints from staff about the building?
• Have there been any alarms or notifications from the BMS recently?
• Are there any specific areas or zones of your building that need particular attention?
• Are there any upcoming projects or changes that will be made to the building that are likely to impact the BMS?

Having an open exchange about the history and future expectations of your BMS and your building will ensure the BMS service engineer can investigate further.

During inspection

See the BMS maintenance service as a general ‘health check’ for the building in terms of physical features and software performance. The type of checks that are carried out will vary depending on the type of building and BMS. For instance, for larger, more complex buildings that require intricate BMS types, an experienced BMS service engineer will make multiple maintenance service visits throughout the year, focusing on a specific element of the system each time, to guarantee that all elements are assessed in detail. During the inspection process, the engineer will actively search for failing components of the system, assess the need for firmware updates and security patches, and identify discrepancies between the building’s usage and its control, which often results in energy wastage. The engineer will also create and maintain a software backup of the entire BMS system in secure storage, ensuring that any potential catastrophic system failure can be recovered from effectively. Last but not least, the inspection will also look at the physical aspects of the BMS and, in particular, the control panels themselves. Any issues should be duly recorded along with suggested remedial actions. The heating, ventilation and air-conditioning (HVAC) plant will also be assessed for signs of wear and tear or performance problems.

Your easy-reference BMS maintenance checklist

The below BMS maintenance checklist can be used to guide Building Managers in collaborating with their chosen BMS engineer and what to expect from a comprehensive maintenance service: Initial discussion with the BMS engineer:
