3. Building technical systems and facility items subject to maintenance
A successful building maintenance programme covers all critical building systems. Depending on system complexity and regulatory requirements, some assets may require specialist technical maintenance services delivered by certified contractors. The following systems are among the most important to monitor and maintain as part of an effective maintenance strategy.
Electrical systems support lighting, lifts, HVAC, pumps, BMS, and security. Maintenance should focus on safety, power continuity and operational risk control, especially in areas with potential overload or overheating risks.
A clear electrical maintenance plan helps avoid service disruption for owners, residents, tenants and building users.
- Water supply and drainage systems:
his infrastructure comprises pumps, storage tanks, pipelines, valves, sanitaryware, as well as rainwater and wastewater drainage systems. Maintenance focuses on sustaining stable water pressure, controlling leaks, and preventing blockages. Concurrently, tracking breakdown histories and pump operational efficiency forms the baseline for optimising maintenance schedules and forecasting long-term repair requirements.
- Building management systems (BMS):
The BMS serves as the central hub for monitoring and controlling technical systems via a unified platform. Maintenance of this system encompasses both software and associated hardware, including sensors, controllers, control panels, signal transmission lines, and display interfaces. The objective is to ensure accurate, continuous operational data to effectively support decision-making processes.
- Lift and escalator systems:
Lifts and escalators are high-frequency equipment classes that directly impact safety and the transit experience within a building. Consequently, maintenance efforts must focus on critical components such as cabins, landing doors, control systems, traction machines, safety brakes, rescue devices, and warning signals.
For lifts, in addition to routine maintenance recommended by manufacturers or specialist contractors, the Management Board must track statutory safety inspection schedules in compliance with current regulations. Proper management of maintenance records, statutory inspection histories, and occupant feedback facilitates the early detection of anomalies, reduces operational downtime, and ensures lifts consistently meet safety requirements during utilisation.
Backup generators play a vital role in maintaining electricity for critical systems during power outages or grid supply disruptions. Maintenance tasks typically involve fuel, batteries, cooling systems, lubricating oil, transfer switches, and load-bearing operational capacity.
For buildings with continuous operational mandates, periodic load-testing and recording operational outcomes are essential for assessing system readiness. However, load-testing frequency and inspection scopes must align with manufacturer recommendations, system characteristics, and the specific operational requirements of each property.
- Air conditioning and ventilation systems (HVAC) :
HVAC systems directly influence occupant comfort, indoor air quality, and energy expenditures. Monitoring HVAC efficiency enables the management board to control energy costs and mitigate the risk of premature equipment deterioration.
- Firefighting and fire prevention systems :
Firefighting and fire prevention systems constitute a top-priority category in any building maintenance plan, given their direct bearing on occupant safety and the lawful operation of the property. Equipment such as fire alarms, sprinklers, fire pumps, extinguishers, hydrants, emergency exit signs, and smoke extraction systems must undergo periodic inspections to ensure constant readiness in the event of an incident.
In day-to-day operations, the role of the Management Board extends beyond on-site equipment checks to encompass tracking maintenance schedules, inspection logs, servicing results, and coordinating with specialist contractors when required. Maintaining comprehensive fire safety records enables the building to better control risks whilst complying with current statutory requirements and safety standards.
- Security and CCTV systems:
Security systems typically comprise CCTV, access control, alarms, barriers, intercoms, and public area surveillance solutions. Absent proper maintenance, risks may manifest in recording capabilities, data storage, access control, or incident response efficacy.
Security maintenance requires a combination of physical equipment checks and audits of software, data, and access permissions. In modern buildings, integrating security data with the BMS or operational platforms can enhance the surveillance and response capabilities of the management team.
- Network systems and technological infrastructure:
This infrastructure encompasses local networks (LAN), internet connectivity, signal cabling, server rooms, network equipment, communication setups, and operational digital platforms. In office buildings, shopping centres, or mixed-use complexes, the continuity of technological infrastructure is increasingly critical to the user experience and operations management capabilities.
Maintaining this asset group demands close coordination between the operations department, technology vendors, and information security units where applicable. Beyond equipment inspections, attention must be paid to scalability, redundancy, access security, and connection stability.
Whilst most maintenance tasks are executed by the project’s on-site technical personnel, certain more complex categories involve statutory obligations or require specialist expertise beyond the team's capacity. For instances such as lift maintenance, electrical substations, or fire safety systems, the project may enter into service contracts with external specialist companies.
