Purpose: Facilitates easy movement between building floors
Components: Elevators, escalators, lifts, control systems
Importance: Enhances accessibility, safety, and occupant satisfaction
Routine Inspections: Schedule regular inspections and maintenance to ensure safe and reliable operation of elevators and escalators.
Safety Features: Ensure all safety features, such as emergency stop buttons and alarms, are functional and accessible.
When inspecting the health of the system, take a close look at these items:
Ride quality smooth
No frequent shutdowns or entrapments
Modernization assessment done within last 5 years
Emergency phones functional
Regular testing and inspection current
Items that should be called out in the preventative maintenance scope:
Monthly technician check
Record all faults or shutdowns
Listen for delays, jerking, or tenant complaints
Security and Access Control Systems
Purpose: Controls and monitors building entry, ensuring security
Components: Surveillance cameras, card readers, door locking systems, security alarms
Importance: Maintains building safety, reduces liability, and protects assets.
Surveillance Monitoring: Regularly monitor and maintain surveillance cameras and access control systems to ensure they are functioning correctly.
Access Policies: Implement and enforce strict access control policies to protect against unauthorized entry and enhance security.
Building Management Systems (BMS)
Purpose: Centrally controls and monitors all building systems
Components: Sensors, software interfaces, automation controls
Importance: Optimizes building performance, energy use, and operational efficiency.
System Integration: Integrate all building systems into the BMS for centralized monitoring and control, improving efficiency and response times.
Data Analysis: Use data collected by the BMS to identify trends and areas for improvement in building performance and energy use.
When inspecting the health of the system, take a close look at these items:
All devices online and responsive
Setpoints and schedules verified
Sensor calibration checked
Software updated
Alarms and trends monitored
Integration with HVAC, lighting, and fire systems functional
Items that should be called out in the preventative maintenance scope:
Quarterly override report review
Verify communication between devices
Watch for alarms not clearing or override abuse
Roofing Systems
Purpose: Protects building interior from weather elements
