AFE AFE Technology & Innovation in Facilities 1 — Questions and Answers
Question 1: What does the acronym 'BIM' stand for in the context of facilities engineering and construction?
- Building Information Modeling (Correct answer)
- Building Infrastructure Management
- Baseline Integration Metrics
- Building Inspection Manual
Correct answer: Building Information Modeling
Building Information Modeling (BIM) is a digital representation of a facility's physical and functional characteristics used throughout design, construction, and operations.
Question 2: Which technology platform is commonly used by Facilities Engineers to manage work orders, preventive maintenance schedules, and asset inventories?
- Geographic Information System (GIS)
- Computerized Maintenance Management System (CMMS) (Correct answer)
- Building Automation System (BAS)
- Enterprise Resource Planning (ERP) — finance module only
Correct answer: Computerized Maintenance Management System (CMMS)
A CMMS is purpose-built to track assets, schedule preventive maintenance, dispatch work orders, and capture maintenance history for facilities operations.
Question 3: In a Building Automation System (BAS), what is the primary function of a Direct Digital Controller (DDC)?
- To generate monthly utility bills
- To monitor and control HVAC and other building systems using programmed logic (Correct answer)
- To provide wireless internet access throughout the building
- To manage access control and security cameras
Correct answer: To monitor and control HVAC and other building systems using programmed logic
A DDC is a microprocessor-based controller that executes control sequences for HVAC, lighting, and other building systems based on sensor inputs and programmed algorithms.
Question 4: What is 'predictive maintenance' in facilities engineering?
- Performing maintenance on a fixed calendar schedule regardless of equipment condition
- Using condition monitoring data and analytics to predict failure and perform maintenance just before it is needed (Correct answer)
- Repairing equipment only after it fails
- Replacing all equipment every five years as a standard policy
Correct answer: Using condition monitoring data and analytics to predict failure and perform maintenance just before it is needed
Predictive maintenance uses real-time condition data (vibration, temperature, oil analysis, etc.) and analytics to forecast when equipment will fail and schedule maintenance accordingly.
Question 5: Which IoT application in smart buildings automatically adjusts lighting levels based on occupancy and available daylight?
- Variable frequency drive (VFD) control
- Daylight harvesting with occupancy sensors (Correct answer)
- Chilled water reset strategy
- Demand-controlled ventilation
Correct answer: Daylight harvesting with occupancy sensors
Daylight harvesting combines photosensors and occupancy sensors with dimmable lighting controls to reduce electric lighting energy when sufficient natural light is available.
Question 6: What is the primary benefit of integrating a Building Information Model (BIM) with a CMMS for facilities operations?
- Eliminating the need for preventive maintenance
- Linking visual 3D asset data to work order and maintenance records for faster identification and response (Correct answer)
- Replacing all paper drawings permanently
- Automating payroll for maintenance technicians
Correct answer: Linking visual 3D asset data to work order and maintenance records for faster identification and response
Integrating BIM with a CMMS allows maintenance staff to locate assets visually in a 3D model and instantly access associated maintenance history, manuals, and work orders.
