Big data in a government infrastructure context may consist of records generated by IoT devices measuring external conditions, condition monitoring, service use, human or transport movement, or records gathered by facility, place or building management systems. Big data is characterised by:
- Volume: the quantity of generated and stored data.
- Variety: the type and nature of data.
- Velocity: the speed at which the data is generated and processed.
- Variability: the inconsistency of the data.
- Quality: the relevance and accuracy of the data.
Monitoring and analysis of live sensor data, captured as big data, will support a better understanding of performance during construction and operation, resulting in smarter designs, requiring less material, reducing carbon and needing less labour for construction, etc.
