Internet of Things (IoT) Technology in Intelligent Construction

The Internet of Things (IoT) plays a significant role in enabling intelligent construction by connecting various devices, equipment, and sensors to the internet, allowing them to collect and exchange data.  IoT technologies enhance construction processes, improve safety, reduce costs, and increase efficiency.

Here’s how IoT is used in Intelligent Construction:

  1. Equipment Monitoring:
    • Condition Monitoring: IoT sensors attached to construction equipment, such as excavators and cranes, track their health and performance in real-time. This data helps in predictive maintenance, reducing downtime.
    • Fuel Efficiency: IoT can monitor fuel consumption and provide insights into optimizing equipment usage, reducing operational costs.
  1. Site Safety:
    • Wearable Devices: Workers wear IntellConstruct’s IoT-enabled wearable like smart helmets and vests that monitor vital signs and detect potential safety hazards. In case of an emergency, these devices can send alerts to supervisors and first responders.
    • Environmental Sensors: IoT sensors can monitor air quality, temperature, humidity, and other environmental factors on the construction site, helping ensure worker safety.
  1. Asset and Tool Tracking:
    • IoT sensors can track the location and status of construction materials, tools, and equipment. This reduces theft, loss, and the need for manual inventory checks.
  1. Site Security:
    • IoT-connected cameras and motion detectors enhance site security by providing real-time surveillance and alerts. These systems can also be integrated with access control and identity management.

 

Types of IoT Products used in Intelligent Construction:

  • Smoke and Fire Sensors: Detect smoke and fire, providing early warnings for fire safety in construction sites and buildings.
  • Humidity Sensors: Measure humidity levels in the environment, which is important for concrete curing and indoor air quality monitoring.
  • Pressure Sensors: Monitor air pressure and water pressure in hydraulic systems, pneumatic equipment, and building systems.
  • Smart Helmets: Equipped with sensors, cameras, and communication capabilities for tasks like video streaming, augmented reality (AR) overlay, and head impact detection.
  • Wearable Exoskeletons: Assist workers in lifting heavy objects, reducing the risk of musculoskeletal injuries.
  • IoT-Enabled Gloves: Include sensors for monitoring hand movements and vibration levels, helping to reduce the risk of hand-arm vibration syndrome.
