Smart & Connected Construction

To remain competitive, the construction industry in the U.S. requires a highly-trained and diverse workforce. The Virtual Interactive Construction Education project uses cyber-infrastructure tools to transform traditional subject-based lectures into project-based, interactive simulations in order to improve the quality and efficiency of undergraduate education. The learning modules place students in the full context of running a construction project in a computer-generated simulation environment. The project uses the simulation module along with assessment tools to determine the effectiveness of the module for student learning and engagement.

The dynamic nature and limited work space of roadway work zones contribute to the dangerous work environment for construction workers. These characteristics can create hazardous proximity situations because pedestrian workers are required to operate in close proximity to heavy construction equipment. A total of 609 work zone personnel fatalities were experienced in 2012. Previous analysis of work zone fatality data found that of the pedestrian worker and mobile object struck-by fatalities, a majority resulted from pedestrian workers being struck-by construction equipment. These statistics indicate that current safety practices for pedestrian workers and equipment operators are inadequate. The objective of this study was to create and evaluate a proximity detection and alert system using Bluetooth sensing technology. The scope is hazardous proximity situations between pedestrian workers and construction equipment in roadway work zones at grade. Many evaluation metrics were implemented to assess the tested proximity sensing systems including the cost, time and ease of calibration, required hardware, system capabilities, and many others. Commercially available RFID and magnetic field proximity sensing systems were also evaluated to provide a basis for comparison. Various interaction scenarios between pedestrian workers and construction equipment were used in the evaluation of the system. Experimental results demonstrate that the created proximity detection and alert system 1) requires minimal infrastructure, 2) provides adequate alerts to equipment operators and pedestrian workers, and 3) provides additional layers of hazard avoidance in real-time during hazardous proximity situations in roadway work zones.

With enormous technological changes over the last decade, modern construction trends have become more complex and dynamic. This demands that construction professionals be more effective and organized to successfully complete their construction activities. However, recent research shows that current construction management techniques are ineffective. In addition, this research recognized the potential benefits of location awareness of construction resources in the construction management. The availability of location awareness information was identified to assist real-time decision making, provide more control over construction processes, and improve productivity and safety. Our group is interested in developing a low-cost, effective tracking system. This would be the first step forward in realizing construction management tools that leverage location awareness of construction resources.
