“…With location awareness, they can be more efficiently managed and properly incorporated in construction processes. For example, construction personnel often get situated in a hazardous work environment during dynamic construction operations, such as hazardous proximity situation [8], and general safety related situations. With properly implemented automated systems, hazardous situations can be recognized in advance through alerting systems [8] and scene visualization [9]- [11].…”

This research presents the development of a self-governing mobile robot navigation system for indoor construction applications. This self-governing robot navigation system integrated robot control units, various positioning techniques including a dead-reckoning system, a UWB platform and motion sensors, with a BIM path planner solution. Various algorithms and error correction methods have been tested for all the employed sensors and other components to improve the positioning and navigation capability of the system. The research demonstrated that the path planner utilizing a BIM model as a navigation site map could effectively extract an efficient path for the robot, and could be executed in a real-time application for construction environments. Several navigation strategies with a mobile robot were tested with various combinations of localization sensors including wheel encoders, sonar/infrared/thermal proximity sensors, motion sensors, a digital compass, and UWB. The system successfully demonstrated the ability to plan an efficient path for robot's movement and properly navigate through the planned path to reach the specified destination in a complex indoor construction site. The findings can be adopted to several potential construction or manufacturing applications such as robotic material delivery, inspection, and onsite security.

“…Many technologies have been applied for resource tracking in construction, such as passive RFID (Costin et al, 2012), ZigBee (Liu et al, 2007), BLE (Zhao et al, 2017), (Dror, 2018), magnetic field (Park et al, 2016), and Global Positioning System (GPS) (Alarifi et al, 2016). GPS is a mature technology for tracking, but it is not suitable for indoor positioning (Liu et al, 2007).…”

“…GPS is a mature technology for tracking, but it is not suitable for indoor positioning (Liu et al, 2007). For indoor positioning, among all the technologies, Bluetooth Low Energy (BLE) has proved to be cost-effective because of its high degree of implementation simplicity with minimal infrastructure and ease of calibration (Park et al, 2016), and sufficiently accurate, thus making it, from the implementation perspective, the preferred technology. However, different solutions applying BLE technology have neither been thoroughly discussed nor compared for application to the scope of production control in lean construction.…”

Automatic resource location monitoring in construction projects empowers managers to make data driven decisions that improve project workflow. Monitoring data can be processed to measure workflow quality and thus for better understanding of effectiveness and efficiency. We compare two methods for deployment of Bluetooth Low Energy (BLE) beacons for indoor resource monitoring -mobile beacons and fixed gateways (MB) vs. fixed beacons and mobile gateways (FB). BLE beacons can be fixed to walls or carried by workers, and can be fixed to material containers and equipment. Using gateways, such as raspberry pi computers or smartphones, one can easily and automatically monitor resource locations. Several field experiments were conducted, both in the laboratory and in construction sites in Finland, Israel, Peru, Netherlands and China. Technical aspects such as setup, direct cost, feasibility and accuracy were compared for two methods -mobile beacons and fixed gateways vs. fixed beacons and mobile gateways -and the performance of each method in providing the data needed for lean construction workflow assessment was assessed. Both methods are effective in monitoring resource locations but differ in their feasibility of implementation in construction sites and in the utility of the data they provide in terms of identifying value adding activities.

“…In [9], the sensing technologies such as Radar, video camera and Radio Frequency Identification (RFID) have been discussed as measures to implement the collision warning system by monitoring. In [3], magnetic, RFID, and Bluetooth Low Energy (BLE) technologies are discussed as potential candidates for proximity detection. These technologies were compared in terms of their performance in average distance estimation and proximity detection.…”

Over the last decade, the rate of fatality of workers in construction work zones has been of serious concern. One of the most frequent accidents happens due to a ground worker being struck by construction equipment. A major reason behind this is the inability of equipment operators to be aware of the existence of the nearby pedestrian worker. In this paper, we propose a direction aware proximity detection and alert system. The proposed system can detect hazardous situations caused by proximity between equipment and the ground workers. Upon detection, it notifies both the ground worker and equipment operator with audible alerts and visualization of the relative location of the hazard. This research utilizes a recent Bluetooth low energy technology to build a proactive proximity and alert system. To evaluate the effectiveness of the system, outdoor tests were conducted. The obtained results show that the equipment operators can efficiently obtain the information on potential hazardous situations to avoid collision with the ground worker.
