Assessing Construction Workers' Vigilance Level Through Wearable Electroencephalography System

Abstract: Construction industry requires constant caution on construction labors when they expose to hazardous environments. Although received fundamental safety training, construction workers tend to insensitive to hazards because of their long time exposures to risks. Many construction workers take unsafe behavior when they wrongly estimated the potential risks. Therefore, the discrepancy between the environment risks and workers' perceived risks is the major cause of unsafe behaviors. However, current assessing approaches are subjective and post-hoc. In this paper, we proposed a wearable Electroencephalography (EEG) system to quantitatively and objectively assess the construction workersŐ vigilance level for perceived risks. With such data acquisition approach, the construction workers' risk perception can be further understood and guide the safety training programs in future.

Digital Tools for the Construction Site. A Case Study: ACCEPT Project

Abstract: Construction projects often encounter problems related to scheduling reliability and to a mismatch between the expected and actual building performance. In order to reduce these problems, the ACCEPT project is developing an ICT system to manage construction works more efficiently by applying Lean Construction principles, to increase the quality of executed works by implementing interactive checklists and sensors, and to share information in real-time among different stakeholders. In the ACCEPT system, existing technologies such as Augmented Reality, BIM, mobile/wearable devices and sensors have been combined together to create an innovative ICT solution for construction management. The ACCEPT system consists of three interconnected applications: SiMaApp for mobile devices CoOpApp for smart glasses and Dashboard for PC. The main goal of this research paper is to describe the framework of the ACCEPT system and its applications.
