RETRACTED ARTICLE: Exposure Assessment for Roller Compacted Concrete Dam Construction Integrated Real-Time Location Information

Abstract

Roller compacted concrete (RCC) dam projects are generally initiated in dynamic environment, where space conflicts occur frequently. Construction workers are often exposed to dangers posed by activities performed by teams other than their own. Therefore, it's critical for construction security to conduct fairly precise exposure assessment. Several research studies have been proposed to address this site safety issue. Despite their valuable contributions, few of them have noticed that, for some construction processes, their hazard scope may exceed the work space. Another limitation is that most traditional methods expound space factor and time factor separately rather than comprehensively. Accordingly, the present paper proposes a novel method to quantify exposure frequency integrated with the real-time location information of three-dimensional cross activities. Combined with the construction process cycle and the operation time characteristics, conflicts between impact space and work space are determined in real time, which is more accurate as the interaction between construction activities is certain at each moment. With a reliable assessment of hazard exposure levels, construction managers will be able to provide solutions to reduce hazards to acceptable levels.
