An analysis for the causes of accidents of repair, maintenance, alteration and addition works in Hong Kong
ABSTRACT This study unveils causes of accidents in repair, maintenance, alteration and addition (RMAA) work. RMAA work is playing an increasingly important role in developed societies, including Hong Kong. Safety problems associated with RMAA work in Hong Kong has reached an alarming level. In view of rapid expansion of the RMAA sector and rising proportion of accidents in the construction industry, there is a pressing need to investigate causes of RMAA accidents. Structured interviews were conducted with RMAA contractors to explore causes of accidents in the RMAA sector. A two-round Delphi method with 13 safety experts was subsequently employed to verify the interview findings and rank the relative degree of importance for various causes of accidents. Accidents happen in RMAA work due to intersection of reasons. One of the root causes of accidents in RMAA works is low safety awareness of RMAA workers; however, wider organizational and industrial factors are not negligible. This study sheds light on why accidents happen in the RMAA sector. Only when the factors leading to accidents are identified can effective measures be made.

ABSTRACT: Technology application is deemed an effective way to further construction safety management. Various technologies have been adopted for construction safety, including information communication technology (ICT), sensor-based technology, 3S (GIS/GPS/RS) technology, radio frequency identification (RFID) and virtual reality. A review of previous studies in the area of technology applications for construction safety would be indispensable for the main stakeholders in this field to share innovative research findings and gain access to future research trends. A three-step method was used to obtain relevant publications (119 papers met the ultimate selection criteria) and compile a database of the findings. The results present a general review of technology application for construction safety from the aspects of number of papers published annually, publication type, publication name, country/region of distribution, research level, project phase and project type. Corresponding analysis was performed with the collected data and the radar chart was used for analysing the trend of technology application for construction safety and the trend of research topics. Five research gaps were identified in the review process. The trends and gaps can serve as motivation for researchers and practitioners to work on the next generation of studies and the development of future effective measures, which can ensure a safe construction environment.Construction Management and Economics 06/2013; 31(6):606-622.
