In modular construction, it is insufficient for safety management of workers, and workers are still exposed to the risk of accidents due to work at high places for lifting and assembly work in modular construction sites. Therefore, it is necessary when preventive safety management through risk management of workers on modular construction sites. This study is a basic study for the risk assessment(checklist) of modular construction, and the purpose of this study is to analyze the risk factors of the module lifting work at the modular construction site. It is intended to identify the hazard risk factors and improvement measures of the existing lifting operation, by analyzing the case of the risk assessment of the existing RC method, and to identify the risk factors for each work process when lifting the module. In the future, the results of this study are expected to be utilized in the development of checklists for risk assessment as safety management plan for modular construction sites.

The construction industry is undergoing a digital transformation in which Building Information Modelling (BIM) is a key technology. The potential of BIM in several areas such as design optimization, time management, cost management, and asset management/facility management (AM/FM) is widely acknowledged by the AECO (Architecture, Engineering, Construction, and Operation) industry around the world. However, BIM implementation in construction projects is faced with problems such as project delay and cost overruns. The lack of identification of risks in BIM projects and standard guidelines on mitigation techniques furthers poor performance, dissatisfaction, and disputes between employers and project participants, which results in low BIM adoption rates. Therefore, the objective of this paper is to identify the potential risks in BIM implementation under the primary categories - (1) technical, (2) contractual, (3) management-related, and (4) personnel-related risks in BIM projects and present solutions to reduce, manage, and mitigate risks. To meet the objective of this paper, a survey was designed and conducted in the Hong Kong construction industry in which over 140 respondents from different disciplines, with experience in BIM projects, have participated. Based on the analysis of the survey data, the most severe and frequently occurring BIM risks and their potential mitigation strategies were identified and discussed in this paper.

Recently, industrial accidents rate has been gradually decreasing due to the development of safety management methods, but until now, the accident rate in the construction sector is higher than other industries. Large-scale construction sites are operating systematic safety systems to reduce industrial accidents. However, small and medium sized construction sites do not have systematic safety system and lack safety management ability, so that disaster is not reduced compared with large scale construction site. As a result, disaster prevention technology instruction system has been implemented to reduce the disasters of small and medium scale construction sites. However, in the case of a small construction site less than 2 billion won, there is little decrease in the accident rate, and in some cases, the accident rate increases. After the technical guidance system has been implemented, it is necessary to identify the performance and problems of implementation and to improve its effectiveness. In this study, we suggest the improvement plan to improve the efficiency of the technical guidance system by analyzing the problems and actual conditions of technical guidance operation in small and medium sized construction work sites.

Productivity analysis is the most important and significant method for evaluating management and engineering performance during whole project stage. However, it is very difficult in developing qualitative index to construction industry comparing to other industries. Therefore, analytical hierarchy process (AHP) is one of the methods for overcoming these limitations by checking consistency index using duality comparison. In this study, it is scraped up an application plan and selection for innovative tools by analyzing survey results on tool users and site managers with respect to using Modified-AHP performance measurement method.

Facility Management (FM) is a project phase to maintenance and to increase the qualities of product which is planned on the design phase and ensured on the construction phase. In addition, since the approximate time occupied in operation and maintenance phase is the longest from construction project as total approximate cost is about 85% of whole the project, it could be managed and realized primarily. The information of facility is not created on the specific point of project, but it might be created on the whole process of subject project widely. Thus, as the information could not be lost and it can be delivered into computer aided facility management system, it is necessary to manage the facility information. This paper proposed the necessities and the problems of BIM-based data interoperability on the Korean construction projects.
