Many studies regarding construction safety management have been conducted. However, it is insufficient to research on external construction site. As a result, ordinary people around the construction site have injured and have a negative view when they think construction industrial since it has regarded having an overfull industrial accidents on media. To break the stereotype and prevention of accident on construction industry have been emphasized at this point in time, it is necessary to establish a comprehensive safety management system which is considered not only internal safety management but also external safety management. Therefore, the objective of this study is to develop the human accident risk quantification model by utilizing the third party payout data which occurred by incomplete safety management on external construction site. This study is conducted as a basic study for developing safety management manuals on internal·external construct site. In the future, it is expected to be used as a reference.

Quality management work at construction sites demands substantial time and effort, involving the preparation of documents in Excel, approval processes, and the execution of quality tests. These Excel-based tasks include printing quality test reports, performing quality tests, generating and approving test reports, and preparing management ledgers. This division of processes extends the duration of work and diminishes efficiency. Accordingly, a cloud-based construction site quality management system was developed to enhance the productivity of quality management work. The purpose of this study is to analyze the productivity of the construction site quality management system, which is in the early stages of implementation at construction sites. This study implemented the construction site quality management system at a road construction site and scrutinized subsequent alterations in the quality management workflow before and after the implementation. Additionally, a survey was conducted among quality control engineers to collect data on work time both before and after the introduction of the construction site quality management system. Based on the collected data, the Monte-Carlo simulation method was applied to analyze the productivity improvement effect of the construction site quality management system, and the results were presented. The results of this study can serve as foundational data for future research endeavors focused on the automation of quality management works.

Larger and more sophisticated building construction requires more input resources such as worker, materials and devices. Growing resource volume brings risks at a construction site. The industry makes an effort to protect probable incidents at the site by organizing a safety management team. conducting a safety instruction and etc, but losses especially in the construction are higher than other industries. Major reason is that the safety management program is conducted only at the step of construction work and a root cause is not eliminated. Conventionally a concerned party shifts the blame to other parties such as constructor and site workers who are direct participants in the construction site. However, the whole causes of incidents go to the all subject of the construction not only the constructor but the client, designer and others related in the construction, and especially the clients are heavily involved in general concerns of the project. Therefore, this study is defined the role of the clients in nations and domestic condition of construction safety management is investigated. And it is analyzed surveys to prevent incidents at construction sites, and suggested the role of the clients which is classified pre and post construction, and in the middle of construction, and also categorized planning and design & construction schedule especially for the pre-construction level.
