Using the CSI(Construction Safety Management Integrated Information) data, a comparative analysis was conducted by work type and construction cost according to whether the construction sites were subject to making a safety management plan or not. As a result, by type of work, the ratio of deaths in non-plan sites was high in mechanical facilities and earthworks, and the operation performance of the system was much higher in sites that were less than 5 billion won of construction cost.

Construction workers are engaged in many activities that may expose them to serious hazards, such as falling, unguarded machinery, or being struck by heavy construction equipment. Despite extensive research in building information modeling (BIM) for safety management, current approaches, detecting safety issues after design completion, may limit the opportunities to prevent predictable and potential accidents when decisions of building materials and systems are made. In this respect, this research proposes a proactive approach to detecting safety issues from the early design phase. This research aims to explore accident precursors and integrate them into BIM for tracking safety hazards during the design development process. Accident precursors can be identified from construction incident reports published by OSHA using a text mining technique. Through BIM-integrated accident precursors, construction safety hazards can be identified during the design phase. The results will contribute to supporting a successful transition from the design stage to the construction stage that considers a safe construction workplace. This will advance the body of knowledge about construction safety management by elucidating a hypothesis that safety hazards can be detected during the design phase involving decisions about materials, building elements, and equipment. In addition, the proactive approach will help the Architecture, Engineering and Construction (AEC) industry eliminate occupational safety hazards before near-miss situations appear on construction sites.

This study analyzed the smart construction safety cost included in safety management plans that are approved before construction. Specifically, it refers to the cost incurred in constructing and operating a safety management system using wireless communication and facilities. Based on the obtained statistical results, an activation policy for the inclusion of the smart construction safety cost in building safety management plans was proposed. The smart construction safety cost must be included in the safety management cost; notably, this is mandated by the Construction Technology Promotion Act. However, there are some problems with the inclusion of smart construction safety costs. To analyze the problems encountered when calculating the smart construction safety cost and including it in safety management plans, in this study, statistical analysis was performed using the data of 1,334 safety management plans received at the Construction Safety Management Integrated Information (CSI) from June to August 2021. The results show that only 50.7% of the safety management plans included the smart construction safety cost although the current law mandates 100% inclusion of these costs. Thus, it is apparent that the smart construction safety costs are only included in a low proportion of sites. In addition, the calculated smart construction safety costs were shown to have a small correlation with the construction cost; moreover, they appeared to be distributed at a constant cost level. In this context, it is believed that perfunctory cost calculations were performed at most sites since the effect of the construction cost on the smart construction safety cost was negligible. Therefore, it is necessary to improve the inclusion of smart construction safety costs by strengthening the authorization process of the approval institute of safety management plans. In addition, institutional support, such as guidelines that promote the calculation and inclusion of appropriate smart construction safety costs according to the characteristics of sites, are needed.

The scope of this study is the construction conformity assessment system according to the new paradigm of construction management To minimize the differences between domestic and international state, construction Conformity Assessment is subdivided into system certification and product certification. For the former, WASCON(Worldwide Assessment System of Construction Quality Maturity Stage) is applied. For the latter, AQUA(Advanced Quality Assessment System) was developed and adopted to model project for demonstration. Both systems are designed to enable quantified rating, integrated into PQCS(Project Quality Certification), which is an advanced project quality certification system. The construction work observing PQCS will gain quality score on its own quality certificate(Quality mark on construction itself or facilities is also available, if needed or preferred by customers). This Quality Rating System will inspire and encourage any related parties. PQCS score would let supplier/constructor recognize how much themselves are operating effectively and efficiently, offering them the opportunity of redeeming their weaknesses.

건설공사의 계약문서에는 설계도면, 공사시방서 등이 포함된다. 그러나 공사시방서의 경우 분서의 중요성만큼 활용되지 못하고 있다. 그 이유는 시발정보가 설계도면과 재료마감표등 다른 건축정보들과 관련되어 찾을 수 있게 되어있지 않아 활용도가 떨어진다. 따라서 다른 정보와 연관되어 질 수 있는 통합모델이 필요하고 이러한 통합모델을 바탕으로한 DB가 구축되어 져야 설계 및 시공, 유지관리시에 그 활용성이 증대된다. 이러한 통합모델의 구현은 부위를 사용함으로서, 설계도를 작성하고 그리고 부위 정보에 자재정보, 법규정보, 시방정보의 속성이 들어가 있다면 견적을 낼 수 있고 많은 정보를 참조할 수 있어 설계의 질이 향상될 것이다. 또한 유지관리시에도 설계정보에 법규, 자재정보, 시방정보가 들어가 있기 때문에 수선유지 및 하자보수등에 유용하게 사용된다. 설계단계에서부터 만들어진 시방정보 DB는 설계의 수정과 공사의 수정에 맞게 update 되어 져야 한다. 또한 시공현장이나 감리시에도 참고를 하기 위해서는 시방서가 web을 이용한 문서화가 되어 어디서든지 참조할 수 있는 환경이 되어 져야만 한다. 따라서 본 연구에서는 시방정보 구조화를 위한 부위분류 체계글 제시하고, 이를 바탕으로 하여 건축시방정보를 DB화하며, DB를 상호 참조할 수 있는 인터넷 환경에서의 시방정보의 검색 빛 작성이 가능하도록 하였다. 이 시스템을 활용하여 공사시방서출 작성, 참조함으로써 공사시방서의 활용의 향상이 기대되려 이를 통해 건설공사의 클레임 방지와 설계, 시공, 유지관리의 품질 향상이 기대된다. 또 발주기관, 설계용역업체, 공사현장 등의 실무에서 더욱 편리하게 정보를 활용할 수 있을 것으로 사료된다.

The existence of material price volatility in construction projects puts forward substantial risks for all parties involved. Depending on the parties involved in the project, type of contracts, and state of the market various risk management strategies are practiced by contracting parties to manage project risks related to price volatility. Unfortunately, in many cases companies fail to select an adequate approach to better manage volatilities of material prices due to the lack of a decision support system to aid in the selection of an appropriate strategy based on the project characteristics. The aim of this study is to identify critical project factors and align them to documented strategies to manage price volatility based on an extensive literature review and industry interviews. This study found Integrated Project Delivery (IPD) as the ideal strategy with respect to project duration; quantitative risk management methods with respect to the cost; and Price Adjustment Clauses (PAC) with respect to the risk allocation, as the top price volatility management strategies.
