Safety accidents, which are called industrial accidents in construction work, are often caused by unstable physical and personal conditions combined during preparation and execution of work. It is difficult to manage all the construction works, but especially in the field of apartment construction work, complex and many kinds of works are being carried out at the same time. In the current construction, safety regulations such as safety management guidelines are generally well maintained, but the execution of manpower resources that can fulfill them is limited, and it is difficult to reduce the accident rate and loss cost. Therefore, in this study, it is a reality that most of the types of construction work are under contruction by subcontracting contract, so they are limit by methods of manual maintenance and safety education. Currently, the subcontractor is also allowed to perform safety management through the composition of the safety management review body, but it is operated formally. So alternatives to this were studied. As a result, safety accidents occur in the subcontractor's worker due to vertical integration, which is characteristic of the construction industry, together to the contractor, the safety management system is based on a safety construction system in which a worker who has a certain qualification condition such as career experience of the work type, work understanding of the work type, and management experience of the work type among the subcontractor, when we manage based on mutual personality which is the personality of interpersonal relationship that can communicate with each other by work type, process and grouping, it is concluded that effective and practical safety management can be achieved to reduce the accident rate and loss cost.

The objective of this study is, first of all, to investigate the positive and the negative interaction between the work and family lives of married company employees. Secondly, it is to investigate the variables affecting this matter. The conclusion drawn by the result acquired through process is as follows. First, married company employees feel positive more than negative because of the influence that their families have on their work. Secondly, male employees feel more of the positive influence that family has on their work more than the female employees do. Thirdly, with respect to the type of business, self-employed individuals and specialized managers seemed to have negative influences on the interaction between work and family. Fourthly, it was found that the managerial ability of the individual is a variable that affects both directions. Fifthly, it was observed that variables related to family affect the interaction between work and family in the positive direction.

This study aims to systematically identify direct and indirect factors that influence labor productivity and to build a model that mathematically quantifies them so as to efficiently manage and increase labor productivity in the construction work. This study was performed based on the productivity model for workers in reinforced concrete construction projects, because it aims to establish a general construction labor productivity model that reflects many factors that influence labor productivity. Using statistical analysis, we found that the components that significantly influence productivity were the worker component, the work characteristic component, the work technique component, the work management component, the equipment & materials component, and the work guide component, while the work delay components did not significantly influence productivity. In addition, a priority analysis was performed based on the components that showed statistically significant effects. The results of the analysis indicated that the influence of work management component and the work technique component is more than that of the worker component and the work characteristic component. The construction labor productivity model that was formulated in this study could be used for the determining the standard productivity during the initial planning stage, so the best strategy for increasing labor productivity could be formulated.

Since entering the 21st century, the construction industry has developed faster and faster, and more and more technologies have been applied in the construction industry. BIM technology (Building Information Modeling) was born in this environment. The application of BIM technology can greatly improve the efficiency of cost management and help achieve the goal of cost management. But through BIM to realize project cost management, there is still no good solution. In order to solve this problem, this paper puts forward the concept of WBS structure applied to construction projects by studying the BoQ (Bill of Quantities) list based on BIM, and proposes the numbering method of the structure. The WBS (Work Breakdown Structure) structure proposed in this paper divides more than 5000 cost objects into 133 projects according to the type of work and project schedule. This structure helps to realize the application of BIM in project cost management. Although this article has studied more than 5000 data of three projects, it does not think that it can cover all cost objects in the existing construction industry. The purpose of this article is to propose a solution for cost and Process Control using BIM-based BoQ data.

기술문명의 지속적인 발전은 이루어 경제성장과 물질적 풍요로움을 주었으나, 환경에 대한 고려를 통한 발전이 무엇보다 요구되는 시기가 되었다. 건설 분야의 경우도 예외가 아니다. 따라서 최근 건설 산업에서는 친환경 공법을 적용하며, 폐기물을 줄이는 등 환경에 대한 관심이 어느 때보다 높아졌다. 국내의 노후 공동주택이 점차 증가함에 따라 성능개선방안으로 재건축 및 리모델링이 수행되고 있다. 하지만 재건축이 가지는 비용적, 환경적 측면에서의 문제로 인해 리모델링의 수행이 대안으로 인식되고 있다. 리모델링 공사는 특성상 철거공사가 선행 된다. 철거공사는 필연적으로 건설폐기물 발생이 수반된다. 따라서 환경적 측면을 고려한 폐기물 처리가 중요하며, 이를 위해서 선별 분리를 위한 친환경 리모델링 철거공사가 수행되어야 한다. 그러나 친환경 리모델링 철거공사는 주로 기계를 사용하여 수행하는 기존 방식에 반하여 인력이 중심이 되므로 생산성 측면에서 효율성이 낮다. 리모델링 공사는 특성상 철거공사 후 후행공사가 진행되기 때문에 철거공사의 작업효율성 확보가 중요하다. 따라서 본 논문은 친환경 리모델링 철거공사의 세부공정을 작업효율성이 포함된 공정으로 재구성하고자 하였다. 이를 위해서 노후 공동주택을 선정하여 실제 사례연구를 실시하였다. 친환경 철거공사 사례적용을 분석하여 본 사례에 적합한 TACT공정을 개발하였고 이를 고층형 아파트에 적용시키기 위해 공정 Simulation을 실시하여 친환경 리모델링 최적 TACT공정을 제안하였다.

Despite the significance of ports as critical economic infrastructure, the berth facilities usually deteriorate due to heavy loading, unloading, aging, environmental weather conditions, marine growths, and lack of efficient maintenance management. Marine berths require proactive maintenance management to limit deterioration and defects as no berth facility is maintenance-free. Thus, delay in carrying out maintenance work for the marine berths can be devastating to the operational process involving ship entry, loading, and unloading operations. The aim of this research is to coordinate both operations work, and maintenance works that take place inside the berth of a local industrial port in Saudi Arabia, by developing a novel framework that integrates both works without affecting the efficiency and functionality of the berth. The study focused on defining the operational process of the port and identifying the elements with direct and indirect effects. In addition to determining the priority for the entry of ships inside the berth, it also identified the factors involved in designing a framework that included maintenance work as a component of the monthly berth occupancy schedule. By applying a mathematical model, a framework was established, which includes all the important elements of the process. As a result of the mathematical method formulation process, a database was designed that organizes and coordinates the operations of all berths within the port. This creates time to carry out the required maintenance work monthly as well as ease of coordination with the contractors responsible for the implementation of those works.
