The construction industry has the most safety accidents among domestic industries. Special care must be taken because disasters in the construction industry lead to social problems caused by huge property losses and casualties. As a result of this, there is a growing awareness of disasters occurring in the construction industry, and government departments are tightening regulations on safety management. In particular, the OSHA(Occupational Safety and Health Agency) focuses on the expansion of protection targets and the clarification of responsibility in the full amendment OSHA. As a result, a study that focuses on safety management by client's responsibility is needed. In this study, the project performance capability assessment of construction project management contractors, which is being carried out with uniform assessment criteria without considering the characteristics of the construction project, is considered and all the amendments to the OSHA are considered, and the factors were derived for improvement measures.

FCP requires different curvatures and shapes according to the method of division, and it is necessary to manufacture a formwork accordingly. FCP production equipment consists of CNC equipment and side shape control equipment. This can be implemented in various shapes of upper, lower, and side surfaces. In the side shape control equipment, it is implemented as a variable side formwork. Among the required performance of the variable side formwork, there is stiffness against side pressure, which needs to be verified. Therefore, in this study, the FCP fabrication experiment is conducted with the developed variable side formwork. By analyzing the error in the shape of the fabricated FCP, the lateral pressure resistance capability of the side form is measured and verified.

The construction industry is highly dependent on human resources and changes the degree of completion of construction work depending on the level of performance of engineers. As women's social advancement has recently expanded, the construction industry is also experiencing a large influx. Therefore, it can be seen that not only male engineers' ability to carry out work but also female engineers' ability to carry out work is important. Therefore, this study investigated the actual work conditions and work performance capabilities of female engineers and presented them as basic data for the construction of work capability improvement measures.

본 연구의 목적은 건축프로젝트에 있어서 디자인분야 개선요소의 특성을 파악하는데 있다. 기존 연구에서 디자인요소 중 열여덟 개의 개선요소들이 정리되었으며 이러한 개선요소들을 중심으로 건설관계자들의 설문조사를 통하여 주요도를 결정하였다. 연구결과는 각 파트별 협조가 가장 큰 개선요소로서 나타났으며 경영개선의 리더십, 팀워크, 시공능력 순으로 나타났다. 또한 각 그룹별 공통적인 개선요소로서 설계사무소와 시공자와의 원활한 의사소통이 상위개선요소에 지적되었다. 디자인에 있어서 초기 공사와 완공 후 유지관리를 반영한 시공성에 중점을 둔 설계에 대한 관심도 크게 나타났다.

Although work-efficiency of construction machinery is a critical factor for estimating its workable-quantity per unit time, the coefficient figure table presented in the Poom-Sam that is used for Construction Cost Estimation of public sectors in Korea is very subjective for practical usage. In order to suggest objective work-coefficient table for a Tub Grinder, domestic and overseas documentary records were investigated and on-going construction sites were also visited. The research found that the table can be revised by means of detailing down by several factors. The research will be the foundation for applying the rapid development of Construction Equipment and technology to the appropriate cost estimations and the ground work of related studies.

As buildings are built higher and their service life made longer, face brick walls are also required to be constructed in an easy and systematic manner, and to ensure their satisfying structural performance, inspectingly, against lateral load. Therefore this study aims to investigate the structural performance of face brick walls constructed by a new method using screwed stainless steel connectors and provide fundamental experiment data for field application of this method. The results of this study indicated that the face brick wall tied with screw connectors had better shear capacity against rocking motion than that of the wall constructed with ordinary tie bars when their tie spacing was the same. Based on the good performance of the wall tied with the screw connector, it is also expected that the spiral anchors developed in this study can possibly applied to high-rise by adjusting the spacing of the anchors considering the difference of dimensions.

The rising number of accidents during building demolition work has significantly heightened interest in this field. This study undertakes a comprehensive analysis of the essential capabilities required for building demolition experts, drawing on both domestic and international examples. This includes an examination of training courses for building demolition inspectors and the competencies mandated for structural demolition roles as per Korea's National Competency Standards(NCS). Furthermore, the study reviews the qualification tests and training programs for building demolition professionals in the United States, Japan, and England. The research concludes that the expertise needed for demolition construction professionals should be categorized into seven key domains: legal, structural, safety, planning, operational, constructional, and environmental aspects. These competencies are further divided across three professional tiers: technician, engineer, and manager.

An unstiffened top and seat angle connection is a type of partially restrained connection that is suitable for low- and medium-rise steel buildings. The plastic moment resisting capacity of such connection is needed in practical design, in addition to the accurate prediction of the initial rotational stiffness. Therefore, most of the studies conducted for the mentioned connections were performed to predict the initial stiffness and the plastic moment resisting capacity with varying geometric properties. The main parameters of such experimental tests were the thickness and high-strength bolt gauge distance of AISC LRFD-type A top and seat angle connections. Based on the test results, the analytical model was also proposed in this study. The applicability of the proposed model was verified by comparing the test results from this study with those of other studies.
