건설 프로젝트 관리의 주요한 목표는 계획된 시간 내에, 정해진 예산으로 규정된 목표(명세 또는 품질)를 확보하는 것이다. 국내 건설 산업은 타 산업 분야에 비하여 생산성이 매우 낮은 편이다. 이는 60년대 이후 급속한 개발 정책에 따른 부작용의 하나로, 하드웨어의 급속한 성장에 비하여 이를 관리하기 위한 소프트웨어의 개발이 부족했기 때문으로 풀이할 수 있다. 이에 본 연구에서는 건설 프로젝트의 생산성을 향상시키기 위한 노력의 일환으로 계획 단계에서의 실행과 완성 단계에서의 실행을 비교하여 이를 작업일보, 감독일지 등의 진도관리 자료를 활용하여 분석하여 건설 프로젝트의 실제적인 생산성 저하 요인을 도출하였다. 따라서 본 연구 결과는 현행 국내의 건설 프로젝트에 대한 사례분석을 통하여 실제적인 생산성 저하 요인을 분석한 것인 만큼 향후 건설 관리 기술의 향상에 많은 도움을 줄 수 있을 것으로 기대된다.

This study was intended to present measures for the improvement of the apartment house landscaping supervision system by examining the adequacy of landscaping supervision, which is aimed at improving the quality of landscape plants and facilities in apartment house landscaping sites. Additionally, this study aims to identify the problems occurring in the process of the performance of landscaping supervision and to provide the evidence for legislative activities and revision of the laws currently being pushed forward for the mandatory deployment of apartment house landscaping supervision personnel. The results of the analysis showed that no landscaping supervision personnel was deployed to apartment complexes with less than 1,500 households and that the landscaping comprised 19% to 46% of the entire construction process. The civil engineering firm performed the landscaping supervision, which made it impracticable to fully focus on the construction quality in the field of landscaping. The quality control in terms of landscape plants revealed differences in quality control, depending on the competence and experience of the civil engineer supervising the personnel, where the landscaping supervision personnel was not deployed. The apartment houses landscaping supervision activity index was analyzed, and the results showed that the supervision activity index for apartment house A was 72.0, B was 70.4, and apartment houses C to G ranged from 38.7 to 46.9, which suggested that the difference in quality control, process control, and technical support affected the construction quality and occurrence of defects.The improvement of landscaping process quality control and process management will be carried out more smoothly and the rate of defects will be drastically reduced if the landscaping supervision personnel placement threshold is lowered from 1,500 households to 300 households in complexes. The results of this study are expected to be useful in promoting and re-establishing the landscaping industry based on the improvement of construction quality in the field of landscaping in connection with the construction of apartment houses.

The several smart construction technologies are being introduced to the construction industry, and among these technologies, a few companies are attempting quality control using 3D scanning and BIM. Therefore, in this study, 3D scanning and BIM were applied to cases of on-site quality inspection to confirm the applicability and utility. As a result, it was confirmed that the quality inspection using 3D scanning and BIM was shorter in time than the previously performed quality inspection and can be realized with less manpower. Therefore, it is considered that 3D scanning and BIM-enabled technologies can be applied to various items of quality inspection.

Recently, apartment housing tends to increase 3-4% every year by economic growth and development of construction technology in domestic construction industry. According to this tendency, construction enterprises are providing high-quality and various residential space, and residents also want high-quality apartment housing without any defect. Construction company make efforts to decrease construction defects in order to satisfy all the residents, and to improve company value. However, it is impossible to have no defect in construction because construction works are combination of many different complicated process. Because of the responsibility for the defect, conflicts between construction company and residents have been occurred. This study suggests defects management method that can be used from defect register phase to defect repair phase with a function of smart-device of the high penetration rate. The effectiveness use of the suggested method might save defects maintenance time and improve resident satisfaction about construction quality.

The purpose of this study was to Identification the Risk of construction method to protect and reduce of construction period. Risk management is one of the key project management process. Numerous tools are available to support the various phases of the risk management process. We present the results of a study designed to identify the tools that are most widely used and those that are associated with successful project management in general, and with effective project risk management in particular. The study is based on a questionnaire administered to a sample of project managers from construction enterprises. The response data was analyzed in order to find which tools are more likely to be used in the those organizations that report better project management performance and in those that value the contribution of risk management processes.

건설은 경제 발전과 일자리 창출에 중요한 역할을 담당하고 있다. 그러나, 건설 산업은 타 산업에 비하여 고위험 산업으로, 매년 많은 사고와 재해가 발생하고 있다. 노동부 중대산업재해감독과에 따르면 2022 년 재해조사 대상 사망사고 발생 현황 발표 결과, 건설 사고 사망자는 341 명으로, 전체 산업재해 사망사고자의 53%를 차지하고 있다. 최근 사회 변화와 다양한 경기 변동, 물가 상승에 따라 건설 공사 비용 절감을 위한 안정성 결여, 시공 품질 관리의 어려움, 근로자 안전 의식 부족 등의 문제가 심화되고 있다. 이에 따라, 건설 현장의 근본적인 안전문화의 정착과 함께, 첨단 ICT 기술을 활용한 지능형 건설 안전관리 시스템의 구축이 필요한다. 그리고, 건설안전관리를 위한 스마트 건설 안전관리통합관제시스템(SCMS)의 기능과 적용 범위를 더욱 확대함으로써 건설 현장의 안전사고 예방을 개선할 수 있을 것으로 기대된다. 이를 위해 지속적인 다양한 연구와 데이터 수집과 분석 등 기술적인 연구와 함께 법과 제도에 대한 개선 논의가 필요하다.

Recently, client requirements concept is an important issue related to many effects of firms. Especially, if we think that apartment is given a great deal of national construction industry, it is requested that we should try to improve apartment quality with various methods of client requirements survey and reflecting those on apartment project. The technique searching and applying client requirements to apartment project is requested for that and ROQ(Return On Quality) process connected to QFD(Quality Function Deployment) is a technique which is used in manufacturing industry and help to make money by rising client satisfaction with searching clients requirements, and applying this to quality improvement program. In this study apartment quality management development is suggested through using ROQ process. For this customer interview research and FGI(Focus Group Interview) was carried out and clients requirement was analyzed with this. Then quality improvement program applicable to developing a new apartment product was established with specialist monitoring. A new apartment quality management development plan is prosed with this process.

With the recent rising project complexities and competitive environments in the construction projects, a risk management is recognized as more important management tool than the others. However, as most risk management techniques applied to the construction projects are centered around their initial phases and risk analyses, they are not developed into general project management technique such as time management, cost management and quality management, etc., that are usually applied in the process of construction. Thus, this paper proposes a response process to construction project risks based on the risk threshold and its calculation methodology applying a concept of VaR to establish risk management as general management technique in the construction projects.

In accordance with Korean structural foundation design standards, dynamic or static load tests are mandated for 1 to 3% of total piles. The construction quality of the remaining 97% to 99% of piles is determined through penetration measurements. This study aims to enhance the quality control of the majority of piles by adopting a pile driving formula that considers both penetration and hammer energy. The current challenge lies in adapting existing overseas driving formulas to the domestic site conditions, characterized by shallow weathered or soft rocks, and the prevalent use of pre-bored piles. To address this, the Modified Gates formula was refined using domestic dynamic load data, thereby improving its applicability to pile management. Despite employing fewer variables, the proposed formula demonstrates a comparable accuracy to dynamic loading tests in predicting the bearing capacity of pre-bored piles. Consequently, this formula holds promise for practical use in future pile quality management.
