플랜트 시장이 성장함에 따라 발주자의 공기단축을 위한 품질, 기술에 대한 요구가 커져가고 있다. 다른 건설 프로젝트에 비하여 플랜트 프로젝트는 방대한 규모와 복잡한 공정으로 인하여 프로젝트 참여자간의 의사소통, 작업의 중복, 오류, 누락, 재시공 등의 문제가 발생하고 있다. 이를 방지하기 위해서는 참여자간 현장에서 부재, 장비, 공사에 관한 정보공유가 실시간으로 이루어져야 한다. 본 연구에서는 효율적인 배관공사관리를 위한 모바일 기반의 NFC, AR기술을 활용하여 프로세스 개선 및 시스템 구축하였다. 본 연구에서 개발된 프로세스 및 시스템은 현장에서 실시간적인 정보공유 및 전달이 이루어질 수 있는 환경 구축을 통하여 현장에서 보다 효율적인 공사관리가 이루어질 것으로 기대된다.

Constructionarium Ltd is a not-for-profit organisation which delivers a residential, experiential, immersive learning opportunity to university students from across the built environment education sector. Since 2002, the Constructionarium education model has been available to students in engineering, construction management and architecture at a purpose built, 19-acre multi-disciplinary training facility in Bircham Newton, England simulating real site life and reflecting site processes, practices and health and safety requirements. The unique approach of Constructionarium puts experiential learning and sustainability at the heart of everything. In a week, students develop a practical understanding of the construction process, develop transferable skills, build a team and are exposed to the latest in sustainable technologies. Experiential learning is what differentiates a Constructionarium project from regular field trips or site visits. At Constructionarium the focus is on learning by participation rather than learning through theory or watching a demonstration. The projects cannot be replicated in a classroom or on campus. Using the hands-on construction of scaled down versions of iconic structures from around the world, students learn that it requires the involvement of the whole construction team to successfully complete their project. Skills such as communication, planning, budgeting, time management and decision making are woven into a week-long interrelationship with industry professionals, academic mentors and trades workers. Working together to enhance transferable skills brings the educational environment into the reality of completing an actual construction project handled by the students. Constructionarium has used this transformational learning model to educate thousands of students from all over the United Kingdom, Europe and Asia. Texas A&M University in the United States has sent multiple teams of students from its Department of Construction Science every operational year since 2016.

우리나라 건설공사의 품질관리체계는 관련법에 근거한 규정의 조합과 시공자가 구축한 ISO/KS A 9001에 의한 품질경영 시스템의 운용에 의한 방법의 혼합형이다. 이 두 가지의 품질확보체계는 상호 보완적이며 통합된 체계로 운영되어야 하나, 시공자의 품질경영시스템을 활용하지 못하고 법에서 정한 기준과 방법, 절차 등의 규정에 따라 모든 공사에 있어서 일상화된 품질관리업무가 수행되고 있다. 이러한 현상은 ISO규격이 도입된 이래 지난 10여 년간 계속된 문제점으로 개선이 요구되고 있다. 품질관리의 철저를 목표로 고객 만족을 위한 예방적 품질관리사고를 정착하는 일은 건설산업의 당면과제이다. 이에 본 논문에서는 건설현장 의 실무자를 대상으로 품질관리 관련 의식에 관한 설문조사를 실시하였으며 그 결과를 토대로 건설공사 품질관리 체계의 운용에 대한 만족도를 정리하고, 나아가 향후의 개선방안에 대한 논점을 제시하고자 한다.

초고층$\cdot$대형 현장은 일반 현장관리 방법과는 달리 경험에 의한 의사결정에는 한계가 있다. 특히 도심지 고층 공사의 경우 대지의 여유 공간이 협소하여, 자재적치와 수평 동선을 위한 공간의 확보가 용이하지 않다. 이러한 초대형 프로젝트를 수행하기 위해서는 기존 경험에 의존하는 양중 및 조달 관리의 한계성을 인식하고 새로운 양중 및 조달 관리 방법의 모색이 필요하게 되었다. 따라서 JIT의 개념을 도입하는 것이 필수적이라 하겠다 현장 내 즉, 반입 이후의 단계는 물리적인 자재의 흐름보다는 정보의 흐름과 의사소통이 중요시되는 단계로 본 연구에서는 현장 내 물류흐름의 문제점을 분석하여, 자재별 속성을 고려한 양중계획수립, 작업일정과 양중일정의 통합관리, 자재의 위치현황 및 작업의 설치현황 가시화를 통한 정보의 공유, 계획대비 실적의 평가의 부분을 시스템개발 방향으로 설정하여. 커뮤니케이션 도구로서의 역할과 계획 대비 실적 평가를 통한 계획의 신뢰도 확보 등을 주요 기능으로 하는 양중관리시스템을 개발하였다.

Construction accidents occur reiteratively in similar fashions. There have been several attempts to develop a safety program for preventing construction accidents on sites. It will be very effective to use previous accident cases for establishing proper safety plan and managing safety process. This research develops a case-based construction safety management system which enables construction managers or safety managers to prevent potential accidents during the construction process. The case-oriented approach is performed through the representation of previous accident cases in accordant with the similarity to the conditions of current site. It uses a case-based reasoning which is one of the reasoning methods of an expert system. A prototype system for the reasoning model was implemented using one of the case based system development tools. The system was applied to a real construction site to verify its capability and validity. It was founded that the causes of accidents were successfully removed, so the proposed model proved to be reasonable. Additional research is needed to resolve the technical problem how to adapt the countermeasures for accident prevention provided by the reasoning model.

Appropriate management of the finish works in construction project is one of most important activities that must be conducted considering the total duration of the project. Masonry work is a fundamental process that is performed in the preliminary steps of finish works. However, it has been investigated that the analysis of delay factors affecting masonry work has been neglected in the domestic construction site. Therefore, this study deducts delay factors affecting masonry work by literature review and survey on site engineers and labors. This study has been conducted as a preliminary step of developing a construction project interference management system which is expected to suggest objective information for the decision making in construction sites.

This study presents the problems of data imbalance, varying difficulties across target objects, and small objects in construction object segmentation for far-field monitoring and utilize compound loss functions to address it. Construction site scenes of assembling scaffolds were analyzed to test the effectiveness of compound loss functions for five construction object classes---workers, hardhats, harnesses, straps, hooks. The challenging problem was mitigated by employing a focal and Jaccard loss terms in the original loss function of LinkNet segmentation model. The findings indicates the importance of the loss function design for model performance on construction site scenes for far-field monitoring.

Recently, the Malaysian government had been developing new technologies to the construction industry and one of them is the Industrialised Building System (IBS). The government urged that IBS is 100% utilized in all construction projects. It is believed that the application of IBS helps in reducing construction duration and cost, solving the problems of overflow of foreign workers in the site and improving performance and appearance of a structure. However, there are some parties like the contractor who feel reluctant to utilize this system because there are risks. They worry that their trades will be affected as IBS construct a structure using components which are manufactured in a factory and assemble on site. Therefore, this research is to find out whether IBS benefits the country's economy by focusing on the business created by investing in IBS. A comprehensive supply chain for IBS will be developed to compare with the traditional construction supply chain as to determine businesses or trades created and eliminated. This paper is looking at the theoretical framework about business opportunities due to the Government policy on embarking IBS.

Unlike price calculation by cost accounting, which categorizes costs into material costs, labor costs, and miscellaneous expenses to determine the construction budget price, construction cost calculation based on Construction Standard Unit Prices utilizes unit prices extracted from market prices of items from projects already completed to estimate costs of similar construction projects. Although unit price information is collected through construction site surveys to revise these construction standard unit prices every year, but due to the limitations of the site survey method, it is difficult to quickly implement the rapid changes in the construction methods and market prices. As such, an important issue that arose was the identification of work items whose prices need urgent revision. This study conducted research on factors that need to be considered when developing online survey system for monitoring construction site market prices. This study is expected to enhance convenience for users, and provide an efficient data collection and management system for administrators.
