In the era of the 4th Industrial Revolution, smart technology being considered to improve productivity breakthroughs is in the spotlight as a means to replace traditional construction technology in the construction industry. However, various problems are occurring in construction sites using smart technology and causing negative impacts on construction projects. Therefore, the objective of this study is to identify risk factors that occur when smart technologies are used in construction projects. To achieve this purpose, this study investigated the difficulties at construction projects using smart technology, and risk factors were derived based on site surveys and literature. The risk factors were measured by experts, and then a total of 19 risk factors was derived by exploratory factor analysis. As a result, risks were classified as 5 factors, the institutional factor is the most difficult response, and the government needs anticipative system improvement and a long-term plan. The research findings provide practical implications for construction experts trying to apply smart technology in construction sites and construction policy-makers to revitalize smart technology.

Recently, Korea has achieved accumulated total value of orders of six hundred billion dollars in international construction market, and it is facing a new turning point by entering the overseas construction market. However, according to the statistics on the current internal construction market, the accumulated value of orders has been mainly obtained by plant projects in the Middle-East area. To improve international competitiveness of Korean construction industry, it is required to expand and diversify the target areas and construction business sectors. To expand markets, each construction firm should establish the expansion strategy and assess the capability which includes the strength and weakness of their firm. Therefore, this research aims to evaluate the capability of the Korean construction firms for overseas expansion. Through the research, Korean construction industry is expected to strengthen competitiveness toward the overseas markets. Furthermore, this research contributes to expanding and diversifying markets for domestic construction firms.

본 연구에서는 국토교통부의 지방청 조직의 재설계를 통해 건설사업관리를 활성화하기 위한 방안을 제시하고 있다. 재설계 방안은 지방청 현황분석, 현업 요구사항 분석, 국 내외 선진사례분석을 통해 수립된 조직 통합 및 광역화, 사업관리 조직화, 지식관리 조직화라는 3대 개선방향을 바탕으로 도출되었다. 이후 조직 재설계방안을 구현하기 위해 16개의 추진과제를 도출하였으며, 이들 과제에 대한 중요도, 실현가능성 및 선 후행관계를 바탕으로 추진일정계획을 수립하였다. 수립된 추진일정계획을 바탕으로 도출된 추진과제를 성공적으로 수행한다면, 국토교통부 지방청 조직의 건설사업관리가 보다 활성화 될 수 있을 것이라 기대한다. 궁극적으로는 시설 운영 및 유지보수관리로 대변되는 비핵심역량 영역을 외부에 위탁하고, 지방청 역량을 신규 SOC 건설에 대한 사업관리에 집중함으로써 비용절감 및 대국민 서비스향상을 이룰 수 있을 것이라 기대한다.

건축프로젝트의 성과향상을 위해 현장관리자들이 조직에 최선을 다할 수 있도록 효과적으로 관리하는 것이 중요하다. 또한, 현장조직은 끊임없이 의사결정을 하므로 조직에서 의사결정이 적절하게 이루어지는지가 성과에 많은 영향을 미친다. 따라서 본 연구에서는 현장조직의 성과향상을 위해 현장관리자의 의사결정 참여와 조직몰입의 관계를 파악하는 것이 목적이다. 연구 결과 현장관리자들은 의사결정을 할 때 사람 중심보다는 업무 중심으로 하는 성향이 높은 것을 알 수 있었다. 또한, 의사결정 유형에 따라 정서적 몰입에 차이가 있으며, 의사결정 참여도와 조직몰입 간에 약한 상관관계가 있는 것을 알 수 있었다. 본 연구는 현장조직의 직무수행관리 능력을 높이는 데 도움을 줄 수 있을 것이다.

In spite of the socio-economic benefits of the construction industry, it accounts for many deaths, injuries and illnesses in many countries. In developing countries like Vietnam, the situation is even worse. Health and safety (H&S) management plays a crucial role in the efforts to improve H&S performance as it contributes to mitigating the risks of occupational injuries and illnesses. However, within the wider H&S literature in Vietnam, there is no insight into the current state of affairs of H&S management, particularly in terms of the management practices that need attention in order to improve H&S management across the construction sector. This study therefore presents the findings of an inquiry into the H&S management practices of contractors in Vietnam. The study employed a questionnaire survey which yielded 58 responses from contractors, particularly those operating in Southern Vietnam. Some commonly implemented H&S management practices by the contractors are: provision of personal protective equipment (94%), allocation of H&S supervisor on site (90%), and displaying of company H&S policy on construction sites, company website, and head/branch offices (86%). Some of the less implemented practices are: networking/engaging with other companies/institutions (e.g. government offices) about H&S issues (39%), rewarding workers for safe work behaviour (39%), reviewing and updating H&S plans (48%), and displaying regulatory H&S posters on site (45%). The findings have provided some insight into the current state of affairs of the H&S management practices of contractors in Southern Vietnam and could thus inform efforts by industry stakeholders to improve the aspects of H&S management that are lagging.

The purpose of this study is to improve a general Top-Down construction process for superstructure construction period reduction. In a general Top-Down construction sequence, the ground floor slab is set up first. Subsequently, 1st basement level construction including core walls is constructed. Initiation of the ground level superstructure gets waited until then. In this study, removable deck plate installation on the bottom of the core walls of ground level is preceding the concrete casting, therefore, ground level superstructure construction is able to get started earlier. Up to first typical floor concrete casting, total of seventy-two working(calendar) days will be resulted in a reduction from the total construction periods.

Building Information Modeling (BIM) is being widely spread in AEC industry worldwide and also in South Korea. Although the creation of digital model is better to be started at design stage, it can also improve the productivity of construction by simulating the actual construction process and environment. This paper presents application of BIM-based simulations related with design changes to transfer floors in 58-storey reinforced concrete office building. Transfer floor is not only a structurally important part of the building but also a challenging part of the actual construction in terms of sequence and period due to the complexity of the work. Preconstruction of rebar, mechanical, and plumbing is performed to review the construction drawings and to perform clash detection. Each item of application is evaluated for its effectiveness on actual construction and for the development potential.
