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.

본 연구는 플랜트 시공 현장의 안전성 확보를 위한 플랜트 시공단계의 주요 위험요인 분류 및 위험요인별 중요도 분석을 목적으로 수행되었다. 플랜트 산업은 지속적인 호황과 증가로 해외 플랜트 수주 실적이 2014년에는 전체 수주금액의 61% 증가한 실적을 보였듯이 플랜트 산업은 시공 단계의 위험요인, 안전관리 대상 인식 및 요인별 중요도 등으로 다양한 사고 예방 및 안전관리 개발과 도입이 필요한 실정이다. 이를 위해 플랜트 시공단계의 재해현황 자료 수집 및 국내 플랜트 시공관련 전문가를 대상으로 1차 조사 분석을 수행하여 플랜트 시공단계의 위험요인을 4M의 4가지 관리요인으로 분류하였다. 이후 AHP 기법을 적용하기 위해 국내 플랜트 시공 및 안전관련 전문가를 대상으로 2차 조사 분석을 수행하였다. 2차 분석결과를 바탕으로 위험요인별 중요도 및 순위를 분석하여 제시하였다. 본 연구는 플랜트 시공단계의 주요 위험요인을 사전에 파악하여 인식하고 이를 예방하기 위한 기초 자료로써 활용하고자 한다.

Risks and uncertainty are unavoidable problems in management of projects. Therefore, project managers should not only prevent risks, but also have to respond and manage them. Risk management has become a critical interest subject in the construction industry for both practitioners and researchers. This paper presents critical risk factors of office building projects in the construction phase in Ho Chi Minh City, Vietnam. Data was collected through a questionnaire survey based on the likelihood and consequence level of risk factors. These factors fell into five groups: (i) financial risk factors; (ii) management risk factors; (iii) schedule risk factors; (iv) construction risk factors; and (v) environment risk factors. The research results showed that critical factors affecting office building projects are natural (i.e., prolonged rain, storms, climate effects) and human-made issues (i.e., soil instability, safety behaviors, owner's design change) and the schedule-related risk factors contributed to the most significant risks for office buildings projects in the construction phase in Ho Chi Minh City. They give construction management and project management practitioners a new perspective on risks and risk management of office buildings projects in Ho Chi Minh City and are proactive in the awareness, response, and management of risk factors comprehensively.

군부대 이전사업의 소요 증가에 따라 활용되어온 기부대양여방식이 사업시행에 있어 관련제도와 법규, 사업시행자와 군 부대간의 상호이해의 부족 등의 이유로 대다수의 사업이 지연되고 있으며 개선이 요구되고 있는 상황이다. 이에 본 연구에서는 이전사업 추진 단계별 잠재적 리크스 요인 즉, 사업특성과 시행에 제약이 되는 문제를 확인하고 우선순위를 도출하여 위험요인을 분석하고자 하였다. 도출된 위험요인들 중 인허가 및 설계 단계에서의 시설기준을 초과한 요구, 사업승인 단계의 부대이전반대, 시공 및 준공단계의 시공 중 설계변경, 재산 처리단계의 기부/양여 재산에 대한 이견, 합의각서 체결단계의 시설기준의 부재가 우선적인 리스크 관리 고려대상으로 분석되었다. 본 연구는 리스크 관리의 우선순위를 제공함으로써 사업관리자가 더욱 효울적으로 사업을 추진할 있는 가이드라인을 제공할 수 있을 것으로 기대된다.

International construction projects typically manifest difficult, complex, and varied types of risk exposures; because of this, there is a need for accurate evaluation of risk-integrated performances during the timeframe of project execution. Given the financial crisis currently affecting the world economy recession, risk management has become a more crucial part for the success of international project management. However, the majority of risk management approaches, particularly for overseas projects, are focused primarily on simple forms of checklists, formalization of risk variables affecting project performance for a specific phase, or more complicated computational methods that restricting practical utilization in real-world projects; moreover, these methods lack the conceptual basis to broadly visualize the level of risk over all phases of a project. This study suggests an efficient, yet simple risk-integrated total index to successfully assess the risk levels of overseas construction projects. To this end, this paper first investigates the life cycles and key processes of decision-making for a given project and then derives formulas to represent the total risk index (TRI) along the key decision-making processes. In addition, the study examines the relationships between TRI and performance levels based on the analysis of 126 real-world project samples. Validations using the proposed TRI showed a high correlation to project performance, signifying the usefulness of the proposed approach for construction firms when investigating the level of risks and key areas for management focus.

국내 건설시장 개방과 건설경기 침체에 따른 과당경쟁, 급속한 정보기술의 발달과 시시각각 변화하는 동태적인 사회 환경 등이 건설 환경을 급속하게 변화시키고 있으며, 이에 따라 건설사업에서의 리스크 또한 현저하게 증가하고 있다. 또한, 이러한 리스크를 다루는 리스크 관리가 사업의 성패와 부가가치 결정에 커다란 영향을 주고 있어 건설사업에서의 리스크 관리가 철실히 필요한 시점이다. 본 연구에서는 국내개발사업 사전기획단계에서의 제한된 정보를 이용하여 효과적으로 리스크를 관리 할 수 있도록 주요 리스크 인자 식별 및 분류를 통해 통계적 기법으로 중요도를 분석하고, 기획단계별 주요 리스크 인자를 분류하여 기존의 경험에 의존한 직관적이고 주관적인 리스크 관리를 보다 객관적으로 수행할 수 있도록 하는 기초를 마련하였다.

During the administration of a construction project, various types of participants are engaged in the project. From the design phase to the maintenance phase, these participants may confront many risks. To avoid these risks, participants should utilize an insurance company or a bond company. The types of risks and liability that a construction manager may face are listed in the construction law or contract. But there are some arguments related to risk transferring and the content of risks. For this reason, construction managers must carefully consider any possible risks in the contract and the construction law. Therefore, for construction managers to deal with risks appropriately, the introduction of a legal requirement to carry professional liability insurance, a defined compensation range for damages, a method of guarantee in the event of defects, a defined compensation claim period for damage, and a method of damage claim were suggested in this study.

In building project, client needs to decide many things, and clients cooperate with architects, supervisors, general contractors and other consultants. Especially in construction phase, clients often make a decision. However, client's decision-making in construction phase often makes some kinds of risk. This paper aims to clarify the reality of client's decision-making in construction phase. First, client's decision-making is defined by laws and standards. Second, the questionnaire revealed the current status of client's decision-making in 4 works. Third, Fishbone diagram shows the factors of client's decision-making in four works. Finally, it was modeled how client's decision-making in construction phase affects the post-process of 4 works.

정부의 건설산업 혁신방안 중 기술혁신을 위한 주요과제의 하나인 시공책임형 CM 사업의 제도화를 위해 2017년부터 현재까지 시범사업이 활발하게 이루어지고 있지만, 시공이전단계 사업관리의 핵심인 GMP를 결정하는데 핵심도구인 설계VE와 관련한 기준 및 프로세스는 아직 정립되지 않은 실정이다. 이에 시공책임형 CM과 설계VE 관련 연구 및 운영실태, 그리고 사업참여자 인식조사를 통해 기존 설계VE 프로세스에 대한 문제점을 도출하고, 시공책임형 CM 사업에 적합한 설계VE 프로세스를 제안하고자 하였다. Schedule, Cycle, Process 등 3가지 측면에서 적용안을 제안하였으며 심층면접조사(FGI)를 통해 적절성과 적용성을 검증하였다. 본 연구의 결과는 향후 이루어질 발주기준 정립 및 법제화에 대한 기초자료로 활용될 수 있을 것으로 기대한다.

The construction work to establish a safety management plan should be carried out Design for Safety(DFS) task by the designers from May 2016 according to the amendment of the Construction Technology Promotion Act. However, designers lack experience in construction work and lack of information on safety accidents, so it is not easy to predict a disaster that may occur during the construction phase. Therefore, the purpose of this study is to provide information about disasters that can occur in each construction work in order to enable designers to efficiently perform DFS task in the design phase. In this study, the construction work was classified by work unit and the disaster risk assessment was conducted using the Failure Mode and Effect Analysis technique. The disaster information by work unit analyzed in this study can be used to provide designers with an alternative to prevent disasters at the design stage. Disaster information by work unit of apartment construction can be used by designers to prepare an alternative for disaster prevention at the design stage.
