PURPOSES : This paper presents a foundational study aimed at strengthening the competitiveness of future overseas construction engineering projects, efficiently guiding investment decisions for the government or private sectors and establishing policy suggestions for areas that need to be supplemented and linked. METHODS : The data envelopment analysis (DEA) model was used to measure the operational efficiency for individual types of work. The DEA model for measuring efficiency uses the representative Charnes, Cooper, and Rhode (CCR) and Banker, Charnes, and Cooper (BCC) models. RESULTS : By using statistics of overseas construction projects and conducting DEA, it was revealed that construction management was most needed in the energy facility sector of overseas construction projects. CONCLUSIONS : Although the capabilities of our country's companies are excellent, it was evident that the energy and industrial facilities sectors, which need to be supplemented to enhance their competitiveness, require policy support that incorporates construction management (CM). Consequently, it was confirmed that the construction management sector needs investment that should continue to be activated in the future. Additional research is needed that considers variables and environments related to overseas construction projects’ on-site conditions. To this end, the government should continue to promote research and government investment linked to CM to make progress in overseas construction sectors.

As the complexity and uncertainty of international construction projects increase, the importance of risk management capabilities in the construction industry has become more pronounced. Accordingly, Enterprise Risk Management (ERM) has become a widely adopted approach among organizations as a new way for more effective risk management. Despite its growing application, research related to ERM is still in its infancy, and most of the existing studies have been limited to financial industries. Therefore, this study aims to empirically examine the influence of ERM’s core elements on project risk management (PRM) and project performance within construction firms. Our findings indicate that the key ERM components—organization, policy, and culture—significantly enhance PRM processes, underscoring their critical role and importance. Additionally, effective PRM positively affects project outcomes, highlighting its significance for construction companies engaged in international projects. While ERM does not directly impact project performance, it indirectly improves outcomes through enhanced PRM capabilities. It suggests that ERM will contribute to the firm’s performance by improving the firm’s PRM capability through policies and a risk-focused culture corresponding to the adopted ERM organization and system..

건설공사의 분쟁에는 다양한 원인이 있지만, 주된 원인으로 지목되는 것 중 하 나가 공사 과정에서 발생하는 설계변경에 따른 공사비용 증가로 인한 시공사 의 추가공사비 청구의 증가이다. 건설현장에서 발생하는 설계변경은 발생 원 인이 다양하여, 계약 당시에 이를 예측하기란 상당히 어렵다. 이러한 예측의 어려움은 건설산업 전반의 특징이기도 하며, 이 특징이 다양한 분쟁의 형태로 나타나기 쉽다. 건설산업은 다른 산업에 비해서 하나의 목적물이 생산되는 과정이 비교적 길 어서 최초 계획할 당시의 환경과 진행하는 과정의 환경은 다를 수밖에 없다. 건설산업의 특성상 외부적 요인이 많이 작용하기 때문에 유사한 목적물을 시 공하더라도, 해당 목적물이 완성되는 장소와 그 특성에 따라 생산 방식의 변화 가 필요하므로 시공방법, 원재료, 시간, 투입되는 인원 등에서 차이가 발생할 수밖에 없다. 따라서 당초 계획과 다른 방식으로 시공이 진행되기도 하며, 이에 설계변경과 같은 조정이 발생하는 것이다. 앞서 살펴본 건설공사의 특징에 따라 설계변경이 빈번하게 발생하고 있고, 이 에 따라 계약금액조정과 같은 공사비 문제가 정산과정 등에서 나타나고 있지 만, 아직 민간건설공사에서는 이와 관련한 해결방안이 뚜렷하게 제도화되어 있지는 않다. 특히 발주자와 시공사는 계약을 체결하는 시점의 조건을 바탕으 로 계약금액을 정하고, 각종 계약이행과 관련한 내용을 계약서에 확정하는 것 에 집중하는 경향이 강하다. 따라서 계약을 수행하는 도중에 발생하는 설계변 경과 정산 시점에 추가공사비에 대해 지급하는 문제에 대해서는 상대적으로 소홀하며, 이에 따라 각종 클레임과 건설분쟁이 발생하게 된다. 공사를 진행하 는 가운데 발생하는 클레임이나 분쟁은 공사의 중단으로 이어질 수 있고, 이는 공사기간의 증가와 완료일의 지연으로 이어져 각종 비용과 시간의 낭비를 초 래하게 된다. 또한 분쟁으로 이어질 경우에 발생하는 사회적 비용 역시 불필요 한 낭비라고 볼 수 있을 것이다. 이러한 낭비를 제거하기 위해서는 민간건설공 사에서 설계변경으로 인해 발생하는 추가공사비 청구에 대한 건설분쟁을 제도 적으로 또는 건설계약과 관련된 절차적 측면에서 원칙을 정하고 분쟁을 사전 에 차단할 수 있는 방법을 고민할 필요가 있다. 민간건설공사 설계변경에 관한 제도개선에 대해 몇 가지 제안해보자면 다음과 같다. 계약금액조정 제도를 법제화하고, 시공책임형 CM제도를 활성화하여 설 계변경 최소화를 꾀하며, 민간 영역에 표준계약서를 의무화하거나, 불공정거래 개선을 위한 제도를 도입하고 각종 분쟁을 해결하는 방안을 다각화 하는 것을 제도적, 입법적으로 고민해 볼 수 있을 것이다. 이와 같은 방법을 통해 민간건 설공사에서 발생하는 설계변경에 관한 제도적 문제점을 일정 부분 해소하여 계약당사자의 공정한 계약 체결과 이로 인해 발생할 수 있는 분쟁을 예방할 수 있을 것으로 기대된다.

Under increased complexity and uncertainty of overseas construction projects, it is important for construction companies to improve their own project risk management capabilities instead of risk-taking strategies to secure competitiveness in the overseas construction market. Although most of the risks occur in project execution stage, many previous studies focused on planning stage including risk identification and analysis among PRM process. Therefore, this study aims to verify the effectiveness of whole PRM process during project execution stage through empirical study on participants of overseas construction projects. As the result it was found that first, the factor directly affects the project success is the execution process of PRM. It implies that appropriate actions such as appointing charged manager for risks, timely implementation of responding plan, continuous risk monitoring and updating established plan are the key for contribution to the project success. Second, the importance of communication in PRM is also found, which is not conducted at a specific but throughout the entire PRM process and need to be managed as essential factor for successful PRM..

Recently, defects that occurred during the construction of apartment houses have become a social issue. Defects in apartment houses lead to waste of resources and economic loss, causing psychological and physical damage to customers, and a decrease in reliability and financial loss to construction companies. The purpose of this study was to analyze the impact of defect occurrence according to the difference in project management level in the apartment housing construction stage, and to investigate the extent to which the project manager's experience affects the defect occurrence rate. For the empirical analysis of the study, statistical analysis was conducted using data collected from 130 actual projects. The results of the analysis showed that schedule management, cost management, and quality management had a positive effect on reducing the defect occurrence rate in the execution stage of apartment housing construction, while human resource management productivity had a negative effect. This study theoretically demonstrated the importance of project management, and in practice, showed that schedule management, cost management, and quality management should be faithfully performed in the execution stage to reduce the rate of defects after project completion. It was also suggested that hiring an experienced project manager would help reduce project defects.

Public institutions have a responsibility to ensure the safety of their employees and the public. One way to do this is to implement a systematic safety inspection system based on risk assessments and continuous improvements. This study developed a systematic safety inspection system for public institutions that are ordered construction projects. The proposed system in this study consists of a three-step process: (1) developing safety grade evaluation tables, (2) preparing and conducting safety inspections, and (3) evaluating and improving safety management grades. The first step is to develop safety grade evaluation tables by analysis and diagnosis of the construction site's work type, disaster statistics, and related laws. The second step is to conduct safety inspections using the developed evaluation tables. The third step is to determine the safety management grade based on the results of the safety inspection, and to improve risk factors found during the safety evaluation. The proposed system was implemented in highway construction projects carried out by public institutions. The results showed that the proposed system has two major effects: (1) reducing accident-related deaths and injuries, (2) improving safety management levels by continuous evaluation and improvement. The proposed system can be utilized in construction projects ordered by public institutions to improve the level of occupational safety and health.

Empirical vignettes are from large construction projects in the Greater Stockholm area: The Friends Arena; the Arena City; the new Karolinska University Hospital; and the Stockholm Bypass traffic project.

PURPOSES: This study evaluates the economic value of national highway construction projects using Real Option Pricing Models. METHODS : We identified the option premium for uncertainties associated with flexibilities according to the future's change in national highway construction projects. In order to evaluate value of future's underlying asset, we calculated the volatility of the unit price per year for benefit estimation such as VOTS, VOCS, VICS, VOPCS and VONCS that the “Transportation Facility Investment Evaluation Guidelines” presented. RESULTS: We evaluated the option premium of underlying asset through a case study of the actual national highway construction projects using ROPM. And in order to predict the changes in the option value of the future's underlying asset, we evaluated the changes of option premium for future's uncertainties by the defer of the start of construction work, the contract of project scale, and the abandon of project during pre-land compensation stages that were occurred frequently in the highway construction projects. Finally we analyzed the sensitivity of the underlying asset using volatility, risk free rate and expiration date of option. CONCLUSIONS: We concluded that a highway construction project has economic value even though static NPV had a negative(-) value because of the sum of the existing static NPV and the option premium for the future's uncertainties associated with flexibilities.

A construction project is a designed product made up of labors, materials, and installations in the project positioned on the ground and may include the underground and ground section, and the section in water or on the water surface. It is a civil, industrial, transport, agricultural and rural development, infrastructure, or some other. A key phase in the life cycle of these construction projects is the implementation when building products are made directly with workers, equipment, materials, and managers. If there is a lack of management experience, information, and problem-solving solutions to tackle the risks faced by contractors, especially foreign ones, will fail in controlling the project’s cost. This study was conducted with investigations, discussions, and evaluation of the factors that lead to cost overruns in the construction projects of international contractors in Vietnam. The principal component analysis (PCA) showed that those factors that influence cost overruns these construction projects fall into five general groups, including factors related to (i) the owners, (ii) the foreign contractors, (iii) the subcontractors and suppliers, (iv) state management, and (v) the project itself. Besides, the study proposes solutions to limit cost overruns in construction projects and improve the profitability of international contractors in Vietnam.

The construction industry in developing countries like Vietnam, which incorporates small and medium construction enterprises, is typically more prone to disputes and contract dispute-related lawsuits. A dispute may occur at any time in the life cycle of the project. It is sometimes solved with the intermediation of a lawyer or directly by stakeholders. Understanding the causes of disputes in a construction project not only improves the efficiency of a company but also increases the success of projects. This study was carried out using a questionnaire survey at construction projects in Ho Chi Minh City. Sample data with 117 observations were analyzed to find the disputing factors in construction projects: diversity of working style among the parties; reluctance to work; and poor teamwork. Correlation coefficient on a rank of factors between design consultant and contractor; Design consultant and project owners are positively correlated. The Exploratory Factor Analysis (EFA) analysis identified six groups of factors in construction disputes: cooperation, technology, economics, productivity, information, and behavior. The findings are useful for enterprise practice and provide participants with an overview of sources of dispute. Thus, a more complete risk management plan can be formulated, which will accelerate project progress and improve the likelihood of success.

The study aims to contribute to the improvement of project management in Vietnam. It focuses on developing new critical success factors (CSFs) which can be used to assess the success of project management in the country. This is a promising issue considering the rapid changes occurring within the business environment. The reason is because CSFs carry great consequences on project management issues, particularly in the context of Vietnam, which is currently experiencing many big scale projects involving both local and foreign investors. Two applications are utilised. One is to adapt the business model of Belassi and Tukel (1996) to observe the transitional and emerging economy of Vietnam. The other is to examine the data collected from a survey to examine the new CSFs which can then be used to assess the success of its projects and project management in Vietnam. The research results showed some remarkable differences between CSFs of Vietnam and foreign countries in both number of success factors and its impact levels which should be paid attention by foreign project managers/owners when doing investment and project management in Vietnam. The outcome generated can be useful to project owners/managers as well as policy makers in Vietnam’s business environment.

Recent spread of awareness of residential environment and individual rights makes more environmental disputes than ever. More blasting is needed when construction projects like road, tunnel, railways and industrial area constructions. Noises and vibrations by blasting, therefore, cause many environmental disputes. In this study, we will suggest solution of environmental disputes deduction by case analysing.
