Building Information Modeling (BIM) comes to be implemented into architectural design, construction, and maintenance in Japan in order to convert design information thoughout a construction project. However, various problems are taking place in data transaction. It is not also clear about the role and the responsibility of the architects and the enginners in charge.There is a movement to establish a BIM manager as a general coordinator concerning BIM in Singapore and other countries, though it is not yet popular in Japan. This paper deals a BIM manager as a new profession in a construction project. The function and skills necessary to a BIM manager is analyzed, and the strategy of Japanese general contractors is discussed. General contractors from Japan are operating BIM in Singapore compatible with open system of supply chain. This style is different from the one in Japan even they belong to the same company. In this paper it is analyzed based on the survey in detail.

As a construction project is recently becoming large-scaled and complex, construction process plan and management for successful performance of a construction project has become more important. Especially a reasonable estimation plan of activity duration is required because the activity duration is directly related to the determination of the entire project duration and budget. However, the activity duration is used to estimate by the experience of a construction manager and past construction records. Furthermore, the prediction of activity duration is more difficult because there is some uncertainty caused by various influencing factors in a construction project. This study suggests an estimation model of construction activity duration using neural network theory for a more systematic and objective estimation of each activity duration. Because suggested model estimates the activity duration by a reasonable schedule plan, it is expected to reduce the error between planning duration and actual duration in a construction project. And it can be a more systematic estimation method of activity duration comparing to the estimation method by experience of project manager.

In the highway engineering, the performance, quantity and status of machines available for the project have direct impact on the project time. For instance, the status of machines, such as working or in trouble, have great influence on the activity execution. Therefore, while scheduling the project, the project manager always increases the spare machines or prolong the activity time to avoid delaying the project time when some of the machines are in trouble in construction site. However, how many are the spare machines and how long are the prolonged activity time, which are estimated subjectively by the manager. This subjective estimation has been criticized for systematically overestimating or underestimating quantity of the machines and the activity time. In the paper, we propose and prototype a model to simulate the status of the machines in construction site, and then to evaluate the schedule feasibility considering the performance, quantity and statues of the machines involved.

CM방식은 CMr과 발주자가 일체가 되어 프로젝트의 전반을 관리하는 방식으로, CMr은 기술적 중립성을 유지하면서 발주자 관점에서 설계 발주 시공의 단계에서 각종 관리 업무의 전부 또는 일부를 실시하는 것이다. 건설과정에서 새로운 전문직으로 발전하고 있는 CMr은 계약에 따라 업무와 서비스 범위가 확정되므로 높은 수준의 윤리가 요구된다. 본 연구에서는 관련법에서 제시하고 있는 CMr의 법적지위와 업무수행에 따른 윤리기준과 윤리특성을 제안하였다. 결론으로는 첫째, 건설사업관리업무의 법적 특성은 관리업무를 부여하는 사람과 부여받는 사람의 계약관계에 따라 사람의 노동력을 제공하는 형태로 수행되는 위임계약, 과실책임, 선관주의 의무를 갖고 있다. 둘째, 건설사업관리의 업무 특성은 조정자의 역할, 전문기술 서비스, 발주자 설명책임과 공공성을 갖고 있다. 셋째, 이러한 업무 특성에 따라 전문가로서 건설사업관리자의 윤리평가기준은 의도, 행위와 결과로 분류하고, 이를 업무 특성과 연관시켜 덕윤리, 의무론, 결과론으로 제안하였다.

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.

Construction project is necessary element for human life to upgrade the quality and convenience. However, due to its contradictory nature to the environment preservation, environmental pollution and damage, deterioration of natural scenery, noise/vibration, water quality pollution, etc. caused in the process of construction greatly affect the environment. For the building or construction project, its possible impact on environment during construction work and after completion must be predicted at its design phase, which will result in the completion of the architecture convenient for human being with its environmental pollution reduced to minimum level. In this study, the checklist of environmental factors was suggested, which should be taken into account at its design phase in conducting the construction work. Proposed checklist was linked with the developed web-based system for the convenience of users like designer and construction manager, etc. It is expected that the checklist suggested by this study will help the designer and construction manager to continue the steady development from the environmental viewpoint during the design phase.

Purpose: The purpose of this study to determine the effect of distribution transformational and transactional project manager leadership style on the extra-role performance of project team members using multi-level modelling analysis. Research design, data and methodology: The role of psychological factors as the mediating variable namely is self-efficacy in the effect of project manager's leadership style on the project team members' performance was also studied using the Monte Carlo bootstrapping method. The sample of the study consisting of 370 project team members from 74 contractors registered with the Construction Industry Development Board in the Klang Valley was selected using a simple random sampling and a survey using a questionnaire. Results: The findings showed that the transformational leadership of project managers was a dominant predictor of extra-role performance of project team members. Furthermore, the study show the self-efficacy of project team members acted as a mediator in the relationship between transformational and transactional leadership of project manager leadership on the extra-role performance of project team members. Conclusions: The findings are expected to be used by the relevant parties in planning, arranging and implementing efforts to improve the work performance and ensure that projects are implemented according to the specified specifications.

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.

건설산업의 조직운영은 생산성 및 원가절감에 중요한 요소이다. 그러나 현재 조직개선을 위한 노력이 부족할 뿐만 아니라 조직의 평가방법 또한 체계적으로 갖추고 있지 않다. 본 연구는 공동주택 및 오피스의 현장조직원 선정실태 분석을 통하여 현장조직인의 선임방법, 직급, 및 인원수 결정기준, 자격조건등을 종합하여 제시하였고, 현장 조직원의 선정절차를 제안하였다. 또한 현장관리조직원에 활동에 대한 평가실태 분석을 통하여 현장소장에 대한 평가항목 및 배점, 준공현장에 대한 평가항목 및 배점을 제안하였다. 따라서 본 연구의 결과는 건설공사의 현장관리조직원의 선정 및 평가에 대한 기준을 체계적으로 갖추지 못한 건설기입에 효율적인 조직운영을 위한 기초자료 제공함으로써 생산성향상 및 원가절감에 기여하고자 한다.
