Construction industry is overwhelmed by delay and often has suffered cost and time overrun. In this context, Last Planner System (LPS) has been considered as a very useful tool for the management of the construction process. Many previous studies have reported its effectiveness in construction performance. This study aims to evaluate the level of importance of the Last Planner processes in the Vietnam construction industry (VCI), and analyze the existing barriers when implementing these processes in construction management. These barriers were collected based on previous studies from International Group for Lean Construction (IGLC). A survey was carried out through questionnaire. The respondents are been experienced people in construction project management. There are four processes of LPS that were investigated including master schedule, phase schedule, lookahead plan, and weekly work plan. The results showed that master schedule is the most important item when performing a construction project in the VCI. The highest degree of agreement belongs to 'owner - contractor' pair with 77.1% importance indices; whereas the lowest belongs to 'consultants - contractors' pair with 63.8% importance indices. Eventually, three barrier factors were extracted from factor analysis technique with 62.2% of variance explained.

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.

A nuclear power plant construction project normally involves a large construction work of which the total project cost is over 5 trillion Won, Such a large-scale construction project has the risks of schedule delay and quality degradation due to increase in project cost, because designs are changed due to design errors. The reasons for design changes during installation are 1) insufficient engineering capability of the owner, 2) information discontinuance due to the multiple package method, and 3) inefficient constructability review processes. Accordingly, this study proposes, through problem analysis, a method of developing a constructability review system that utilizes constructability review processes and a data-based technology (3D modeling) that are optimized for nuclear power plant construction projects. It also presents a method of establishing a system for reviewing constructability in which constructability review processes and a Database (3D model, Schedule, Design change Items) are linked each other.

건설업은 일반 제조업의 생산과정과는 달리 다양한 참여주체들이 모여 프로젝트 성공이란 하나의 목표아래 정보를 공유하며 업무를 진행하므로 한 프로젝트마다 일시적인 팀워크가 형성된다. 다양한 참여주체들은 건설공사의 단계별 역할이 다르며, 업무 및 이에 따른 이해관계 역시 복잡하게 얽혀있다. 건설프로젝트의 효율적인 관리와 경영의 최적화를 위하여 CM제도가 도입이 되었다. 따라서 CM제도의 성공을 위해서는 주요 참여주체(발주자, CMr, 설계자, 시공자)의 협력관계가 요구된다. CM제도가 도입된 이래 성공적으로 사업을 수행하기 위한 일환으로 CM성과측정에 대한 많은 노력이 있었으나, 발주자의 입장에서만 바라본 항목으로 측정되고 있다. 이에 본 연구에서는 CM성과를 객관적으로 측정하기 위해서 건설프로젝트의 주요 참여주체인 발주자, CMr, 설계자, 시공자의 균형적인 시각을 바탕으로 한 성과측정 항목의 필요성을 제기 하고자 한다. 건설프로젝트의 주요 참여주체인 4자(발주자, CMr, 설계자, 시공자)의 협력관계를 살펴본 뒤 각 주체에 따라 성과항목에 대한 인식차이가 있다는 것을 검증하였다.

Currently, there is insufficient research on the construction management performance since the CM system was introduced in Korea. For successful completion of construction projects, active use of construction mangers on projects is necessary by introducing construction management to the projects. In view of this, this study analyzed the annual CM performance from 1996 to 2013 but for the past 5 years from 2009 to 2013, a detailed analysis was carried out. For different sectors, CM performances were divided into public and private sectors, for project types, construction, civil and others, for project phases, pre-design, design, construction and post-construction phases, for contract types, sole and joint contract types, for project scale, the amount of the projects was taken into consideration and they were divided into large, medium and small scales and for the types of projects, they were divided into, shops, department stores, shopping centers, hospitals, government buildings, hotels, accommodation facilities, factories, buildings for workshops, office buildings, stadiums, playgrounds, schools and other construction types and all the data divided into such categories was analyzed. The results in this study can be used as a basic reference for studies in analysing construction management performances.

일반적으로 건설사업관리는 발주자를 위한 방식과 시공자를 위한 방식으로 구분되고 있으나 현재 국내에서는 사업관리 기능을 포함한 감리를 중심으로 대부분의 프로젝트가 진행되고 있는 실정이다. 이로 인하여 사업참여자간의 업무관리가 복잡하고 감리자 및 건설사업관리자가 효율적인 사업관리업무를 수행하는데 어려움이 있다. 따라서 전문화되고 체계적인 사업관리절차를 포함한 통합사업관리시스템의 활용이 어느 때보다 절실히 요구된다. 본 연구에서는 전주월드컵경기장의 CM사례를 통해 현행 CM업무의 현장적용상의 문제점을 분석한 후 통합사업관리시스템과 CM의 발전방향을 구체적으로 제시하는 동시에 현장 CM에 대한 개념구축, CM업무 수행 지침서 작성 등의 현장 건설사업관리업무의 향후 발전방향을 제시하고자 한다.

In the past, a strategic management of work demands has been increasingly challenged to design-build (DB) firms. Such a management is capable of providing sufficient profitable impact of a project on them. Total project profit is mainly related to actual resources, work completion time, amount of rework, and costs. The degree of recycling work packages in the DB project delivery system is used as a measure of the quality of the performed work. However, there are few models available to evaluate the impact of a demand management strategy on the DB firms and to predict its behavior. We propose a decision-making support model as an aid for assessing the amount of rework and for predicting project profit resulting in a convincible demand management strategy. This model is constructed by using a dynamic feedback approach that can analyze the problems arising in complex managerial systems. For the purpose of illustration, widely acceptable strategies were applied into the model to explore their impacts on the DB firms. The results indicate that the model is helpful for the managers in selecting the most appropriate demand management strategy for successfully achieving their objectives.

Construction and engineering is one of the world largest industry. Yet, it Is one of the most inefficiently operated industry. Since buildings are not constructed by mass production, construction projects usually require intense communication and collaboration between participants, who are usually widely dispersed. That is the main reason for the inefficiency. eWorks21 that we developed in this research, is a project management system that can improve communication and collaboration among project participants using the Internet. eWorks21 can reduce project life-cycle, costs, and increase revenue, resource utilization, controls, transparency, and competitiveness, which will eventually provide infrastructure for knowledge management of construction projects. In this research, we classified currently available project collaboration systems, and analyzed the benefits gained by using project collaboration systems. Then we describe the implementation of eWorks21, and discuss employment and utilization strategies of project collaboration systems.

Vast quantities of environmental pollutants from construction projects are causing significant damage to nearby local communities and thus generate environmental complaints. The construction company, responsible for compensating and resolving environmental complaints, suffers economic damages due to additional expenditures and schedule delays in construction projects. Meanwhile, the construction industry can stagnate from a broader perspective. Therefore, this study aimed to propose a framework for developing an automated management system which consists of two models for environmental complaints in construction projects: (i) the prediction model: a model for predicting environmental complaints based on factors related to environmental complaints; and (ii) the prevention model: a model for providing construction companies with the optimal prevention measure to effectively prevent environmental complaints according to the results of the prediction model. In addition, the algorithm for integrating the developed models into the management system in construction projects was proposed. Eventually, the application of the management system to construction projects can ensure the profitability of construction companies and mitigate damage from environmental pollutants to the nearby local community.

Construction project is necessary element for human life to upgrade the quality and convenience. However, due to its contradictory nature to the environment conservation, environmental pollution and damage, deterioration of natural scenery, noise/vibration, water quality pollution, etc. caused in the process of construction greatly affect the environment. The purpose of this study is to propose checklist for environment management can be used in construction phase. For this, we went ahead with the research by studying the existing research related to environment-friendly construction project management both at home and abroad, investigation and analysis of environment-related laws and ordinances, and drawing the checklists for natural environment and living environment at the construction phase. As a result, we were able to compile a checklist for nine items including geological features, animals and plants, use of soil, quality of air, water, and soil, construction wastes, noise, vibration, recreation, and sceneries. The checklist is structured in 4 grades and coded so as to allow it to be developed with the use of computer system in future. We hope that the checklist presented in this study will help lead the managers at the construction phase in construction development sustainable from the perspective of environmental conservation.
