Since Lean Construction has been introduced as a new management approach to improve productivity in the construction industry, much research is in progress to develop lean concepts and principles for better implementation and to get results of the successful adaptation of lean ideas from manufacturing for application in the construction industry. Currently, Lean Construction Institute developed Last Planner System to achieve better workflow and effective planning management. Domestic construction companies are also getting interested in the Lean Construction. However, there are no detailed guidelines how to implement lean system. Thus, this study will provide a guideline for deployment of last planner system, a prototype lean implementation control checklist, and all project participants roles based on the case studies in USA. This study should provide a framework to apply lean construction to domestic construction sites.

생산성은 프로젝트를 관리하는데 있어서 효율성을 측정하는 중요한 지표이다 또한 건설 생산성은 비용 및 일정과 연관성이 있을 뿐만 아니라 프로젝트의 성공 여부와도 관련이 크다. 프로젝트에서 생산성의 중요성에도 불구하고 국내에서의 생산성 관련 연구는 생산성에 대한 기본 개념 및 원칙에 관한 기초적인 연구 없이 정량적인 연구에 집중되어 있으며, 관련 데이터 수도 적은 실정이다. 국내 건설 공사의 생산성을 향상시키기 위해서는 생산성 관리의 정량적친 요인뿐만 아니라, 정성적인 요인까지 관리해야 하며, 저하요인에 따른 체계적이고 세부적인 프로세스 및 기법이 제시되어야 한다 이에 국내 건설 공사의 생산성 관리에 린 건설을 도입하고자 한다. 본 연구에서는 국내 생산성 저하요인과 린 건설에서의 Waste 요인과의 상관관계 분석을 통해 국내 건설 공사 현장에서의 Waste 주요 의미를 살펴보고 두 요인간의 상호 관련성을 파악하여, 린 건설의 프로세스 및 기법을 국내 건설 공사 현장에 적용하기 위한 이론적인 근거를 제공하고자 한다.

Since Lean Construction has been introduced as a new management approach to improve productivity in the construction industry, much research is in progress to develop lean concepts and principles for better implementation and to get results of the successful adaptation of lean ideas from manufacturing for application in the construction industry. Currently, several construction companies in the USA have applied the Last Planner System (LPS), a decentralized system developed by the Lean Construction Institute. Thus, there are demands to share information how other companies implement lean construction, to identify the benefits and barriers of lean implementation in the construction fields, and finally to improve their lean implementation. This study carried out case studies to assess current lean construction projects with the objective to find out how effectively and to what extent lean construction is being adapted by the construction industry. This study will only introduce the Last Planner which has four levels in the LPDS, findings based on interviews with project participants, and observations from the projects. This study will also provide empirically identified success factors associated with lean implementation on the construction site. Finally, the recommendations are offered to support the effort of adaptation of lean construction in the domestic construction industry. Even though lean construction still stood on the bridge crossing from current practice to lean practice, it is the researcher's conviction that lean construction would be successfully adapted to the construction industry in the near future and would be recognized as an effective management innovation.

Since Lean Construction has been introduced in 1992, much research is in progress to popularize lean concepts and principles. Most research focuses on developing lean concepts and tools and strengthening the limited domain of instrumental rationality and technical efficiency. However, the basic concepts of human resource management seem to be ignored by those who advocate lean production. Thus, the lean construction research related to human resource management must be once considered for popularization and activation of lean construction at the beginning stage in the domestic construction industry. Because human resources have a major influence on lean implementation and its success, especially at the beginning stage of lean construction. This paper considers the human resource requirements for the implementation of lean construction in the USA construction industry. The results from the study will provide the foundations to adapt lean construction into the domestic construction industry. Consequently, the study found that lean construction could improve the capability of human resource and human motivation if effectively implemented in the construction sites. Since lean construction emphasizes and focuses on improvement of relationships among project participants, constant application to human resource management is crucial for successful lean implementation.

The Lean Construction is adopted from Lean Principle of Manufacturing Industry in the early of 1990, that has been providing theoretical background and good practical implementation for maximizing customers' satisfaction and improving productivity through minimizing the waste factors in the construction operations. The Last Planner System(LPS), one of the elementary techniques of Lean Construction, aims for improving the work reliability and reducing variability by measuring and managing the daily or weekly performance for overcoming the weakness of recent complex schedule management tools such as Critical Path Method. This research is propose a framework for implementation of LPS conducted by owner in plant construction.

Construction project has various effective factor and many producer in multifarious process of the work. Thus it has many variation. However, Process management up to now is management method of conclusion oriented. So, it do not consider sequency and variation occurrence. In a result that a lot of problems happen. Lean Construction can solve limit of the present management method. And Lean Construction is estimated new management method of process management for reliance on process plan, safety of process and promotion of effectiveness. This study analysed application of real construction project in Lean Construction theory and examined to utilize VSM and TACT for field application.

Current construction project processes pose difficulties for construction management as inefficient communication between project participants seldom accurately reflects the needs of the owner. To solve this problem, lean construction-based Integrated Project Delivery (IPD), which facilitates cooperation and builds trust through the formation of horizontal relationships among participants, is becoming increasingly popular. However, although lean construction-based IPD improves productivity in the construction industry, few studies have focused specifically on developing effective methods that maximize the benefits gained from lean construction-based IPD. This study therefore analyzed success factors for lean construction-based IPD projects by analyzing prior studies to identify factors that support IPD success. Application methods were analyzed and an example of how they are actually used in the field was examined through an in-depth single case analysis. The findings of this research can be applied to support lean construction-based IPD projects in Korea, improving their efficiency and boosting owner satisfaction.

To reform and improve the productivity of construction industry, 1) it should be encouraged to improve the construction production process and 2) it is required to enhance reliability of construction information based on the systematic thinking process. To promote the information reliability created during construction production process, Lean Construction Research Center(LRC2) is developing a supporting system to improve design/material supply/schedule management, functioning to efficiently manage the information created at construction production processes and developing a web based construction information system that provides result management/decision making support/knowledge based information services.

Practical and efficient application of lean construction, which has been proposed as an alternative to the limitations of traditional construction management methods, was developed to facilitate application on site and improve productivity through the fusion of traditional construction management methods. The concepts of Lean Time and Lean Cycle Time, which are the principles of lean construction, were introduced to eliminate waste and smooth flow production and pursuit of perfection, and the goal of establishing and improving the criteria for measurement and improvement was established and the information collection template was configured and applied to ensure reliability of measurement and analysis. Based on this, the project feasibility, reliability, and continuous improvement process were applied to the Field case to verify its effectiveness.
