This study proposes FREES(Fuzzy Risk Evaluation Expert System) for analyzing and evaluating risks occurring during the construction process. The feasibility of this system model was tested by virtual scenario. For the development of the model, at first, risk breakdown structure was established based on risks identified in the existing researches, that is quantitative and qualitative. FREES can reflect human cognition process in the risk analysis and evaluation by adopting artificial intelligence fuzzy theory, differentiating the existing quantitative analysis model. The FREES can be applied to all the project phases from planning to operation & maintenance stage.

Development of construction project management information system is accelerated because information management system has become more important by recent complicated and large-sized construction industry. There are many problems to operate PMIS efficiently because no standardized WBS exist in current. This study has identified the problems of WBS in building construction of multi-family house projects with 4 public and private organizations by interviews and compared each WBS. From those facts, this research presents the integrated WBS and the improved application form in PMIS.

최근 건설 산업에서 BIM이 각광 받으면서, BIM 기반의 다양한 엔지니어링 기술 도입 및 프로세스 적용이 시도 되고 있다. 이중 BIM 기반의 프로젝트 운영을 위해서는 BIM의 데이터의 저장, 수정, 배포뿐만 아니라, 관련 주체간의 협업이 가능한 환경이 요구되고 있으며, 이러한 환경 구축을 위해 제조업에서 활용되고 있는 PDM(Project Data Management) 또는 PLM (Product Life-cycle Management) 시스템을 벤치마킹한 CPLM (Construction Project Life-cycle Management)과 같은 BIM 기반 협업 시스템이 등장하고 있다. 하지만 기존의 이러한 협업 시스템의 경우, 건설 프로젝트가 가지는 다양한 계약 방식, 관리 단계, 관련 정보의 체계 등에 대한 종합적 계획 없이 프로젝트의 각 참여 주체들의 기존 관리 방식을 도입함으로써, 당초 BIM 기술을 도입하여 달성하고자 하는 원활한 협업 환경을 구축하는데 한계를 가지고 있다. 따라서 본 연구에서는 최근 BIM 가이드라인의 도입 등에서 시도되고 있는 BIM Planning이라는 개념을 활용하여, BIM 기반 협업 시스템의 구축 이전에 BIM을 관리하기 위한 관리 구조, 방식, 데이터 체계 등을 효과적으로 계획하고, 이를 시스템에 반영시킴으로써 보다 효과적인 BIM 기반 협업 환경이 구축될 수 있는 체계를 제안하였다.

Risk management is an important element for successful management of overseas construction projects. This study reports a case study in which we proposed a risk management planning and procedure for plant construction which can be applied throughout the project life cycle. We analyzed the risk management practices of Korean construction companies by applying the concept of the PRINCE2 method developed in the UK, and proposed a risk management planning and procedure with organizational structure and working process. The suggested risk management planning and procedure was applied to an overseas plant construction project, and produced good results. It is believed that the procedure suggested here can also be aplied to other companies to enhance the competency in the global construction market.

Construction supply chain management focused on materials in construction industry plays a critical role which controls the success and failure of a project. For the efficiency of construction supply chain management, the framework which provides project participants with the information originated from whole construction logistics steps without the omission and discontinuation of information flow is required. The new management framework that can support this environment is necessary because of setting up the complicated and distributed environment including logistics information management by intelligent equipment, co-working management with pre-framework legacy system and various devices(UMPC and PDA etc.) as the information confirmation and electrical transmission tool between the project participants different from former construction supply chain management environment while recently developing ubiquitous technologies such as RFID/USN and intelligent equipment to support logistics process. Therefore, the objective of this study is to introduce the concept of SOA (Service Oriented Architecture) as an alternative of effective information integration under the complex and distributed environment and to propose the SOA-based application model for building intelligent construction supply chain management framework.

The risk in the constructions projects is extremely diverse because there are too many indefinite factors. Therefore, Performance Measurement Baseline(PMB) is needed regularly during the construction process. However, nowdays, the PMB in the constructions projects is for contractors' PMB and Performance Management(PM). Clients have a lot of difficulties to control and manage the projects. Therefore, this paper classifies schedule and cost data of the public apartments houses which is a actual cases into types and then conducts regression analysis and deduces a regression. In addition to this paper establishes the Work Breakdown Structure(WBS) and suggests the PMB for the clients through using that.

Plant construction projects usually take much higher uncertainty and risks than the projects from other domains. This implies the importance of plant construction project management should be more emphasized than the other domain. Especially, the overall successes of the projects often depend on the performance of process planning and scheduling performed at the initial stage of the project. However, most plant construction projects suffer great difficulties in establishing proper process planning and scheduling timely because of unstructureness and dynamicity of environment of the project itself In this paper, we propose a knowledge-based process planning and scheduling approach in a plant construction domain to cope this problem. First, we modulize process planning knowledge and present the knowledge representation scheme. Second, we propose an inferencing mechanism to build a process planning for plant construction based on the represented process planning knowledge. Since our approach automate the initial process planning, which was usually done by manual way, it can improve the correctness and also completeness of the process plan and schedule by reducing the time to plan and allowing simulations on the various situation. We also design and implement this our approach as a real working system, and it is successfully applied to real plant construction cases from a leading construction company in Korea. Based on this success, we expect our approach can be easily applied to the projects of other areas, while contributing to enhancement in productivity and quality of project management.

The importance of early project planning is broadly recognized for construction projects. From the planning step, If extensive historical data related with the project is applied effectively, It can be major resource for estimating cost and project scope. However, The accumulation, analysis, and application of historical data is not sufficient in Korea. So useful information of construction project has disappeared. In order to solve the problems, Project Historical Data Management Systems is need to be developed. The purpose of this study is to analyze current problems and to find the method to utilize historical data in similar project.

Recently, significance of efficiency in construction projects have been increased. So effective new delivery systems are required to improve project quality and value. Those systems could also reduce period, cost, risk and waste of the construction. Also, as current government aims 'Low carbon and Green growth', it is important to manage integrated supervision from the pre-design stage to the operation stage. In USA, AIA suggested IPD which encourages mutual cooperation among stakehklder to improve the productivity. Therefore, this study analyzes the characteristics of the IPD and deduct Present condition and Perception of Domestic Construction Environment to Introduce IPD.

It is very important to manage the risk in building construction because construction process has too many internal risk compared with others. So construction managers need more developed risk management system than the Present. While the study for the solution and management of generated risk is comparatively enough, the effort to confirm the risk of construction phase on pre-construction phase haying an major effect on total duration, is insufficient. For supporting the schedule risk management of pre-construction, this study suggests the reclassified risk breakdown structure and the investigation form for advance preparations on pre-construction Phase, which help the Poorly experienced construction manager to make more correct decisions and efficiently to execute risk management.
