PLM(Product Lifecycle Management) is one of innovative manufacturing paradigms which leverages e-business technologies to allow a company's product content to be developed and integrated with all company business process through the extended enterprise. In these days, most construction companies also make an effort to enhance their systems for creating, sharing and managing information to improve business efficiency through entire lifecycle of project execution. Because of different needs, business process and diverse engineering activities such as design, structural analysis, installing simulation, documents and data managements, a new paradigm for construction companies is needed to manage and share the entire workflow, and information in total project lifecycle. In this paper, we conducted user requirement and business process analysis of constructions to design C-PLM system which is a PLM system for effective management of civil project and engineering activities. Also, we implement C-PLM system based on commercial PDM system, and applied it to civil project as case studies.

There is a high confidence based on scientific evidence that climate is changing over time. Now climate change is considered as one of the challenges facing the construction industry. As no project is risk free and climate change has a strong impact on the different phases of the construction project lifecycle. This research aimed at providing a platform of knowledge for the construction management practitioners about the impacts of climate change on the construction projects lifecycle, identify the most dangerous climate change factors on the construction project lifecycle, and identify the most affected phase by climate change factors through the construction projects lifecycle. The study depended on the opinions of civil engineers who have worked in the construction projects field among the reality of Gaza Strip. Questionnaire tool was adopted as the main research methodology in order to achieve the desired objectives. The questionnaire included 127 factors in order to obtain responses from 88 construction practitioners out of 98 representing 89.79% response rate about the influence of climate change on the generic lifecycle of construction projects. The results deduced that the most significant influence on the construction project lifecycle was related to the extreme weather events, rainfall change, and temperature change respectively. There was a general agreement between the respondents that the most affected phase by temperature, rainfall, and extreme weather events is the execution phase. The results also asserted with a high responses scale on the need to alternative procedures and clear strategies in order to face the climate change within construction industry.

A system to analyze, assess and manage the health performance of resources and spaces throughout the project lifecycle shall be established to ensure sustainable healthy buildings. Decisions made in the planning, design, construction, and operation and management (O&M) phases must help sustain the health performance of buildings at the level specified by clients or the relevant laws. For this reason, it is necessary to develop a model to ensure the consistent management of performance, as such performance varies according to the decisions made by project participants in each phase. The purpose of this research is to develop a Lifecycle Health Assessment Model (LHA) for sustainable healthy buildings. The developed model consists of four different modules: the Health-friendly Resources Database (HRDB) module, which provides health performance data regarding resources and spatial elements; the Lifecycle Health-performance Tree (LHT) module, which analyzes the hierarchy of spatial and health impact factors; the Health Performance Evaluation (HPE) Module; and the Lifecycle Health Management Module, which analyzes and manages changes in health performances throughout the lifecycle. The model helps ensure sustainable health performances of buildings.

Purpose: A railroad project is a complex system with large construction costs in the initial stage and ongoing operating costs over its lifecycle. Current railroad projects tend to be based on construction options, which leads to huge deficiencies in operating costs. This phenomenon results from a lack of appropriate tools to accurately estimate a railroad project's lifecycle costs. This study attempts to analyze the major components of railroad operating costs and to propose a decision-making system for analyzing the long-term lifecycle costs of railroad projects. Research design, data and methodology: We review the literature and analyze the current status of railroad operating costs in Korea and overseas. Based on previous projects, a framework for project options and operating costs is proposed. The framework is applied to actual railroad projects to demonstrate the validity of the model. Results: Case analysis shows that our framework is comprehensive in analyzing the primary aspects of railroad operating costs and plays an effective role in choosing various railroad project options. This study points out that the railway project operates inefficiently because estimating long-term costs without reflecting specific project options causes many errors. Conclusions: A major contribution of this study is the development of an improved framework for accurately estimating operating costs and providing policymakers and engineering firms with a holistic decision support system. Detailed components in estimating operating costs of the railroad business are discussed. And we present a decision-making tool that policymakers and private businesses can use in planning the railroad business.

This research was aimed at studying the situation, problems, and requirements for digital collection lifecycle management of Thai theses and dissertations. The mixed research method used was composed of: (1) Study of the problem and situation in which the qualitative method was applied. The research site covered 10 higher education institutions where the Thailand Digital Collection (TDC) project is operated. The informants were key administrative officers of the TDC project of each institution. In-depth and structured interviews were conducted on an individual basis to obtain the most accurate answers. (2) Study of requirements based on the quantitative research method to survey the requirements for the digital collection management system for Thai theses and dissertations from 84 purposively-selected TDC project officers and 527 end users selected by accidental sampling, totaling 611 samples. Research findings are as follow: (1) The study of the situation and problems of digital collection lifecycle management shows that Thai higher institutions systematically manage their digital collection. The management lifecycle is consistent with the Guidance documents for lifecycle management of ETDs, which included seven steps: program planning, creation, submission, and ingestion, access and retrieval of digital objects, archiving and preservation, evaluation and assessment, interoperation (creation of institutional collaboration), and development of link data. (2) The study of requirements for digital collection management of Thai theses and dissertations shows five system requirements: acquisition and gathering, digitization, metadata standards, management of rights, and storage and retrieval, all of which are at M (mandatory) and D (desirable) levels.

BIM (Building Information Modeling)은 토목 구조물의 3차원 객체모델을 기반으로 기획 단계부터 설계, 시공 및 유지보수 단계에 이르기까지 대상 구조물에 관련된 모든 정보를 통합적으로 생성, 관리하는 기술이다. 현재 국내외의 다양한 건설 산업 분야에서는 건설 생산성 향상을 위하여 BIM 기술을 도입하여 활용하고 있다. 그러나 이러한 BIM 기술을 적용하여 효율적인 엔지니어링 업무를 수행하기 위해서는 무엇보다 참여 주체간의 협업 시스템이 필요하다. 따라서 본 논문에서는 토목 프로젝트 참여 주체의 요구사항을 분석하여 건설 프로젝트 관리를 위한 BIM 기반의 CPLM (Construction Project Lifecycle Management) 시스템을 설계, 개발하였다. CPLM 시스템은 건설 프로세스 단계에 따른 정보의 관리와 공유가 가능한 환경을 제공한다. 향후 CPLM 시스템을 실무에 도입함으로써 기존의 업무 프로세스를 개선하고 데이터를 효율적으로 관리할 수 있게 되어 의사결정에 도움을 줄 수 있을 것으로 기대된다.

건축물 수명주기 동안 생성되는 정보를 통합관리하고 재활용하여 경제적 손실을 줄이고 이윤을 극대화하려는 과정을 Building Information Modeling (BIM)이라고 한다. 기존의 건설관리기법들과 비교하여 양질의 건물을 더 싸게 빠르게 지으려고 한다는 점에서 그 궁극적인 목적이 다르지 않지만, 기존의 기법들이 경영관리기법적인 측면에서 접근하였다면, BIM은 시스템적인 면에서 접근을 하고 있다는 데에 그 차이점이 있다. 본 논문은 BIM의 정의와 배경에 대해서 고찰하고, BIM을 위하여 필요한 핵심기술들의 현재와 미래에 대하여 논의하였다.

현재 국내 건설사업의 건설 관련 정보는 약 30개 기관의 개별시스템으로 분산되어 수집 관리되고 있어 정보보유 기관, 정보항목 및 내용, 조회 방법 등을 파악하기 어렵고 데이터의 단절로 활용에 한계가 있다. 기획, 설계, 시공, 유지관리 등 시설물 및 건축물의 생애주기 각 단계별 정보가 발주 업무수행 과정에서 형성되는 행정자료 구축의 성격에 머물러 전 생애주기에 걸친 이력정보 데이터 구축과 그를 바탕으로 한 수요자 맞춤형 빅데이터 활용이 부족하다. 공공시설 투자 및 관리 효율화를 통한 경제성 제고, 부실과 비효율의 최소화를 통한 품질향상, 시설물 건축물의 성능 향상을 통한 안전 및 삶의 질 제고 등을 위해 정보의 통합관리가 필요하다. 이에 본 연구에서는 시설물의 생애주기 단계별로 각기 다른 정보 시스템(DB)에 흩어져 관리되고 있는 정보를 파악하고, 이를 통합 활용할 수 있는 기반 구축을 위해 (가칭) "생애주기통합 건설정보포털"의 개념적 구성을 제안하고, 물리적 구축에 앞서 짚어봐야 할 제반여건 정비 등 추진방안을 제시하였다.
