Since more than 30 different information systems are collecting and providing construction related information, it is difficult for information users to figure out where and how to acquire the required information. Even if the user find the information, it is hard to meet users demand. Because the current systems accumulate the data just as administrative data and can do not connect the information from the different phases of the lifecycle for the specific facility. The information collected and managed in different information systems should be integrated in terms of lifecycle of the facility to improve money for value of public investment, the quality of life by improving quality of the facility and to provide the foundation for big data utilization in the construction industry. This paper suggested strategic planning for the development of the (assumed name) "The Lifecycle Integrated Construction Information Portal" as a foundation to use the data in construction industry, by investigating prerequisites and suggesting conceptual framework of the system.

Recently, BIM (Building Information Modeling) technique is being considered as a critical delivery condition for the public projects according to the increase of best practices by practical application of BIM. However, since existing BIM studies are focused on the design and construction phases, those results are not considering the life cycle of a construction project. Therefore, this study suggests an integrated BIM operation process that enables an application of BIM for each phase of a construction project from planning to maintenance phases and develops an integrated BIM system based on the suggested methodologies. This study developed basic BIM functions and its application process by analyzing information systems in each project phase for a bridge construction project. Besides, this study performed case study and survey analysis for construction managers to verify a practical applicability of the developed system. Therefore, it is expected that the integrated BIM system is going to be utilized as a 3D-based integrated information management system considering life cycle of construction projects.

최근 홍수 시 제방붕괴로 인한 인명 및 재산피해가 증가되고 있어 노후화된 제방 시설물의 안전관리 체계에 대한 필요성으로 국토교통부에서는 국가하천유지보수 종합체계 시스템을 개발하였으나 아직 시범단계로 실무에 적용하여 활용하고 있지 못한 실정이다. 효율적인 국가하천시설에 대한 유지관리를 위한 자료D/B화 및 관리대장, 점검기법, 보수보기법 등을 제시하고 있으나 국가하천에 국한되어 있어 전국단위 하천시설물의 전주기에 대한 통합적인 관리는 반영되어 있지 못하다. 하천시설물 생애주기관리를 위해서는 모든 하천시설물에 대한 이력관리가 필요하나 현재는 시설물의 안전관리에 관한 특별법(시특법) 상의 1, 2종 시설물에 대해서만 시설물정보관리종합시스템(FMS)에서 이력관리를 수행하고 있는 실정이다. 따라서 본 연구에서는 국가하천 및 지방하천에 대한 하천시설물의 생애주기 관리방안을 도출하기 위해 기존의 시스템의 기능 및 구조를 분석하였으며 이를 통해 하천시설물 생애주기 관리방안을 제시하였다.

전 세계적으로 홍수의 발생빈도가 증가함에 따라, 하천 내 홍수피해를 경감하기 위해 설치하는 하천시설에 대한 중요성이 강조되고 있다. 하천시설은 홍수조절, 이수를 위한 흐름의 제어와 유도, 자연환경의 유지 및 개선 등 중요한 역할을 하고 있으나, 구조적으로 물과의 접촉이 많아 물리적 손상이나 노후화가 매우 빠르게 진행되는 특성이 있다. 시설물의 노후화가 지속될수록 안정성을 보장하기 어려워 자연재난의 규모를 증가시킬 위험성이 있다. 하천시설의 선제적 유지관리를 위해, 본 연구에서는 시설물통합정보관리시스템(Facilty Management System; FMS)의 정밀안전진단 결과를 활용하여 시설물의 사용연수에 따른 성능지표의 변화를 기반으로 회귀식 형태의 성능평가모델을 개발하였다. 기존연구와의 비교를 통해 성능평가모델의 적합성을 확인하였으며, 개발한 성능평가모델은 하천시설의 생애주기를 통합적으로 고려함으로써 정량적인 상태를 예측할 수 있다는 장점이 있다. 본 연구에서 제안된 성능평가모델 결과는 하천시설의 생애주기 관리를 위한 기초자료로 활용 가능할 것으로 기대된다.

For the past two decades, 3D/4D CAD research has heel mainly focused on the design and construction phase of a facility life-cycle. However, there has been a general notion that the strength of 3D/4D CAD lends itself to other phases such as planning, operation and maintenance. In this research, a 3D/4D CAD model was generated in a commercial software platform. Then, the traditional 1:fe cycle facility management procedures are reviewed to, see any possible improvement opportunity with the 3D/4D CAD model as an example. A focus group interview, in conjuction with an extensive literature review, produced the list of area where 3D/4D CAD model could significantly benefit the traditional life cycle facility practices. Finally, a questionnaire-based survey was conducted with 155 respondents to statistically verify the feasibility of 3D/4D CAD for life cycle facility management.

It is true that SOC facilities, such as dams, need long life cycles since more time has to be invested for the phases of planning, examination, feasibility study, design, contract, construction, and maintenance. This longer life cycle is easily exposed to the risk. And thus, brings additional cost by the delayed project, convenient loss according to the additional run of use, and benefit lose of not to using the facilities. So, the purpose of this study is to try to find a solution to reduce these time consuming problems which could diminish the whole national competition. Hence, this study is to show efficient, systematical project performance and network model by using reciprocal analyses between the construction period and cost based on economical analysis of each phase of life cycles. In addition, on the basis of these outputs, the Fast Track Method is suggested as an alternative solution as a new Approach in Life Cycle's Analysis.

전 세계적으로 기후변화에 따른 예측하기 어려운 국지성호우의 발생빈도가 증가하고 있으며, 수반되는 돌발홍수를 사전에 대비하기 위해 하천운영의 중요성이 강조되고 있다. 일반적인 하천 시설물 점검 및 보수 계획 수립 시, 시설물의 중요도나 하천의 현황 보다는 행정적인 편의성을 고려하여 구간에 따른 육안 점검 등을 통해 일률적으로 수행되고 있다. 그러나 현재 우리나라의 하천 시설물 중 약 40% 이상이 준공연수가 30년을 초과한 것으로 파악되고 있으며, 노후화된 하천 시설물의 정확한 상태평가에 따른 보수보강 계획수립이 필요한 실정이다. 이를 위해서는 하천 시설물 관리에 있어 다양한 문제점과 관련된 자료를 수집하여 DB화하고, 모델링 및 정밀검사 등을 통해 다양한 각도에서 분석되어야 한다. 본 연구에서는 시설물통합정보관리시스템(Facilty Management System; FMS)에서 제공하는 하천 시설물 관리대장 중 테스트베드에 위치한 수문의 개별부재에 대한 상태 평가지수를 활용하여 시설물의 생애주기를 통합적으로 고려할 수 있는 성능평가모델을 제안하였다. 본 연구에서 제안된 성능평가모델은 하천 시설물의 합리적인 관리체계를 통해 분석된 결과로부터 시설관리자가 하천 관리 및 계획수립에 있어 의사결정을 할 수 있도록 정보를 제공하는 지원 도구로 활용 가능할 것으로 판단된다.

As facilities have become larger, more complex, and advanced, the importance of the facility management in the operation phase of the building is increasing. As a result, the scope of the facility management function is expanding, and the requirements of information are ever-increasing. However, inefficient exchange of information occurs due to duplicated tasks and lack of collaboration among the construction life cycle phases, resulting in cost loss. These low interoperability issues can be complemented by construction information management from a life cycle perspective. Efficient construction information management at each life-cycle stage is derived from the owner's will and is materialized through the construction information handover requirements by the owner. The purpose of this study is to develop an evaluation method of construction information handover requirements for facility management. In order to develop the method, facility management types and business functions are also classified and defined in this paper. Using the methodology proposed by this study, a case-study of evaluating the 'takeover items' submitted by contractors was performed for the purpose of research validation. The results of the case-study found that the most effective areas are in the order of 'legal informations', 'drawings', 'guides', etc. This study can be used as a reference data for deriving handover requirements for construction information at the early stage of the project.

The use of technical proposal tendering has been expanding recently with the aim of effecting cost reduction, quality enhancement, technological development and value realization centered on multifunctional administrative cities, innovation cities, and the Yongsan relocation project. In line with the increasing interest towards life cycle cost improvement measures as an important evaluation category concerning technical proposal tendering, efforts in preparing measures that can execute the security of credibility and objective evaluation concerning architectural life cycle cost are being made. However, problems such as lack of applicable cases of design development and detail design, distortion of initial construction costs concerning the original plan, combination of constant price and current price, the ambiguity of the calculation standards between tendering corporations, inaccuracy of terms, and insufficient compositional formats concerning life cycle improvement measures are being cited. Accordingly, this study sought to propose a measure to improve the compositional guidelines, format, and standards so that a systematic life cycle cost evaluation can be executed for the reliable distinction of each participating corporation, enhanced credibility and objective evaluation of the life cycle cost improvement measure for technical proposals.
