건설부문의 정보화를 위해 국토해양부는 건설CALS(Continuous Acquisition & Life-cycle Support)사업을 추진하고 있다. 건설CALS란 건설사업의 설계, 시공, 유지관리 등 전 과정의 생산정보를 발주자, 관련업체 등이 전산망을 통하여 교환 공유하기 위한 정보화 전략이다. 건설CALS사업은 시스템 개발 부문과 건설정보 표준화 부문으로 구분할 수 있는데, 개발된 시스템으로는 건설사업관리시스템(건설사용, 발주기관용), 시설물유지관리시스템, 건설인허가시스템, 용지보상시스템, 건설CALS포탈시스템 등이 있다. 건설CALS시스템에는 건설사업의 공정관리, 원가관리, 안전관리 등의 많은 기능이 있음에도 불구하고 최근 그 중요성이 부각되고 있는 환경관리 기능은 없는 실정이다. 본 논문에서는 건설CALS시스템의 현황을 분석하고 환경관리가 가능한 체크리스트와 매뉴얼을 개발하여 시스템으로 구현하기 위한 방향을 제시하고자 한다.

건설CALS 시스템은 건설사업의 전 과정에서 발생되는 방대한 정보를 관리 제공하는 정보시스템으로 건설CALS 포탈 및 항만건설통합정보 등 6개 단위 시스템으로 구성되어 있다. 그러나 각 시스템들의 개발 시기가 개별적이고 하드웨어 구성 또한 독립적으로 이루어져 신규 시스템 추가 시 기존 시스템과의 연계가 어려우며 별도 하드웨어 및 소프트웨어를 추가하여야 한다. 또한, 시스템 운영 중 발생한 유휴자원을 다른 시스템에서 활용하지 못하기 때문에 시스템 운영 측면에서 비효율적이다. 이에 본 논문에서는 클라우드 컴퓨팅 기반 건설CALS 시스템 아키텍처를 설계하였다. 설계한 아키텍처는 시스템 확장이 용이하고 자원에 대한 동적 할당과 더불어 잉여 자원에 대한 높은 활용성, 시스템 가용성을 증대 시킬 수 있어 효율적인 시스템 운영이 가능하다.

Strategic alliance between corporations is essential to build a CALS system. Specially, companies cooperate one another to accomplish the shared environment in the system. During the construction of the CALS system, we can apply the concepts of ILS and SCM to develop the breadth and depth of shared environment between firms. In order to build such intended environment in the CALS system, we propose five dimensions with 30 variables to be considered. These dimensions are Information Sharing, Task Sharing, System Sharing, Parts and Facilities Sharing, and Institution Sharing. Structured interviews were peformed to measure the degree of shared environment designed in 7 CALS pilot systems in Korea. The results show that the level of the shared environment in the context of vertical relationships between firms in the CALS systems is fairly high. In contrast, the level of the sharing between competing companies in horizontal relationships is relatively low in most of the pilot systems.

The Public Data Act mandates that every public institution must make efforts to facilitate convenient access to public data for all and take necessary measures to universally expand the right to use such data. Furthermore, it specifies that the head of a public institution must provide the data held and managed by that institution to the citizens. The Construction Project Information Disclosure Service aims to increase the utilization of data within the Construction CALS System, creating new added value by disclosing information and fostering communication. This service seeks to enhance public interest and transparency, support the creation of new businesses based on construction project data, and stimulate related industries. Since 2019, a total of 26 types of information have been disclosed through this service. As the volume of disclosed information continues to increase, there has been a consistent demand for reducing burden on data providers and enhancing user functionality. This study analyzes the current status of the Construction CALS Information Disclosure System to identify its existing challenges. Subsequently, it establishes a systematic approach to the data opening process and proposes enhancements to information disclosure and search functionalities for addressing these challenges.

This study aims to develop an approach to construct IWSDB for National Defense CALS. Along with the introduction of Korean version of CALS conception, it is essential to analyze the national defense system with a new information technology for the construction of IWSDB. A long-tenn goal of CALS is to construct fully Integrated Data Environment (IDE) and establish IWSDB for the application of CALS conception to the life cycle management of weapon system. IWSDB is a set of databases that contain digital data. It supports common interface of data objects and databases throughout the life cycle management of weapon system, including design, engineering, analysis, manufacturing, operation, and logistics. etc. The goal of this study is threefold. First, we propose a right direction for the establishment of Integrated Data Environment. For the integrated database technology, we use the five schema architecture and the distributed object oriented technology that will lead to the "share of data." Second, we present the most effective IWSDB architecture for defense CALS, which will provide the efficient data sharing by business process modeling. Third, we suggest that IWSDB should be constructed based on the process which is related to the acquisition and logistics of weapon system for the national defense, and at the same time it should be implemented with GITIS for government agencies and CITIS for the industries in order to obtain the efficient data sharing.

The purpose of this study is to develop the standards for construction documents. The standards will facilitate efficient exchange and sharing of construction documents among the participants such as owners, designers, constructors and other related parts throughout construction work process. For this reason, this study is intended to define the requirements for establishing XML-based electronic document standardization system, and to prepare the plan for developing XML electronic document in a consistent way.

본 연구는 토지 보상비의 추정 모델 개발을 위해서 건설 CALS (Continuous Acquisition & Life-cycle Support) 시스템의 내부데이터와 개별공시지가 및 표준지 공시지가 등의 외부데이터, 그리고 개발된 추정 모델의 고도화를 위한 개별공시가 데이터를 기반으로 생성된 데이터를 활용하였다. 이렇게 수집된 3가지 유형의 데이터를 분석하기 위해서 기존 선형 모델 또는 의사결정나무 (Tree) 기반의 모델상 과적합 오류를 제거할 경우 매우 유용한 알고리즘으로 Decision Tree 기반의 Xgboost 알고리즘을 데이터 분석 방법론으로 토지 보상비 추정 모델 개발에 활용하였다. Xgboost 알고리즘의 고도화를 위해 하이퍼파라미터 튜닝을 적용한 결과, 실제 보상비와 개발된 보상비 추정 모델의 MAPE(Mean Absolute Percentage Error) 범위는 19.5%로 확인하였다.

Currently, it is not popular to use the STEP based product information in the construction drawing files, in spite of the importance and possibility of using various product data in drawing files on the CALS/EC environment. This paper aims to demonstrate a construction drawing information management system based on ISO 10303/STEP. To achieve this aim, the authors have analyzed the current construction drawing information classification hierarchy widely used for domestic and international, and examined the material data connection mechanism within CAD drawing data, and finally investigated the management systems for construction documentations and drawings in a public companies. Therefore, the expected benefit of the proposed system is that STEP drawing information management will be done standardization and the information of STEP construction drawing can be managed, shared and supported design business through materials data connection.

This paper is a type of business representatives who are responsible for the burden he want to relieve. In addition, to ensure transparency and to contribute to the Elimination of irregularities in cracking down on overcharging to research. In order to avoid duplicate entry of fixed checkpoints of modern equipment was installed in the automatic collection of information inspection. And, if the information is the same information to crack down imposed the Road Fine system linkage system Constrution CALS system to research. Land administration office imposed a fine after confirmation information to crack down on the auditory system, the auditory crackdown imposed fine and proceed to determine the status of your work since. This study was carried out and any future crackdown on overcharging gathering information for the efficient production of surgical intervention for improved accuracy considering that frequency.

Information technical dependence degree is coming to be high from constructive information-oriented field. The size and complexity of constructive information are increasing and consequently, the standard for a construction information resource management becomes important. Currently the certification about construction information standard is being enforced part system and information-oriented level etc. from domestic. So we have a plan which will propel the diffusion strategy for the practical application of constructive information standard with introduction of the certification system about construction information standard. For a certification system preparation, we studied a feature and definition about construction information standard and analyzed domestic and foreign case. From that, we accomplished a classification and an analysis about construction information standard becomes the object of certification. And then, we selected the object of the certification through deriving necessities of certification about each construction information standard and considering the priority at the time of introduction. Finally we suggested an certification institutional operation plan about the object which is selected. Held a consultation meeting about the fact where the professional knowledge or technique is demanded and established secured directivity about authentication institutional operation plan and professionalism.
