Nowadays BIM(Building Information System) is applied to the public construction delivery system. BIM can help communications between project applicants through the extraction of the exact and prompt information. It also increases the efficiency of planning, construction, economic feasibility and maintenance in the whole project. Due to increasing demands of BIM, project evaluation and its process on the final deliverables have been in major interests. Thus, through the analysis of the current BIM project, characteristics, types and applications have been researched. We have discussed completeness, relationship and planning of BIM data, which are the standards of evaluation.

토공사는 타공종에 비하여 건설공사에서 차지하는 비용 및 공사기간의 비중이 높다. 이에 따라 토공사는 건설공사의 생산성에 높은 영향을 미치게 되는데, 종래의 토공사 시스템에서는 숙련된 굴삭조종자의 휴리스틱스에 의한 토공사 계획 및 토공작업을 수행하는 노동집약적 프로세스를 고수하고 있어 생산성을 높이기 힘든 상황이다. 이러한 당면과제를 극복하고자 본 논문에서는 BIM 기반의 지능형 굴삭시스템을 소개하며 굴삭 작업 계획 생성 시스템, 원격조종 및 자율 굴삭 작업에 필수적인 Human-Machine Interface(HMI), 웹기반 Project Management Information System(PMIS)이 개발되는 과정에서 적용된 BIM 요소기술에 대하여 검토하고, 적용된 결과를 제시하고자 한다.

Many conventional management methods have emphasized the minimization of required resources along the supply chain. Accordingly, this paper presents a proposed method called the Virtual Design and Construction (VDC)-aided system. It is based on object-oriented resource control, in order to accomplish a feed-forward control monitoring supply chain logistics. The system is supported by two main parts: (1) IT-based Technologies; and (2) VDC Models. They enable the system to convey proactive information from the detection technology to its linked visualization. The paper includes a field study as the system's pre-test: the Scaffolding Works in a LNG Mega Project. The study demonstrates a system of real-time productivity monitoring by use of the RFIDbased Mobile Information Hub. The on-line 'productivity dashboard' provides an opportunity to display the continuing processes for each work-package. This research project offers the observed opportunities created by the developed system. Future work will entail research experiments aimed towards system validation.

Data conversion refers to the process of extracting the data existing in the existing system, that is, the past data accumulated by the old information system or other methods and transferring it to the improved table of the new system. The person in charge of data conversion refers to the entire process of converting to the final destination table according to the rules designed/planned in advance. In most cases, data conversion design should be consider when the old system replace or the data of another existing system is converted and applied to a newly constructed information system. The goal of data conversion is to understand the current database system of operating environment, understand the characteristics of the DBMS in use, maintain the optimal database structure, and make the new system perform at its best. Data conversion methods are largely divide into a method using a tool and a conversion method using a program preparation. In this paper, we examine the advantages and disadvantages of the data conversion method, and try to derive the problems of the existing data conversion method. Based on this, an improved data conversion method for the system upgrade project was proposed, and verified through a questionnaire of an IT expert to prove its effectiveness

Recently, as Information System projects tend to be more complex, the importance of Information System Audit increases. In the same context, the need for the resident IS Audit also increases, which is supposed to deal with the possible risks and urgent issues by providing the appropriate support and timely coordination during IS project. Basically, for the effective IS Audit, the IS audit team members should be able to understand such a business context as work characteristics, business knowledge, goals, and culture of the organization. The audit team members should also be able to share the various knowledge of Information Technology and audit procedure with the owner of the project. Especially, for the resident audit, it is more important to fill the gaps in expertise between project owner and audit team. However, any studies on the need of common knowledge base (knowledge complementarities) in the IS audit have not been done so far. The purpose of this study is to analyze whether the knowledge complementarity based on inter-organizational communication between the project owner and audit team members makes an effect on the fidelity and performance of IS audit. In order to do this, the relationship among inter-organizational communication and knowledge complementarity, the fidelity of IS audit service, and performance of IS audit has been analyzed, using Structural Equation Model. The result shows that all the relationship is significant, which means that knowledge complementarity between the two different interest groups should be an effective factor on the fidelity and performance of IS audit. This result implies that, for better quality of IS Audit service, how to acquire the knowledge complementarity between the project owner and Audit team should be considered seriously as well as systematically in the process of IS Audit.

IT의 발전으로 산업사회가 정보화를 거쳐 지식화되면서 Value Chain을 규명하여 비효율적인 생산구조를 혁신하는 BPR(Business process Reengineering)이 이루어지고 이를 바탕으로 ERP(Enterprise Resource Planning) 구축이 이루어지고 있다. ERP를 확대하기 위해 SCM(Supply Chain Management)와 CRM(Customer Relationship Management)이 제조업에서 활발히 이루어지고 있다. 그러나, 건설산업에서는 이러한 IT의 접목이 본격화되지 못 하고 있으며 정보화에 대한 인식 또한 미비한 실정으로 정부 주도의 건설CALS와 일부 대기업에서만이 기존의 업무 프로세스를 개선하고 개별 시스템을 통합하는 작업이 이루어지고 있는 실정이다. 대다수의 건설관련 기업은 기존의 조직 및 생산구조에 대한 혁신이 이루어지지 않고 있는 실정이다. 건설산업의 특성상 사업수행 정보(Project Information)와 실적자료(Historical data)의 효율적 관리가 이루어져야 할 것이며, 기존의 기능 중심의 정보흐름을 프로젝트 중심의 정보흐름으로 전환할 수 있는 CIC(Computer Integrated Construction) 및 PMIS(Project Management Information System)의 개발이나 도입이 필요하다. 본 논문은 건설산업에서의 정보화의 문제점을 분석하고 정보의 발생과 흐름을 분석하여 정보화체계 구축의 핵심인 정보의 표준화·동시화·중앙집권화를 이룰 수 있는 방안을 제시하고자 한다.

It is critical to manage risks to complete IS(Information Systems) projects successfully. Identifying risk factors would be the first step for the project risk management. Previous research has discussed the issue with various points of view, such as different risk factors based on project types and roles involved in their projects. This paper empirically explored how people perceive different risk factors by project development methodology, between self-developing IS using programming language like C, Visual Basic and adapting software package already developed by software venders like ERP, CRM packages. There are researches regarding project risk factors for project management in the several point of views. And there are also researches regarding comparison between self-developing and adapting software packages methodology in IS project. However, there are no study on project risk factors comparison between self-developing IS using programming language and adapting software packages already developed by software venders in IS project. This research can be differentiated from previous ones, because it was considered both point of project risk management and development methodology in IS project. This research results implied meaningful messages to enterprise company to be planned IS projects and people who involved in IS projects. They should consider and need to prepare differently according to each development methodology for preventing project risks. It makes them reduce project risks in each case and complete successfully IS projects. Especially, if they have no experiences for implementing software packages, they can forecast the project risks and prepare them in advance.
