Ministry of Land, Transportation and Maritime Affairs has implemented Construction CALS project for improving informationization level of construction industry and for making construction production system efficient. Although an importance of evaluation on level and performance of construction informationziation projects has been emerged, Construction CALS hasn't been evaluated so far. In this study, the performance indicators of construction CALS as the most important base in creating a performance management system were deduced. For this aim, this study reviewed the former researches on system construction for managing performance, analyzed current status of Construction CALS, arranged the relationship between upper strategies and ISP, developed pools of performance indicators, and this study followed IT BSC methodology. As a result, this study developed performance indicators of Construction CALS through four strategies such as globalization and activation of Construction CALS standards, research & development for reaching to international level in construction informationization technology, stabilization of system operation and distribution by publicizing Construction CALS and improving its functions, and policy implementation for managing and coordinating Construction CALS projects. These indicators will be applied to build a system of performance management.

정보시스템 개발 프로젝트는 다양한 리스크 요소로 인하여 많은 비용이 발생하는 구조를 가지고 있다. 일반적으로 정보시스템 소프트웨어 프로젝트가 납기 내에 성공적으로 이루어질 확률은 매우 낮아 프로젝트 실패를 막는 주요한 요인인 정형화된 비용에 대한 예측이 필요하다. 그러나 대부분의 프로젝트 규모 산정 시 산정 기준의 객관성이 부족하며, 프로젝트 수행 중 베이스라인의 관리가 제대로 이루어지지 않고 있는 실정이다. 이에 본 논문에서는 정보시스템 개발 프로젝트 초기에 현장에서 실용적이지 못한 기법의 한계를 극복하고자 방법론 기반으로 개발에 소요되는 공수를 산정하는 모델을 제안한다. 이러한 융복합적인 제안 모델을 통하여 정보시스템 개발 사업에서 소요되는 공수와 비용을 추정하는데 간단하게 활용할 수 있는 도구가 될 것으로 기대된다.

Remediation grouting has been widely used for the rehabilitation of various civil works like hydraulic and traffic structures. Recently there were some cases of remediation grouting for repairing old dams in korea. So this study will describe the case of remediation grouting of the concrete dam base located east-northern part of Seoul. We use Lugeon Test and Borehole Image Processing System(BIPS) for estimating the effectiveness of remediation grouting of this project. As the results of this study, we could find the lots of joints between the old concrete body and the weathered rock base. So the about 30% quantity of total cement grouts was injected at the boundary surface between concrete and rock base. And Lugeon Test and BIPS could be compared relatively because BIPS results could be presented quantitatively as well as qualitative analysis. Finally, we could find microfine cement was very effectively injected to the fine fissured concrete body compared with ordinary portland cement, but there was little injectability differences beteween microfine cement and ordinary portland cement at the large cracks or cavities were developed rock base.

The coordination and control of construction projects is vital if a project is to be a success. Almost all analysis has shown that these can only be achieved if good quality communication can be maintained on a construction site. This research focuses on the role that tablet computers could play in enhancing this communication. The following points are investigated in this paper: (a) Whether a tablet computer can enable users to monitor project progress more efficiently than traditional methods, (b) How the tablet computer fits within the project management iron triangle in construction, (c) The two different psychological impacts of information transmission for the end user using a tablet computer (i) The expectancy to transmit information frequently and rapidly from tablet computer users to project members whilst working onsite (ii) The mode of information transmission to the cognition of the transmitted information to the tablet computer. Through the use of structured interviews and questionnaires, the opinions of individuals within various disciplines in construction were canvassed. The approach adopted in this paper deals with understanding both the soft and hard issues for deploying such a system. This research enabled the authors to develop a base framework incorporating the key factors which are relevant for implementing a tablet computer based on information flows primarily.

Korean cadastral system keeps graphical maps made by the plane table method from 1910's. The fact is that the graphical maps grafted on paper cover about 95% of the whole land (MOGAHA, 1999). The needs are arising to transform the graphical cadastre to a digital one in compliance with modem technologies. Korean government has already digitise the old maps until last year. A nation-wide land information system, Parcel-based Land Information System, was established upon the digitised map database. However, the accuracy of the digitised coordinates hardly meet the citizens' needs because it cannot exceed that of the paper maps. The definite solution will be surveying all the parcels again and making new digital maps. However, commencing a project for resurveying 34 million parcels will require enormous amount of time and manpower. The strategy should be dividing the country into county-wise or grid-wise pieces and surveying one piece by one piece. Municipal governments of counties, cities or urban districts will be the propelling bodies of the project but the costs will hardly be affordable at a time. For the purpose of resolving the financial problem, each municipality can split its own project into smaller pieces by year base. There is accordingly a great possibility to create inconsistency over the divided project areas caused by different techniques applied, different equipments used and/or mismatches between the project borders. It provides some merits at the same time. The people in project completion areas will be satisfied with the enhanced accuracy and feel safe in land transaction and, in turn, soundly improves overall nation-wide economic situation. Therefore, the main issue of the thesis shows how to make the cadastral re-survey project scalable. Guidelines for how to perform the projects will be derived from a experienced case.

PMO(Project Management Office)는 IT 프로젝트의 성공적인 운영을 위한 보편적 접근방법으로 여겨지고 있다. PMO에 관한 선행연구는 PMO의 규범적 역할과 기능을 규명하는 데 집중하는 경향이 있다. 반면 실제 현장에서는 PMO가 발주기업과 전문PMO로 구성되는 조직간 협력체로서 운영되고 있기 때문에 적절한 협력체 (PMO 수행체계)의 수립은 프로젝트 성과에 의미있는 영향을 미칠 것으로 보인다. 본 연구에서는 발주기업과 외부 전문PMO의 역량이 PMO 수행체계의 수립을 통해 프로젝트 성과에 어떠한 영향을 미치는지 살펴보았다. 더불어, 발주자와 전문PMO 간의 지식 상호보완 정도에 따라 각각의 역량이 수행체계에 미치는 영향에 변화가 있는지도 살펴보았다. 연구결과, 발주기업과 외부 전문PMO의 역량이 PMO수행체계의 수립에 긍정적인 영향을 미치며 추진조직과 역할 및 책임에 대한 명확한 정의와 표준화된 프로세스의 확립 등이 IT 프로젝트의 성과에 중요한 요인임이 밝혀졌다. 또한, 발주기업과 전문PMO가 공통지식 기반을 갖고 지식 상호보완성을 확보했을 때 PMO가 더욱 효과적으로 기능을 발휘하는 것으로 밝혀졌다. 종합하면, IT 프로젝트의 성공을 위해서는 PMO 수행체계수립에서 거버넌스 관점의 접근이 중요하며 발주기업과 외부 전문 PMO 간의 지식 상호보완성의 확보가 도움이 되는 것으로 볼 수 있다.

OECD countries including Korea positively adopt performance-based budget systems which convert an input-centered system to an output-centered system to solve two baffling problems: public expense retrenchment and efficiency recovery of government management. Output management of IT project propelled in public sector becomes a prominent figure influenced by these keynote of policy. However, it is placed in difficult circumstances to develop a performance index and the methodology to cover characteristics of IT project, measuring the goal achievement of business and the customer contentment according to the phases of business progress. Existing studies of IT project accomplishment measurement have been fulfilled on the subject of business targeting on IT technology application, administrative information network business and national base of information network construction. Most of the studies have been executed using BSC or AHP to reflect synthetically business specifics of IT project from a methodological point of view. In this study, we propose a structural equation model (SEM) to develop a performance index which measures the outcome of IT project according to the phases of business progress, avoiding a simple presentation of project outcome or conceptual frame. The proposed SEM is applied to the survey results of "IT support project for Small and medium business". Based on the fitted model, we apply ACSI concept to develop an Information Technologization Success Index (ITSI). This index allows us comparison of several IT vendors as well as feedback information for further improvement.

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.

Effective cost management requires reliable cost estimates at every stage of project development. The primary purpose of this research is to develop systematic modeling procedures and an automatic computing program for infrastructure estimating in the Texas Department of Transportation (TxDOT). The computing system toggles between project input information and segregated district unit prices for highway work item quantity estimates associated with earthwork and landscape, subgrade treatments and base, surface courses and pavement, structures, miscellaneous construction, and lighting, signing, markings and signals. This quantity-based approach was chosen because of the conventional approach lacking of quantity information until primary design is complete.
