Despite the significant increase of Korean contractors in the international construction market, many SMCCs (Small & Medium Construction Companies) have suffered in the global financial crisis, and some of them have been kicked out of the international market after experiencing huge losses on projects. SMCCs face obstacles in the international market, such as an insufficient ability to gather information and inappropriate management of associated risks, which lead to difficulties in establishing effective business strategies. In other words, making immature decisions without an effective business strategy may cause not only the failure of one project but also the bankruptcy of the SMCC. To overcome this, the research presented herein aims to propose a decision support system for SMCCs, which would screen projects and make a go/no-go decision at the early stages of international projects. The proposed system comprises a double axis: (1) a profit prediction model, which evaluates 10 project properties using an objective methodology based on a historical project performance database and roughly suggests expected profit rate, and (2) a feasibility assessment model, which evaluates 17 project environment factors in a subjective and quantitative methodology based on experience and supervision. Finally, a web-based system is established to enhance the practical usability, which is expected to be a good reference for inexperienced SMCCs to make proper decisions and establish effective business strategies.

As a knowledge-based economy is emerging, knowledge management (KM) is being rapidly disseminated in both academic circles and the business world. Accordingly, how to effectively manage knowledge is vital to the survival and advance of a company, particularly in project-based industries such as construction. For these reasons, construction companies have adopted IT-based Knowledge management systems (KMS), which is the technology platform and infrastructure that an organization employs to support knowledge management. However, many construction companies have spent resources on developing a KMS that only focus on codification. Furthermore, small and medium-sized companies have limited resources to afford extensive investments. This research addresses the problems found in the current KMS and develops a web-based construction knowledge management portal (CKMP). To achieve these objectives, a case study is conducted and requirements for implementing KM are identified. Based on the identified requirements, this paper builds CKMP using Expert Index (EI), blog, ontology based knowledge retrieval, and wikiblog. The most important functionality of CKMP is their fundamentals to synchronize and support KM process. In order to validate the CKMP, a pilot test with actual users is conducted, and the usability of the system is compared with the current systems. This study is relevant to both the construction industry and academia, as it provides a means of enhancing the performance of KM.

최근 건설 프로젝트의 효율적인 관리를 위해 현장에서 각 사업주체(발주, 설계, 감리, 시공, 협력업체)간 원활한 의사소통, 협업, 정보공유 및 교환을 위하여 사업관리시스템인 PMIS(Project Management Information System)를 많이 사용하고 있다. 그러나 이러한 개별 프로젝트단위로의 시스템 개발은 회사 전체 프로젝트관리 효율성 및 통합화에 저해요인으로 지적되고 있다. 이는 프로젝트단위로 개발되는 사업관리시스템의 특성상 전사차원의 시스템개발 및 보급을 위한 Master Plan인 ISP(Information Strategy Plan) 즉 정보화 전략의 수립의 부재에 기인한다고 볼 수 있다. 본 논문은 실제 대형 건설회사인 국내 D건설사의 PMIS구축을 위한 정보화전략계획(ISP) 수립방법 및 절차의 사례를 소개하고 전사 PMIS구조, 전사업무프로세스 개선과 시스템 구축방법 및 성공요소 등을 제시한 논문이다. 이 연구 논문을 통해 향후 건설회사의 사업관리 시스템 구축 시 효율적인 PMIS개발과 최적화시스템을 구축에 도움이 되고 정보화 전략계획 수립에 활용 할 수 있기를 기대한다.

The farming type in Korea is predominantly a small farm managed by family members. This study mainly examines the current usage of the website of family farms as a management tool for small farm business and discusses the strategies for effective utilization of the website. A county that currently employs governmental project of information system was purposely selected. Among all the websites operated by small farm businesses in that county, websites of which purpose is introduction of the business, advertisement, or e-business were included for analysis; it yielded total seven websites, The study was conducted with two phases; on-line website analysis and interview with business owners. The websites were analyzed based on four categories; content, interface, design, and site management. With regard to the content of the websites, the lack of connection between domain names and product names was found. Moreover, the problem relevant to site management was shown as low utilization of bulletin boards and delayed upload of new information. However, design and interface were comparatively well presented. Business owners reported that the motivation to initiate the websites was mostly supports from the governmental project for the agricultural information system. The barriers to effective management of websites were found i) business owner's misinterpretation of business website with e-business ii) very limited opportunity for website management education in small farm business, and iii) lack of regional infrastructure for information system. Based on the findings, this study suggests as followed; i) construction of infrastructure should be preceded to make effective management for websites; ii) education for website management should include small business management strategies as well as computer skills, iii) the education should be provided in diverse ways considering subject's characteristics iv) small farm business owners should be informed that their websites could play a role only to provide information about the products and hand over the practical load for e-business to retailing web sites such as portal shopping mall; and v) wives' participation should be encouraged.

공정 및 작업단위등이 다양하고 복잡한 건설산업에서 작업일보의 관리는 매우 중요하다. 그러나 건설산업 분야의 다양한 건설프로젝트 관리 시스템은 작업 및 작업시 발생하는 정보들을 효율적으로 관리하지 못할 뿐만 아니라 하수급업체와의 연계가 되지 않아 실제적으로 이용되지 못하고 있다. 이것은 하수급업체에 대한 배려 없이 원수급업체 주도로 시스템이 구축/이용되기 때문이다. 이러한 이유로 하수급업체 중심의 시스템이 발전하지 못할 뿐만 아니라 프로젝트 진행에 있어서 발생하는 작업정보의 축적에 있어 누락 및 왜곡이 발생하는 문제점이 발생하고 있다. 따라서 본 논문의 목적은 웹을 기반으로 원수급업체와 하수급업체간 원활한 작업정보 관리 시스템의 개발에 관해 연구/분석하고 모델을 제시하는데 있다.

Construction documents are recognized as an essential component for making a decision and supporting on construction processes. In construction, the management of project document is a complex process due to different factors such as document types, stakeholder involvement, document flow, and document flow processes. Therefore, inappropriate management of project documents can cause several impacts on construction work processes such as delay or poor quality of work. Several information and communication technologies (ICT) were proposed to overcome problems concerning document management practice in construction projects. However, the adoption of ICT may have some limitation on the compatibility of specific document workflow. Lack of understanding on designing document system may cause many problems during the use and implementation phase. Thus, this paper proposes the framework that integrates Soft System Methodology (SSM) concept and Integrated Definition Modeling Technique (IDEF) for analyzing document management system in construction project. Research methodology is classified as the case study. Five main construction building projects are selected as case studies. The qualitative data related to problems and processes are collected by interviewing construction project participants such as main contractors, owners, consultants, and designers. The findings from case study show the benefits of using SSM and IDEF. The use of SSM can help identify the problems in managing construction document in rich picture view whereas IDEF can illustrate the document flow in construction project in details. In addition, the idea of integrating these two concepts can be used to identify the root causes of process problems at the information level. As the results, this idea can be applied to analyze and design web-based document management system in the future.
