  • Construction projects have high potentials of claims among a variety of stakeholders. Claims on their own are not disputes but they have high potentials leading to disputes if agreements are not made between parties due to conflicting opinions. In the event of the construction disputes between clients and contractors, it could give negative impacts to both parties and, to minimize or pro-actively manage construction disputes, the role of clients is more significant. The objective of the study is to analyze a level of associations between the types of disputes and causes of construction projects based on the association rule analysis, and to identify and discuss key characteristics and implications from client's perspectives. The study analyzes associations between the types of disputes and causes, and also identifies those with a high level of associations. It also presents the outcomes of more systematic analysis compared to descriptive statistics just based on frequencies. Through the analysis of the data cases, the study proposes the directions to resolve the causes of disputes from client's perspectives. It can assist to improve understandings of the relationships between the types of disputes and causes and to pro-actively manage the disputes of construction projects.

  • To enlarge the international competition and construction productivity, the domestic construction market attracts the private capital and expands the facility of :iocial Overhead Capital(SOC). However, the application of the business system used at the public project didn't utilize the effect of social overhead capital. It caused problems that parties' business was inefficient and their allotment of the risk was inadequate. This paper presents the course to reorganize the business system which the coincides with the origin aim of the SOC. For the reformation of the supervisor's work scope and business system and the government's overall project management, in other words, this paper proposes the professional organization to replace the superintendence and the formation of optimal business system. This paper confirms the privity of contract among parties of SOC project and parties' work scope and system between relative laws and concession agreement that government made a contract with Special purpose Company (SPC).

  • In general, defects cause a lot of maintenance costs and serious damage to various stakeholders, such as the owners, contractors or occupants of apartments. For this reason, a systematic and efficient defect management method is needed to minimize defect disputes. This paper derives a defect classification framework and proposes a defect risk assessment model for different types of defects. For this purpose, 6,000 defect items are allocated to the defect classification framework; these items are associated with 34 apartment projects over ten years old. As a result of this analysis, it was confirmed that the defect risks are concentrated in the areas of RC and finishing work. Based on these results, it is necessary to prevent the major risks of defects according to their priority. Based on this research, it is judged that further research to develop a method of managing the risks of defects may be necessary.

  • The government abolished the existing method to calculate the construction price by the quantity take-off and pricing. It has introduced a new estimating system which uses the actual cost data on the basis of actual contract unit price. However, in the case of the current method to calculate the estimate price of BTL educational facilities, it is difficult to prepare an accurate ground for calculating unit prices due to a lack of standardized work breakdown structure (WBS) and guidelines for the detailed bidding documents. Thus, this research aims to establish WBS using the actual construction price on the basis of the actual bidding documents for the previous construction of BTL educational facilities. This specific WBS can be differentiated from the general WBS which is not suited for construction of the educational facility. It makes possible to build the construction information classification system and it helps to systemize the maintenance and repair cost items.

  • Public construction projects need complex and multi-functional management skill, since the most of public construction projects are comprised of multi-project and mega-projects. In order to effectively manage construction projects, PMIS is widely used. However the majority of the current PMIS have been developed as a single project-oriented business management system. Thus compatibility problems are encountered during the process of integrating the entire systems to manage the multi-complex projects. In addition, the form of orders applying BIM are increased recently, but the research and development of BIM based PMIS are still lacking. In this study, therefore, the functions of PMIS main objectives based on the analysis of PMIS As-Is and To-Be of PMIS, the dual management system utilizing Internet and Intranet will be proposed to integrate the individual PMIS with Integrated Program Management System. Rather than combining commercial BIM tool and PMIS directly, which is the common method of failure, the sequential process model to adopt BIM based PMIS is also explained. Step-by-step development method of BIM based PMIS is suggested to prepare for the activation of BIM technology in the nearest future.

  • The post-evaluation system after construction projects can evaluate estimates of use demand, project cost, and project schedule estimated in the planning phase of construction projects in public sector. Thus, it was introduced in 2000 for the purpose of reduction in future errors during similar constructions by project orderer by referring the post-evaluation results. However, many barriers to the post-evaluation system after construction projects have been reported due to evaluation systems that lack objectivity and reliability and lack of main bodies that utilize the system. Thus, this study derived implications for improvements of the post-evaluation system in Korea by benchmarking building project evaluation system and management as well as utilization systems of developed nations. Then this study conducted a survey with experts who have experienced activities in the post-evaluation committee and members of post-evaluation for public project owners. Therefore it identified the need of installation of specialized post-evaluation institutions as well as functions and work tasks to be taken by specialized institutions. Based on the analysis results, this paper provided revision drafts of related legislations and guidelines to be effective in post-evaluation. Through the study results, many trial and errors can be reduced in similar projects in the future by performing in-depth analysis on large-scale construction projects and repeatedly applied building project practices can be improved to raise technical competitiveness if the specialized institution is installed.

  • In spite of advantage by using BIM as quantity take-off, schedule control and clash check, absence of guidelines is a barrier to applying BIM to road domain. In this research, domestic and overseas cases of BIM guideline are analyzed in order to develop the road BIM deliverable submission system. The analysis is classified 5 topics which are BIM submit product list, submit files format, availability of existing 2D based products, BIM authoring tools and submit process. As a result, It needs a lot of effort to standardize BIM delivery system for road domain because BIM submit product list and BIM authoring tools are changable depending on BIM use cases. However, submit files format and submit process are common part to suggest guidelines of road BIM delivery system. It requires to combine BIM and 2D products for road BIM delivery system because delivery products are not exactly alternative 2D based delivery products for the present. The authors expect this research to use as basic data for development of the BIM deliverable submission system in road domain.

  • The importance of information management has been emphasized in Korean construction industry, Both public and private have invested to establish and operate construction CALS, construction management (CM), computer integrated construction(CIC), and earned value management system(EVMS). A standard construction information classification system is essential to operate the systems mentioned above. Therefore, Korean government released Integrated Construction Information Classification System(ICICS) in 2001. However, the ICICS is not widely used in construction due to: 1) difficulty of changing existing system, 2) insufficient publicity of the ICICS, and 3) no legal binding force. Especially, participants in construction do not recognize applicability of the ICICS. This research surveyed the degree of recognition and utilization of the ICICS. This survey includes both customized classification systems used by companies and the ICICS and investigates the degree of utilization and drawbacks. The results show some construction companies use their own classification systems and the others use the ICICS prepared by the government. Furthermore, the degree of recognition is in sufficient. The degree of use in design management, specifications, cost and schedule management is very limited. The publicity and education are critical to induce the utilization of the ICICS. The necessity of revision was recommended based on pilot project study that is performed to measure the degree of application of ICICS on the projects. Therefore, this research proposes the measurement model for information application and analyzes the degree of utilization of the ICICS in different phases of construction.

  • Purpose: It is expected that various infrastructures diagnosis equipment will be needed as infrastructures management is strengthened to implement the Framework Act on Sustainable Infrastructure Management. It is necessary for a certification system to supply certified products of a reasonable level in accordance with market requirements for various convergence equipment. This paper deals with the introduction of certification system of inspection and diagnosis equipment for infrastructure using advanced technologies. Method: The basic elements, systems and procedures of certification system were reviewed through analyzing and comparing the existing similar certification system in Korea. In addition, a survey was conducted on a catalog method and the minimum performance criterion (sampling survey and complete enumeration survey) to equipment developers (manufacturers), clients and equipment users. Result: This survey showed that clients preferred complete enumeration method on the basis of minimum performance, and equipment users also preferred complete enumeration survey and sample survey, for minimum performance, at a similar rate. On the other hand, equipment developers preferred the catalog method. Conclusion: Clients and users who are the users of the diagnostic equipment preferred the minimum performance criterion because their trust in quality is important. On the other hand, developers(manufacturers) preferred the catalog method which adopts self certification because it is regulated in developing various products. There is no specific plan for the minimum performance standards required for the introduction of the method which users demand, at present. In addition, it is not desirable to force to introduce a certification system because it requires a considerable period of study to prepare the specific standards. Therefore, it is appropriate to operate the system for a certain period of time centering around the catalog method for the stable and continuous development of the infrastructure diagnosis and test equipment market in Korea. Also, it is effective to expand and develop the certification system to the extent that it minimizes the impact on the market when specific plans for the standards are prepared in the future.
