  • All of the partner must manage continually scheduling for the successful project in construction. Besides, that is not a important only contracter's managing but also owner's managing which is a very important about project finishing in time. Especially, in the case of mega project, the owner has to manage progress of scheduling to control contractor. And the case of progress to delay or to change, owner, contractor, and inspector must make a plan of recovery scheduling. This study proposes a construction process model from IDEF Methodology.

  • The organic law on the Construction Industry, initially, this law was enacted with a view to preserving and fostering the specialty of each type of industry. By dividing each construction business boundary, it gradually settles the system of construction specialized on the basis of productive stages. Controversy over the abolishing regulations on business boundary still continues to swirl. Since the intensity of exclusion as well as rigidities become increased. This results from the fact that informations are not shared among business boundary and businesses under the protection of the business boundary regulations choose 'rent-sicking activity'. According to dissidents against this law, structure should be established not by artificially enforced institution but by voluntary efforts of participants in construction industry. This paper aims at improving the competitive of the construction industry by showing the efficient system of construction and proving the legitimacy of abolishing business boundary

  • Recently, many companies recognize the individual human resource as a core asset of the corporate value creation and devote a lot of effort to develop and manage competency-based human resource in order to strengthen the corporate competitiveness. As the integrated construction company taking the major portion in Korean construction industry, its construction engineers perform the construction supervision task with various related parties at each stage of the life cycle of the construction project. Therefore, the competency of a construction engineer is an important factor which have a direct impact on the success of the construction project. However, the current capability evaluation scheme of the domestic construction engineers is mainly oriented on the qualification factors such as the certificates or the seniority and this is quite different from evaluating the actual ability for construction management tasks. In this point of view, this study proposes the appropriate level of proficiency in cost management by analyzing the work process and its detailed items of the cost management that is the one of the basic management items of the construction industry. Based on this, this study analyzes the current competency level of the construction engineer by comparing with the required competency of each job position and also performs the engineer's work competency analysis of each work step.

  • Building construction projects are performed by a number of sub-contractors specialized in diverse trades. Therefore information management among these constituents is quite challenging especially due to exponentially increasing manpower and material resources. In recognition of the importance of information management in project sites a number of systems have been suggested, but the application is limited one of the main reason is that general contractors use these systems and sub-contractor's participation understanding and financial ability are limited. Besides other problems such as loss along communication channel, distortion of information due to inefficient input device and tremendous amount of time and labor are required for collection analysis, and management of information to prepare a daily-report. Therefore the Purpose of this study is to improve reporting process through analyzing current daily reporting system. This paper also suggests the direction of the improved daily reporting system to enhance the performance of construction projects through incorporating sub-contractor's participation in daily reporting system.

  • Recently, Design-build project as delivery system public construction sector tends to be increased according to the Masterplan for promotion of construction technologies, and construction projects are increasing their complexity, variety and scale. And owner's requirements become various. Preliminary design for design eligibility judging of design-build has been designed excessively to get a good point and this tendency includes the elements which is capable of wasting the budget. Because of excessive design, owners require to apply VE study into the design development phase but in the Design-build system, VE application has not been of no effect that owners expect, owing to the characters of lum-sum contracts. The purpose of this study is to propose the plan for effective application of VE in the design development phase in order to solve the problems such as excessive design of preliminary design in the design-build project. This study established plans for VE application through investigating and analyzing VE application case and then proposed the applications in the aspect of regulations and contracts, parties participated in project, VE operation through research for verification of usefulness.

  • In the construction industry, projects are becoming increasingly large and complex, involving multiple subcontractors. Traditional centralized coordination techniques used by the general contractors become less effective as subcontractors perform most work and provide their own resources. When subcontractors cannot provide enough resources, they hinder their own performance as well as that of other subcontractors and ultimately the entire project. Thus, construction projects need a new distributed coordination approach wherein all of the concerned subcontractors can reschedule a project dynamically. To enable the new distributed coordination of project schedule changes, I developed a novel agent-based compensatory negotiation methodology, which allows software agents to simulate negotiations on behalf of their human subcontractors. This research formalizes the necessary steps that would help construction project participants to increase the efficiency of their resource use, which in turn will enhance successful completions of whole projects.

  • The current PF project is entirely relying on construction company's credibility. As such, it has increased a negative and bad recognition in domestic real estate economy. In addition, PF experts has a perception that a project's safety of future cash flow profitability is more important than the construction company's credibility. So many PF experts make an effort in order to set aside safe project structure of PF and analyse systematically the risks of the project. In common feasibility study of the PF Project, financial specialists and real estate specialists are forecasting and evaluating the suitability of the project through reviewing the development profit from the project of sales. However, cash flow analysis and evaluation from the perspective of mid-sized construction companies are still in the primary level. Therefore, this study has analysed the current feasibility study and go/no go decision making procedures. Then the authors have a new cash flow analysis method from the perspective of mid-sized construction companies, by improving the feasibility study and go/no go decision making procedures.

  • Korea's overseas construction industry has been rather depressed by the weakened profitability as well as the sharp decrease of the market shares due to the lack of international competitiveness and the declined international market. There exist a lot of various risks in performing the overseas construction, and especially EPC projects, which entail complicated process from different parts, also require a sophisticated procurement and management skill. Subsequently, to survive in the competitive international market, we need to establish strategies to select potentially profitable projects at the initial stage of bidding process and to mitigate the high degree of risk exposure through contract negotiation and its adjustment. This research discusses the trend of environment in international construction markets. Then, it identifies the key factors that affect the profitability significantly through the structured surveys from 59 actual overseas projects, and it analyzes the key factors by using statistical methods. This research provides the profitability evaluation bases, with which overseas construction participants can forecast and analyze the risk more systematically, by eliciting profit-influencing factors using the result of statistical analysis, literature review and structuring their cause-and-effect relationships. The profitability casual hierarchy structure describes the profitability factors' hierarchy in details and their interrelationships. It also enables us to find out critical factors directly related to profitability aggravation through a qualitative and quantitative analysis. Ultimately, with this hierarchy structure as the base, the research will suggest how to develop the quantitative profitability forecasting model.

  • The public housing needs maintenance administration for improvement and retainment of residential condition by means of tenants participation. However, most researchers have considered tenants as passive participants in this context. The previous studies did not comprehend perspective of tenants participation and just measured the management preference and the level of satisfaction on maintenance. This study investigates the attitudes and perceptions of tenants on participation in public housing maintenance by introduced Q method that provides a systematic and rigorous quantitative means for examining human subjectivity. The subjectivity is classified as types according to cost and benefit factors by principal components analysis and varimax rotation of the extracted factors. As a result, this study present 5 types of tenants participation and expect to discuss desirable roles of tenant and org anization in public housing maintenance.
