Recent research has been ongoing for modular buildings in the country and interest increases. However, the activation of modular building projects is obstructed in the construction industry. There are many reasons to identity for this obstruction but one issue should be focussed. Modular buildings require to change the existing construction production system to a new construction production system, which is factory production - transportation - erection. However, the existing project delivery system in the public sector could not be adapted for this new construction production system due to the obligation of multi prime contract use, such as electrical, communication, fire fighting contracts by Law. Therefore, modular buildings in the existing project delivery system are separately contracted by multi prime contracts and modular units composed of the buildings are contracted by an architectural prime contractor as a commodity. As results, construction costs are increased, potential quality problems are raised and the existing project delivery system is finally an obstacle not to maximize benefits of the modular buildings. In this paper, we propose a new project delivery system for the modular buildings to adapt then ew construction production system.

These days, Construction industries are getting bigger, more specialized and complicated. Accordingly, the items of management is increased, also owner's organization is reduced. For this reason, various a method of construction management is introduced in the domestic construction industry. But introduction of construction management have caused increase cost because role duplication of managers. This role duplication is caused by confusion of trial and error, irrationality of system. And every construction project have peculiar properties, also owner's organization of project have various properties. This various properties is not reflected in the construction management , and the regimental method of construction management applied. In order to solving these problems, this study suggested the commissioning model for CM service reflected the properties of project and owner. This study have to selection of the critical service, service item of construction management and definition of owner's role through analysis of the properties of project, owner's capacity and requirement.

On March, 2013, the Government announced the Multiple Prime Contract method will be expanded in public building construction projects. The applying multiple prime contract method has been immersing issue among all stakeholders of construction project. The owner conducts the role of a general contactor as well as owner's original responsibility while construction works being executed by specialty contractors. If the owner has not experience of project management, it should be bring about increasing management cost due to the interface problems among prime contractors. With this reason, it is difficult to administrate the multiple prime contract. So far there has been no methodology of predicting management cost in the multiple prime contract. Therefore, this study aims to enable the operation of efficient multiple prime contracts by developing a model to predict their management costs.

The Domestic Construction Industry is in the process of changing from a one-sided production method centered on the contractor to a production method in which the order and the contractor can collaborate. Depending on the delivery method, the bid/success method, the contract method, and the degree of business involvement of the order may also vary. In this thesis, in order to introduce 'Construction Management at Risk' suitable for the domestic environment, domestic and foreign institutional analysis, bid process analysis, contract fulfillment and management analysis, post management analysis, and related laws and regulations for legalization In order to suggest a plan for the efficient operation of the system, a system and case analysis of domestic and international construction responsibility type construction project management was conducted. 'Construction Responsible Construction Project Management' defined in the Framework Act on the Construction Industry is divided into the main contract transfer contract, which is a service contract performing pre-con work, and the main contract, which is construction project management and construction contract. Therefore 'Construction Management at Risk' should be regarded as one of the ordering methods rather than a successful bid system, as in the case of overseas, and legalization as a bidding system equivalent to design/construction batch bid and technology proposal is necessary for introduction. In order to introduce 'Construction Management at Risk' suitable for the domestic environment, domestic and foreign institutional analysis, bidding process analysis, contract fulfillment and management analysis, and follow-up management analysis are conducted. A method for efficient operation was suggested so that it can be applied in the domestic market while maintaining the original merits of this system.

Recently, the Design-Build (DB) delivery method in public sector makes some argument by reason of the initial cost which is more higher than those of Design-Bid-Build (DBB). According to the results of pervious researches related to the performance evaluation of delivery method, DB can lead the reduction of project cycle time and also is superior to the traditional DBB in terms of construction quality. The performance on each delivery method could be generally evaluated by a project cost and a project cycle time as one of quantitative analyses, and also by construction quality as one of qualitative analyses. In most researches, the evaluation of performance level based on delivery methods has been evaluated by the degree of their satisfaction through the interview with owners. Therefore, this paper analyzed the design documents of construction projects delivered by traditional DBB and DB in bridge construction projects in order to measure design quality, constructability, maintainability, and etc. As an above-mentioned analyses, finally, this research shown that how much the difference of performance level is by each delivery method.

It has been 10 years Since December 1996 when CM method was institutionalized by Construction Industry Fundamental law. Even though construction market has been in stagnant of business activities till now, CM in Korea started to be activated by the introduction of CM method i.n public construction. In the end of 2005, the number of CM order's contract is 6.7 times , an amount of CM order's money is 9.2 times more than operation plan of CM system announced in 2001. Therefore, CM market has been dramatically growing. However, it is judged that the shortage of faith in CM project and necessity of CM method are not recognized and study on a owner who affects successful settlement of CM has not been performed. When considering those points, in introduction and practical use of CM, CM is suggested to the field which is necessary for a client through the task performance level research and analysis of a owner who act a important role to activate Construction Management. As result of studying pre-existing papers to i.nvestigate of owner's capability level, the task function of a client is classified into 10 types and a public opinion poll was performed based on the 10 types of function.
