This study analyzes the present public construction ordering system focussing on the legal framework for the fire facilities construction business and investigates the problem of subcontracting, and further reviews why Separate Prime Contracting should be recommended in policy, social, legislative and regulative terms. This study suggests the amendment of Fire Facilities Construction Business Act, with new bill drafting. The result of this study shows the present public construction ordering system has huge disparities between main building construction business and fire facilities construction business, and recommend Separate Prime Contracting should be adopted in the fields of fire facilities construction business. The system of Separate Prime Contracting may secure business entities' responsibility and higher quality of fire facilities, and also result in reasonable construction practices in reasonable costs. This system may also contribute to improve public safety level in fire facilities construction.

Since the Construction Management(CM) was introduced into the Korea construction industry, the efforts for acceleration of CM adaption have been continued. The fact that an owner organization has the essential key to successful application of CM delivery method is true, but there has been no study on owner's organization. An owner should decide their organization type and measure their current needs of each CM business functions for successful application of CM. After the needs of CM business functions are measured, the owner should reinforce their required business functions through strengthening their in-house capability or outsourcing. Thus, this paper defines four kinds of owner organization type and suggest the form for evaluation of owner's CM ability and analyze about needs of each type's CM ability through making up question.

Exemplary contracts of construction management (CM) including highway projects have been carried out in the civil engineering area over the past ten years. However, practical and administrative challenges as transitional circumstances have been revealed in the different participants of supervision, inspection and construction management. Thus, it is important to internally overcome problems and negative perception encountered in civil engineering, and to promote the efficiencies in construction cost and quality. In addition, external efforts should be put to market opening, globalization, and technology development for competitiveness and high value industry. While it is critical to establish the concrete CM system by collaborating with various participants, proven architecture and system have not been provided because of incorrect measurement of CM accomplishment, overlap of responsibility between CM and supervision, and slow deployment in construction field. This paper analyzed the current CM practices and business environments, and presented the possible solutions for strategy improvement of CM in the owner's view point.

This is a study on the ordering status of the cultural property repair work in Seoul, centered on the cultural property construction orders from each local government and affiliated institutions. The scope of this study is spatially based on the city of Seoul. The time range is from October 2015 to September 2017. We can grasp the scale of the cultural asset construction by recognizing the status of the cultural asset of the city and the budget available for repairing the cultural asset. By analyzing the actual situation of the cultural property construction over two years, we were able to learn the total number of orders, the ordering period, the order size and the associated order type. By analyzing the detailed data, we could grasp the actual state of each cultural property type mixing. As a result of that, it was found that one cultural property corporation had difficulty completing construction without the involvement of other types. This suggested the better contract way to a cultural property construction. This study suggests an appropriate ordering method analyzing the tendency of construction orders of cultural properties, which can be utilized as basic data for the placement of cultural property repair technicians in the field. In particular, landscape architecture is an important aspect of the cultural property construction. Despite the need to establish the status of landscaping, there are no papers describing the actual status of contract way to a cultural property construction and the status of the landscape architecture associated with them. This paper empirically reveals the facts for Seoul, and then makes a proposal to establish a complete analysis of the landscape construction business. Specifically, landscape architecture is in a position to take responsibility for the landscape of cultural asset. It is possible to propose the establishment of the status of landscape architecture and to contribute to the securing of business areas that are part of repairing cultural properties.

According to previous research, the reason why Design-Build(hereinafter "DB") outperforms Design-Bid-Build(hereinafter "DBB") in terms of cost is due to less change orders(hereinafter "COs"). However, if biddropping was low for DBB resulting into increasing COs, then it would be wrong to conclude that DB is superior due to less COs. Therefore, in order to confirm such misjudgment, the attempt to comprehensively analyze biddropping, COs and delivery method was made as previous methods had analyzed either the relationship between delivery method and COs, or biddropping and COs. This research uses path analysis, which simultaneously compares effect sizes on COs according to delivery method and biddropping based on the project type, and validated the mediator effect. The research proved that DB outperforms DBB due to less COs cannot be validated as biddropping caused a mediator effect by intervening between the delivery method and COs for specific project types. Therefore, the mechanism of delivery method acts on COs through biddropping was established. Also, the identity of biddropping was investigated in a different perspective from previous research. Based on this result, this research is expected to help determine a delivery method by considering the mediator effect of specific projects and evaluate performance.
