The purpose of this study is to derive the risk factors that occurred during the construction of the temporary aircraft runway and to analyse the risk costs and loss costs. For this purpose, actual construction data made during the construction of the aircraft runway were investigated. And the risk factors that occurred during the construction work were derived. So the increased construction costs and loss costs due to risk factors were analyzed. The results of this study are as follows: 1)The number of risk factors that occurred during the construction of the aircraft runway was derived from eight. 2)It was calculated that the total risk cost of 5.2million won, the risk cost of the owner's should be 243 million won and the cost of the contractor should be 277million won. 3)Owner's was up 2.36% from its planned budget and the contractor lost -277million won out of its planned profit of 443million won, resulting in a residual profit of 165million won. The results of the study are used as a reference for estimating risk factors and contingency that should be considered in aircraft runway construction.

In this paper, we propose a secure alternative for improving airspace capacity of Incheon International Airport. Since the direction of simultaneous independent approaches to runway 15/16 radar-guided approach for ILS approach procedures for the need to provide control services, in view of the radar is the smallest possible no-fly zone airspace propose the demilitarized zone (P-518) adjustment. If possible simultaneous independent approaches to secure a temporary increase in the holding area due to traffic, the military training airspace gradually secured a total of 10 miles by 5 miles, some military training airspace in Osan Approach Control is proposed to include in Seoul Approach Control.
