In Korea, a total of 15 airports including Gimpo Airport are in operation, and ○○ Airport Corporation operates and manages 14 airports except Incheon International Airport. Since most of these airports have been in operation for more than 30 years, constructions for remodeling are under way to meet increasing demand for air travel services and to upgrade outworn facilities.
The facilities of an airport are largely divided into those in the general area and the protected area, and workers who carry out various construction works as well as airplane passengers have to follow mandatory access procedures to enter a protected area. These security procedures are directly related to additional construction costs for construction companies because they were not expected at the time of contract and cause huge inconveniences for workers due to entrance procedure and work-hour delay. However, at present, there is little ground to adopt measures for correcting relevant issues including the reduction of work hours.
The purpose of this study is to analyze the decrease rate of work hours due to the procedure for entering a protected area by reviewing construction cases in major and medium-sized airports across the country. For the study, 3 major and 2 medium-sized airports were analyzed and a total of 17 construction cases (12 cases in protected areas and 5 cases in general areas) were selected.
The same entry procedure to a protected area is applied to and installed in major and medium-sized airports. The decrease rate of work hours was analyzed to be different in major and medium-sized airports. Based these analysis results, this study suggested the application of different decrease rate to major and medium-sized airports, respectively, when conducting a construction work in a protected area.
First, the decrease rate of work hours caused by the procedure for entering the protected areas in major airports was suggested to be 10% based on the result of comprehensive analysis of the time duration to get to a construction site after completing the entry procedure, assuming 8-hour (480 minutes) work hour per day.
Second, the decrease rate of work hours caused by the procedure for entering the protected area in medium-sized airports was suggested to be 5% based on the result of comprehensive analysis of the time duration to get to a construction site after completing the entry procedure, assuming 8-hour (480 minutes) work hour per day.
The result of the correlation analysis between the nominal variables for the difference between major airports and medium-sized airports showed the decrease rate of the working hour is highly related to the size of airports. It is indicated that the larger the size of an airport is, the longer it delays due to more distance to the construction site, but the number of workers and equipment appeared to be less relevant to the decrease rate.
The application of these decrease rates at the order stage of a construction in an airport protected area will ensure the reflection of the direct construction cost increase caused by the decrease of work hours for construction companies, resolve complaints of workers who enter the protected area and contribute to the enhancement of process and safety management when conducting a construction.
