군사시설 건설사업의 설계변경 요인분석 및 개선방향

Abstract

Change orders have been widespread in both the private and public construction sectors. In particular, in the case ofG2B (Government to Business) contracts, adjustment of contract price and/or schedule extension is a frequentoccurrence due to change orders. To uncover the causes of change orders and suggest an appropriate strategy, thisstudy analyzed 296 cases of change orders in military facility construction projects from 2008 to 2010. The analysisrevealed that the major causes of change orders are users’ additional requirements (28.38%), a change of finishingmaterials (23.99%), and change of footing type (17.57%), in that order. Building on the results of this analysis, theauthors suggest plans for practical improvements. Specific recommendations include 1) reflect user requirements at theearly stage, 2) minimize the use of additional budget due to change orders, and 3) reduce the process and time forcontract amendment, among others. The results of this study may provide significant implications to those involved inmilitary construction projects, particularly project owners (i.e., the Ministry of Defense) and contractors.
