Purpose: Change orders have long been an inherent part of the construction industry around the world and especially in Gaza Strip where construction projects suffers from variation orders. These variation orders are high especially in Qatar projects. This research investigates the main causes of variation order (VO) in worldwide projects through the literature and conclude which of them are affecting locally. Aim and Objectives: The aim of this research is to improve the control on variation order issue to the minimum in construction projects in Gaza Strip. To achieve the aim of this research many objectives exist, these objectives can be summarized as to investigate the factors causing variation order from the literature, extracting real causes of variation order through analyzing a case study of one of the completed projects of Qatar projects, and propose appropriate solutions to decrease the variation orders to minimum as much as possible. Methodology: First, review the literature to extract the causes of variation order around the world and then determine which of them is applicable in Gaza Strip. This was fulfilled using questionnaire and case study. A questionnaire will be developed to assess the perception of owners, consultants, and contractors on the factors causing variation orders in the construction industry in Gaza Strip especially the Qatar projects. Finally, a case study on one of the finished projects of Qatar projects to compare the real causes of VO with the result from analyzing the questionnaire. Results: The most influential factors causing VO are change of schedule by owner, design complexity and difficulty to understand, lack of contractor’s involvement in design, delays in secure site, equipment or materials, and site safety considerations Conclusions: It was concluded that there are some similarities and differences between real data and questionnaire result. The differences between the study and real data is mainly because the study of the completed project has a special nature where this project faced several difficulties such as war and closure of the crossings. Not to forget to mention that the study included two projects (roads and buildings) but the case study included only road project which certainly caused differences in factors causing variation orders between the study and the real data.
