    abstract = {This study aims to assess risks caused by variation orders in construction projects in Egypt, through
studying the most important causes of the variation orders in construction projects. A structured questionnaire
was developed which contained 39 collected causes of change and categorized depending on the origin of the
variation, owner related, consultant related, contractor related, project management related or other related
variations. The survey was carried out among client representatives, consultants, contractors and project
managers involved in delivering projects. A total of 153 received questionnaire sets out of 250 questionnaires
distributed. The collected questionnaires were analyzed with Statistical Package for the Social Science “SPSS”.
The risk of each factor was analyzed by four different methods. The results of the study show that the most
five risky causes of variation orders are “Change in economic conditions”, “Lack of coordination between the
parties”, “Bad sub-contractor or supplier by the contractor”, “Impediment to prompt decision-making process
by the owner of the project” and “Contractor’s financial difficulties”.}
