A major problem in construction projects is variation orders. The goals of this work are to identify the factors responsible for this and to examine its effects on roadway construction projects in south of Iran. Review of previous works on this subject has been limited to developments since the year 2000. In order to obtain the view of many players such as employers, consultants and contractors in the industry on these phenomena, a survey was conducted using a questionnaire. This study was able to isolate 10 critical causes of changes in orders out of as many as 26 causes. It was concluded that change of plans or scope by employer, errors and omissions in design, differing site conditions and contractor's financial difficulties were some of the critical factors causing variation orders in roadway construction projects. Cost and time factors constituted the most visible consequences of variation orders in construction projects. These findings seem to agreewith the view of experienced specialists. However, this study is confined to roadway construction projects on south of Iran, nevertheless, the results of construction management problems is common within the developing countries.
