Abstract: In general, Change Orders in construction projects pose a serious problem possibly impacting quality, cost, and time of the projects. Youth Sport Center Construction Project (YSCCP) in Egypt as an example of the sports construction industry have faced quit a number of Change Orders leading to cost increae and time extensions. (9) Groups of youth sport center construction projects experienced (151) Change Orders. These groups of projects were utilized to contemplate different causes of Change Orders, the frequency of their occurrence, the responsible of this Change Order, the cost of Change Orders, and the time extension attributed to these Change Orders. This issue was analyzed to measure the reasons and effects of change orders. This paper presents the relationship between project cost and construction time within construction projects. This paper presents a time-cost relationship model valid for Youth Sport Center construction project. The model included Change Orders categories; Work disciplines (Civil work, Electrical work, Structural work, Architectural work) and Project parties (Owner, Consultant, Contractor, Local Authorities).
