This research highlights the impact of Variation Orders in construction projects, especially in the Tenjoresmi Area Arrangement. The results of the field study showed that the Variation Order caused significant changes to the Cost Budget Plan (RAB) and the performance of the implementing contractor. Some of the work affected includes changing the brand of air conditioner, replacing the amphitheater with a jogging track, dismantling railings, sanitary dismantling, plumbing dismantling, air conditioning dismantling, removing demolition debris, glass window frames, reinstalling aluminum door and window frames, wall handrails, doors. iron, disposing of excavated gravel, and planting shrubs. RAB analysis revealed changes in cost proportions for various works, such as increases in demolition and architecture and decreases in structures. In October and November, there was a delay in implementing the work due to a contract addendum, which was only approved in mid-October. However, the implementing contractor did not experience financial problems, and even experienced an increase in profit of 0.79%. In conclusion, Variation Orders can affect project time and costs, but flexible contractors can manage them well, and even optimize profits. Effective management is needed to cope with change and ensure the smooth implementation of construction projects.
