The second stage is distributing questionnaires to construction companies registered with the Palangka Raya City LPSE for 2020-2023. The third stage is processing the data using the SPSS computer application to test validity and reliability, before analyzing it using Descriptive Analysis to determine the ranking of dominant factors. Then a Difference Test (Mann-Whitney) was carried out to determine the differences in opinion between the contractor respondent group and the supervisory consultant. The research was conducted in August-November 2023. The results of the literature study show twenty factors that cause Contract Change Orders on construction projects in Palangka Raya City.

So H0 can be accepted, namely that there is no significant difference in the factors causing Contract Change Orders (CCO) between contractor experts and supervisory consultants
