Analysis of Factors Causing Contract Change Orders (CCO) in the Construction Project of the City Furniture Center Building in Surakarta

Contract Change Order (CCO) is an activity to change the work contract of a project. CCO has become a unique part of a project because the CCO that occurs will be different for each project. The emergence of CCO in the implementation of construction projects will have an impact on project owners and contractors who carry out construction. Therefore, this paper is made with the aim of analyzing the risk factors that cause CCO in construction projects, especially in the Surakarta City Furniture Center Building construction project, which during its implementation found obstacles that forced CCO on the project. This paper was conducted using the Likert scale method approach; Relative Importance Index (RII), and severity index (SI) in order to find the main risk factors for CCO in the project, for data collection in this research was carried out by distributing questionnaires. At the end of the analysis, 3 main factors causing CCO were found, which included differences in the size of work items and building structures required in the field with the plan drawings, the existence of several construction operations that could not be carried out, and from the project owner's request to change the building design. After the discovery of these three main factors, it is hoped that the next development project will be able to avoid the existing risk factors and later be able to improve the quality of work and the final results of existing work.
