Abstract

Construction activities are very dynamic activities, large resources and many parties involved. In construction activities are also faced with many problems, one of which is the existence of contract changes or Contract Change Order (CCO) that have an impact on the timing of construction project implementation. This study aims to determine the causal factors and the impact of changes caused by CCO on time, cost and quality at the time of implementation of construction projects on the Lembar - Sekotong - Pelangan Road Reconstruction package project (Lembar - Gili Mas Segment) 2 in West Lombok Regency. To find out the causal factors and the impact of the influence of CCO on the implementation time of construction projects, the respondents' data were analyzed by distributing questionnaires to the parties directly involved in the Lembar - Sekotong - Pelangan Road Reconstruction Package (Lembar Gili Mas Segment 2) Project in West Lombok Regency, Indonesia. Analysis of the results of the respondents' questionnaire answers using non-parametric statistical method Relative Importance Index (RII). From the results of the analysis, it is found that the causal factors and the impact of the influence of CCO are respectively from the construction indicators of design changes during the project and acceleration of work, time indicators of planning and design changes during the project and frequent delays in work, cost indicators of cost over runs (cost overruns) and damage to equipment used in the field, and from quality indicators of less than optimal planning results and quality of materials that are not suitable in the field.
