Abstract

Change Orders often occur in construction project, whether during early, middle, or late stage of  project. The objectives of this research are to find types of work and construction stages where change orders often occur; average percentage of change order costs anda main causes of change order in flexible pavement project in East Kalimantan. Data for the research were obtained by first, distributing questionnares to project and field coordinators, contractors, and consultans working in Samarinda, East Kalimantan. The findings show thar cut and fill works in sub grade often experience change order. The main causes of change order are differences between drawing and site condition, design changes, and landslide. The average change order’s percentage is 28,26%. Meanwhile change order often occurred during the early phase of construction.Keywords : Change Order, Flexible Pavement, East KalimantanPermalink: http://ejournal.undip.ac.id/index.php/mkts/article/view/3664[How to cite: Sulistio, H. dan Waty, M.

Abstract

Early risk identification of the sources and causes of waste material for road construction projects has been carried out, and the research continues to carry out further risk identification which then becomes the final risk identification. Description and validity tests and reliability tests were carried out to obtain further risk identification. Each source variable and indicator of the cause of material waste in each material is differentfrom one another because each has a difference. The results of continued identification resulted in:   1) ready mix concrete has eight variables of waste material sources and 21 indicators of material waste causes, 2) lean concrete has seven variables of waste material sources and 18 indicators of material waste causes, 3) aggregate B has seven variables of waste material sources and 12 indicators of material waste causes,  4) landfill has eight variables of material waste sources and 26 indicators of material waste causes, 5) cement has seven variables of material waste sources and 31 indicators of material waste.
