| Abstract | The construction industry is exposed to various risks. Many such risks occur only during the construction phase. Because of exogenous and endogenous factors, failure of equipment is frequently encountered during construction. The objectives of this study are to quantify amount of downtime and corresponding cost impact on road projects in Nepal. Also the major reasons for downtime, which thereby increase cost, are identified. This study was conducted at nine road projects using all types of equipment, which are most commonly used for flexible pavements. The cost impact due to downtime was aggregated by recording cost impact for the broken equipment into five major cost items, namely, repair cost for breakdown, idle cost for operators, labor and supervisors, idle cost for equipment, cost for substitute equipment and other miscellaneous costs. The major causes for downtime were found by use of a questionnaire survey carried out with 16 road contractors and ranked according to the mean value of importance. From the study, it was found that the average total cost impact for road projects is 3.6% of total budgeted cost of work scheduled for corresponding average downtime of 6% of the total working time. The predominant reasons for downtime are lack of genuine spare parts, lack of proper and scheduled maintenance and unskilled mechanics. |
