Cumulative Consequential Cost Analysis for Construction Machinery Breakdowns - United Arab Emirates Perspective

摘要

Modern maintenance strategies have helped minimize the breakdowns in machinery. However the total elimination of breakdowns in machinery in general and construction machinery in particular is a remote possibility. Breakdowns in construction machinerydespite scheduled preventive maintenance practices are due to; unattended preventive maintenance schedules, extreme climatic conditions, dynamically varying working environment, machine mix of old and new in the same fleet, differences in operator competence levels and over utilization of components and systems. Further, breakdowns results in loss of morale, developmental losses apart from the costs involved. The downtime of each machine poses threat to its own performance and as well affects series offollow on activities which are always parallel and inter dependent in the construction industry. The cost of machinery failures have not been systematically analysed in the region and this case study analysis proposes a cost model to identify the cumulative cost effect of such failures.
