Building maintenance cost planning and estimating: A literature review

There always exists budget constraint and competing priorities in maintenance needs for existing buildings. The purpose of this article is to conduct a critical literature review on: various maintenance types; and existing maintenance cost estimating models to develop a framework for maintenance budget allocation. A comparative study of current categories in maintenance works and maintenance cost models identified crucial factors that are considered in the decision-making of maintenance cost. Preventive and corrective are main strategies for building maintenance. Performance of these strategies suffers from the allocation of the maintenance budget. Cost estimation models for the different types of maintenance have not been developed yet since lack of a reliable data system. The findings highlight the importance of information system to support inspection building condition, monitor maintenance works and recorded data of building maintenance.
