IDENTIFICATION OF BUILDING- AND USAGE-DEPENDENT PARAMETERS WITH SIGNIFICANT IMPACT ON MAINTENANCE EXPENDITURE VIA LIFECYCLE ANALYSIS

In order to counteract the further increase of maintenance backlogs, building maintenance needs to take center stage in the upcoming years. Especially owners of large property should try to optimize the maintenance of their building portfolio using a minimum of resources. To this end, the correct calculation of the maintenance resources required is vital. Within the context of the research project BEWIS (Optimized upkeep strategies to maintain value of buildings), the department for Facility Management of the University of Karlsruhe (TH) analyzed twenty buildings regarding maintenance or value-increasing measures. The analysis concerns all value-maintaining or -increasing measures realized over the complete lifecycle of a building. The specific objective of the project is the development of a calculation tool for maintenance cost. A number of building- and usage-dependent parameters, like the age of a building, its technical equipment or the buildings geometry, have to be considered. The analysis of real lifecycle data helps to identify parameters that have significant impact on maintenance expenditure.
