Abstract
This paper has two main objectives: On the one hand, we want to introduce survival analysis
techniques for use in building maintenance and, on the other hand, to apply this methodology
to analyzing a large building stock in order to obtain information for maintenance strategies
and/or prevention policies.
Similar to technical systems, buildings and their elements are also subject to aging. They age
even faster when they are exposed to external (sometimes extreme) weather conditions. In
this paper we are particularly interested in describing the time to the event when the event of
interest is some damage (or level of degradation) on the building façade which can represent
some risk for people (inside or outside the building). For the time being, building follow-up is
based on inspections. Data coming from building inspections is always inaccurate, but
censored, due to the fact that, at each inspection time, the event of interest has already
happened, or not yet happened. We have adapted the existing methodology for fields like
medicine, biology, industrial engineering or event history analysis, and we have implemented
in S-PLUS®, by Insightful®, the routines for a numerical and graphical systematic analysis.
The potential of this proposal is illustrated with its application to a real dataset. We have
been collecting data for years from all the buildings façades in Hospitalet de Llobregat, the
second most populous city in Catalonia (Spain). More than 10,000 buildings have been
inspected and an exhaustive checklist has been completed for each one. The analysis of the
results allows technicians to detect different zones and levels of intervention to be applied in
the city
