Using Orthophotography Based on BuildingsLife Software to Inspect Building Facades

Abstract

The financial resources available for infrastructure maintenance and rehabilitation are always limited, creating a need for efficient resources management and for the ability to predict maintenance actions throughout the infrastructure service period. In the context of bridges, management systems have been developed and are already implemented around the world. A much larger variety of maintenance problems and a small number of buildings per owner mean that building management systems are still quite rare. Efficient approaches to the management of building maintenance still need to be developed. The first step in a building management system (BdMS) is the collection of data through inspection procedures to detect and measure the defects, and to characterize the building, which is always a time-consuming task. Software solutions were specially developed within a recently developed BdMS to perform accurate and quick inspections of defects on building façades, using essentially the information obtained in a visual and photographic inspection. This paper describes additional software tools, showing how they help building inspection in terms of characterizing and quantifying several anomalies in façades.
