The presented 'Documentation and maintenance planning model' (DoMaP) is a proposal for a new approach to acquisition of various types of data from façades of modern generic multi-apartment buildings. The DoMaP model aims at substantial contribution to stringent status assessment of façades, and thus, to enable long-term maintenance planning, providing adequate conditions for integrated sustainable conservation. The DoMaP model is based mainly on optical techniques (i.e. metric as well as non-metric). Techniques for air pollution monitoring, and for material analysis are included in the DoMaP configuration. The benefits of this new comprehensive approach to data-acquisition may be summarised in provisions for increase both of efficiency (i.e. resource utilisation) and effectiveness (i.e. productivity and quality) of façade-maintenance operations, thus also contributing to sustain technical service-life and functions of residential structures.
