2. What are the future works mentioned in the paper "Building information modeling (bim) for existing buildings – literature review and future needs" ?
Although some sustainability ratings already include some end-of-life considerations [ 247,248 ], BIM might be used to integrate monitored values such as energy consumption, waste water, or maintenance costs into their rating or to extend current assessment criteria with regard to recyclability or other end-of-life considerations on component level.. But future research approaches could also include material- or texture-based recognition [ 151 ] and non-destructive testing methods such as ground penetrating radars, radiography, magnetic particle inspection, sonars or electro-magnetic waves [ 205 ] or tags installed during retrofits to increase information richness in BIM.. And further capacity developments in this area are expected to facilitate BIM implementation e. g. through cloud computing, sensor networks or semantic web approaches [ 150,179 ].. To cope with these issues and to reduce time and cost, the integration of monitoring and capturing methods into BIM seems promising to keep BIM information automatically up-to-date.

3. What are the major challenges in new buildings?
Major challenges in new buildings refer to change from design-bid-build processes to integrated project delivery (IPD) and to the increased time effort and knowledge required for BIM use.

4. What motivates the architecture, engineering, construction, facility management and deconstruction 1 communities to manage?
Resource scarcity, sustainability challenges and stricter decrees for recycling and resource efficiency in buildings [1] motivate the Architecture, Engineering, Construction, Facility Management (FM) and Deconstruction 1 communities to manage resources efficiently [2].
