The DemoS research project deals with demographic and structural changes in Germany. In addition to profound social changes, it also brings with it structural, spatial and technical challenges. Delays in planning and construction processes are often due to deficits in inventory data collection, processing of existing components and insufficient digitization of existing information. Four of the six areas are for prospective inventory management systems, including an automated building and building climate management and monitoring system, building-level imaging systems, including appropriate communication systems, strategies and information-based tools for land use planning and monitoring of processing. the economic adaptability of the construction and real estate sector. All tools are supposed to be low-threshold tools that allow you to work smarter with existing building resources. The objective is not a complete BIM model, but the practical assistance of various actors – instead of the distance indicator and the inch ruler, VR glasses could be used in the future for larger sizes .
The study "Building in Inventory 4.0 – Empirical Foundations from an Architect's Perspective", described in section 5 "Strategies and Tools for Construction, in the field of digitization, data transfer and from the inventory data collection, showed that the construction sector still has significant deficits and inhibitions the Conversion Planning "of Lena Salm and Sofie Seifert under the direction of Alexander Stahr, Professor of Industrial Design . The architecture and planning offices of all federal states were surveyed about the use of digital tools in their daily planning routine. Only an extremely small proportion of 3.6% of planners, despite the BIM, perceive the status of digitization in the construction sector relative to other sectors of the industry as a trend. At 49.6%, however, almost half of those surveyed believe the sector is lagging far behind. Even though, in conjunction with digital aids – which are generally understood as classic CAD software tools – we are talking about "global thinking, optimizing workflow, a higher level of detail and of better communication, (….) the work is done based on data formats with a relatively low information depth ", is described in the study. Not even 25% of planners are currently working with BIM trading formats. The divergence of the current situation of the planners is illustrated, among others. The fact that more than 77% of respondents consider that BIM planning methods are a trend, but at the same time 90.2% are incredible, takes into account the structural interventions on stocks in a similar way to the rule and the distance indicator. The reason for this was, among other things, that, for example, although a laser scanner provides more accurate data, the large amount of data from scatter plots would generate unnecessarily high costs for the data. evaluation and planning. If we also consider that the (digital) acquisition of data and information in existing buildings is a significant problem and that these services are not sufficiently covered by the HOAI, it is clear how many obstacles, are not only technical, are the digitization of existing buildings. The processes in the build in stock are.
