BIM-supported work planning in SMEs

Methodology of work planning in small and medium-sized enterprises in the construction industry using process-relevant project data of a digital building data model.

Funders: Bundesinstitut für Bau-, Stadt- und Raumforschung (BBSR) im Rahmen der Forschungsinitiative Zukunft Bau

Project term: 10/2016 bis 05/2018

The research project "BIM-gestützte Arbeitsplanung in KMU" is considered part of a large-scale project on the use of the BIM method over the life cycle of buildings. The aim of this is to advance the standardisation efforts of building data models in terms of processes and the associated information flow between the project participants in all life cycle phases. This will help to create transparency with regard to the BIM method for those involved in the construction process, while at the same time conforming to the law and standards.

As part of the project "BIM-gestützte Arbeitsplanung in KMU", the focus will be on the processes of work planning in small and medium-sized enterprises in the phase of realising construction works.

The execution of construction projects requires an intensive exchange of information between planners and construction companies. This task can be effectively supported by the BIM method. However, BIM software has so far been used predominantly as a planning tool for building design. The benefit for the construction organisation (here especially the work scheduling) has so far been almost unused and not or only marginally investigated in the scientific basics. Within the framework of the research project, a procedure is to be developed that will also enable small- and medium-sized (SME) enterprises to work with the BIM method and to use the data provided by other construction participants for the processes of work scheduling. Currently, there is a lack of information on the work planning methods used in practice by SMEs, the tools used for this, the type of data and their update intervals. This is where the research project comes in. Based on expert interviews, literature research and an extensive survey, the work planning processes and the data needed for optimisation are to be analysed and integrated into the large-scale project. Compared to the BIM Institute's other research projects "BIM-basiertes Bauen im Prozess" and "Digital Bauen mit BIM in Deutschland: Fokus Bauausführung", both funded by the BBSR as part of the Zukunft Bau research initiative, an even more detailed breakdown of the processes from work planning in the realisation phase is being carried out. In the processing of all research projects, attention is paid to a networked and coordinated processing, especially with regard to the process data structure. The aim is to demonstrate how the construction companies carry out their work planning, which data they process and in which format this data must be available for the software available in the companies.

In addition, software tools for reading data from digital building models will be analysed and specifications for programming a data interface will be drawn up. On this basis, a software interface ("data viewer") will be developed with which SMEs and craft enterprises can connect to the data of a BIM system without having to use a modelling tool (e.g. Autodesk Revit) themselves.

The results of the research project will provide scientifically sound findings on the quality of work planning of the largest group of construction service providers. The development of the software interface should enable SMEs to use BIM planning data for their processes. This tool can not only increase the productivity of the companies, but also improve the quality of the projects from the perspective of the client.
