Construction Economy In order for construction projects to be carried out economically and ecologically, this specialist field deals with building management issues that should concentrate in particular on the optimization of building processes. On the one hand, the complexity of the tasks in construction work is increasing due to the increase in technical developments, and on the other hand, major projects are increasing. Moreover other construction contract models are being applied, from the standard price contract to the flat rate contract, all the way to functional tenders. The operator models for large-scale projects by public construction companies are further models that are taken over by the public sector after the usually defined operating phase. Furthermore, based on future developments such as BIM, an increased knowledge of data structures as well as data reconciliation processes in the course of project implementation, the interface problem and the construction progress recording are required. The Competence Center is working on a research project with BIM and, in cooperation with other stakeholders, is working on the basics of IFC structures in the infrastructure sector.
