Civil engineering, which is the central part of infrastructure, is of great economic importance and has considerable resource relevance. In this context, the public sector in particular is significantly involved in all construction life cycle phases.

RekoTi is a systemic approach to increasing resource efficiency by closing mineral material cycles in municipal civil engineering. Here, the efficient use of resources during the entire value-added cycle - from planning, construction and maintenance to dismantling and disposal - is taken into account in conjunction with legal and administrative requirements.

In the inventory, current framework conditions from the areas of technology, administration, economics and law are surveyed. In addition, innovative, resource-specific technologies and processes as well as management concepts are compiled and further developed.

The collected data will be analyzed and evaluated with regard to resource aspects. Deficits and potentials in technology, administration and economy with regard to an increase in resource efficiency in mineral material flows will be identified and derived in a recursive process to optimization approaches.

The method BIM - Building Information Modeling has a central role here, as it is used as a linking instrument by the acting actors from the different areas as a tool to support the decision for an optimal resource strategy.

On the basis of the optimization approaches, a civil engineering resource plan is to be drafted for the city of Münster, which is to ensure the closure of mineral material cycles by means of a suitable management strategy. The transfer to other municipalities also plays a role and is to be simplified by the creation of a guideline. The internal and external coordination ensures the success and visibility of the project. The consortium ensures that other municipalities and companies can also use the corresponding approaches. Due to the high interest of the addressed municipalities and their networks, a rapid dissemination in the area is to be expected.

The transferability to other use cases is given. The scientific exploitation and connectivity can be seen in the instructions for action for closing the loop, the tender guide, the interdisciplinary increase in competence, new methods, instruments, procedures, consulting and F/E-projects for other municipalities, practical transfer through teaching and training.
