Development of a Digital Restoration Process Covering the Entire Value Chain for Heritage Conservation in BIM

In the research project DenkmalBIM, the IIB, in collaboration with various practice partners, is developing a restoration process for heritage conservation. The goal is to develop a new BIM platform to cover the entire value chain of the restoration of existing buildings.

In Germany, Building Information Modelling (BIM) is gaining increasing importance. This approach allows all relevant building data to be digitally modeled, captured, and combined in virtual 3D models, making the entire planning phase faster and more flexible. However, BIM has been scarcely used in the field of renovation and restoration of (heritage-protected) existing buildings, primarily due to the lack of interfaces between the trades involved.

Therefore, the project's goal is to develop an innovative BIM platform that covers the entire value chain in the restoration of existing buildings, with a special focus on heritage conservation. This platform is not intended to be an archive but will be a dynamic database including an interactive design tool for the first time. The idea is to develop automated interfaces between the new BIM platform and the software tools used by those involved in the value chain, facilitating data exchange through the platform. Additionally, the capture of buildings as well as the reconstruction and modernization measures and manufacturing planning will be 100% digitized and represented on the platform. To this end, new capture strategies will be developed for various applications, defining both the methods of measurement (e.g., combining different sensors) and the information to be documented (such as color, materiality, etc.) and levels of detail. This aims to enable largely automated restoration and manufacturing planning. With specially developed tools, the restoration of existing buildings and the (additive) manufacturing of replacement parts will be significantly more automated.

Institute of Numerical Methods and Informatics in Civil Engineering

The Institute of Numerical Methods and Informatics in Civil Engineering focuses on BIM in both research and teaching. In teaching, the topic is primarily covered in relation to the classical planning of new construction projects and the associated collaborative work in a shared Common Data Environment. BIM also plays a significant role in research.

The experiences gathered in other projects of the institute serve as the foundation for developing the DenkmalBIM platform, which will enrich the value chain for heritage conservation projects.

Institute of Structural Mechanics and Design

The Institute of Structural Mechanics and Design has been intensively exploring the application of additive manufacturing in construction for several years. Several research projects have focused on additive manufacturing processes in metal printing and ceramic printing. The ISM+D places a strong emphasis on the structural and building physics properties of the printed components, in addition to the manufacturing techniques. This experience will make a significant contribution to the development of the project.

3D Welt Vermessung GmbH

3D Welt is an expert in surveying historical buildings. Until now, the focus has been on generating data for documentation purposes, mainly capturing the general structure of entire buildings. 3D Welt already uses a variety of sensors for surveying, bringing extensive experience in this area. In some cases, high-resolution measurements are already being taken.

Priedemann Fassadenberatung GmbH

Priedemann Fassadenberatung GmbH is an expert in facade consulting, planning, and construction. Besides their expertise in complex new construction projects, the company has experience in building renovation and recognizes a significant current and future market demand in this area.

In the planned project, they will build on existing preliminary work. By focusing on digital planning methods and processes, the project will distinguish itself from previous efforts and generate new knowledge, particularly in the field of heritage-protected buildings.

Dipl. Ing. Hölscher GmbH

The company Dipl. Ing. Hölscher GmbH has been involved in the digitalization of the construction industry for several years. In addition to planning construction execution and design, the company also processes materials, handling construction execution and assembly. They have also gained initial experience in additive manufacturing.

Given their prior work and the expertise of their employees, Hölscher is well-equipped to carry out the planned tasks in this project.

Hessenpark

The Hessenpark Open-Air Museum has been carefully preserving and reconstructing historical buildings since 1974. Over the last 50 years, more than 120 buildings that could not be preserved in their original locations have been reconstructed according to scientific principles.

With its extensive experience in the preservation of historical monuments, Hessenpark offers ideal conditions for testing new technologies and innovative approaches in a practical environment as part of this project. There is close co-operation with partners in order to effectively implement advances in building restoration.
