BAM Division 7.1 – Building materials focuses primarily on research into the mechanical performance and durability of building materials. A part of the multidisciplinary team examines ways of improving material behaviour under varying conditions and a part assesses and analyzes damages and damage mechanisms that lead to degradation of materials under different environmental conditions. Due to its many projects involving cultural heritage objects and monuments, the members of Division 7.1 have sound expertise in the properties and behaviour of various materials used for historical and ancient monuments. They are aware of the requirements of the cultural heritage authorities and trained in communicating with conservators, property owners and decision makers. As part of a large research organisation, Division 7.1 has access to many techniques and instrumentation, of which the most important for the project are in the division’s responsibilities.
In the framework of the national funded StandardLEHM project (2008-2011) with Claytec e.K. as project partner and the Dachverband Lehm e.V. as associate partner, technical guidelines for testing earthen materials were developed. StandardLEHM was funded by the German Federal Ministry of Economics and Technology (BMWi) under their funding instrument MNPQ. Significant results of the project have been adopted in the national standards for earthen materials.
The mechanical behaviour of earthen materials under earthquake actions and strategies for low invasive intervention techniques to strengthen historical earthen structures in seismic areas were investigated and defined in the NIKER project (2010-2012). NIKER (New Integrated Knowledge-based approaches to the protection of cultural heritage from Earthquake-induced Risk) included 18 international project partners and was funded by the EC under the umbrella of the 7th Framework Program.

Students can use the opportunity for internship, thesis or personal research. To Nka, designing is not the whole thing. The design education question is: How do you learn to design what is buildable? It is by designing and building a project! Nka Foundation has come to know that by immersing the young designers in the full circle of designing and building their design, at the completion of the design-build process, the emerging professionals will learn to design what is buildable to make a well-rounded graduate. For the professional, you will find the hands-on construction experience a pause from your office work to rediscover the rudiments of design and nuances that can refresh your practice.
