Abstract:
This diploma thesis evaluates the logistics parameters for a building extension in timber and timber hybrid construction with the aim of providing planning support with regard to the necessary boundary conditions, technologies and cost dependencies. The work deals with the extension of a prefabricated building of the type WBS 70, a common building type in the new federal states. In view of the current housing market and the limited availability of building land in inner-city areas, the retrofitting of additional storeys represents a good alternative for creating additional living space quickly and cost-effectively. Firstly, planning support for retrofitting additional storeys is presented in the form of repair methods. This is followed by a comparison between prefabricated timber elements, consisting of timber panel elements and timber hybrid full assembly ceilings, and the conventional construction method with semi-prefabricated elements. The suitability of new types of prefabricated timber elements using the lean method is discussed and the advantages and necessary boundary conditions compared to conventional construction methods and the accompanying construction planning are shown. This comparison serves as a planning guideline. Furthermore, the economic prerequisites for successful value creation are defined, whereby the prefabricated construction method with prefabricated timber elements appears promising. The importance of reducing the weight of components and sustainability aspects such as the use of CO2-neutral raw materials and sustainable production and logistics are discussed. In addition, further parameters for continuous further development, such as the successful implementation of the lean method, are identified for future research activities. The thesis thus contributes to the expansion of knowledge about building extensions in timber and timber hybrid construction and aims to make the planning processes more efficient and targeted.
