Abstract:
This diploma thesis deals with the investigation of different manufacturing options for shell and façade constructions on the basis of a sample project. For the shell construction, the use of in-situ concrete, semi-precast, prefabricated and timber components in the area of walls, columns and ceilings is examined and analysed with regard to economic and scheduling aspects. In the end, the mixed form of the examined variants leads to the best result. According to this, the use of semi-precast elements is particularly useful for structural elements with a high repetition effect and standardised dimensions, while the in-situ concrete construction method can be used well for special geometries. Precast elements have their advantages for complex and dimensionally accurate designs. From an economic point of view, semi-prefabricated parts in solid construction as well as timber construction are best rated. From a scheduling point of view, the use of prefabricated elements ensures a short construction time, but planning lead times must be taken into account for all prefabrications. For the implementation of possible changes of use, a skeleton construction is the best option, as there is a high potential for combining or separating individual rooms. For the façade construction, the execution of a composite thermal insulation system, a timber curtain wall and a prefabricated concrete façade are being investigated. While the ETIC system offers the greatest possible flexibility, the timber curtain wall and also the prefabricated concrete façade have an enormous influence on the shell construction due to the respective weights.
