Does prefabrication have a chance? In principle, the answer to this question is a very simple YES, as prefabrication is already an essential part of planning and construction today. In the construction industry, it ranges from smaller elements such as prefabricated shaft elements for building services to prefabricated staircases, lift shafts, suspended elements such as balconies and larger modules, especially in timber construction or industrial construction, to complete systems and the boom in single-family house construction. Prefabrication enables automated and weather-independent production and leads to the highest quality standards. The higher the degree of prefabrication, the shorter the construction time, the lower the risk of accidents on the construction site and the lower the level of dust and noise emissions for neighbours. All these advantages lead to the most important factor of prefabrication - cost reduction, which is more important than ever due to the current unstoppable rise in construction prices, the scarcity of building land and the exploding land prices. If you look around on many construction sites, you will see that, apart from the already established cavity wall systems in reinforced concrete construction, relatively few prefabricated elements are being moved (with the exception of timber constructions). This is because a high degree of prefabrication in the execution phase has its origins in the design. At this stage, the architect and builder must already have made all the necessary decisions (building material, fittings, external appearance), as late decisions or rescheduling lead to cost-intensive and time-consuming changes and even delays, and many builders want to remain as flexible as possible in terms of execution in order to be able to approve one or two special requests during the construction period. This advantage for the buyer also offers the possibility of customising the individual residential units as opposed to the possible monotony. Conclusion: The higher the degree of prefabrication, the more economical larger projects in particular are. This requires early decisions and a certain planning lead time in order to have the finalised implementation planning available before the start of construction.
