A customer came to us with a request to develop a concept, make constructive calculations and calculations of the labor costs of manufacturing modular houses. Modular houses can be manufactured in the factory and brought to the construction site. Modular houses are being built very quickly, which leads to very large savings in the construction of a residential building. The 3d model shows one residential module of a multi-storey building. Unfortunately, modular construction is a very interesting idea, but it is limited in application. You can build only studio apartments and studio apartments. There are no large spaces, there are a lot of problems with fire regulations, but in the end we developed a concept and built several modular houses. Then the customer switched to using concrete modules, which turned out to be even cheaper. But you need to understand that the cost of crane equipment will also grow. A very interesting project in our piggy bank.
