Module construction of multistory buildings in Norway: A comparative study on limitations, structural performance, cost and serviceability

Abstract

Modular construction focuses on making prefabricated modules and elements with preinstalled services in order to reduce the construction time, whilst also maintaining the structural performance and safety of the building. Though this have not been used much in Norway, it can be observed from other countries that this method has many advantages and disadvantages. To name a few, the construction time is faster, the cost can be reduced, inventory spacing can be managed more easily, labour cost can be reduced, labour safety can be improved, while still satisfying the structural requirements for the job. Furthermore, modular construction may be a more affordable solution to the housing crises in underdeveloped countries and a solution for cheaper student housing. This paper focuses on comparing the structural performance, cost, advantages, disadvantages, limitations and serviceability between traditional cast-in-place concrete elements, precast elements and prefabricate modules.
