Abstract [en]

The sector for industrialized construction has expanded since the 18

thcentury. Prefabrication of construction elements has become an efficient way to build with respect to reduce costs and save time in construction projects. Today, players in the construction-sector are aware of the grand potentials to build a lot more cost-efficiently with prefabrication as an alternative to the more traditional way of building on site. This report is a study of the construction process for three different methods of prefabrication.

The purpose with this report is to compare different types of prefabricated building-elements with a prefabricated house module that are non-existing in the Swedish market. The study is done with respect to manufacture, transport and mounting of construction elements where pros and cons are weighed in each prefab method.

The one method that are not in the Swedish market yet, are utilized in the USA by the construction company "Blu homes". The concept of "Blu Homes" is prefabricated constructions of complete foldable villas. The folded villas are transported to the building site where they are turned up on the pre-cast foundation before they are folded up into fully finished houses. Their concept has been an inspiration-source to the module that, in this report, is named "Hybrid element". The other two methods that are used in Sweden, is prefabricated flat elements respectively prefabricated "boxes" or volume-elements.

The study shows that the prefabrication of flat elements is more suitable with an eye to transport, because a larger floor area can be transported simultaneously. The volume element method is, however, more advantageous given that a larger proportion of the work can be done in the factory so that the construction requires less work to be done in the building site.

What makes the Hybrid elements to an attractive alternative is that this module consists of both a fixed volume element, and a part that is folded. This combines the both mentioned pros i.e. that it is possible to transport the double floor area with the same number of transport as for a volume element. These two advantages combined makes these elements to a hybrid that can be applied both to the mark for flat elements and also for volume elements.
