Abstract The demand for temporary buildings has increased during the last few years. The main reason for this increase is the need for temporary housing.  This thesis contains the development of a construction solution that locks, joins and seals sandwich panels together in temporary buildings. This solution also explains how to mount, de-mount and re-mount the buildings and was developed in cooperation with the commissioning company Swetech Design AB.   The project has been limited to just the horizontal joints of Swetech Design AB´s sandwich panels. The panels which the construction solution is going to be applied on have the dimensions of 2703 mm in height, 2297 mm in width and a thickness of 206 mm. The core consists of cellular plastic that is laminated with a material that consists of fiberglass and polyester.   The pre-study consisted of literature studies of various types of joints, the important properties needed in order to make an airproof construction and the various building requirements for temporary residents. The pre-study also consisted of a visit to the module building company Mobile Composite Solutions (MCS) which helped in acquiring knowledge of mounting big units and the manufacturing technique RTM. Even inventories in different branches were made, to get knowledge around the different possibilities and variations of locking, sealing and joining parts.   After the completion of the pre-study a requirements specification and two function analysis where made that put demands and requirements on the concept solution and expressed the concept in terms of functions instead of solutions. The requirements specification and the function analysis became the base of the idea generating phase. This phase resulted in partial solutions and complete solutions which were then combined together to establish different concepts. Through elimination methods, screening tools and discussions together with the commissioning company a final concept was chosen. The concept is built on a tension joint in combination with a sealing profile and a locking device made of an angle steel, bolt and nut which can join and seal the sandwich panels.   The concept has been visualized in the form of sketches, CAD-model, a physical model on a cut-out between two sandwich panels in scale 1:1, basic drawings and a component list. A proposal for continued work has also been presented in order to assure that the construction meets all the requirements listed in the requirements specification and to make it possible for the commissioning company to implement the concept.

The project explores the possibilities for more sustainable urban development by studying the impact of construction sites on the living environment and public space. The project is focused on the area of Flemingsberg, which in the coming years will be in an extensive development period with a lot of planned new construction and infrastructure. The transformation is planned to last until at least 2050, and for residents and visitors to the area, this means a major intervention in the living environment. Where cranes, fences and excavated materials define the cityscape. To create a bridge through time, the project proposes built interventions for meeting places and focus on the existing needs in the area.The project thus surveys Flemingsberg in depth while trying to create architectural solutions that can be applied in similar situations where large building areas affect the living environment for a long time. All as part of a more socially sustainable urban development.

Mobila verksamhetslokaler erbjuder flexibel lokalförsörjning som alternativ till permanent utbyggnad, eller under tiden som befintliga lokaler renoveras eller byggs om. Denna flexibla möjlighet används dock i en ganska liten omfattning på marknaden. För att öka lokalernas användning finns det därför ett behov av en marknadsundersökning som identifierar de faktorer som kunden värderar. Utredningen syftar till att få fram vad kunden värderar då han eller hon hyr och/eller använder en temporär lokal, och möjligen identifiera nya element som inte finns i marknadens utbud. För att få fram värderingsfaktorer har en litteraturundersökning implementerats och samtidigt har 13 personliga intervjuer genomförts. Intervjuer skedde med personer som använder dessa lokaler och parallellt de som tecknat kontrakt för att hyra dessa lokaler. Studieobjekt är kontor, skola och förskola. / Mobile buildings offer a flexible supply of buildings as an alternative to permanent expansion or while the existing facilities being renovated or rebuilt. This flexible option is used, however in a rather small scale in the market. Thus, to increase consumption of mobile buildings, there is a need for market research that will contribute to find the factors that customer value. The purpose of research is to investigate customer values when it leases and/or uses temporary buildings, and possibly encourage new elements that do not exist in the market range yet. To obtain the valuation factors have been implemented a literature survey and 13 personal interviews were conducted. Interviews took place with people who use these buildings and those who entered a contract to rent these buildings. The study objects are offices, schools and kindergartens.
