Halmstads Energi och miljö (HEM) is making major upgrades in its facility where it will replace its cooling system from current water cooling to air cooling. The new cooling system is desired to be placed on the roof of the facility. However, the existing roof isn't built to carry such a heavy load. This thesis will be coming up with a concept for a load-bearing structure that can be placed on the existing concrete pillars that already exist at the facility today, so it doesn't apply all stress to the roof. The ground for the work is based on discussion with the company and a theoretical study where the desire and requirements for what the construction must withstand have been realized, which the study has since worked to achieve. During the literature study, knowledge was gathered about what the constructions must cope with to meet building regulations and euro standards. After finding out the forces and marginal constructions needed to get through, various concepts were developed. The most suitable concept was then selected by using the pugh matrix. After selecting the concept, the concept was constructed in a CAD program where FEM calculations were used to dimension the concept to ensure that it can withstand the forces it will be exposed to. The results of the study were a structure that can reasonably be placed on the existing concrete pillars where the new cooling system can rest on. The construction at the same time meets the requirements required by the euro standards.
