A persistent problem in the construction industry is its low margins of profit. It is often difficult to earn money due to low efficiency and high costs. Logistics on the construction site answers for a large amount of these costs and it is therefore of interest to find new, more efficient logistic solutions. The purpose of this thesis is to compare two different logistic systems and further to evaluate which one that is the most efficient and profitable. A comparison is made between the traditional logistic systems used for years and a new logistic system developed by an industry association called BEAst. The survey was conducted in cooperation with Peab Sweden AB on two of their construction sites in Västerås, Sweden. Findings show that the modern logistics system is more effective than the traditional, but that the traditional currently is more profitable. A more comprehensive establishment of the new system needs to be done in the construction industry in order to reduce the cost of logistics way, and to work out major routine in the workplace in order to minimize errors and create more intelligent solutions.
