Logistics planning for a construction site is usually limited by traffic flow to and from the workplace. The geographical location of the construction site is determined by roads around the workplace and opportunities for well-functioning logistics. Inventory of material is often impossible because of the frequently small workspaces. As a result, a concern relating material handling remains . Even before the establishment of a construction site, it is required in the construction industry to eliminate errors that might arise in the planning stage. The aim of this study was to contribute with better understanding of the relationship between well-planned logistics and reduced costs at the Swedish construction company Peab. To clarify this a survey was submitted at two construction sites and a sample of calculations were performed on reduced / additional costs at examples of "good" and "bad" planning of logistics, to show how to reduce costs.

Higher requirements are placed on construction firms and demand such as shorter project times and lower costs and this is supposed to lead to a high profitability. To increase the profitability it is required that the construction industry is planning the amount of resources, manpower, material and time in the absolutely best way. Logistics is a part of the construction industry which may help reduce costs and provide greater profitability, if it is seen as a saving and not just a cost. There should, in other words, be a greater emphasis on planning of the logistics already at early stages of projects.

There is a great amount of work on purchase of materials in the company Peab in the current situation, but if the company also put equal work on logistics, the planning could be optimized even before the project starts. Through good planning Peab will not only save on cost of purchase, but may also contribute to a better handling of material. Better handling of material also contributes to reduced costs for the project. Material is not only bound capital but can also disappear in waste, thievery or even destroyed. This is also appreciated by both professional workers and employees in the workplace. The opportunities for improvement and efficiency of logistics at Peab are great. By selecting a logistics manager at each construction project and also having a specialist in charge of the region that serves as support for the projects, Peab can save on logistics. The purpose of this report is to look at changing the view of logistics today on construction sites. The result of the calculation examples and survey shows where the largest cost items located in the various projects and how to achieve lower costs through better planning. This in turn helps the company increase profitability in the long term.
