The work is being carried out with the construction company Arcona.The aims are to evaluate and make recommendations about theirbuilding logistics solution CSL. For now, CSL is only used forprojects in Stockholm. If a need for CSL occurs in Uppsala, it willalso be introduced there.The purpose of the study is to investigate how CSL works inStockholm, what good experiences and challenges identified by theusers in Stockholm. Another purpose is to identify which partfunctions of the logistics solution that are requested by futureusers in Uppsala.To find out how the solution works today on projects in Stockholm,three qualitative interviews have been conducted. To find out aboutthe expectations of subcontractors (UE) on a logistics solution inUppsala, a qualitative interview has been conducted with asubcontractor. All interviews were then encoded to find themes andsubcategories.The conclusion is that both the subcontractor and Arcona see bothpractical and financial gains in introducing CSL in Uppsala. The mainadvantage of CSL is that it is scalable and you can choose to insertonly the sub-functions that are needed on the current project. Aservice that both sees benefits and which can be recommended is alogistics coordinator who reviews the entire logistics at theworkplace and thereby more easily identifies and solves problems.
