Abstract [en]

An organization that wants to reduce their costs in the long term must develop their methods so that the same product can be produced with fewer resources. A more effective flow of logistics contributes to reduced cost and increased profitability for the construction company. With many internal and external actors involved in the supply chain it is not enough that the contractor is individually effective, but he should also be effective together with other actors. Therefore, focus on both the flow of production and material as well as the connecting flow of information, is needed to achieve an effective flow of logistics. Hence, the purpose of the study was to identify and describe problems relating to the flow of production, material and information at a construction site from a management point of view, plus to identify actions in order to streamline these flows.A case study consisting of interviews and observations was conducted at Nåiden Bygg AB:s construction site in Gäddvik, where the flow of production, material and information was studied. The study had an explorative orientation and an abductive approach with existing theory concerning Lean, Agile, the construction process and its flow of logistics, presented in a theoretical frame of reference, as basis. The theoretical frame of reference was then compared with gathered data from the case study, whereby further relevant theory concerning planning and communication was obtained.The result of the case study showed that problems related to the flow of logistics at the construction site existed; material was stored for a long time; material was lost; work was conducted in an ill-considered sequence; lack of clear directives to machine operators; low detail level on the production plan; worker knowledge was not considered when planning; long communication chains; flaws in the communication with subcontractors. Further, two of the problems were considered having large effect on the production, plus pronounced relations to each other as well as to many other problems that the case study had identified. These problems were low detail level of the production plan and flaws in the communication with subcontractors. The study shows that the contractor, in order to solve these problems and to achieve a more effective flow of logistics should: Assure that project participants are informed and reminded of the project goals. Organize an establishment meeting with a clear agenda for all project contractors. Spend enough resources to establish a detailed production plan in the early stages. Discipline the structure at coordination meetings. Produce guidelines for how much time that should be allocated to planning and for the detail level that is demanded of the plans. Look over planning technique and encourage and educate planners to use net planning instead of traditional planning. Produce routines for how subcontractors should be involved in production planning. Study the results from the construction project at hand and use those experiences in future, similar projects.
