Logistiska lösningar för en lönsam byggprocess

Sammanfattning: This is a study, the purpose of which is to investigate how the construction company Sefab Bygg AB is able to increase its profitability and render a more efficient production process through logistic solutions. The study is made during one of Sefab´s present projects. The project includes sanitary renovation of 650 apartments in the co-operative Opalen in Norrköping. To find out whether changes of logistic routines are profitable or not, it’s necessary to evaluate the total cost of the changes. A total cost analysis is a mapping of all the costs for a particular material, on one hand for the present situation and on the other after the change. This report includes a description of the present situation. It also includes case studies, to map the flow of material at Sefab today. Suggestions of interesting alternative solutions, has then been developed. With the help of studies and contacts with suppliers an estimate of costs for the suggested changes can be made. Suggestions of changes for Sefab´s logistic routines are "just in time" deliveries and the use of a third parts logistic company even called TPL-company. The TPL-company can offer services such as transports, warehouse and different jobs at the construction site. The result in this study tells us that "just in time" deliveries, is not a profitable solution for Sefab. It would result in a higher total cost and will only make the production slightly more efficient. The services from a TPL-company would on the other hand increase Sefabs profitability and result in a more efficient production process.
