The cost of transportation has strongly increased in the recent years, transportations which are a major part for the construction companies. Skanska Asphalt which is a part of Skanska Sverige AB has noticed that there are significant cost savings to be made with the purchasing of transports. The transports in this case is about asphalt, where the costs are about 10% of the outsourcing business turnover. The purpose of this thesis is to study the working practice that Skanska Asphalt are using today in controlling and time-writing, for the asphalt transportations. Resulting in recommendations on how to improve the working practice at Skanska Asphalt.
This study was conducted with the help of a number of interviews with Skanska’s employees and with suppliers of transportation to describe the practices which are being used in during the asphalt transportation. In the construction industry, every project is different and varies. For every project there is a production manager in charge from and scheduling to the ordering of transportations. For ordering asphalt transportations it’s common today for the production manager to make calls directly to individual drivers or to the management for the contracted transportation suppliers.
It’s mostly common in time-writing to use hand-written notes, but there are also times when the drivers are using PDA for which the transportation management endorses the correctness of drivers information. The major problem is that the charged time for transportation is too high compared to the actual time, because drivers tend to round up the time-writing to the full or half an hour.
Efficiency enhancement within Skanska is important and a proposal for improving working practice that can lead to cost savings is to introduce a different type of tariff. This requires closer cooperation and higher demands on the suppliers of transportation. For this system to work, it’s important to get system support from the suppliers.
With improved internal communication between production managers it’ll result in further efficiency enhancements being found and Skanska will be able to increase the utilization of the asphalt transportation. The planning of the asphalt transportations could improve even further if it had existed any kind of calculation template. If Skanska informs the transportation suppliers in the early stage before the project kicks off with some form of planning calendar with the correct number of vehicles, will make it easier for transportation providers to meet Skanska's transportation needs.
