Samordnat materialflöde - Fokus vid komplex stadsutveckling (med koppling till H+ i Helsingborg)

This study concerns materials logistics in the construction processes of complex building projects in urban developing areas, where the authors have carried out a case study on the future urban renewal project Oceanpiren, H+. Urban renewable projects can be regarded as a common category in construction, due to increasing urbanization followed by an enhanced demand. This type of project is often represented by intense and hard challenges in managing efficient material logistics. A complex urban renewable project is commonly described by three following traits: involving more than one developer, hard geographical conditions and an intense surrounding urban environment. The limited amount of space that exists on the work sites for unloading, storing and moving materials creates even harder conditions in managing the delivered materials. The intense surrounding urban environments may have an interfering impact on the construction processes and likewise can these projects have similar effects on the surrounding urban areas. The numerous amount of developers may result in an increased intensity in the material logistics on the work sites and accordingly implies a greater difficulty to work efficiently. Moreover, this higher intensity and greater amount of building actors also make it harder for each of the developers or contractor to cope with others’ work activities. In order to manage this complexity the authors investigated how relevant coordinated material logistics between developers would be in and how this would achieve a more efficient building production. In the process of answering this thesis’ research question the authors decided to collect necessary data in two ways: a theory investigation and several interviews. The interviews were held with selected respondents from different category groups from which the authors received different approach angles to the questions asked. Accordingly this provided broader and extended results for further analysis and discussion. From the comparison between coordinated and individual materials logistics the authors gained an understanding of the significance role coordination between developers or entrepreneurs have in complex urban renewable projects to acquire a more efficient building production. In the conclusion of this thesis, the authors outline that due to every projects’ unique character there is a need to identify the right suitable level of coordinated material logistics solution to meet the specific demands in the specific building project. Moreover, there is a high significance in communicating demands for this decided method to every involved actor because it will create equivalent conditions in the construction production. The authors also states two general and fundamental aspects that should be included in the materials logistics solution in this type of project: appoint someone responsible for the material logistics in the project and to establish a coordination system, including time scheduling, that controls the flow of materials in and out from the building site. A specific elementary solution for Oceanpiren, which has been named “Checkpoint” by the authors, includes the two aspects presented above and an additionally station for receiving incoming materials. Therefore, it can be concluded that a right adjusted coordinated material logistics method between developers is a prerequisite that needs to be practiced in these complex urban renewable projects to gain efficiency in the building production
