Unlike the manufacturing industry, the construction industry is always in motion. Each new construction project brings new opportunities, and it requires a new plan, new organisation, and new suppliers. All construction projects are very different from each other and in terms of a logistical perspective, this is very weak as it makes it difficult to get a flow in the production and to make flawless routines. The way the external and internal logistics are managed, can effect the final product in the time taken to produce it, the quality of the product and the profit made from it. When internal logistics are handled poorly, it could result in materials not being at the right place at the right time, or information not going through to the right person. Small details such as these, can make the production time increase continuously with the price. Logistics is all about efficiency; to make things quickly and in a well organised manner. Although making things right is vastly important, it is also important to make things correctly as doing things quickly and efficiently becomes meaningless if there are activities that are unnecessary. The purpose of this report is to identify factors that are central to an efficient logistic on the construction site and which factors can be influenced by the construction site. However, the study does not include any concrete suggestions for improvement, but there will be some discussion around it.
There are already some concepts and tools that can improve the logistics, for example, the use of Lean Construction and BIM. Logistics work should be included in all stages of the construction process: design, planning, production and managing of the actual building. This report mainly relates to the design- and production phase.
There are different approaches and objectives when planning projects. A primary objective is to reduce costs. The main goal in logistics planning is to achieve short lead times, short set-up times, short transport distances, and eliminate waste.
The result of the report is based on literature studies, observations, but mostly interviews. Three interviews were held with the management, i.e. the supervisors and site managers. The implementation has compiled information from interviews, observations and literature studies. It was discovered that there were many similarities, but also differences that separated the various projects. For example, it was found that a crane is an important asset for a smooth operation as it moves material around the site, but there is a lot of time wasting when unloading, partly due to the lack of communication. It also revealed that it is hard to know what operations to begin with at the construction of the framework.
Conclusions drawn after work designing is planning and communication are two of the most important building blocks to get a smooth production both for functioning internal and external logistics. What has also emerged is the importance of accessibility and that doing the right things should come easy. An external factor that effect logistics a lot on the construction site is the demand, for example, of materials from their suppliers. The final conclusion raised is ultimately an improvement suggestion: apply a logistics manager to all types of construction projects, from the beginning and throughout the project.
