Successiv projektering : En kartläggning av informationsflödet
Sammanfattning: A construction project is not the other project alike. Despite this, there are a few subprocesses that a construction project cannot do without. However, the order in which these occur and how far in time these sub-processes extend may differ depending on the project's conditions. What is common is that a construction project is initiated by its project design where project planning documents and later on construction documents are produced before the production begins. But as the construction projects shortens in time, higher demands are placed on streamlining the sub-processes. It has therefore become increasingly common for the project planning to take place gradually along the production. This master thesis is mainly based upon those interviews that were conducted during this study. The interviews were held with different peoples of either contractors or constructors. The main aim with this master thesis were to study the flow of information between those who plans the project and those who executes it, within a project were the project is been planned and designed gradually along the production. In order to form an understanding of how the flow of information work, the tools and methods used to manage information are studied in a project were the project is being planned gradually, seen from both contractors and project designers perspective. It turns out that there are relatively small differences in how the information is handled between a project that is planned gradually versus one that has been planned in advance. The tools used to spread (downstream) and report (upstream) information are the same regardless type of contract. However, what a project that is planned gradually benefits from is the choice of working methods used in the project. These working methods can facilitate the handling of the project information and the information flow created up- and downstream. The conclusions that can be drawn from this thesis are that a project with gradual planning combined with its information flow benefits from a project that is being carried out in cooperation. Which is based on the fact that the communication routes have been clearly identified at an early stage. It will both facilitating and reducing the flow of information compared to if the project would not had been carried out in cooperation. The time gains that are considered to be possible when the project is gradually planned ceases to exist if the project is not carried out in cooperation. In addition, a gain can be seen in being able to streamline the current management of how the information is being both managed and spread from the project planners. Regardless if the project has been planned prior to the production or not. However, given that work tasks such as planning/design and production are particularly close together when planning a project gradually. An efficiency in improving the project planners work while distributing the building document can increase the space for mistakes without impacting on the detailed time schedule.
