Construction projects affect the community in both positive and negative ways. Positive effects are, for instance, better communications, better housing, and a higher standard of living. However, construction projects inevitably bring with them deterioration and changes on the local plane, at the site of the construction project. Thus, in construction projects, many different and sometimes controversial interests must be considered. Representatives of these interests are referred to as the project stakeholders. The stakeholders in a project can be divided into internal and external stakeholders, the internal stakeholders are those who are members of the project coalition or who provide finance; the external stakeholders are those others affected by the project in a significant way The purpose of this research project is to contribute to, and increase, our knowledge concerning external stakeholder management in the construction process, and to develop methods and tools for the evaluation and management of external stakeholder influence. The contribution of this study to construction project managers is: - An increased knowledge of how an external stakeholder management process presents it self in construction projects. - Suggests different strategies to an external stakeholder management process. - Suggests different tools that can be used for analysing the influence of external stakeholders. The main tool, described in this study, is the stakeholder map and the power interest matrix.
