Noise is today defined as an unwanted sound that invades the lives of many people in their homes and at work. During a construction phase a large amount of noise is generated that often leads to community complaints. The construction business has to face this issue today when larger infrastructure projects are performed in highly dense areas. Therefore the aim of this Master’s Thesis is to investigate the effect construction noise has on humans and the perceived annoyance in the concerned studied areas, which Bilfinger Berger is contractor for. The impact was studied on both the third party around a construction site on Södermalm, Stockholm and on Bilfinger Berger’s employees on the site. The work concerns three areas, which are situated in the inner city of Stockholm and represent contracts of the infrastructure pro-jects Citybanan and Norra länken. The extensive noise emission during an infrastructure project is affecting the surrounding environment both due to the high noise level that is generated from a number of machines and work activities. Also due to the extensive time frame a project of this kind has. Therefore it is a complex problem to handle and essential for both contractor and client to handle properly. By using appropriate mitigation measures through both the planning stage, the construction phase and clear information towards all parties the impact can be reduced. Through a literature study among the existing science and observations of which mitigation measures are used today to reduce the noise level on sites, a base of theoretical knowledge could be built up for this study. The real noise impact among the affected parties was performed through a survey, which gave results that could be evaluated and discussed. The results from the surveys show that the third party around the workplace is definitely affected by the noise generated from the production. It is also possible to assume that the most affected are persons, which spend a lot of the daytime at home, and therefore feels the noise very disturbing and has to adapt their life after the project’s progress. Through the survey among the employees at Bilfinger Berger a certain acceptance exist towards the noise even if they feel disturbed by the noise. The conclusion drawn from this is that the human attitude to noise impact becomes more positive if they have the knowledge about why and how it arises even if the noise has the same impact on everyone. Therefore the noise issue has to be raised in future projects, even during the tender phase when noise is always easier to control in an earlier stage.
