This thesis is ordered by Peab Sweden AB Regional Jönköping and concerns of warranty inspections.

The intention is to work out a basis, which show the most common complaints is the warranty inspections, and make a small analysis on what causes them to be. The report also presents possible solutions to prevent the occurrence of defects. It also covers the issue of how the client looks at Peabs way to overcome the objections of warranty inspections. The report has the following issues:

•What are the most common errors observed during the warranty inspection?

•What are the causes of complaints?

•What can be done to reduce the number of complaints?

•How the customer thinks that the complaints be addressed?

Twenty-five Guarantee survey records from the projects Peab has done in recent years has been the starting point for the investigation. In the protocols, we have categorized the remarks and made a compilation of common remarks. Through interviews with inspectors, buyers, site managers and Peab's inspection team the results have been analyzed and interpreted.

These survey methods have resulted in various proposals for measures that can reduce the remarks. An example may be to inform professional workers in the building about what the most common remarks are and how to guarantee that these can be prevented.

The compilation is categorized according to the most common complaints, construction types, actors and types of buildings.The compilation of inspection protocols showed that the cracks are the most common complaints. The interviews gave confirmation that the survey compilations of protocols were equivalent to reality.

The conclusion is that the most common complaints are mainly cracks in the wall corners, roof angles and doors that need to be adjusted. These remarks are mainly due to the tight construction times, sloppy and wet materials that are installed. But there are also many other factors contributing to many of the common faults of warranty inspection that cannot be defined as a single cause. Interviews with clients revealed that they are satisfied with the way Peab remedy defects observed at guarantees, while the survey does not disturb the residents/production.
