“Partner project impact” with a focus on the form of collaboration's impact on subcontractors is the starting point of the work. Partnering is an area of knowledge that is unfortunately still placed in the background. From the labor market to teaching, the ignorance of partnering is noticeable. Whether it depends on the generation working in the industry or the lack of interest, is difficult to answer. This ignorance of the form of cooperation and its significance aroused interest in this report and the hope of creating a greater interest in partnering. With Byggdialog AB as a helping company and their extensive knowledge in the field of partnering, research has been done on how the work environment and finances affect the subcontractors in a partneringproject compared to other projects with, for example, a fixed-price contract.  Partnering is a way of working where you work together from an early stage towards a common goal and with open finances. The contractor must be involved at an early stage together with the customer to arrive at how to create the best product, where they include the subcontractors already in phase 1 to jointly develop the best way of working.  The economic factor of upcoming and ongoing projects is of great importance to companies and their choices for upcoming projects. Relationships and collaborations between all parties in the project, from client to main contractor and subcontractors will be a new factor that has to be considered before the next choice of project.  The purpose of this report is to investigate whether partnering has any impact on a project and the subcontractors in the project. The work compares projects with and without partnering to see if the open economy has any impact and if it affects the work environment and the work on site. The goal is to create an overall picture from client to craftsman and see if the form of cooperation has any significance. The work will be based on these issues.  • How do the subcontractors' craftsmen experience that partnering affects the work on site? o How does job satisfaction differ between projects with and without partnering? o How does the subcontractor experience that workinghours are affected by partnering? • For what financial reasons does a subcontractor take a job on a partnering project?  The method for examining the issues were carried out through interviews and questionnaires to examine the soft parameters that partnering is about, humans, relationships and cooperation. The interviewees will be all parties in the project to get the overall picture. In addition to these interviews, literature studies as scientific reports are used to increase the credibility of the results, but also to create a better whole of the study. The results and conclusions were based on the methods and are reported according to the points below. • Partnering has a positive impact on the workplace. The relationship between all subcontractors is experienced as more open and better when the financial self-interest disappears and the communication between all parties is clearer. • The work environment is perceived to be less stressful and thus increases well-being in the workplace. Through a good work attitude between each other and for the common goal, the risk of extra work on evenings and weekends is minimized. • Partnering creates security in a troubled market where you deal with the problems together and work together for a better project. A market with high competition makes it difficult to consider the options of choice for the next project. But good relations and cooperation are in many cases more profitable for the work environment and the economy, and are factors that affect the next choice of project.
