ÄTA ARBETEN FÖR PROJEKT INOM VÄGARBETE : Fallstudie av cirkulationsplats Hammarbykorset, Eskilstuna

Sammanfattning: ABSTRACT Purpose: The purpose of this study is to analyze the different contract changes that potentially could be added to projects made on the road. For this study specifically, a project where a traffic circle is produced, is used as a reference. This is then further investigated by how these contract changes occurred and what type of temporal, economical and technical influence each and every contract change has on the project. By knowing why and how these contract changes occur, there is an evaluation made to list the different factors that entail the contract changes and different methods to prevent these factors which results in less appearing contract changes. Methods: The methods used in this study contains literature studies and case studies as well as analyzing documents regarding the project, calculations made and measurement values and lastly interviews with the different members that are involved in this project. Results: The results gave a perspective of what types of contract changes the project had and how each one affected the project temporally, economically and technically. The results also included answers from the entrepreneur, the client and the consultant for the interviews. It gave a perspective of their view on the project and their thoughts on the contract changes. By compiling their opinions and views one could detect the similarities and the differences. Further after gathering all of the previous results and comparing them, one could identify a common denominator where there clearly is a mismanagement and find ways to fix and evade the problems which results in less contract changes arising. Conclusion: All of the contract changes has been summurized and conlcuded in a UR-sheet. The following conclusions could be drawn from the framing of questions and results: there were a total of 18 different contract changes where as two of these were regulated from outsider factors. The rest were regulated through factors within the project itself, meaning they could have been either prevented or some what predicted and could have had a less of a effect on the project. All of the contract changes had some type of technical effect on the project however not all of them had an effect temporally or economically. The one that had most effect was UR_ÄTA_006 where this was regulated because of a previous project that wasn’t completed in time and stood as a hindrance for the roundabout. This contributed in extra charges, more time spent of certain moments and changes in the timetable. Based on the answers from the interviews, one could conclude that all of the people who are involved in the project think that there are some deficient working power in the project planning. As a solution to the issue, they sugested that one of the people from the entreprenuer side and the client should be some what involved in the early stages and work as a helping hand for the project planning side of the project since they have more experience in how the actual production of a project is done, thus resulting in less contract changes.  Keywords: Contract changes, roundabout, entreprenouer, client, consultant, temporal, economical, technical,, documents
