UTREDNING AV UPPHANDLINGSDOKUMENT VID OFFENTLIG UPPHANDLING MED FOKUS PÅ ÄTA-ARBETEN

Sammanfattning: Purpose: Today two of the biggest problems within the construction industry in Sweden is the exceeding of budgets and that the projects do not finish in time. One of the reasons is the use of alterations, supplementary- and withdrawn work that occurs during the project. The purpose is therefore to study the variations that can be related to the documents that are used during public procurement as well as provide some suggestions on how the procurement documents can be improved for future projects. Hence trying to decrease the use of variations in projects. Method: The study consists of a multiple case study with three similar projects. The methods that are used are a literature study that provides the base of the intended study. A study of documents is also a crucial element to be able to draw the connections between the procurement documents and the alterations, supplementary- and withdrawn work. There will also be semi structured interviews that will strengthen the case study and increase the knowledge within the area. Findings: the study shows that 60 percent of the alterations, supplementary- and withdrawn work can be connected to the procurement documents. There are a few causes that leads to the use of alterations, supplementary- and withdrawn work in a project for example coordination between the different technical areas within the projects that can lead to contradictions in the documents. Too much material in the procurement documents can leads to conflicting information which leads to the use of alterations, supplementary- and withdrawn work. With greater accuracy and greater coordination between the different technical areas, drawings, and other documents. Coordination between the areas would also improve if it is implemented in the early stages of design. It is important to be clear in the technical description which work is expected from the project which would lead to fewer the alterations, supplementaryand withdrawn work. Implications: the overall problem is in this study is how you can reduce the use off alterations, supplementary- and withdrawn work connected to the procurement documents. Most of the alterations, supplementary- and withdrawn work in a project can be connected to these documents. To be able to reduce the cost there should be a system implemented regarding the review and coordination of the procurement documents. Limitations: This study is limited to three different projects from different municipalities, to secure a more certain result there should be more equivalent projects included in the study. The interviews are limited to the project managers that where responsible for the specific projects in this study.
