Today, the design process in the construction industry are often ineffective because of the changes and delays that accour in the process. The biggest obstacle for construction designers is that they do not get the right information and material in time. The aim in this thesis is to identify the changes and corrections that arise during the design phase. Due to the fact that the construction process is largely time-based, you can by studying the design phase create an understanding of what kind of errors that occur and when in the process they occur. The study was conducted by comparing and studying 14 projects from WSP to observe and detect errors and changes that often occur and to find improvements. From the design meeting protocols 9 types of problems were identified. Based on the problems identified, examples and suggestions were given on how to avoid them in order to be able to make future projects more efficient. To map these changes and errors that occurred in the various projects a correlation was presented between the number of meetings and when in the design phase they occurred. It was done because the projects studied differed regarding size, length and type of construction of the projects. A case study has been carried out in the thesis to develop and gain a profound understanding of the changes and corrections along the design process. To answer the questions posed in the thesis, a qualitative and quantitative research was made. Many of the delays that occur in the design phase is because you often have to go back in the process and in some cases modify already made decisions. Through better planning and continuous monitoring you can avoid making decisions based on assumed conditions and risk estimations. It is of great importance to plan more accurately with clear milestones to reach a well-structured process. When the plans are detailed and clear you can avoids unwanted surprises. This reduces various forms of waste that may later turn up in the process, which means that you get a more efficient use of your resources.
Waste is a resource consuming task that does not create any value. In the construction industry, there is a desire to reduce waste and thus reduce construction and production costs (Josephson & Saukkoriipi, 2009). Of the 14 projects which were obtained this report is based only on 10 of these. The reason for this is mainly due to the lack of documentation and structure. In total, 239 problems where identified from the 10 studied projects. It requires well-functioning communication structures to minimize errors and changes along the design. If you in the beginning of a project have a functioning information- and meeting structures the resource consumption decrease and therefore you get less waste. During the meetings and in the protocols it should be clear who is responsible for each task and it should also be clear when the task should be completed. It is of great importance to decrease the amount of misunderstandings where the consultants doesn’t know who the responsible person for each task is and that clearly showed from the survey results. The waste in the design phase is mainly avoided by having a good and clear planning, a well structure of communication and well-structured meetings. The documentation should also be done in a way that makes it easy to find the information that one is looking for and that benefits future projects by using the experiences. The study shows that communication and experience feedback is important for future projects and protocols provide structure for clearer responsibilities.
