Planering med BIM

Sammanfattning: New technical solutions is popping up all the time. In the construction industry today there is a development to find methods that can take advantage of these modern technological solutions. BIM is a term that stands for this development of information handling and therefore for the streamline and improvement of the construction process. But many in the industry still do not know what the term stands for and therefore not what it means to work with the tools.   A good planning is an important condition for carry out a successful project. Today various techniques is used to establish plans in the construction industry but it is usually traditional methods where the results are presented in a Gantt chart. But there are also other ways and one of those is Flowline. It´s a technique used when the Empire State Building was built. A program that uses Flowline and even claim to fall under the concept of BIM tools are Vico Office. They claim that by planning in their program with Flowline the project period can be shortened by 10-20 %. As previously mentioned many do not know what it means to use this type of tool nor the method Flowline and therefore Skanska wants to investigate it.   The purpose of the study is to provide the reader with the knowledge of what it means to plan with Vico Office and to investigate the flexibility regarding changes in the 3D-model and changes in the planning. The planning was based on a 3D-model of Skanska Project Länsförsäkringar in Umeå. The flexibility in Vico was tested during the construction of the planning. It was tested by upgrading to new versions of the model and by changing the way the building is divided. All this to result in a description of what it has meant to preform out the work.   The description shows that the construction of a planning with a timetable presentation of the Flowline requires a number of different operations. Some of these are control of the model, the creation of calculus, quantity takeoff, creation of a task list, connecting the various parts to each other, location division of the building and creation of Flowline.   The study shows that there are advantages by using this type of technology solutions when planning a construction project. There are benefits such as a flexible location division and a strong visual presentation using Flowline. There are also a number of aspects that needed to be taken into consideration to ensure the success of the method. In addition to the study Vico Office uses many more functions related to planning that can make the program more preferable to use.   The 3D-model that is used as a foundation for the planning needs to be adapt for the purpose and well developed. To avoid work with adapting the planning which in some cases can be extensive the construction projection and modeling need to be far successes in an early stage. A risk with a plan that is mostly performed by retrieving information from a model is that the commitment of those who will carry out the work decreases. It is dangerous because it is one of the key elements of success in planning. Something not to be overlooked is that the experience and knowledge of the planners are very important aspects for the planning to be successful. Because it does not matter how good a time plan is if it is not followed. Therefore it is important to find good work procedures that creates commitment, utilizing experience and uses new technological tools.
