This thesis treats Building Information Modeling, BIM, in the production stage. Brieflydescribed BIM is virtual model of a building object where all information about theobject is gathered. All the involved operators in the construction project have access tothe model and can gather or share information about the project. There are several waysto apply BIM in the production stage. This thesis primarily deals with visualization of theobject, preparation and planning, the ability to take amounts from the model andcoordination and clash control.The basic issue was highlighted by Byggdialog AB. The company has a vision about howthey want to use BIM in all the different stages in a building project. Byggdialog wanttheir partnering entrepreneurs to develop their BIM usage in the production stage inorder to fulfill this vision. Goodtech is one of Byggdialogs partnering entrepreneurs andis the company that has been studied during this thesis.The goal with this thesis was to develop proposals as to how the BIM usage in theproduction stage can improve. The purpose was to make the partnering entrepreneursunderstand why it is important and helpful to use BIM. The intention was also that otherpartnering entrepreneurs should be able to use this thesis while working with BIM inthe production stage.The methods to collect information have been visits to construction sites, literaturesearch, and interviews. The interviewees represented different operators that can affectthe usage of BIM in the production stage.This thesis resulted in concrete proposals as to how the partnering entrepreneur canimprove their BIM usage. Proposals as to how Byggdialog can ensure that theirentrepreneurs are using BIM correct have also been developed. Today the partneringentrepreneur uses BIM tovisualize the building object. As a suggestion the entrepreneurshould also use the BIM model whilepreparing and planning their work and in order tocalculate material amounts.It?s important that the entrepreneur understand how the model can be used and whatkind of information it contains in order to enable these applications. It?s also importantthat the design phase is carefully executed. Proposals as to how this can be achieved is toeducate the staff in BIM and how it should be used, that the partnering entrepreneurparticipates in the coordination meetings and that the partnering entrepreneur placegreater demands on their electrical consultant.In order for Byggdialog to ensure that their partnering entrepreneurs are using BIMcorrect they should offer them education about BIM and how it works, make the BIMmodelmore user-friendly and place demands on how they want BIM to be used in theproject specifications.
