It is a concept that potentially could benefit the construction industry in several different ways. Many believe that BIM will revolutionize the industry in the future. The buildingSMART data dictionary (bsDD) is an international standard developed by the neutral organization buildingSMART. It is a standard that defines the terminology surrounding BIM objects. Much research has been done on the potential benefits of BIM in general. However, no research has been made on the immediate consequences of an implementation of the buildingSMART data dictionary. The purpose of this thesis is to determine how a property development and construction company, that already works with BIM in many of its projects, would be affected by an implementation of the bsDD. The possible consequences of bsDD implementation are mapped out and analyzed through a literature review. In addition to this, a simulation is conducted with the purpose of showing how object libraries can be created on an organizational level. The findings of this thesis show that the consequences of a bsDD implementation can be summarized into three categories; technological, operational, and contractual consequences. The main consequences of the implementation would be that the employees would have to be provided education and continual support, through guidelines and internal BIM standards etc. The consequence with the largest impact, however, would be the task of creating an object library. This task is required since the bsDD does not have any Swedish content yet.
