Recently, research on 5D processes has brought innovation into the construction sector. However, one still feels a lack of clarity in this sector. Although BIM research has been carried out in many countries, very few standard building processes have been clearly identified. The RIBA Plan of Works in the UK, and the HOAI in Germany can be used to support the designer for the description of the services expected from them. Whereas the new RIBA Plan of Works 2013 [15] already includes some support, in case of the HOAI building owners can still hardly find guidance about the contracted design processes and how BIM processes are to be aligned with the overall process structure. Information exchanges are not defined and there is a big uncertainty about how to implement BIM in construction projects. To rectify this, the Reference Building Process Map is proposed including all relevant processes in the design and construction phases for the main stakeholders (owner, architect, technical experts, constructing company, public authority and consultants). In particular, the BIM Manager role is added with its interaction with the other stakeholders. Based on this process map, the steps which are mandatory for the sustainable certification process are also identified. The advantages of using BIM for the certification process are clearly pointed out. In its advanced form, each major process is described by the BIM data requirements to be carried out efficiently. The BIM data requirement management identifies the data needs with regard to the Level of Detail (geometry) and Information (property content). It also addresses the responsible role for delivering and validating BIM data, and enables automatic checking procedures to guarantee the right BIM quality for the BIM processes.
