1 INTRODUCTION 1.1 Overview The Building Information Modeling method is wide- ly known and adopted in the building industry. It is the bases to ensure a continuous and consistent planning, construction and maintaining process dur- ing the whole building lifecycle. Using the BIM me- thodology enables architects, engineers, constructors (AEC), operator and owner to create, deliver, and adjust all required semantical and geometrical build- ing data. But the success of the Building Information Modeling approach depends on different core com- ponents (see section 1.4). The building industry itself is divided into two main sections – the structural engineering (SE) and the civil engineering (CE) domain. Unfortunately, almost all BIM research as well as developed BIM approaches are only realized for the SE field. This might be due to the fact that the geometrical objects are simpler in their structure, the reuse of equal ob- jects like doors, windows, columns or entire floors occurs frequently or the implementation of new 3D modeling methods was easier to realize as in the civ- il engineering industry. Further, a lot of BIM specif- ic SE standards were developed, maintained and supported by researchers, industry experts and the buildingSMART organization (BISM 2012). But are there standards available for the civil en- gineering sector? Which existing structural engi- neering BIM concepts could be adopted to the infra- structure process? And which traditional civil engi- neering designing processes have to be changed? Different research organizations like the NIST, GeorgiaTech, VTT, University Osaka or the TUM deal with these questions. The German research project “ForBAU” (ForBAU 2008), for example, developed different concepts creating 3D parametric road and bridge models. Researchers from Japan proposed a new concept defining a product model for shield tunnel projects (Yabuki 2008) and in fur- ther countries like Korea (Shim 2012), Finland (Hyvärinen et al. 2010), Franc (Lebéque et al. 2005) or the USA (IFC-Infra 2011) similar projects have been launched. The aim of all these infrastructural projects is to identify different solutions realizing a standardized infrastructural Building Information Model. In 2011 the buildingSMART organization established the openINFRA initiative (Newsletter 2011) in order to push forward the global implemen- tation of the infrastructural BIM approach.

For this reason the paper proposes a way to improve collaboration between the geomechanical infrastructural design and analysis process, by introducing an infrastructural Information Delivery Manual (IDM). To realize IDM, the traditional geomechanical infrastructural use case was defined and the process specific workflow (activities & data exchange) was determined by developing an infrastructural process map. In order to ensure correct data exchange between the involved processes various Exchange Requirements (ER) were specified. But to the effect an infrastructural product model like IFC is still not available, the data exchange as well as the ER specification was made by different formats. At the end of this research activity the Model View Defi- nition (MVD) was discussed.
