A pilot project of the German Federal Ministry of Transpor- tation (BMVI) for the integration of BIM 3D construction en- gineering data with existing GIS environmental and plan- ning data for the optimization of infrastructure planning. BAB A99 BIM and GIS Pilot Project • 2D and 3D GIS data preparation and BIM integration • 3D BIM model data preparation and integration • 2D und 3D visualization of results Client Project Execution Project Period Services Project Leader Project Partner SSF Ingenieure AG in cooperation with the Autobahndirektion Südbayern SSF Ingenieure AG PSU│Prof. Schaller UmweltConsult GmbH 2016 SSF Ingenieure AG Esri Deutschland Group GmbH Fig.2: The integrated BIM and GIS GeoDesign Concept Fig.1: Project area and bridge structure The purpose of the project is an eight-lane expansion of the federal motorway A99 between the interchange Munich North and the junction Haar, with a length of 18,6 km (Fig.1). Be- sides renovation of bridges and superstructure, noise abate- ment measures are also planned. The focus of this pilot project are the future requirements for a frictionless information sharing between engineers and en- vironmental planners, to optimize all required environmental concerns from the start of the planning phase, through pro- ject implementation, completion, and to monitoring the envi- ronmental measures. GeoDesign as a concept for the integration of BIM & GIS When geo-information is used in a design process to as- sess possible consequences of environmental changes, we speak of “GeoDesign”. For the implementation of the construction project, BIM and GIS workflows are united in a common workflow in this context. As a result, the BIM/GIS database is available to both engineers and environmental planners through a single interface (Fig.2). BIM (Building Information Modeling) is based on the idea of a continuous use of a digital 3D building or infrastructure model over the entire life cycle of the building, from design through planning and execution, to its operation and decommissio- ning. The BIM concept groups the main stages of modeling into five supergroups (Fig.3). The GIS planning progress is analogous to the BIM process in various steps. In addition to the planning process, a GIS data scheme is built, which can be divided into a 2D and a 3D dimension.
