BIM4ROAD

The German Federal Highway Research Institute initiated the research project "Building Information Modeling (BIM) in road construction with a focus on road maintenance management". Our consortium of 4 university chairs was chosen to realize concepts for a BIM-based data model for the road maintenance management.

The research project consist of the following seven work packages:

WP 1 – International status quo of BIM in road construction

• Analysis of the international trend of the usage of BIM in road construction and related disciplines like rail, bridge and tunnel construction
• Consideration and analysis of the OKSTRA standard, regarding its usage in context to BIM

WP 2 – International standardization

• Strategy of BIM standardization with respect to data exchange, requirements, formats, data management and facility management
• Analysis of the international activity, considering BIM data exchange formats for the road and infrastructure construction

WP 3 – Requirements for a BIM-based road maintenance management

• Analysis and documentation of current processes of the road maintenance management
• Analysis of the current available data and systems of the road maintendance management
• Opportunities and chances to improve the road maintendance management using BIM
• Formal specification of BIM use-cases of the road maintenance management
• Definition of Level of Information for the before mentioned use-cases

WP 4 – BIM data model for the maintenance management

• Specification of relvant OKSTRA object classes
• Specifcation of relevant property-sets for the object classes considering BIM use-cases
• Implementation of a Model View Definition for the BIM use-cases
• Prototypical implementation of the new data model
• Validation of the data model with simple test cases

WP 5 – Evaluation by means of two exemplary projects

• Definition and aquisition of data of two exemplary projects
• Realization of the BIM use-cases for the maintenance management for the test projects using the new data model

WP 6 – Formulation proposals for standardization

• Preparation of formulation proposal for international standardization
• Compilation of test data for international standardization

WP 7 – Project documentation and results
