18th March - WEBINAR - BIM in Tunnelling - INVITATION


Compared to other branches of industry, digitalisation arrived in construction industry and particularly in infrastructure rather late. To a significant extent, this is due to the very high complexity in the value added chain in construction. Now however, the gap to the other industry branches is to be closed. Many first isolated solutions have been developed in the course of pilot projects, but the required degree of standardisation has been lacking for quite some time.

Therefore, DAUB, the German Tunnelling Committee took the initiative and prepared a recommendation on digital design, building and operation of underground structures, called “BIM in Tunnelling”. This document has been published in 2019 and has been amended by additional “Model Requirements” published in 2020. The work was supported by the Austrian and Swiss partner associations.

The planned webinar gives a comprehensive overview of the basics of BIM in underground construction in general, and the contents of the developed recommendation in particular. It will start from the current situation and will show the application of BIM in tunnelling, as well as provide assistance for efficient practical use.


13:00 Welcome and Introduction

Dipl. Bau-Ing. FH/SIA Stefan Maurhofer, Chair EUTF

13:15 Fundamentals, Planning and Design

Chair: Dipl.-Ing. Lars Babendererde, BabEng GmbH (D)

Digital Design, Building and Operation of Underground Structures – General Constraints Starting point and objectives, life cycle of underground structures, special features of underground construction, project development and realisation based on collaborative contract models, benefits for operation and maintenance

Dipl.-Ing. ETH Heinz Ehrbar, Heinz Ehrbar Partners GmbH (CH)

Basics of Building Information Modelling Multi-dimensional design (from 2D to xD), models, model granularity (LoX), data management and interfaces, limits to the informative value of digital models, roles and responsibilities, modelling rules, use cases for underground construction

Dipl.-Ing. Stephan Frodl, Ed. Züblin AG (D)

Designing the "I" in BIM Increasing importance of semantics and ontologies for knowledge-based decision making with 3D models, standards and procedure for interconnected (BIM) dictionaries, application of (BIM) dictionaries in tunneling domain, concept of rule-based validation of semantics (and ontologies)

Dr.-Ing. Tobias Rahm, DEGES Deutsche Einheit Fernstraßenplanungs- und -bau GmbH (D)

15:30 Implementation and Realisation

Chair: Dr.-Ing. Peter-Michael Mayer, Ed. Züblin AG

BIM-based Design and Tendering Model-based design, coordination, quantity take-off, cost estimation and extraction of drawings, model-based tendering, bill of quantities, tender award, construction preparation and model handover to contractor.

ETH Bau-Ing. Eric Carrera, M. Sc., Lombardi Engineering Ltd. (CH)

Multidimensional Data Integration for BIM Consideration of multiple standards and data models as well as diverging granularity and specificity in data, common architecture considering domains and sub-domains, different levels of abstraction, flexibility of data modelling and data transformation based on pre-defined workflows

Prof. Dipl.-Ing. Mag. rer. soc. oec. Dr. techn. Alexandra Mazak-Huemer, Lehrstuhl für Subsurface Engineering, Montanuniversität Leoben (A)

Example for Application of BIM in a Specific Project Practical hints from an application in a specific tunnelling project, transforming planning into reality, challenges and implementation, added value of using digital tools in the construction phase

Dipl.-Ing. Wolfgang Fentzloff, Implenia Construction GmbH (D)

Questions and Answers During and after the presentations considerable time will be dedicated to questions and answers as well as for discussion of special problems.

Closing Remarks and Outlook

Dipl. Bau-Ing. FH/SIA Stefan Maurhofer, Chair EUTF
