Our challengesSpecial features of underground construction
The ground is our main construction material
Generally high geometrical complexity with all its uncertainties

Our strategyOur strategy: Implementation three major steps
2025
2020
2015
Development phases 1 Convergence 2 Digital Competence 3 Digital Transformation
project-related model-based collaboration network - related integration of projects data-based holistic solution
- Developing of processes and first - Integration of the entire supply chain - Assets are planned, designed,
guidelines for BIM (Planning, design and construction are constructed and operated
fully integrated in BIM) continuously with BIM – fully digital
- Piloting BIM for design;
- Major use cases for operations & and collaborative
piloting of planning and construction for
major use cases maintenance are developed, piloted - Digital Twin is embedded in a digital
and implemented ecosystem, which enables exchanges
with third parties
(e.g. governmental authorities)
digitization
transformation
March 18, 2021 EUTF-Webinar 17Fields of action in our Strategy
§ clear definition of the ideal typical final state
1 Strategy
§ measurable milestones
§ team based collaboration – no silos anymore
2 People
§ Involve the team / reduce fear / training and education
§ Data architecture based on supplier independent interfaces
3
Information/Data § Standardized object and element libraries
§ define customized / new processes - get easier
4 Processes
§ clearly define new roles and responsibilities
§ Software/services follow the increasing requirements
5 Infrastructure IT
§ Common Data Environment on a safe cloud environment
§ Application in projects and in test use cases - do it!
6 Application
§ Integrate end-user requirements

The DAUB recommendation
(May 2019)DAUB recommendation on “BIM in Tunnelling“ (May 2019)
Preamble The following fields of action should be given priority for a
beneficial application of BIM in underground construction
1 General constraints
§ Standardisation of ground modelling
2 BIM basics
§ Standard catalogue of components for underground
3 Design preparation construction
4 Design § Soft- and hardware
(modelling, project management (CDE)
5 Construction preparation
§ Conditions of contract (collaborative partnership)
Digital Design, Building and Operation of
6 Construction
Underground Structures
§ Contract award practice
BIM in Tunnelling
7 Operation § Training for young professionals and users
