Executive Biography



Construction projects are faced with numerous challenges

Unreliable schedule

Insufficient quality

Environmental impact during construction

Accidents on construction sites

Planning errors

Inaccurate, incomplete plans

Lack of cooperation

Difficulty of interdisciplinary realization

Unbudgeted costs



The manufacturing industry faced similar challenges –

how did it improve?

Overall



The success of the manufacturing industry is built on

the digitalization process – accompanied by Siemens



These are the levers of success according to our experience

• holistic process optimization

• reduction of interfaces

• eliminate double work

• consistant data

• enriched data (new dimensions)

• accessible data

• testing and model checking

(e.g. clash detection)

• simulation and analytics

(big data approach)

If the construction industry omits typical planning errors,

the productivity will be similar to the one of the manufacturing industry

BIM is all about data:

BIM knows different dimensions that help us to plan and operate buildings

The data model evolves over time…
