Introduction
#CreatingPerfectPlaces
Buildings talk. Because digitalization gives them a voice.
June 2017 Page 3 Building Technologies
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?

The success of the manufacturing industry is built on the digitalization process – supported by Siemens
June 2017 Page 6 Building Technologies
These are the levers to success in our experience
• Consistent data • Enriched data (new dimensions) • Accessible data
• Holistic process optimization • Reduction of interfaces • Eliminate double work
• Testing and model checking (e.g. clash detection)
• Simulation and analytics (big data approach)

Our BIM experience We use BIM for our own construction projects
New headquarters of Building Technologies Division in Zug, Switzerland • New methods solution frontrunner
New Siemens Campus Erlangen, Germany • Modular approach based on BIM
• Long-term project
• Large-scale project with high repetition factor of similar buildings and components

BIM is all about data: We offer the necessary object libraries
BIM-compliant data according to: VDI 3805/ISO 16757
Guidelines/standard for product data exchange in building services system models
IFC/ISO 16739 Industry Foundation Classes (IFC) – open construction industry standard for the digital description of building models
COBie standard Construction Operations Building Information Exchange
We already have 1,800 products available – and more to come
