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
