Construction projects are faced with numerous challenges
Unbudgeted costs
Unreliable schedule
Insufficient quality
Environmental impact during construction
Accidents on construction sites
Planning errors
Inaccurate, incomplete plans
Lack of cooperation
Difficulty of interdisciplinary realization

Today, the planning process is done sequentially and independently by the
different trades and overlaps with the construction phase

But the future of the construction industry is digital – and built upon a holistic
approach, that connects all parties involved
• holistic process optimization
Process
• reduction of interfaces
• eliminate double work
• consistent data
Data
• enriched data (new dimensions)
• accessible data
Tools
• testing and model checking
(e.g. clash detection)
• simulation and analytics
(big data approach)

BIM is the synonym for digitalization in the construction industry
– a digitally supported process that is built upon four principles
Build
twice
Plan and
build together
Create data
only once
BIM
For the entire life-cycle

What is Siemens doing to promote the use of BIM in the construction industry
1. BIM is the process to
digitalize building
construction
2. BIM process fosters
parallel planning across
disciplines
3. BIM utilizes software
tools to improve
efficiency and
collaboration
BT provides BIM
compliant digital data on
its building technology
products
BT offers cross-discipline
integrated solutions (TBS,
Desigo CC, Room
Automation)
BT develops additional
BIM related services and
tools for end-customers,
architects and
consultants

The Siemens BIM data object libraries: Easy access and always up to date
BIM data from Siemens
is updated and
expanded
continuously. It always
reflects the most upto-date information
Auto updates to the
plug-in automatically
add new products.
Load the software only
once and always have
access to all relevant
and current data from
a single plug-in
Siemens offers
planners holistic and
multi-discipline
solutions – from
building comfort to fire
safety and security
