Siemens Campus Zug Office Building Entrance BIM App

Save with BIM and create added value

Siemens Real Estate planned and implemented the new Siemens Smart Infrastructure Headquarters in Zug, Switzerland, with BIM from day one.

Today, the project clearly demonstrates that BIM helps to plan, build and operate buildings, save costs and sustainably increase their value.


The term Building Information Modeling - BIM for short - has now established itself worldwide for the integrated planning, execution and management of buildings. The digital twins of the building created for this purpose use their data to provide information on outlines, levels and walls with cabling and supply lines (Digital Product Twin), as well as on the installed heating, ventilation and air-conditioning systems (Construction Twin). Together, with current data from the operation, the information from these two twins flows into the digital Performance Twin. As the brain of the building, it constantly learns new things and is used throughout the life of the building to optimize efficiency, for predictive maintenance and for simulations.

BIM from day one

Siemens Real Estate set up a so-called "Big Room" for the Smart Infrastructure Headquarters in Zug in the early planning phase. In front of wall-high touchscreens, specialists from all departments were able to work closely together and plan together - long before the foundation stone was laid. Changes were immediately incorporated into the digital model, which was thus constantly enriched with additional data and grew into the digital overall planning; interdisciplinary coordination between all the specialist planners involved took place right from the start.


The advantages were evident during the actual construction. It was coordinated, without costly planning errors, on schedule and within budget. Around 6,000 possible collisions were discovered and solved during the planning phase alone.


Even in the shell construction phase, the future users were able to "beam" themselves into their future working environment using VR glasses. In a realistic, three-dimensional digital world, they were able to test different color concepts and surface materials, discuss and decide planning and room division topics "virtually".

BIM in operation

In the meantime, the building has been transferred to Smart Infrastructure. Today, data from around 10,000 data sources is fed into the digital twin in Zug. The innovative building technology and sensors from Smart Infrastructure provide the basis for this. Linked and analyzed with MindSphere, the cloud-based, open IoT operating system from Siemens, this data has incredible potential.


According to previous estimates, the costs for energy consumption and maintenance alone are expected to be up to 20% lower, and the total costs for operation, repairs and maintenance (HVAC) even more than 30% - compared to a conventional building of the same size.


And finally, this also benefits local employees. Using the Comfy app, for example, they can book meeting rooms quickly and easily based on current occupancy data. Lighting and temperature are controlled according to occupancy so that an optimal feel-good atmosphere is created. And employee satisfaction increases.
