We have a new claim: BIM up your elevator!
Over the last few years, we have been working intensively on the BIM topic in the elevator industry. These experiences in combination with our detailed knowledge of the elevator industry, we would now like to communicate to the outside world. Just in time for Interlift 2015 in Augsburg!
What is BIM?
“Building Information Modeling (BIM)“ is a method to optimize the planning, implementation and management of a building using a digital 3D BIM model. The BIM model integrates all the information from the geometrical structure of the objects and properties via a standardized interface into a database. As a result, BIM optimizes the collaboration between architects, builders and elevator companies in the different phases of the life cycle of a building. With BIM, any department may add, remove or update information.
What does BIM mean to elevator companies?
Elevator manufacturers require components (e.g. doors, drives) in a 3D BIM format in order to create a complete digital 3D model of the elevator. The architect integrates this into a 3D model of the building. The advantage of the BIM process is to check the interfaces between the building and the elevator. This avoids typical errors such as wrong floor distances or shaft dimensions.
Once a building is built, facility managers can retrieve information about the building‘s elevators in their digital BIM building. According to the European directive 2014/24/EU, all public buildings should be planned using BIM methods. In some countries like the Netherlands or the United Kingdom, this is already mandatory.
Requirements increase for elevator design software through BIM
With all these changes, the requirements for elevator planning software will increase, as well as users. Up until now, you could copy a similar 2D drawing and adjust it for a new project. This will soon no longer be sufficient as a complete 3D model is expected with all the details.
More than just 3D geometry
In addition to pure 3D geometry, BIM models also have their own intelligence and provide additional information, such as manufacturer, size and type code. BIM software supports planners of all contract work parties with coordination and early error detection. For example, after changing the floor distances in a planned building, the intelligent BIM software automatically updates the rail bracket distances.
BIM in the elevator industry
We are noticing at our customers OTIS, Schindler, ThyssenKrupp and KONE, that 3D BIM elevator models are increasingly required by architects especially for high-rise buildings and large-scale projects. With their ERP systems (e.g. SAP) in 2014, there were worldwide almost 1,000,000 drawings and 3D BIM models automatically created with the help of our integrated BIM software.
Especially now for high-rise buildings is the use of BIM software a strong upward trend. There is a high usage of BIM software being used by vertical transportation consultants. In medium-sized businesses and for smaller projects and buildings, the BIM method has rarely been implemented.
BIM in the components industry
Downloadable 3D models and configuration tools are standard today. Finally, facility managers want to get accurate information, e.g. maintenance cycles or part numbers, about the used components from the building’s BIM model.
The next generation BIM tools for elevator manufacturers will include well-structured elevator components that can be selected and calculated directly in the software.
Today’s BIM processes are becoming more standardized. In the future, digital buildings will be reviewed and modified online by all involved parties (architects, engineers, building owners, notified bodies, etc.). It is conceivable that elevator companies will included an optimized elevator solution into the architectural project and supervise it during all of the planning phases.
This BIM process will finally find its way in the planning of private homes and will attain the small and medium size elevator industry much more evident than it has today.
