BIM optimises building planning - first digitally, then in real life
BIM stands for Building Information Modelling, and is the modern digital working method for the integrated planning, optimisation, creation and management of buildings. BIM models consist of BIM objects, the digital equivalent of real construction products. GEZE makes adjustable BIM door objects available for free, to provide greater planning security which requires less effort.

Do you have cost explosions and deadline problems? Seemingly unavoidable with large construction projects such as the new Berlin Airport or the Hamburg Elbphilharmonie concert hall, this seems to be impossible to avoid. And even smaller buildings cannot escape this issue. But public sector clients in particular have high hopes for better things in future by opting for new planning processes and tools: the Building Information Modelling (BIM) planning method is designed to improve the planning and control of construction projects.
In classic construction planning, plans are drawn up in several stages, sent to the authorities, and then revised once more. Creating cost calculations and coordinating individual trade processes on the construction site are also key tasks. But with building projects becoming increasingly complex, these processes often don’t run smoothly., because There are numerous interdependent links and changing relations which need to be continuously taken into account.
Integrated planning with BIM
BIM, or building data modelling, connects everyone involved on one platform and reduces the number of coordination steps. BIM represents a new integrated and digital building planning system which can be seen as a gigantic database. As part of this, all of the objects which are specific to the building (for example masonry, doors, windows, etc. as well as building technology) are digitally recorded, combined and networked in a unique 3D model on which all participants work.
The database also contains all relevant information about the materials and their life span, sound permeability fire protection and, most importantly, costs.
Buildings can thus be designed, modelled, optimised and simulated with the help of BIM. The aim is to implement construction projects more cheaply and simply, and with fewer delays. Additionally, models are not only used for construction: they also make subsequent operation safer, more comfortable and more efficient.
High planning quality
The key advantage of BIM is that all participants - architects and planners, general contractors and builders/operators - can virtually inspect the construction project as a model in the planning phase. Errors and inconsistencies can be identified and quickly be amended at the model stage, which means that the quality, and more importantly the safety, of the planning are greatly improved. Additionally, construction companies can select materials and contractors at an early stage based on the information and proposals stored in BIM.
Use of BIM is gaining ground for public sector construction projects in Europe
The UK, the Netherlands, Denmark, Finland and Norway also prescribe the use of BIM for publicly funded construction projects. In Germany, the Ministry for Transport and Digital Infrastructure (BMVI) wants to use BIM for all new planning projects from 2020.
Advantages of virtual construction with BIM
BIM objects increase planning security and reduce error rates
Digital building models are the core element of the BIM method. These consist of individual BIM objects, i.e. the digital equivalent of real construction products. They are based on structured data which enable product comparisons, for example dimensions, weights, technical product information and manufacturer data such as available variants, order dates, prices, delivery times, installation or maintenance information, etc.
If BIM objects are built into BIM building models, this simplifies the invitation for tenders, cost estimation, calculation and simulation in the planning phase. In the execution phase, this supports ordering, delivery, execution itself and assembly. What's more, it simplifies building management in the operation phase.
BIM objects can rationalise work processes, minimise sources of error and ensure increasing digitalisation in construction.Günther Weizenhöfer, Architect and Team Leader of Planning Seminars at GEZE
Design and deliver construction projects quickly and securely using BIM door objects
All the doors in a building can be planned extremely easily using GEZE BIM objects. In contrast to many other providers, GEZE always offers a whole door as a BIM object, so that the door can be considered with all its components. These multifunctional doors can be used to depict all swing doors, sliding doors and revolving doors. The GEZE BIM objects are free of charge for Autodesk Revit, Graphisoft Archicad and Nemetschek Allplan.
Using GEZE BIM objects
You can download GEZE BIM objects free of charge, and adapt them to the respective CAD program. The BIM objects are available in German, English and Spanish for the following programs:
- Graphisoft Archicad (version 17 or above)
- Autodesk Revit (version 2015 or above)
- Nemetschek Allplan (version 2016 or above)
You can use a web-based component management system to configure doors and projects and then upload these in the CAD software later on. Free plug-ins for the CAD programs Graphisoft ArchiCAD, Nemetschek Allplan and Autodesk Revit allow the use of component management systems, directly from the CAD application
- Generate all door solutions with just a few door types
- Simple and easy to use
- Can be used at every stage of the project
- Complete depiction possible in 3D
- Complete element lists can be generated from the BIM object
- Can also be used offline
Multifunctional door models
You can select the following for these five doors:
Single-leaf swing door
With the parameters behind, you can easily create single-leaf hinged doors with the following components: door closers, automatic swing door drives, hold-open systems, free swing door closers, RWA fresh air door, access control or escape route protection. © GEZE GmbH
Double-leaf swing door
The special features of the asymmetrical double-leaf revolving door can be found on the left in the BIM model: In addition to the basic parameters, there are other options such as closing sequence control, carry bar, configuration of the passive leaf and much more. © GEZE GmbH
Manual sliding door
Manual sliding doors are a practical, space-saving and design-oriented solution. To make your job easier, the most used wall mounting has been specially set here. You can start planning directly! © GEZE GmbH
Automatic sliding door
With the automatic sliding door, you can configure a personalized BIM door object with a wide variety of drive and door leaf types. All options are considered: full glass door, burglary protection, door for narrow profiles, break-out function, accessibility, escape route and much more. © GEZE GmbH
At the touch of a button you can choose between 3 or 4-leaf revolving doors, including between underfloor drive or ceiling drive. For special requirements such as a high number of people or large passages, the many additional options will optimally support your planning. © GEZE GmbH
