What advantages does BIM... offer? This time for the TGA planner

Technical building equipment is a significant and integral part of building design, construction and maintenance. As a rule, it includes the design and execution of systems for heating, sanitation, air conditioning, ventilation, electrical engineering and building automation as well as transport technology.

The importance of these functions is obvious, therefore facilitating the work of TGA planners is an essential step in the digitization of the construction industry. BIM makes this easier.

BIM reduces the workload

Until now, a TGA planner had to enter the same master data several times because he had to plan the design of the heating network and the drinking water network separately. The problem: Changes and updates (e.g. to the architectural design) led to high adaptation costs. These adjustments often resulted in errors and collisions that only became apparent during construction or commissioning.

Thanks to BIM, data can be exchanged with other participants in the project. This reduces the effort required for multiple master data entries and makes it easier to update calculation models when changes are made to the overall model.

A plus: Parameters determined in the calculation model can be transferred directly into the model and information aspects can be visualized. For example, unfavourable flow paths become apparent earlier.

Continuous exchange

The transfer of calculation-relevant data is of decisive importance. TGA planners need exact values of surfaces, cubators, wall structures, facades and all physical properties. Only a few years ago, this information was exchanged between different sources, resulting in unclear assignments and different work statuses. The result: reworking, postponement of deadlines, loss of quality.

Thanks to BIM, TGA planners and architects are in constant exchange. This is particularly important for new buildings. Both have access to the building model and can therefore plan and update the technical equipment. Collisions are detected during the planning phase and can be remedied.


A further point in the TGA planning of a building is the maintenance. The complexity of maintenance depends on the size and use of the building. Highly engineered buildings need modern methods to maintain it. BIM provides the appropriate data and facts to make this possible.


In the end, BIM also achieves the already known goals in TGA planning: You save cash and rare time. In addition, planning is simplified and the error rate is reduced through more precise planning. Quality and longevity are essential factors in the construction industry.
