The integration of media pipes in concrete columns is a practical and, in principle, a very simple solution - if you use the right column formwork for the construction.
Best suited is a circular column former, which can be wrapped around the empty conduits and the reinforcement. This allows the pipes to be positioned simply and optimally instead of threading them "blind" into closed column formers.
The use of climbing formwork is particularly practical, since it is advantageous in handling and provides for optimum compaction of the concrete.
