In other applications in the world, we often see that disposable formworks are used with fixed heights to make the price advantageous at fill heights below 70 cm. Yes, if there is no installation passage, maybe this application can be done, but if there is the passage of MEP installations, this application can turn into a nightmare.
Likewise, we never witnessed even once that the pipes got between the fixed legs as drawn on paper even if the job site was perfectly constructed to the exact millimetre. On the contrary, the site always called us and asked what to do because the previously laid pipe was in the way of the disposable formwork system's feet.
Of course, there is something to do, but this is a really labour-intensive renovation; the continuous formwork system has to be cut and a gallery for that pipe has to be constructed. Only then the system can continue again. But, what if there are too many pipes? Or, what if the pipes need to cross diagonally? A total nightmare!
