The first eight silo cells as well as the headhouse were concreted up to a height of 9.5 meters within four days using a sliding formwork. The constructors worked in shifts round the clock. The fifteen remaining silo cells were also concreted at the same height in a second construction phase with a rebuilt and adjusted sliding formwork. After the insertion of the steel funnels at the same level, the 23 silo cells will be completed in two further construction phases. The construction works for these stages will be performed in 24-hour shift operation in 17 and 15 days respectively. The complete silo block will reach an overall height of 70 meters after its finalization. The shell construction will be completed in mid-July.
