Due to the continious platforms, the external formwork for the steel composite columns extended around all four sides of the structure and could either be raised all together, or on one side of the structure at a time, on the Doka Automatic Climbers, in exactly one hour. This resulted in a weekly cycle for the core and the floors with formwork being lifted on Monday, and reinforcement and formwork on Tuseday and Wednesday. On Thursday, pouring (with high-strength concrete) was carried out with formwork being struck on Friday. From the bottom to the top

From its first ‘climb’ from the concrete base-slab, the Doka Platform SCP was already in its assembled state, and continued to the 43rd floor without needing any further modifications( except that an additional outside scaffold was suspended on two of the sides from the 30th storey upward). Thereafter, the platform was easy to dismantle, even at a height of 148 m above the ground.
This enabled work to proceed exactly on schedule, leading to successful completion of the carcass in August 2000. Hochtief is currently continuing with the interior finishing work, seeing the structure through to completion on a ‘turnkey’ basis.
