Trump World Tower III, New York, USA
Only two days for a complete floor
With its height of 258 m and its luxurious furnishings the Trump World Tower completely re-defines the New York skyline. With restaurants, 24-hour concierge service, reception, security staff, room and delivery service for groceries etc., the highest residential building in the world provides a pretentious atmosphere of the highest level.
Two main load-bearing walls divide the building plan into three sections. On the wall to the South there are three shafts. The façade consists of 27 columns in the lower floors. Their cross-sections, positions and number change on the way up. The normal floor height is 3.25 m, the formwork having been designed for the maximum concrete lift of 3.86 m.
Only 22 of the 27 external columns were formed by PERI because the remaining area served as crane access for lifting the floor slab and wall formwork onto the next floor. The twelve ACS-R units on the façade were raised with five hydraulic power packs. A separate power pack was available for each of the three shafts. ACS-G brackets, on which the VARIO shaft units were mounted were used because of the narrow shaft width of 2.36 m.

The building contractor worked to a scheme that is typical for this part of the world: the façade columns, main load-bearing walls and shafts were formed together with the floor slabs. Columns, walls and shafts are concreted first, and then the floor slab. |

The 187 strong workforce constructed a complete floor in a three-day cycle, and cut this cycle to two days for the normal floors from the 22 nd floor level. |
