ULMA solution

ULMA is providing formwork, shoring, and climbing solutions. The floor layout is currently being done with our CC-4 Aluminium Modular Formwork, light and safe slab formwork with an excellent concrete finish. Some floors required special attention, i.e., the sixth floor, which has a big terrace plus a pool that was part of the shoring details. For these special requirements, ULMA offered MEGAFRAME as the shoring solution because of its high shoring heights.

The distinctive curvature of the building requires a unique solution. From the cellar to the sixth floor, the slab is curved with a big diameter. For this purpose, ULMA's Timber Beam Slab Formwork ENKOFLEX was chosen to go along with the curved diameter. ENKOFLEX great advantage is its incredible versatility and adjustability to irregular geometries, perfect for this project.

ALUPROP is currently used with ENKOFLEX and CC-4 slab formwork systems with bracing frames to erect shoring towers. ALUPROP allows an easy and quick length adjustment. It's lightweight for easy maneuvering and has a high load-bearing capacity. 

The Rail Climbing Formwork RKS system is part of the structure's climbing solutions. The RKS will be used for the elevator core of the building. It is planned to begin on the sixth floor, and all the way up to the last floor.
