“Viertel Zwei – Rondo” Residential Complex

Situated next to the famous Vienna Prater amusement park, seven distinctive and up to 33 m high residential towers are currently being realized.
The walls are formed in advance using TRIO 330 which is climbed with the help of FB 180 Folding Platforms; wall and slab formwork operations as well as the complex construction of the circumferential cantilevered balconies are carried out separately.
The TRIO Wall Formwork and SKYDECK Slab Formwork have ensured fast working operations in order to be able to maintain the extremely short construction schedule of only 10 months.
The SKYDECK Panel Slab Formwork ensures similar fast shuttering times for constructing the floor slabs as for the slab of the underground garage at the start of construction work.
The circumerential, organically-shaped balconies ive the residential park an extravagent look and offers extraordinary living comfort.
