The Alon Towers consist of two symmetrically arranged, 164 m high twin towers. They are part of the new, modern "BSR Center TLV" office complex and are redefining the skyline of Tel Aviv. A special architectural feature is the X-shaped façade design which is perceptible from all sides. Both towers taper to the halfway point and then widen again to the top.
For a cost-effective execution solution, PERI's Israeli engineers combined several climbing system variants. The system concept was perfectly matched with the climbing formwork and protection panels as well as exactly meeting construction site requirements.
Tailored implementation concept
PERI Israel has provided an ideally matched implementation concept on the basis of the ACS and RCS Self-Climbing Systems as well as self-climbing CB Platforms. As a result, the construction crews can work very efficiently also at great heights – protected against the wind and concealed from view as well as being crane and weather-independent. The PERI comprehensive package complete with planning services, on-site support and logistics ensures, in particular, compliance with the high quality and safety standards. In addition, the strict construction schedule as well as the limited crane capacity have been taken into account.
Climbing formwork and protection panel
The climbing formwork solution for the building core is a combination of ACS, RCS and CB in connection with VARIO GT 24 Girder Wall Formwork and suspended DOMINO Panel Formwork for the intermediate walls which follow. With the decision to construct the core in twin sequential phases in each case, the cycle sequence has been adapted to match the execution of time-critical reinforcement work.
The circumferential enclosure and anti-fall protection of the top floors of the shell construction in each case is being realized with the RCS Climbing Protection Panel, geometrically adapted to suit the forward and reverse-inclined façade as well as being designed for the required change of inclination at heights of almost 80 m. In the process, the RCS Climbing Protection Panel units climb crane-independently with the help of mobile self-climbing devices to the next floor each time. An important part of the PERI Protection Panel solution features the integrated landing platforms which facilitate temporary material storage and for moving loads with the crane.
