Project: 40-level hotel tower in Macau, China
Architects: Zaha Hadid Architects, London
Contractor: Dragages Macau Limited
Formwork Engineering: MEVA Formwork Systems Haiterbach and MEVA Formwork Systems Singapore
The hotel tower City of Dreams, a breathtaking architectural vision designed by world-renowned architect Zaha Hadid, is climbing fast to achieve its 40 level goal on schedule. Dragages Macau Ltd., a subsidiary of Bouygues Construction, won the tender. MEVA climbing technologies are in action thanks to safety, quality and efficiency factors. The cores of the tower are being climbed with the automatic climbing system MAC, the walls rely on the guided climbing sister MGC. Safety is a major requirement. All climbing units must withstand the force of a typhoon wind reaching 250 km/h (160 mph).
The perimeter walls are being erected in a manner that does not disturb the next door hotel which is running normal business. In order to avoid any noise travelling through contact, the MGC was modified with adaptations that allow the MGC platforms to carry both sides of the formwork for walls 1 m thick and the heavy reinforcement loads. Gallow suspension, formwork connections and climbing on complex geometries were customdesigned.
The hydraulic, fully automatic and completely enclosed MAC system is faster and safer than other systems which was essential for the City of Dreams’ steel structure with fast cycles. In addition, scheduling is considerably easier with the MAC system since it includes all walls of the cores. Project management is thus able to pursue an ambitious schedule for concrete works. A two ton gantry crane is integrated in the MAC unit to lift the steel structure below the core. An external working platform follows for work on the slabs. Mammut 350 wall panels are used as suspended shutters and deliver a first class concrete finish thanks to their allplastic facing alkus.
Finally, the completely enclosed working platforms offer optimum worker safety even at great heights.
An unusual hotel with 780 rooms and suites, designed by a team around star architect Zaha Hadid, is being built in Macau (China) near Hong Kong.
The design combines dramatic public spaces and generous guest rooms with innovative engineering and formal cohesion. The rectangular outline of the site is extruded as a monolithic block with a series of voids which carve through the middle of the tower, merging traditional architectural elements of roof, wall and ceiling to create a sculptural form that defines many of the hotel’s internal public spaces.
One of them is that the hydraulic lift pushes off concrete that has already set a considerable advantage in terms of safety and speed. The MAC’s all- around safety housing and comfortably wide working platforms complete its signature as an advanced safety and climbing system. The lift itself is easy to operate with only a small team.
Mammut 350 wall formwork panels are employed as suspended shutters. The standard all-plastic facing in the panel delivers a superb concrete finish throughout the building process. There is little effort in adjusting the shutters in three directions for top accuracy. No special tools are needed.
Another project in which MEVA formwork engineering helps turn Zaha Hadid’s architectural visions into concrete reality: Vienna’s University of Economics and Business also relied on special designs with bent, shaped and pre-formed all-plastic facing sheets to achieve breathtaking concrete forms and geometries.

MEVA STB 450 bietet flexible Lösung bei schmalem und schrägem Streckenverlauf: Nahe der Gemeinde Gretzenbach teilt sich die ansonsten vierspurige Bahntrasse auf. Die südlichen zwei Gleise senken sich dort langsam ab und führen unter der Kantonsstrasse hindurch in den neuen Eppenbergtunnel.
Komplexe Geometrien und hohe Anforderungen stellen die Abteilung Sonderkonstruktion bei MEVA immer wieder vor spannende Aufgaben – wie bei einer Kirchensanierung im oberbayerischen Dorf Hebertshausen.
