A new luxury and a standard hotel with 330 and 205 rooms are being built next to the main entrance of Munich’s expo facilities. Both hotels are located in one complex to be opened for business in the autumn of 2013. Scheduling was tight, leaving only 9 months for building works on the 8-storey complex with a layout of 132 x 59 m. This required careful planning with foresight.
Floating ceiling for conference room
The conference room on the ground
floor measures 29.50 x 14.80 m and
has a floating ceiling at 5.70 m height.
MEP shoring towers with single props connected with bracing frames were perfect for the job. MEP 450 and 300 props were connected to square tower units, 110 cm wide. Walls extended through two levels are designed to carry the slab and the MEP shoring tower was employed to take up these loads also. Formwork could be stripped as soon as the slab above the second level reached the 28 day setting time. For static reasons, bracing through to the foundation slab was required.
Different wall heights
The basement floors are 2.80 m and 3.70 m high, the ground floor 5.70 m and the upper levels 2.85 m. Mammut wall formwork with its 97 kN/ m² load capacity was used to pour the walls, allowing rapid pours and saving time in the tight work schedule.
Round walls and columns
The popular circular formwork system Arcus achieved a superior finish on the rounded walls of the parking garage access ramp. Only two sets of the foldable mobile column formwork CaroFalt with basic heights of 360 and 270 cm plus a 120 cm extension were needed to complete all columns at a rate of one per day. The circular columns were formed with the steel column formwork
Circo that provides a continuous
first class concrete finish on columns
with diameters between 30 and 70 cm.
Slabs and beams
Beams measuring up to 2.60 m in width and 1.10 m in thickness were poured before the slabs. This was done with 125 cm Mammut panels set horizontally. In inaccessible areas where all tasks had to be done by hand, the light-weight hand formwork EcoAs took over. Because of the beams, all slabs above the basement and ground floors, 30 to 45 cm thick, were poured using the conventional MevaFlex wooden girder method.
Safety and time-saving solution achieved with special designs
From the first floor upwards, the slabs float on concrete edge beams. A custom-made solution provided the answer: slab edge tables measuring 3.90 x 3.70 m and made of MEP shoring towers. The tables acted as a support grid and were assembled without facing. They were equipped with a working platform on the front and a safety railing that provided optimum worker protection. The tables were lifted as a complete unit using a transport spreader from one level to the
next, saving assembly time. On building
sections with outer walls, the
folded working plattform KAB 190
provided a safe working situation.
Where necessary, the Mammut wall
panels were placed on the 190 cm
wide platform. Cantilevering parts
interrupt the facade on the southern
and northern side. In order to ensure
worker safety, a shoring tower with
prop frames was used.

MEVA fulfils stringent requirements with flexible formwork solutions. The Budapest Zoo & Botanical Garden is one of the Hungary’s most popular cultural attractions.
MEVA STB 450 offers flexible solution for narrow, inclined rail section: Near the municipality of Gretzenbach, the four-track route branches into two separate lines. Here, the two southern tracks gradually descend and pass below the cantonal road before entering the new Eppenberg Tunnel.
