the brackets are lifted by crane to the next concreting
Through the use of a special anchoring system, the
construction team has achieved the required finish here.
All the walls, without special requirements for the visible
surfaces, have been quickly realized with the proven,
large-sized TRIO Panel Formwork.
For the, up to 6 m high, circular columns, the SRS
steel Column Formwork fulfils the requested surface
Under the slabs, which in part are inclined and up to
30 m high, load-bearing scaffolding, Peri UP Modular
Scaffolding and ST 100 Shoring Towers have been used
depending on the loads involved.
Earthquake-proof shoring solution
for a suspended roof
The entire structure of the Greek National Opera is cov-
ered by an additional 10,000 m² large canopy. This is
suspended about 12 m above the actual roof and some
40 m above ground level .
This additional roof is actually the central element
in order to achieve the planned target of emission
The construction consists of a prefabricated ferroce-
ment panel arrangement which is subsequently spliced
together with a mortar fill.
Solar modules supply the "green" energy to cover
part of the electricity requirements of the complex. The
shape of the canopy resembles a convex lens – the
cross-section tapering towards the edges.
Thirty very slender steel columns support the con-
struction and are arranged in a 15 m grid formation on
a steel frame.
Load transfer into the ground takes place via the
building´s supporting columns positioned below. Visually,
the columns seem to merge into the supporting structure
of the Greek National Opera.
A major challenge for this very extraordinary archi-
tecture and the special design of the roof was the erec-
tion of the required shoring solution during construction
In the process, the scaffolding has to assume a variety
of functions. On the one hand, it serves as a support for
the prefabricated ferrocement modules and simultane-
ously allow fine adjustment of these modules in their
On the other, safe working
areas with easy access for the
required assembly work and
concreting operations had to
be created around 2 m under
the roof surface. Last but not
least, the temporary scaffold-
ing construction had to be

using a telescopic crane
as the structure gradually
grew out of the ground.
