solution for iconic structure
Not far from the Faliro bay in Athens, the Stavros Niarchos
Foundation Cultural Center (SNFCC) is being built based on a
design by leading architect, Renzo Piano.
Peri is supporting the construction of this extraordinary
project with a comprehensive formwork and scaffolding
solution. This includes continuous on-site supervision
along with a matching logistics concept for managing
the vast amount of materials. The Peri solution, devel-
oped in close cooperation of engineers from Greece and
Germany. This has made an important contribution in
ensuring that the very strict construction schedule has
been maintained, and the high architectural concrete
requirements could be fulfilled.
The architectural design followed the highest envi-
ronmental standards – among other things, through
emission-neutrality and the appropriate choice of
The highest possible architectural concrete quality,
as well as the temporary support of a 10,000 m² canopy
at a height of around 40 m above the ground, were the
biggest challenges regarding formwork and scaffolding
operations for the project.
High Quality Demands
The buildings of the National Library of Greece and the
Greek National Opera are located behind a man-made
hill in which the sloped roofs of the buildings form, as
it were, an extension of the incline.
The highest architectural concrete quality is required
for the numerous walls and columns of the structures.
All buildings are characterized by their distinctive geom-
etries, including inclined slabs at heights of up to 31 m.
Before construction started, concreting operations
were trialled on-site using the Peri VARIOWall Formwork.
This was necessary to determine the quality that could
be produced under the conditions found on the job-site,
to develop and ensure the technical procedures, as well
as to provide training for the personnel.
The surface quality, which was defined in this process
as the "reference surface", was agreed as the binding
standard for the works.
The formwork comprised VARIO elements with dou-
ble formlining skins. In order to eliminate impressions
of any kind, FinPly formlining sheets have been screwed
on from the rear.
The joint arrangement and position of the anchor
points were planned by Peri engineers in accordance
with the design specifications. In some areas, self-com-
pacting concrete has also been used; here, the formlining
joints have been additionally sealed with silicone and
taped to ensure the best-possible joint formation.
For the higher walls, the wall formwork is positioned
