The detailed planning developed by the Peri
engineers on the basis of the Peri UP
Modular Scaffold meets all requirements,
and the system can make full use of its
Through its consistent metric grid di-
mensions, Peri UP is extremely flexible in
all three dimensions. It can be optimally
adapted to suit both the complex forms as
well as accommodating the varying loads
– in the system, each leg is positioned to
exactly match the geometry and loads to
A further advantage for the construction operations:
due to the high rigidity of the ledger connections, large
units can be moved by crane.
The up to 40 m high Peri UP Stair Towers integrated
in the load-bearing system provide quick access to the
working areas at great heights.
The required working areas for the assembly opera-
tions under the canopy were created with UDI steel
decks which provide a gap-free surface throughout.
In all areas, end-to-end toe boards, guardrails and
integrated access provide maximum safety and thus ef-
ficient working activities.
For the fine adjustment of the prefabricated roof
module positions, Peri developed a special component
with which the panels can be moved quickly and
accurately in transverse and longitudinal directions by
up to 5 cm.
Due to the high risk of earthquakes in Athens, earth-
quake resistance also has to be ensured during the entire
Consequently, the Peri UP Shoring is positioned on
specially-designed floating supports that minimize the
movement of the scaffold construction in case of an
The size of the project and the tight construction sched-
ule created a very special logistic challenge regarding
For forming the immense wall surfaces within the
whole complex, large amounts of system formwork are
in use on the construction site at the same time – the
same applies to the huge quantities of shoring.
A Peri project manager has ensured here the neces-
sary communication and coordination as he supports
the site management in helping to maintain the strict
An Iconic Building
The SNFCC will house the National Library of Greece as
well as the Greek National Opera. The whole complex,
which also features the Stavros Niarchos Park, covers an
area of almost 21 hectares.
Italian architect, Renzo Piano, was awarded the con-
tract after an evaluation procedure lasting more than a
year against competitors from around the world based
on his "vision, intellectual curiosity and a historical and
geographical understanding of the project’s location and
