High Quality Concrete
The finished shell at the construction site "WA 3.2" for
100 condominiums is being created by the construction
firm S.Pöttinger GmbH &Co.KG
as a monolithic concrete
For purposes of quality assurance, the entire con-
struction process is being supervised by the investor,
Terrafinanz, though an in-house project manager.
In order to meet the high quality requirements and
the tight schedule, almost all the concrete structures
were formed with formwork systems from Paschal.
As a regular customer of Paschal for the past thirty
years, with over 3,000 m² of its own Paschal formwork
systems, the site manager Alexander Marrero and the
foreman Thomas Greier are very much familiar with the
formwork from Paschal.
To create the concrete structures, foundations, col-
umns, walls and elevator shafts, the systems Modular/
GE, LOGO.3 and the column formwork Grip are used.
For forming the rounded walls of the enclosure of
the underground parking garage entrance and exit,
Pöttinger rented the Trapezoidal girder formwork TTR.
For concreting the 8 elevator shafts, the contractor
is using 3 sets of the LOGO.3 dismantling inside corner
Formwork Systems From Paschal
Since the large construction site on Hochäckerstrasse is
classified as a "B2 Construction Site", there are specific
requirements for the concrete work in terms of super-
vision (external inspection) and installing the
As the results of the concrete elements formed in
July 2015 demonstrate the component dimensions and
the concrete surfaces that have already been delivered
by the project manager on behalf of the client.
For purposes of fire protection, smooth smoke ex-
traction shafts were necessary from the underground
garage to above the roof.
For the sake of separation, the concrete shafts follow
along the exterior facade between two balcony
In order to dissipate the smoke quickly through the
roof in the case of a fire, the insides of the concrete
shafts have to be smoother than SB 3 exposed
Pöttinger met this with selected standard formwork
elements from the Paschal LOGO.3 system.
Formwork vibrators are used on the outside for com-
pacting the concrete, since the walls are only 12 to 16
Despite tremendous pressure in terms of deadlines
and quality standards, the contractor is progressing with
the refined shell with around 7,000 m³ of enclosed space
and 8,500 m³ of C 30/37 ready-mixed concrete in ac-
cordance with the agreements.
Next comes the construction phase WA 3.1 with 60
residential units, along with underground parking
