2005 - Putzmeister

Large construction site
46
Up to 1,500 workers are employed on the
vast site. In peak times, 60 cranes lift the
various loads to the different sections. In a
separate production facility, prefabricated
steel parts are supplied, and the necessary
welding and anticorrosion work is carried
out on site.
Two concrete pump centres ensure
smooth placement of 270,000 m 3 of
concrete
In order to guarantee self-supply with concrete,
two mixers have been set up on the
premises. A MAX BÖGL owned system
delivers the Rohbau consortium with
approximately 250,000 m 3 of concrete,
while the concrete produced by the other
mixer is required for the construction of
the multi-storey car park (approximately
20,000 m 3 ) and also covers the peaks in
demand from the Rohbau consortium. The
mixers also produce self-compressing concretes,
in addition to standard concrete with
strength class C40/50.
construction of the interior, the exposed
concrete, with its natural surface structure,
plays an important role and must be pumped
without interruption. To do this, BRM uses
all sizes of truck-mounted concrete pumps
– from a refurbishing mobile through to a
large boom pump. TB Göppingen or BP
Schwaben's machines are also scheduled.
For the concrete work around the multistorey
car park, pump service provider
SAUSSELE (Besigheim), which belongs to
CEMEX, controls the use of concrete
pumps. Here too, it is usually the maintained
machines from their own fleet that are
set up on both sides of the motorway. With
increasing completion of the interior of the
car park levels, the flexible "low building
masters" with 24 m booms with four folds
are most in demand. Other concrete pump
service providers, such as UNION-BETON
(Ludwigsburg) and GODEL-BETON
(Stuttgart) also provide their machines as
required.

According to information from project
manager Dipl.Ing. Michael Frey, the coordination
with the central pump scheduling takes
place fairly smoothly, taking into consideration
the large concrete volumes and the
number of contract sections. He considers
the fact that his consortium only has to coordinate
with one concrete pump schedule as
a great advantage: "Of our ten foremen, each
one works with his people on a separate construction
section.
Often they all need concrete in the afternoon.
Central scheduling is therefore very helpful
if our concrete mixer is constantly fully
loaded and we want to use the pumps with
the required boom reach at the same time at
the individual sections."

The concrete pump scheduling for the
MAX BÖGL and LEONHARD WEISS
construction sections is carried out by
Betonpumpendienst Rhein-Main (BRM),
Lorsch. The range of concrete work is considerable:
long strip foundations, powerful
bottom plates, floors, girders and circular
supports, external walls and internal
partitions, etc. Above all, in the

Our picture shows one of BP Schwaben's BSF 52.16 H
pumps on field 2 during the placement of 280 m 3 of
concrete. As soon as the bottom plate is completely concreted,
the machine is moved by a few hundred metres,
in order to pump 400 m 3 of concrete into a ceiling formwork.
