Inner city location demands
complex logistics
A particular challenge for large-scale
construction sites in inner-city locations
was the limited space available and the
requirement to minimise the impact on
normal city traffic. “Due to the SPRINGER
QUARTIER’s central location, the time slots
when materials could be delivered to the
construction site were very tight. What’s
more, there was only limited space available
on site for unloading delivery vehicles, “
reports Christoph Wieghaus, site manager
for Ed. Züblin AG. Ed. Züblin AG is part of
the STRABAG SE group of companies, one
of Europe’s leading construction services
technology groups.
Since a total of 5,500 tonnes of steel and
about 34,000 m³ of concrete were needed
for shell construction, all deliveries had to
be precisely coordinated to avoid traffic
jams in the surrounding streets. Delivering
the Cobiax SL void former modules to the
construction site over a total of seven loads
was also included in the time planning. We
pre-assembled the void former systems
for the first delivery at the HEINZE Cobiax
Deutschland factory, so the concreting work
could start straight away. For the remaining
six, the individual components were
assembled and processed on site instead.
“After finishing the first mid-layer slabs,
those areas could be used as temporary
storage and assembly space for the Cobiax
modules,” explained Wieghaus. “After preassembling
the void former modules, we
then put them into position on the individual
slab sections.” On the first day using the
void former modules, the Cobiax Team gave
training to all workers on site to ensure quick
and easy assembly. For the laying itself,
plans were drawn up where the slab surfaces
were covered in void formers. These were
drawn up by the Cobiax experts, taking into
account the structural engineering design
calculations, in order to avoid any structural
problems with the slabs.
