New County Hall, Kristiansand

Execution
It is spun with double needles of AZ12-770 with lengths from 12 to 15
meters. These are vibrated and pushed down using our Liebherr LRB 18.
Pillows and inclined braces are installed in stages with excavation since then
must be taken gently due to the danger of quick clay in the area. 

After some months' stay awaiting the installation of the wall element and
floor dividers, we then start dismantling both cushions and diagonal braces
and consoles that have been attached to lean concrete. It required good
planning to remove these inclined braces at 12 meters and with a
dimension of 323 in diameter as there were both partition walls and a cover
above all these.
