Purpose:
NPK (New Building Mental Health) is a new hospital which
was built directly south of the existing hospital in
Kristiansand. The area is known for being sensitive
quick clay and the area has traces of possibly earlier
quick clay landslide.
Design:
An area of approximately 5,400 m² was lime stabilised. The
KS piles were set in ribs and single piles.
Execution:
The area was stabilized with Multicem 50/50 and a
mixing quantity 100 kg/m³. Due to great danger
for pore pressure measurement there was a lot of movement
rig in the area. The work was carried out with the help of two
KC rigs.
The work was carried out under the auspices of YIT Infra Norge AS.
Competence, personnel, machines and equipment were
transferred to Consto Dambygg AS in 2021, before it was
sold on to Seabrokers Fundamentering AS i
2022
