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
