Se estimated disturbances in different parts of the School during the spring below.

Construction work week 12 (22 – 26 March):

  • Curtain injection
  • Floor cement injection
  • Excavation work

Construction work week 13 (29 March - 2 April):

  • Curtain injection
  • Floor cement injection
  • Excavation work

Construction work week 14 (5 - 9 April):

Please respect the demarcation of the work area!

Project information for the period until June 2021.

During the spring 2021 the information about the project will be updated once a month instead of every other week. These are the planned activities, but of course there is a risk of changes, mainly due to uncertain ground conditions and other unforeseen events.

Mars 2021:

  • Shafting, mounting of beams and jack posts, first level. Low level of disturbing noise.

April 2021:

  • Shafting, mounting of beams and jack posts, second level. Demolition of existing basementsamt. Medium level of disturbing noise.

May 2021:

Shafting, mounting of beams and jack posts, second level. Demolition of existing basementsamt. Medium level of disturbing noise.

June 2021:

Shafting, mounting of beams and jack posts, third level. Low level of disturbing noise.

Estimated degree of disturbance in different parts of the school during the spring.

Explanation of technical terms:

  • Curtain injection is a method used to seal rock in order to avoid uncontrolled groundwater subsidence or leakage into rock shafts. Simplified, this means that holes are drilled in the rock, then the rock's natural fracture system is injected with a cement mortar for a certain time and with a certain pressure. The method seals the sides of the shaft.
    Higher risk of noise.
  • Floor cement injection is done in the same way as curtain injection. The difference is that curtain injection is vertical and floor cement injection is horizontal. The result of these two injektions is a completely tight shaft.
    Higher risk of noise.
  • Stud drilling means that steel studs are drilled down inside the set sheet piles so that they do not slide off the rock but stand securely.
    Higher risk of noise.
  • Shaft, beams and jack posts: The beams is welded to the sheet pile walls. A jack post (a steel post placed perpendicular to the sheet pile walls on opposite sides of the shaft) is mounted on this to prevent the sheet pile walls from falling inwards. When this is done, we excavate about 3 meters before we assemble a new beam level. There are beam levels down to the rock.
    Less risk of noise.
