Information about the construction work

On this page we share information from Akademiska Hus and Serneke about the construction work in the near future. New information comes every two weeks and if needed more often.

Information about construction work week 4 - 7 (25 January - 19 February):

The ground work is progressing as planned and as many of the steps take a long time to complete, we have decided to publish project information monthly instead of every other week. Should there be changes in the planning, we will publish information about this.

Construction work week 4 (25 – 29 January):

  • Excavation, drilling and curtain injection

Construction work week 5 (1 – 5 February):

  • Excavation, drilling and curtain injection

Construction work week 6 (8 – 12 February):

  • Excavation, drilling and curtain injection
  • Stud drilling for the sheet piles

Construction work week 7 (15– 19 February):

  • Excavation, drilling and curtain injection
  • Stud drilling for the sheet piles

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.

January 2021:

  • Floor cement injection, low level of disturbing noise.

February 2021:

  • Floor cement injection, low level of disturbing noise.

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.

Explanation of technical terms:

  • Jet grouting is a method used to reinforce soil in connection with excavation and foundation work. The method involves drilling down a drill rod with a grouting monitor into the ground. Then the nozzle sprays a mixture of cement and water into the ground under high pressure (400–500 bar), at the same time as the nozzle is rotated.
  • 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.
  • 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.
  • 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.
  • 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.
