FURTHER INVESTIGATIONS
Office Building in Järnbrott | VBB122 | MPSEB | October 2015
The followng topics should be further investigated and designed:
1. Could the columns at the north and south facade be removed in order to create a
lighter impression?
2. The foundation should be designed, number of piles per pile cap. Will there be a
risk for differential settlements between the slab and piles?
3. Will there be a need for anchorage in the foundation? Possible tilting should be
investigated.
4. The glass facade should be designed with secondary beams and connections to
the bracing system.
5. Could the bracing system be slimmed (i.e. are can any shear walls be removed)?
