Office Building in Järnbrott | VBB122 | MPSEB | October 2015

AIM OF THE PROJECT

Provide a proposal for a structural system for a two-storey office building.

The proposal should fulfill all requirements set by the client and other stakeholders

while being economically viable and create an added value for the stakeholders of

the project.

FURTHER INVESTIGATIONS


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)?

Thank you for your attention!
