The project involved the construction of the two connected buildings on the same plot with very different uses; a showroom and a workshop, connected by offices and hampered by the discovery of unexploded bombs on site.
The workshop was designed to be a portal frame building with long spans of steel work that would mean there was no need to rely on bracing or trusses which resulted in a slim roof profile. There was however, one snag in this design, as the slim roof profile meant there was a reliance on columns, which could encroach on the space. This was acceptable in the workshop but needed to be avoided in the showroom.
Maintaining the integrity and aesthetics of the building were important to the client in this case, so we carefully considered the movement of the building during this phase. The lack of internal columns and the inclusion of eighteen-metre-wide windows, necessitated the use of fabricated steel trusses to support the roof. We had to pay careful attention to the behaviour of the trusses under wind and snow loading to prevent damage to the ribbon windows.
These trusses had to be very stiff both laterally and vertically to ensure the structure’s shape was maintained. A number of options were explored, and we made full use of the bi-directional links between our analytical and drafting software to ensure that this process was as efficient and seamless as possible.
