The building is around 250m² with lots of shopfront opening divided by 220mm wall fins. LSF wall panels and trusses and roof panels. The most changeling was the soffit boxes above NIB wall to take the trusses. Roof overhang cantilever of 1200mm.
The cantilever entrance soffits and horizontal beams to look like cast concrete. The support structure for these needed to protrude into the truss void by approximately 2.0m to allow for the cantilever.
Was the project envisaged in steel from the start? If not – why was it built in steel in the end?
Yes, the architect has previously worked with LSF.
Give a brief description of the structural framing. What type of sections were used (e.g. hollow, cellular, I beam etc.) and why?
A standard frame-cad LSF lip channel section was used for all walls and roof structures. 90 x 40 x 0.8mm LSF Section.
Give a brief description of the cladding process (complexity, difficulty, innovation etc.)
The cladding process is standard flat fibre cement, however, most of the building consists of glazed shopfronts. The entrance canopy’s and soffits were a bit challenging
Were there any challenges in the fabrication of the project from the engineer’s design – if yes, please tell? Tell more about the fabrication and erection process if it was complex, difficult, innovative etc.
Roof overhangs on the sides needed extra support in the roof, panels on 4 corners as well. This made them quite heavy.
The cantilevered soffit beam detail at entrances required some extra design and solutions to achieve this.
What is special/ unusual/ innovative/ aesthetic about the steelwork/cladding
in this project?
The interesting boxing to entrances and soffit beams.
How did the project team work together (e.g. contractor involved early, challenges/ ease of communication etc.)?
Shospec priced as a sub-contractor at tender stage, we had no involvement in the original design process.
