Multi-story steel framed buildings used in conjunction with cellular beams offer flexibility and adaptability for the steel structure. Steel is a common feature throughout the structure provided a faster reaction time than a concrete option.

Hollow precast units were used on the flooring system. These were easily installed and provided for a working platform throughout the construction process. This was helpful in speeding erection time as fewer beams are needed as opposed to the conventional metal decking applications.

Due to the long floor spans cellular beams aided as an economical solution for the structural stability of the floors. If normal beams were used for the flooring system instead of cellular beams, heavier section sizes would’ve been utilized with possible plate girders in some instances. This would’ve been a much costlier steel option thus the economic benefit of cellular beams was shown.


What is the purpose of the structure/ project?

Flagship showroom for KTM & Husqvarna, other retail showrooms & restaurant areas.

What was the brief to the architect?

Motorbike showrooms, workshops and restaurant areas

Was the project envisaged in steel from the start? If not – why was it built in steel in the end?

Yes, upon recommendation of the structural engineer.

Give a brief description of the structural framing. What type of sections were used (e.g. hollow, cellular, I beams etc) and why?

Various cellular beams, H-profiles, I-profiles and hollow sections due to excessive floor spans.

Were there any challenges in the fabrication of the project from the engineer’s design – if yes, please tell? Tell more about fabrication and erection process if it was complex, difficult, innovative etc.

Setting out of column foundations for different floor levels was complicated due to basement excavation and extreme weather conditions.  Erection process occurred in three stages.

What is special/ unusual/ innovative/ aesthetic about the steelwork/cladding  in this project?

By incorporating cellular beams as main mezzanine floor bearers in the  structural design for aesthetic purposes and using the apertures for the H-vacand electrical systems.

How did the project team work together (e.g. contractor involved early, challenges/ ease of communication etc.)
Excellent co-operation.  Every challenge was resolved with professionalism and open communication.
