What is the purpose of the structure/ project?
Design and supply Large Span LGS Trusses.
What was the brief to the architect?
The architect brief the contractor that the trusses needed to have clear span of 17.5m with HVAC services.
Was the project envisaged in steel from the start? If not – why was it built in steel in the end?
The project was originally put on tender for Timber trusses and due to the large span and HVAC services the LGS Ultra Span System was introduced to be a more viable solution and came out to be the more cost effective method.
Give a brief description of the structural framing. What type of sections were used (e.g. hollow, cellular, I beams etc) and why?
the eaves sprockets needed to be mildsteel and by using h-beams to support the sprockets that is made out of ipe steel beams was used to speed up the process of getting the structure up and to do sheeting before the walls for the beam fill was did.
Give a brief description of the cladding process (complexity, difficulty, innovation etc)
Saflok 700 is used for the 5deg roof and the long valley.
Give a brief description of the Light Steel Frame Building element of the project. (Notable features/ achievements made possible by LSFB)
Due to the use of the ultra span sections the trusses weight and ease of erection made it possible to manufacture and erect the trusses without a crane.
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.
The manufactoring of trusses took place on the slab and due to limmited space on site all sections where pre-cut and could be caried in pieces to the slab and manufactured on the slab and lifted to the ringbeam by hand.
What is special/ unusual/ innovative/ aesthetic about the steelwork/cladding in this project?
The limmited space and using mildsteel members to for the eaves detail made it possible to erect the structure in cost effective and timely why.
How did the project team work together (e.g contractor involved early, challenges/ ease of communication etc.)
The main contractor and ecostrut worked together to make this project a success in all aspect from manufature to the complete erection of the structure.
