I saw an Australian who really did a 30m span, truss @ 5m spacing with slope ceiling some more. Weight ratio is just 8.5kg/m². This kind of weight ratio I usually see it in lightweight truss for span < 12m.
It's really challenging in estimating. I think this ratio is important to cross check engineers design as well not only important for quotation and lobby for jobs.
Just wonder any GURU out there willing to share their rules of thumb. Or is it more appropriate to get it in m run/m² then we work forward? Just my thought.
