Raising Floor for Temporary Structure

[JPNortham]

Hi All,

I'm looking at building up the floor height for a film set and was thinking of running beams across the floor, something like 75x150 though I haven't decided yet. Then running the next layer at right angles to it.

Assuming the top layer is around 400mm spacing between beams to support peoples weight, then can the first layer be a little more sparse without compromising the structure?

See pic! (Right side is what I'm aiming for.)

Yeah i would think that would be ok.
I would go for 125mmx50mm (5"x2") joists. 75x150 would cost a lot more and would seem excessively large. Unless weight is a factor....is it ?

is this in a warehouse a studio or similar or domestic setting??
what sort off floor are you on [wood /concrete/other]

I can't see the value in having two layers of joists like this. Nor in using such wide timber
