Reply To: Revisions to deck post-tender


This has to be with a combination of Dead Load (load of the structure) and the Imposed Load (Usage Load) and then the addition of the weather outside has a contributing factor. 1.5 kN is for domestic use and 4 kN is for commercial or balconies. I am not aware that internal floors are lower – if anything, the load, I would assume, would be more for internal use as there is much more furniture used and thus the imposed dead load would be far greater…

Karl, just one quick point – do you know why decks joists and bearers are specified to 1.5Kn, whilst as far as I can see, joists in (e.g.) house floors seem to be specified to much lower loads?
