Spacing requirements for stumps, bearers and joist in VIC for a deck subframe please?

[Dean38]

Hello everybody,

I need to complete a deck and i don't know the spacing requirements for each of the stumps, bearers and joists.

My deck will be 3390mm x 3720. It will be free standing, low lying and will be spaced about 40mm away from the house for termite inspections.

I will be drawing up the plans for the council to approve as its over 10m2 and also building it myself.

It will hold the 8 seater table and possibly the bbq if space permits.

My guess is:
12 stumps, 4 bearers and maybe 8 or 9 joists.
100x100,190x45,90x45

There will also be paving either side of it leading to the garage and to the back yard. Its like a 'T' piece configuration.

Any help would be appreciated.

EDIT: what is the minimum ground clearance from base of bearer to ground in Victoria to pls? :B

all good nearly,
i read a post after mine and basically some info http://www.renovateforum.com/f196/questions-bitumen-joist-bearer-spacing-104007/
I need to go 400mm spacers on the joist due to the 90x45 im using but i still need to know if the amount of bearers is correct...they will be 190x45 in size across a 3410mm span.... My guess was 4, please correct me if im wrong.



cheers

re-read the span tables and i figure 1 bearer every 1100mm across 3410mm....so 4 is good.


anyone know how much space is required under the bearers to ground......?

In Geelong the minmum is 150mm. Not sure that applies to all of VIC. A local residential designer or your council's Building Department should be able to advise for your area

A freestanding deck can sit on the ground . .. so long as you use the right materials

I spoke to another person at the council and she advised the same thing, she also confirmed that for the whittlesea shire...150mm clearance is required for stumped decks.
I changed my plans to have the deck sit on the ground basically....all good now.

Thanks all for the replies :U
