Your thoughts on this

I have a block in Victoria that has 1-6 drop on the land, hard to get to(but a great spot but have been thinking of ideas for the flooring system for a new house.


For stumps use the mega anchor system

For bearers use 150x50x2.0 RHS steel and for joists use normal f17 timber

My theory is that I will get longer spans with the steel(current spans is 2067) but at the moment the plans call for two F17 120 *35 timber for the bearers which will be heavy to deal with and labour intesive with the block being steep


Any thoughts on the matter

Cheers

Find a local structural engineer and tell him what you would like to do. You might get the right information and just pay hourly rate for a short consultaion.

I have done that but I need an engineer who has dealt with the stumps before but he lives a distance from the block .He is unsure about mixing timber with wood

my main question is should i go steal bearers or stick with timber all the way

I don't think there is any problem mixing timber and steel as long as everything is sized correctly. Sounds like a bit of a dodgy engineer.

Timber to timber is probably easier but if the cost is cheaper you need to weigh up the difference. Nailing timber joists to timber bearers is quick and easy.

You will find that a lot of Structural Engineers have a deep mistrust of timber and will also not want to mix timber and steel. There is not an issue with mixing them and if you use RHS sections like the Strammit ones then they can connect them quite easily.
