    bearer sizing is available in span tables but if you really want fair dinkum quotes get your plans drawn up first. Otherwise most contractors will treat you as a "window shopper" whos most probably going to waste their time.

    The bearer sizes, should be the first column on the left, as all the spans depend on them.

    It also depends on whether the bearers will be supporting walls, etc. Or are they on seperate founds?
    I may be weird, but I'm saving up to become eccentric.

    all exterior walls will be load bearing and using stumps for foundation

    non loadbearing 1800 spacing - 2/90*35 f7 spans 1300 single & 1500 continuous.
    loadbearing span depends upon the roof load width.

    I used 90 x 65 LVL bearers, which is equivalent to 100 x 75 hardwood, and 90 x 45 LVL joists. The max spacing was 1800 in either direction.

    The LVL's were treated for termite resistance. They were marginally more expensive but were long lengths and dead straight and quite light in weight unlike hardwood.

    I would recommend them to anyone.
    Cheers
