Deck

No they are pressure treated 4 x 2 at 400mm centres and the noggins at 1200mm centres. The span is 4metres.

Translation [big grin]

2x4, 15-3/4" oc, blocking 47-1/4" oc, span 13' 1-1/2"

The framing would have never past an inspection here. Not because of the craftsmanship, it would not meet the load requirements.

That's what caught my eye. (They would have to be 2x8's here.)

I would have run the joists the shortest way! Does any one use mini galv hangers or is it just me!! Then you could of had nice long runs on the decking boards...?
Lets hope gran doesnt have a monster rave on there. You could have broken the span with stock bricks and dpc.

Had to do a deck the other day and it was composite. 50% wood and 50% plastic.....awfull. :'(  hope I dont have to use it again. Was like cutting steal and the dust was noxious.

2 x 8 wouldn't have worked in this deck as there is a concrete path and then a Tarmac area under where the deck is. Also the client wanted the deck board almost level with their patio door and there was a concrete path outside the patio door so unless I dug all that up I wasn't going to use anything more than 4 x 2  [tongue]

I know what your saying about running the joists the short way buy that would have meant the deck boards would have been orientated the wrong way. The client wanted the lines on the deck boards to run straight out from the patio door.
 
4x2's undersized and full of knots.  Granny, if she tries to escape had better slide across on her tummy the way I used to do when crossing thin ice  ::) on shortcut to get home late for chores.

Funny enough Tinker she is a woman in her 60's who's going to be using this as an extension to her sitting room. She's a very out doors person. Her back garden is like a zoo  [eek] 4 x 2 was plenty good enough in this situation as I installed plenty of blocks while laying the deck boards and there is not one single spot where the deck moves.

She would get along fine with my Dearly Beloved who has been 39 for two years less than i have. I guess that makes he 37.  ::)  She gets out in her garden and when her back starts giving her problems, she limps back into the house moaning as she fixes her cup-o-tea.  Once the tea is drained down her gullet, she is right back out there again, pain or no pain.  She won't let me do anything in those gardens except to carry the humongeous buckets (baskets) of weeds out to the woods.  I darned well better move them when she suggests, or i will hardly be able to lift them, let alone carry them down the steep hillside.  [oops]

OK on the blocking.  Good move

In my area of the world it is OK with building inspectors to use 90x45 (4x2) as deck bearers as long as they are laminated. That is running side by side and joined with fixing such as battern screws.
 
I don't remember what the building code called for when i did a few decks, but my carpenter friend told me to never put two outside deck joists side by side unless there was a space between.  Even with treated lumber, they would begin to decay.  I am guessing the weather/climate swings might be a bit more changeable here in New England than in a lot of other places in the world.

Hi again Tinker,

I was referring to bearers not joists.  [big grin] Many including myself also place rubber/plastic flashing on deck bearers and joists to keep out moisture. Not totally foolproof but does help. Our temperature range is from around 0C to 40c plus over the four seasons with around 600mls of rain per average year.

Addition

Just went outside and photographed under deck I built 4 years ago.

Joists are 12045, bearers 2x9045, deck merbu 9018. CCA 120 is now hard to get, 140 now standard.

Here, it would not have passed an inspection. Would have ended up digging it out anyway.

I don't recall what the arguement was about, but i was constructing something in a neighboring town where the BI had a bad rep with outsiders.  I had about exhausted my arguements, so i went to my truck and brought out the code book, which, as having been forewarned, just happened to have been in the glove compartment and just happened to be opened to the page needed. My solution actually exceeded both the town and state codes.  I had a tendency to over build in a lot of situations, and this happened to be one of those problems.  The BI did not even venture to peek, but looking me straight in the eye, he said, "Young man," with strong emphasis on the 'Young' part, "In this town, I am the the code."  I did it his way.

A year or two later, i became a resident in that town.  From that point on, he never saw anything but good in my work.
