Certainly gives me a lot more to think about. I'll probably adjust posts so that they're less than 1500mm apart, and reduce joist spacing to about 400mm to build in a bit of leeway and added strength. Plus reducing the joist cantilever to 300mm or less. Also edited the links to the plans so they're at full size and actually readable http://tim-and-tina.com/deckplan1.jpg http://tim-and-tina.com/deckplan2.jpg Tomorrow is clearing the site, pulling up all the weeds, removing all the bricks the builders have left as a temporary step top the back door, and hopefully marking out lines and making a test posthole to see how deep the footings will need to be. And I've had one thought nagging at me, often it's specified to use two 90x45 glued/nail/bolted together as a bearer (and a single 90x45 for a joist) - is this because it'd be stronger than just a plain old 90x90 post? It would be good to keep the bearers and joists using 90x45 because it makes ordering materials a bit simpler, and the dimensions of the deck will be 200mm - 90mm bearer, 90mm joist, around 20mm decking, plus 100mm or so of space underneath the bearer if I have 300mm to work with.

It took a lot of research at the time but the right way to do it when nailing seems to be have the grains for each piece run in opposite directions. Nail in two rows. Nail spacing in each row no greater than 2 x the height of the bearer (so 180mm max) and drive each alternate nail from the opposite side. Min nail diameter is 2.8mm? (I used 3.75x75mm cause I had a box floating around). One of the things i forgot to mention when looking at joist span is it isnt centreline of bearers but from the bearer faces (slide 25 of that power point link). So your joist span is 1410mm (when looking it up in tables). Looking forward to see how it all comes together, hopefully the weather stays good for you! Re: T&T: Please assess/critique our deck plan - need advice! 10Dec 27, 2011 3:09 pm Just a little tip that I like to do. I use 90mm U stirrups so the bearers are locked in between the flanges of the stirrup and then bolted together. They can sometimes be little tight to get in place but I just like the idea that the bearer is really held together. Single sided stirrups are easier to install and once they are bolted on are probably just as good, I just like the additional peace of mind from the full U stirrups. I also like to stitch the bearers together with 75mm buglehead batten screws after nailing. They are fairly cheap and are quick to put in but will never pull open unlike nails. You probably don't need them but when I build a deck I like it to last. The reason you use 2/90x45 is basically cost. 2/90x45's are much cheaper than 1/90x90. It is also much easier to find long, straight lengths of 90x45 than 90x90.

Prepared the site last week, and got cracking on things today (wrong day for it, too damn hot!) and got two bearers installed. I decided to overengineer things just a touch to make sure things won't fall apart in a hurry. There will be 4 bearers, 3 with 5 supports and one shorter one with 4 supports. Brackets/supports are about 1m apart under bearers. Each bearer just less than 1m apart. Joists will be 400mm spacing. Bearers are 2/90x45 nail laminated, joists are 90x45. Decking will probably be a 20mm Merbau. There's 100mm clearance to ground under bearers. Will use some dampcourse to cover the tops of bearers/joists (far cheaper than "protectadeck"), triplegrips to secure joists to bearers, and stainless steel screws for the decking. Will also do a picture frame border, once I think about it some more and figure out how that works (extra joists at ends to support the border + decking I figure) Brackets installed Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Bracket detail - these things are great as they're adjustable even after being bolted in!

Will wait for a cooler day!

I stapled down the dampcourse on the bearers and joists also and it seems to work a treat. Certainly pick up lots of good things surfing forums. Overengineering is never a bad thing, you save so much on labour the extra material cost isnt much and its always better to err on the side of caution! Keep the photos coming, always helps people following with a similar project. Good luck with the rest of it! Re: T&T: Building our deck - work in progress 14Jan 13, 2012 10:13 am Stupid melbourne summer - 40 degrees one day, 13 the next with snow and hail! Can't get much progress done, but halfway with laying the decking. Here's my supervisor doing a check of progress; Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ So far one snapped smart-bit drill head buried deep in a joist - will have to patch and hide it before staining the deck later. Otherwise a few scrapes and splinters and a sore drill-finger but no major casualties *touch wood*!

Good idea staggering the screws in the merbau too. I have a question for you regarding the footing that is existing between the house and the brick column at the far corner. I'm quoting a deck for a customer in Whitehorse and was concerned about what I think is a strip footing in the running between the house and the column. They have just had their house completed by a big builder starting with Met ending in ricon (apparently that name is offensive??) in the past few months and were unable to tell me how deep it actually was, if it is a footing at all. Did you have similar footings or was the slab poured before you moved in? If you'd like a bit of advice regarding the best oils to use I highly recommend using products from Quantum. It may seem like overkill but for new decks that the customer wants oiled immediately I use three products, sap strip (to remove the existing natural oils still in the timber), decks prep (to clean the merbau before oiling), then the oil of choice. If you have any questions regarding their products, quantum have some great staff that are a great help. Best of luck mate! Re: 16Jan 17, 2012 11:33 am Eastern Decks Looks great Tim!

Hi - thanks for your feedback Pretty much finished my deck now, just got to get one short piece ripped to 60mm to fill in a small gap, fit 5 decklights once I find a suitably sized holesaw or spade bit, and fit the last trim board. Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ The strip footing is at least 600mm deep - click here - http://tim-and-tina.blogspot.com/2010/01/day-29-concrete-piers-completed.html as it shows the depth. It has to be pretty deep and strong since the brick pier in the corner holds up the roof over the outdoor room, so I had no concerns about bolting brackets onto it for my deck We went to the Cutek distributor in croydon yesterday to get some samples of stain - what do you think of Cutek as it gets pretty good reviews too. My wife also likes some of the Feast Watson stain colours too.
