More pouring…..

15 06 2017

The owner builder gods have been smiling upon me…… since expressing concern about maybe having missed the boat with further concreting and Tasmania’s fickle weather, the frosty and rainy weather went on holidays long enough that I decided to persevere, and it’s all paid off….

shower grates

Mind you, it wasn’t without the odd thing going wrong. As Glenda and I reinvented the bathroom layouts, I had to wait for several days for the new grates we are going to use in the shower area before I was able to finish the second spider (see above link). I ended up buying two of these online for $200, while Bunnings were selling them for $300 each…… always shop around!

While waiting, I made three of the four pipes that run into the riser. The riser was in its position, in the middle of the bathroom mockup in the shed, ready to go; once the fourth pipe was carefully glued together, I assembled the spider, only to discover later that the riser had been sitting for days on the floor upside down……… Sacré bleu! I thought I’d worked a way to get away with it, even dragging it up to the house site for installation, until I realised that the riser is moulded in such a way that all those pipes fall to the fitting (it’s only a two degree fall, but it’s important!) and that now all those pipes were going uphill…… and as we all know, water does not run uphill!

I really hate stuffing things up, but I had to go and buy another fitting (50km return trip and $35 later..), destroy the original one, and refit the entire thing properly. I’m getting really good at problem solving.

waterproof membrane in place

I re-hired Caleb to do my heavy lifting and unload another couple of tons of crusher dust off the ute to cover up all those bare dirt patches between the trenches while I went to work putting them together.

There’s a lot to think about. I almost forgot to glue the outlet pipe from the second bathroom, and had to dig it up, by hand. No major drama this time, but there you go. These outlets also have to be lagged with 40mm of foam where they penetrate the footing in case the highly reactive soil I seem to continually build on make the concrete move and break the pipes. It pays to know how

lagged outlet pipe

to read an engineer’s drawings!

Once all the crusher dust was in place, we covered it with the thick plastic moisture proof membrane my supplier sold me, and before you know it, I was ordering another ten cubic metres of concrete.

On the day, I was training Caleb on how I wanted him to rake the concrete towards himself while he stood on the first footing and I inserted the concrete vibrator into the pile of the wet stuff that would land in the middle of the trench. To my amazement, and Caleb’s visible delight, as soon as the vibrator started doing its thing, the concrete came to the end of the trench all by itself, like water in a flash flood……  I tell you, that device is worth its weight in gold! It easily does the work of at least one other man, and maybe more. Mind you, I also had to deal with the end of the machine vibrating itself off, and having to work out the thread was mysteriously left hand – very odd, as left hand threads are usually used to stop things vibrating off! No pressure….  I only had a concrete truck waiting for me to get going again…….

We had two truck loads of concrete in place within just forty-five minutes……. and I had expected it to take twice this long with only two of us on the job!

Now all I have to do is pour a perfectly level and perfectly flat slab on top of the whole thing (after I return from another trip to Queensland to celebrate our fortieth wedding anniversary!), and we can start BUILDING! I really can’t wait to be past this stage; I didn’t want to do this in the first place, but I am saving so much money, it will all be worth it. And to be honest, it’s all turned out even better than I expected, and I am justifiably proud of my handy work……  watch this space.

A good Friday’s digging……

16 04 2017

There must be something in Tasmania’s water that doesn’t agree with the building industry….. I’ve wasted so much time waiting for people to do things for me, it beggars belief. All along, I said that this time, 15 years older and wiser, I would not undertake to do my own concreting at Mon Abri MkII. So I contacted this local contractor, whom everyone around here seems to think is the bee’s knees. He came out, sighted the house site, and the plans, a copy of which he left with. I explained to him what was needed, that I had already ordered the reinforcing, and that all I needed was someone to put it all together……

About a week later, the reo had arrived, and still no quote; so I texted him to tell him the steel was here and asking for his quote. The next day, he rang back with an over the phone quote of $30,000, which I’m almost sure he said included building the block wall… I’m a bit hard of hearing these days, so maybe I got that wrong. In any case, thirty grand being such a very round number, I asked for a written quote. Which took another two weeks. And when it arrived, it was way over the top, with no break down of how much the labour was, or the concrete pumping, earthworks, or anything for that matter, it just lumped everything together, including the steel I already had….. and the quote was now $32,000……. plus $26,000 to build the wall!

I almost fell off my chair…..

That wall building quote works out at $12 a block, which I established was four times the normal rate. So he must have included the cost of the blocks (which set me back $17,000…!) Thirty pallets of blocks is sort of hard to not see….. so what on earth was he thinking about?

String profiles in place

Then to top it off, I visited my friend Dave who’s building a greenhouse up the hill, and the same contractor stuffed the footings up; they weren’t level, causing the block layer to have to trim as much as an inch off the blocks to make the top of the first course level…… By that stage, there was no doubt I was going to have do the job myself, any confidence I might have had at the start of the process had by now vanished. If I don’t save $10,000 by doing it myself, I’ll eat my (very sweaty) hat…..

Having discussed this with Matt next door – who owns his own excavator – we walked over my site with Steve, a very experienced excavator and crane driver who works in Antarctica – I don’t think they hire dodgy people to work there at great expense – and settled on Good Friday to start digging the retaining wall footings.

I had almost (another) month to psych myself up on how we would do this, set the

Depth/Width gauge

profiles up to accurately arrive at the house’s footprint, and eventually started painting lines in the dirt. I also made myself a gauge to measure both the depth and the width of the trenches.

Because the previous excavator driver decided to dig a hole in the wrong place last time, and had to refill it to remedy the error, that part of the bank had collapsed in the heavy rain last year, actually making it impossible to place the profiles where I wanted them. So that had to be fixed first, because a whole pile of dirt and rocks was actually right on top of where we had to dig.

Fixing Trev’s boo boo

Then, because the digger was too far from the bank when digging the small trench under the living space, the spoil had to be put on the ute, which I then had to move and manually unload the two tonnes of dirt with shovel and rake. Like I say, this project will either keep me fit, or kill me..!

the next pizza oven base..!

There was also a huge rock that had to come out where the slab will be, because the top of it was actually higher than floor level. Trev (the last operator) reckoned his machine couldn’t pull it out, but Matt’s excavator is a newer and better device, and Steve had it out in no time…. it might not look like much in the photo, but it has to weigh close to 500kg, and it’s a great find actually, because it’s (almost) big enough to make the base of the next pizza oven on its own, and it’s nice and flat!

The rest of the digging went well, even though working so close to the embankment made things difficult for Steve, who did a great job. It’s so nice to work with professionals, let me tell you…. Now all I have to do is fill the hole with steel and concrete….
