Hi - am thinking about getting a some retaining wall built - about 30m up to 1.5, high. Looking around it sounds like the going rate to get someone to build it is $450/m and up so close to $15k for the project.

 

I've built plenty of these in the past but have got old enough that I really don't like doing the manual labour any more. OTOH I'd rather spend $15k on something a bit more fun that a wall so had a crack at estimating the actual cost...

 

So I reckon I'd need 150mm round H5 polse at 1.2 centres, 25 @ $65, $1625

 

200 x 50 rough sawn H4 planks, 210 lm @ $6 $1260

 

Some 100mm galv nails, cement, builders mix, hire a mixer, hire post hole borer, draincoil+sock, scoria... say $700

 

5 man days labour - 40h @ $30 $1200

 

Jeez that's under $5k, say $160/m.

 

What am I missing here - that is not even close to $15k?

 

Cheers

Compliance costs - building permits etc

 

 

 

$30/hr, I'm sure they charge way more than that, I would think $45-$55/hr would be their charge out rate.

Where did you get the 30 per hour figure from?

Also, if you can get the 200 x 50 for 6 bucks I might start buying it off you, even with your margin on top.

You'd get a laborer for $30/hr, not a builder.  Also people tend to underestimate time required.

@Ropata - We've been using AWF labourers for $20-$25 and our builder's apprentices/hammer hands are $30-$40 (and they know what they are doing).

 

@gregmcc - no permits or any other paper work required of not exceeding 1.5m high and not carrying additional load above (structures, cars etc). However I can understand a business doing it will carry some overheads. But if that's all then I guess I can save a ton of dough by designing it myself, ordering in all the materials and then just hiring the labour.

 

[edit: note that the labour prices above include margin to the supplier - should be able to save some money with a direct hire of a sole trader)

 There was another thread here not long ago that discussed builders chargeout rates. Council and compliance costs are often blamed, but it depends where you are located.

Yep. I think with the demand vs supply the builders can get away with inflating their estimates.

 

As mentioned there should be nil council/compliance cost due to 1.5m Auckland City rule.

plod: Probably also a 2-3 man job

 

Well there's efficiency for extra hands but my wild estimate is based on man-hours not job duration. I made a conservative guess on the time it takes to dig a hole, brace a post in it, mix some concrete and pour it, nail up the planks etc. In other words, under three days for two guys plus me trying to help without getting in the way!

Sounds like a plan, all you need to do is find a sole trading labourer/hammerhand that's willing to do it for cash and try and pay cash for the materials and do all the driving and material handling yourself.

Maybe get someone to do a labour only contract on a hourly rate, and not on a quote. Any quote will build in a risk margin. So you over all the materials in etc, and get them delivered, and then just get them to do the work. Some builders seem to prefer this. A lot easier than doing all the manual labour yourself.

Drainage chip 6.5m2 450.00, they should lend you a trailer, Drainflo with sock 230.00 plus labour and assuming the pipe wont need a sump and storm-water connection.

Hope it doesn't need a connection. It's not a catchment, just a drain to prevent water build up behind the wall
