Bung:

 

kryptonjohn:

 

 

 

The code is no big deal - no permit or consent required, 150mm H5 rounds at least as deep as high at 1.2 centres and backed with 200x50 H4, with drain coil, sleeve and scoria back fill should do it.

 

 

 

I may be overly cautious but if your 30m was in a straight line I'd be tempted to put more posts in. Mitre10 quote 150 @ 1200 centres but most other examples are 900-1000mm.

 

When my neighbour had his walls done on a hillside site they saved on labour with the drainage by using recycled porous blocks of polystyrene behind the planking rather than 100% metal.

 

 

Yeah I think you are right, @Bung ... would hate the walls to start shifting - I think better to estimate on 900 centres for 150mm poles... or use 200mm poles at 1.2 centres and commensurately larger holes and more concrete. Will have to do the sums on that trade off...

Do you actually have a quote, or are you basing your figures on broad spectrum estimates for ballpark figures?

It's too early to get a quote - ground's too soft to get machines in. Have had an estimate that was a bit less than the higher numbers that I've seen bandied about.

 

As one someone said here, it's natural to be conservative on these numbers due to the unknowns.

Just finished getting a 50M long retaining wall done. Heights varied from 1.2m to 0.4m. Worked out at just under $300 square meter. 125 x 125 posts at 900mm centres, 150 x 50 top cap, 200 x 50 T&G, drainage, mowing strip, and a 3m x 4m concrete pad for a spa pool.
There was a reasonable amount of digging clay by hand as a digger would not get into the space. Concrete came in from a concrete truck and wheel barrowed to where it was needed. 2 guys most of the time, with a third to help with the digging and moving concrete.

Still some work for us to do with laying new lawn, and moving that big pile of dirt so the back of the property.

Wow what a job. Digging clay by hand is no bargain.

Jeez concrete footings too. Really nice. Care to share who did it? Are they in Auckland?

Looks very tidy.  That bottom step with the knot, (which looks to be macrocarpa?), looks a bit ropy, as that may crack off fairly quickly. If it is macrocarpa, it rots pretty quickly when in ground contact. I would have probably done it in pine like the  retaining wall so it blends in. Not unless that is just formwork.

Watching this thread with interest. As I have some big retaining walls planned at my house. They will almost certainly be over the height limit that means you require a consent. So I will have to get the council involved. Although in Auckland, it seems like the council just ask for the producer statements and check you install any needed handrails. So very little benefit provided by the council in relation to the costs they charge.
