Yes, but when a customer wants a wall say 1.2m high wall and doesn't want drawings so you spec it yourself without getting an engineer involved whether you use blocks, sleepers, timber stakes what's an acceptable timeframe didn't know if there was a timeframe as you could get a phone call in 10 years time?
If they don't want to pay for drawings then ideally use drawings from another job but explain to them that ultimately its on them

How long do you think is 'fair' to give as a guarantee for a retaining wall? 12 months, 12 years? Obviously, everyone stands by their work but what's an acceptable amount of time?

Not too sure but any issue and your fubared you need indemnity insurance as your specifying the works so your public liability will not pay out if the wall collapses or worse.
With something like retaining walls I'd imagine they would come with a long guarantee

Agree guarantee period upfront with the client before you start and if no engineer is involved air on the side of caution when you spec the wall. Keep your arse as covered as you can

That won't cut it .... over here we have a 10 year insurance which you are obliged to take out as a artisan and it's expensive. You can put what you like regarding the customer accepting liability but it comes back to you at the end of the day.
im guessing if we haven't got an engineer involved then our insurance will f**k us off .... its all tosh.

I had this customer had a failing retaining wall, engineer designed repair customer said that’s too expensive. Engineer said well you could do this but I’m not signing it off. Customer went with cheaper option think it was 19k vs 24k anyway few months later client was like I’m selling the house can you send over guarantee for the wall repair. I was like nope, you opted to ignore the engineer I’m not giving you anything in writing. He threatened to sue me but never heard owt.

if they want a guarantee then they must pay for an engineer - end of .... otherwise forget it ... or spec it themselves

yeh .. a builder had done the wall (which was total crap) .. and Tom'd said it wasn't up to being backfilled ... should've walked, but started filling it and collapsed on his new m/c ... don't think they ever caught up with the builder :(

The right to refuse has stopped me several times!!
I have to confess that I am a Gabion Wall man. Happy to do 1m high, 1.5m if pushed, or 2m if really required but at that point we are staggering back. Beyond that get it designed. Any walls in masonry I will not design. Seen too many failures!!

There was a 3m high H block wall perpendicular to the rear gardens of the houses below, no access to below.

engineer spec was remove and redo with cast in situ.

compromised spec was full excavate 1.4m behind wall, mass fill new footing tide in to old and L bars at front face, drill 50mm weep holes every 1m, install pipe through, then tide existing block wall in with load of screw in V ties the built new block laid flat back face to it and filled with concrete in 450mm lifts. Then clean gravel behind and muck away fill. Awkward Job with no room for anything.
