First time poster! We had a high retaining wall built around the property (has a slope) as part of our new build. The wall was included in the contract (HIA) by the builder and they took control of the process. The wall is made up of concrete sleepers and went through an extensive design process by the structural engineer with council sign off.
After the wall was completed and the house was being built, it became apparent there was a slight lean to one of the posts and wall sides. The structural engineer worked with the builder to remedy with some reinforced piers and then a form 13 issued.
When speaking with the engineer he mentioned that the drainage wasn’t completed as per the specifications on the plan and it could have future consequences on the integrity of the wall. For reference the geo fabric wasn’t correctly applied and gravel was put on the wrong side of the fabric.
This was only evident from photos that were taken at the start of the wall build.
We are due for PC in a week, I’m stressing a little as I want to hand over and move in, but I don’t know what our next steps should be.
Builder says all is fine, and there is currently no leaning or bulging of the wall. But what about in the future if this happens.
Should I put it on the defects list (it would be a big job to rectify and doubt they would do it proactively) or should I wait until we have another problem with the wall and then take then next legal avenues I have?
Any suggestions would be helpful. I absolutely want to move into my house (not connected with the retaining wall) but just can’t get the worry out of me about this wall.
Thanks for reading this far, any advice would be beneficial.
