This morning (Tuesday, 22 December 2020) we discovered that the builders have poured the concrete.
We are not happy because builders didn’t rectify the issues and didn’t tell us that they were going to pour concrete.

Also, our consulting engineer identified that the bottom reinforcement at the back is exposed along with 50% of the bar chair:

This will corrode and there will be major issues developed. The contractor in now required to jack hammer concrete out at the rear and undertake rectification works. This was something I had raised during the site inspection. The works as they are do not comply with code requirements.
