We are lead to believe from Electrician that the internal stairs should be installed in the house today. They were being delivered and installed.
I hope to go past tonight to confirm this did happen, as well as check that the alarm cables for the control board have been pulled back through the correct side of the wall, since it wasn’t performed as I advised. I did tell them not to pull anything through and leave in wall cavity. However found out later that day they pulled them through, but the wrong side. So advised site manager it has to be pulled through the other side (and much higher up).
Will check tonight we have internal stairs installed, and then confirm the alarm cable runs have been corrected (not to mention check all of the cable runs have been pulled through, and none left behind in the wall).
