A tape measure in the photo for reference on close ups is advisable,etc,etc Also photos should be taken as the structural drawings are read. eg, Footings looking down, Anything above the ground from beneath looking up. Structural drawings are the opposite to architectural drawings...

I just wanted to re iterate my concern - I’m just digging the hole, that’s it. per your comment, in a typical scenario, the duration between digging the hole, inspection and concrete would be substantially shorter than what i’ve done - by pulling the trigger early on the digging, am I now at risk of the existing strip footing being undermined? Only questioning as we’ve dug right next to it, per the proposed location of the new pad, at a depth lower than the existing, again per the engineering (the hole = 400x650x550)…. Should I be filing it back in with dirt, compacting and waiting until the day it’s actually required? Once the concrete is in, it’s not an issue, the concern is the extended period prior StructuralBIMguy Re: Pad footing excavation and existing footing 7Jan 01, 2022 4:38 pm I wouldn't be filling it in, The guys will trim and clean out the bottom on the day of the pour hth Designer,Engineer (Civil,Const & Envir),Builder,Concrete & Masonry Contract.Struct Repairs No one can give you a meaningful answer without looking at your building contract, what happened on site and who designed your house You should get experienced building… 1 10463 Hi there, We’ve recently had plans approved to add a 1st storey addition to our existing house for a growing family in Sydney.
