Get an independent inspection on your slab, even post pour it can still be assessed for issues. Check your waterproofing membrane , it should come all the way up the side of the slab.

Welcome to the forum
Here's some tips when seeking specific Construction & Engineering advice
1.Associated Relevant Codes are AS 2870 Residential Footing Slabs
2.Take photos of Site work and preparation, compaction results, cross check against Site plan and geotech report
3.Check that the Structural footing Plans, Details & Notes are compliant with 1 above &/or Certified By a structural Engineer as Equivalent or better than what's required in the codes, always ask for engineer proofs
4. Pre-pour Checks to include, Formwork,Finished levels,Reinforcement,joints, beams, WPM, service penetrations,etc,etc
5. Concrete pour Check, include slump,mix, vibration, , etc cross check against Engineers details/notes
6. Note Concrete set times ie Initial & finial, formwork strip, Brick loading,etc
BTW the edge cracking pattern above results form early /rushed formwork stripping.. the question now arises what else did they rush or forget to check?
OT, Subbies and Builders hate having their work checked for obvious reasons, photos taken after the event don't always provide definitive/conclusive answers. In Court you'll need evidence,ie photos with accompanying Data, calculations/ Simulations,etc, hth

Hi first home build here. Thanks in advance. Just got the slab poured yesterday and want to get some advice on the quality of the job and whether I should follow up with the builder.
To late for me to hire an independent inspector before the concrete being poured and I only have some pics before the pour.
And builder is going to start frame work tomorrow, you can see timber has been put on the garage slab. so the concrete is only cured less than 2 days.
I found some issues today,
1. Side or edges of the slab is not smooth, I think this is how it is generally being done? Since they will be covered by brick later on?
2. A crack on the footing or rebate about 320mm long and more than 2mm wide and I can feel the area is not in the same level, should I be concerned.
3. The foundation is not in a straight line, i measured from the edge of the foundation to the edge of the footing. it is 140mm at one end and 160mm at the other end as you see from the pic.
I can't tell u if there are actual issues.
But from your the slab photos they looks fine IMO..
No different then any other slabs I seen.

Have you paid a fixed price for the slab? Keep an eye on the reinforcing, make sure it is per the drawings and has cover from the sides and bottom of the trenches.
