Parents in Hyderabad: How to check under-construction quality?

Honestly, I'm finding this home-buying journey way more complicated than I thought. We're upgrading to a 3BHK in Hyderabad, kids ke liye safety aur good construction quality top priority hai. Currently eyeing Sattva Lake Ridge, among others. Site visit pe sab achha lagta hai, but under-construction projects mein kya dekhein? Builder sales reps toh best hi batate hain.

Practical tips for judging quality on site needed.
