Ambika Florence Park: Under-construction quality check tips?

Budget finalised, loan pre-approved — ab Ambika Florence Park ka site visit plan kar raha hoon. Kids ke liye bigger flat chahiye, 3BHK toh pakka hai. My wife's main priority is a safe aur usable children's play area, not just a showpiece. Jab site visit karte hain, construction quality ke kya signs dekhne chahiye? Jaise walls, plumbing lines, electrical fittings... kaise pata chalega ki aage chal ke seepage ya cracks nahi aayenge? Aur children's play area under-construction mein kaisa assess karein ki woh actually safe aur well-maintained hoga? Koi tips hain ki kya questions poochne chahiye builder se ya kya cheezein note karni chahiye site par? Aap logon ka kya experience raha hai?
