What to spot about construction quality on Pune site visits

Khinvasara Aranyeshwar Park Phase II – I'm finally taking the plunge after years of renting, fed up with landlord drama and rising rents. I'm doing my due diligence on new projects, but honestly, the construction quality worries me. Friends who bought recently had issues with plaster cracks and seepage after just a year. During site visits, I'm trying to spot things early – like checking window frames for proper sealing, looking at pipe routing in visible areas, or even just the finish of common lobby walls. Is there anything specific you guys check during under-construction site visits that hints at future problems? Also, how do you verify if promised amenities like the clubhouse will actually be usable, not just a showpiece? And what about maintenance charges versus actual service quality post-possession? Hope this helps someone else looking to buy.
