My Home Sayuk Tellapur, has handover actually started?

My understanding is that with a project of this size, handover is almost never a single event, and I too would like to know what the current position on the ground actually is; kindly advise if anyone has a reliable way to verify it, since I would not want to rely on what the sales team says either. My related worry is what happens to the residents association in such a case. If occupancy spreads across towers over many months, the association is effectively run by the builder for a long stretch, and the early residents have very little say in how water supply, tanker arrangements and lift maintenance contracts are decided; two friends of mine in newer gated communities have had exactly this complaint. We are shifting from Vijayawada and are looking at Tellapur and Nallagandla, so I would be grateful to hear from anyone who has seen how a large phased project handles this.
