   Episode notes

   Read excerpt

   Delhi-NCR floods every single monsoon — and every year, it's treated like a surprise. In this episode, we go street by street and drain by drain to find out why: a British-era sewer still running under Minto Bridge, a drainage master plan from 1976 that wasn't replaced until 2025, and a written warning about a collapsed sewer in Noida that went unanswered for four years — until someone died. This one's for anyone who's ever waded through a flooded street in Delhi, Gurugram, or Noida and wondered

   Ep. 167 — The Building Was 55 Years Old. So Was The Problem. (opens the original)

   Episode notes

   Read excerpt

   A building collapsed in Satya Niketan, South Delhi, on September 6, 2026. At least six people didn't come home — most of them students. The building was around 55 years old, mid-renovation, with water reportedly pooling in its basement during repair work. In this episode, we trace that collapse back through a century of policy that made it possible. We go back to 1908, when a colonial-era red line called the "Lal Dora" first exempted Delhi's villages from building rules — an exemption independen

   The AI-Optimised Steel Tower India Refused to Build — Rahul Bahl, Krishna Buildestates | Ep 165 (opens the original)

   Episode notes · Neutral tone

   Read excerpt

   A construction firm in India engineered a supertall commercial tower in AI-optimised steel. 17% less steel than a traditional design. 1,000 tonnes saved. Cost parity with RCC — which flips the assumption every Indian developer starts with. The design was never built. Not because the numbers didn't work. Because in 2026, India's construction ecosystem — codes, approvals, market risk appetite — couldn't accommodate it. Rahul Bahl is the third-generation Managing Director of Krishna Buildestates —

   Episode notes

   Read excerpt

   There's a concrete dome in Rome that has stood for 1,900 years — unreinforced, open to the rain, still perfect. Meanwhile, the concrete we pour today has an expiration date of 50 years. We had the secret. We threw it away. This is the story of why. In this solo episode, Rishabh Aggarwal unpacks one of the strangest trades humanity ever made: we swapped a material that could outlive empires for one that builds skyscrapers but rusts itself to death from the inside out. You'll learn: - How the Roma
