Indian Railway Station Redevelopment MEP — Amrit Bharat + RDSO + NFPA 130 + NFPA 92
A Tier-1 Indian railway station redevelopment (150,000 daily footfall, 8-platform) demands ₹455 Cr MEP capex covering concourse atrium smoke 4.8 lakh CMH + platform spot cooling + retail mall integration + multi-level parking smoke control. Amrit Bharat + RDSO + NFPA 130/92 + NBC + UIC govern. Three failures: station + retail-mall smoke shared producing fire-spread risk through smoke path, heritage facade dehumidification missing causing stone erosion behind retained shell, footfall designed at average instead of 2-3x festival peak.
Indian Railway Station Redevelopment Programme MEP framework
The Amrit Bharat Station Scheme (1300+ stations) + IRSDC Station Redevelopment Programme + Major Stations Modernisation (Mumbai CSMT, Delhi NDLS, New Delhi NSCB, Surat, Gandhinagar) are the largest mass-transit MEP exercises in India. RDSO Specifications + Indian Railways General Conditions of Contract + NFPA 130 (Fixed Guideway) + NBC 2016 Pt 4 Annex F + station-specific access + commercial integration shape the brief. The MEP signature challenge is footfall surge (50,000-300,000/day) + commercial mall integration + station-level smoke management + station-shop fire-load + heritage facade retention.
Tier-1 station redevelopment MEP scope — 150,000 daily footfall, 8-platform

| Platform (covered) | natural ventilation + spot cooling | — | 3 MW per platform | 120,000 each | 22 |

Three Indian station redevelopment MEP failures
- Station + retail mall on shared smoke management — station smoke control + above-platform retail mall need separate smoke fans + interlocked evacuation logic per NFPA 92 + NFPA 130. Sharing means commercial smoke can spread to platform exits during retail fire.
- Heritage facade dehumidification missed — retained heritage shells (CSMT Mumbai, Egmore Chennai) need micro-climate control behind facade to prevent stone erosion + interior dampness. Standard retrofit AHU does not handle facade thermal break.
- Footfall surge not modelled for festival/summer holidays — Indian stations see 2-3x footfall spikes during Diwali + summer rush. Design at average pax/year fails. Use peak-day analysis + 1.5x diversity buffer.
