The walkthrough is the case study. Public sites can only show so much, here's what we send when you request access.
The brief from Voltas, the Foster + Partners architectural intent, and the constraints of building MEP inside a landmark. Steel-feather geometry, no repeating grid, museum-grade environmental targets, zero tolerance for exposed services in any gallery view.
How HVAC, electrical, plumbing, fire and the specialist museum systems were routed inside the feather towers, every run modelled against the structural steel, every penetration negotiated, every plenum and riser fought for. What was hard, what nearly broke, what got resolved before fabrication.
Contractor-side spool drawings, fabrication-ready isometrics, federated MEP-vs-structure clash reports, riser sets and plant room layouts. The drawings Voltas built from on site.
Quantified outcomes where we have them, clashes resolved before fabrication, rework avoided in the feather towers, programme protected against geometry that allowed no second attempts. Honest numbers.
