SP 73 and India’s Uniform Digital Building Code
Where India Stands Today
Every state interprets the National Building Code differently — formats, forms, and standards vary.
This fragmentation costs billions in delays and rework.
What SP 73 Can Change
SP 73:2023 introduces India’s first codified BIM linkages — bridging design intent and approval data.
Think of it as the API layer of India’s construction ecosystem.

Why It Matters
Digital compliance is not just efficiency — it’s accountability.
When rules become machine-readable, corruption becomes machine-detectable.
The Bigger Picture
SP 73 is to architecture what GST was to taxation — a unifier for growth and transparency.
It lays the foundation for a National BIM Stack that connects education, policy, and practice.

September 2026 Update
The case for common digital standards now has a further strategic
dimension. Standards are not only about efficiency and compliance. Open,
nationally governable standards can also help ensure that Indian project
information remains portable across technologies rather than becoming
permanently dependent on particular proprietary platforms.
I explore this relationship between standards, interoperability and
digital sovereignty in a new essay: “Digital Sovereignty, BIM and India's
Built Environment.”
