An honest, source-cited summary of where BIM stands in India. We list only what is verifiable from primary sources (BIS catalog, ISO catalog, government / agency websites). Common third-party claims about CPWD/NHAI mandates that we could NOT verify are explicitly flagged so you don't repeat them.
Indian Standards on BIM
| Fact | Status | Source | Note |
|---|
| Has BIS published a dedicated IS standard on BIM? | NO | BIS e-Sale catalog — search 'building information modelling' returns zero results | As of early 2026 |
| Does IS 17765 cover BIM? | NO — common confusion | BIS catalog: IS 17765:2022 is 'Health informatics — Personal health data generated on a daily basis' (committee MHD 17, Medical Informatics) | DO NOT cite IS 17765 as a BIM standard — it isn't one |
| Is there an IS/ISO equivalent of ISO 19650 in India? | Not found in BIS catalog | BIS e-Sale catalog search | Indian projects reference ISO 19650 directly until BIS publishes an Indian Adoption |
| Is there a BIS sectional committee for BIM? | Not publicly documented | BIS CED committee index | Civil Engineering Department (CED) committees cover NBC and related; no published BIM-specific committee identified |
Indian Government BIM Mandates
We searched cpwd.gov.in, nhai.gov.in, mmrda.maharashtra.gov.in, dda.gov.in, dmrc.org and others. The findings:
| Fact | Status | Source | Note |
|---|
| CPWD BIM mandate | UNVERIFIED | No primary CPWD circular located | Third-party blogs cite a '₹20 crore threshold from 2024' but no official CPWD circular has been retrieved. Treat as rumour until you can pull the source PDF. |
| NHAI BIM requirement | UNVERIFIED | No primary NHAI policy circular located | Bharatmala / expressway BIM claims circulate; no published NHAI policy circular has been verified |
| MMRDA / Mumbai Metro BIM mandate | UNVERIFIED | — | — |
| DDA / DMRC / DFCCIL / AAI / IRCON mandates | UNVERIFIED | — | — |
| NITI Aayog / MoHUA national BIM policy | UNVERIFIED | — | No national-level policy document located |
Verified Indian BIM Adoption Examples
| Fact | Status | Source | Note |
|---|
| NCRTC — Delhi-Meerut RRTS (Namo Bharat) | VERIFIED | ncrtc.in/building-information-modelling/ | NCRTC publicly states all Namo Bharat stations are designed and developed on a BIM platform. Has set up the 'APARIMIT' BIM lab at Duhai Depot. This is a voluntary disclosure of adoption — NOT a mandate. |
| India BIM Association (IBIMA) | VERIFIED | ibima.co.in | Registered as a not-for-profit society on 2 April 2019 in Bangalore (Reg. DRB4/SOR/5/2019-2020). Focuses on BIM education, summits, policy advocacy. |
| RICS South Asia | VERIFIED organisation | RICS India website | Runs BIM training and the RICS-India Construction Conference (recent edition 13 July 2024, Mumbai). 'BIM SIG' label specifically — UNVERIFIED. |
Software Stack Used in India
These are commonly marketed and used — exact market shares are unverified.
| Fact | Status | Source | Note |
|---|
| Authoring — buildings | Common | Vendor websites | Autodesk Revit (most common), Graphisoft ArchiCAD, Nemetschek Allplan |
| Authoring — structural steel | Common | Vendor websites | Trimble Tekla Structures (dominant for steel detailing) |
| Authoring — infrastructure | Common | Vendor websites | Bentley OpenBuildings, OpenRoads, OpenRail, OpenBridge |
| Coordination | Common | — | Navisworks, Solibri, Revizto, BIMcollab |
| CDE — most common | Common | — | Autodesk Construction Cloud (BIM 360), Aconex (Oracle), Bentley ProjectWise, Asite |
Frameworks Indian Engineers Encounter
| Fact | Status | Source | Note |
|---|
| ISO 19650 series (Parts 1-5) | VERIFIED international standards | iso.org catalog | Concepts (Pt 1), Delivery (Pt 2), Operations (Pt 3), Information Exchange (Pt 4), Security (Pt 5). Indian projects cite directly. |
| ISO 16739-1:2024 (IFC) | VERIFIED — current schema is IFC 4.3 ADD2 | iso.org/standard/84123.html | Use for any project with infrastructure (rail, road, bridge, tunnel) |
| AIA LOD numbering 100-500 | Most-cited globally and in India | AIA G202-2013 | — |
| BIMForum LOD Specification | Free annual reference | bimforum.org/lod | Most-cited practical reference for object-by-object LOD definition |
| BS EN ISO 7817-1:2024 LOIN | Replaces BS EN 17412-1:2020 | iso.org/standard/82914.html | Modern alternative to AIA LOD; adoption is slow |
| Uniclass 2015 (UK) | Most-used classification on Indian projects | uniclass.thenbs.com | Free, frequently updated, no Indian alternative |
Notes
• Bottom line: India has NO published IS standard on BIM and NO verified national mandate as of 2026
• Indian BIM projects reference ISO 19650, IFC (ISO 16739), Uniclass, and BIMForum LOD directly — there is no Indian-specific framework
• If you see a third-party claim about a CPWD or NHAI BIM mandate, ask for the source circular before believing it
• NCRTC RRTS (Namo Bharat) is the most prominent verified India BIM adoption story — they publicly disclose voluntary BIM use
• IBIMA (India BIM Association) is the registered industry body — see ibima.co.in
• Opportunity: BIS has not published a BIM standard. Indian engineers contributing to CED committees can shape this
• If you discover a primary-source CPWD/NHAI/etc. BIM circular, share it — we'll update this snapshot
