Heritage BIM (HBIM) for Pune''s Conservation Projects 2026

Pune is the second-densest concentration of ASI-listed, MTDC-listed and PMC-graded heritage monuments in Maharashtra after Mumbai — and 2024-2028 is the first time in the city''s history that the conservation budget has been backed by structured digital-twin scope. The combined declared spend across ASI Mumbai Circle, Maharashtra State Directorate of Archaeology and Museums, Maharashtra Tourism Development Corporation (MTDC), PMC Heritage Cell, INTACH Pune Chapter, Indian National Trust for Art and Cultural Heritage, JSW Foundation, Tata Trusts and the Smart City Mission''s heritage component now crosses ₹400 crore by 2028 — covering Aga Khan Palace, Shaniwar Wada, Pataleshwar Cave Temple, Sinhagad Fort, Vishrambaug Wada, Lal Mahal (reconstruction documentation), Saras Baug Ganesh Temple, Parvati Hill Temple Complex, Tulshibaug Temple, Omkareshwar Temple, Bhuleshwar Temple (Yawat), Purandar Fort, Rajgad Fort, Torna Fort, Kasba Ganpati Mandir, Mahatma Phule Wada, Tilak Wada, Khasgi Wada, Patwardhan Museum, Raja Dinkar Kelkar Museum building, the Pune Cantonment heritage precinct, the NDA Khadakwasla heritage buildings and the Pune University Main Building (Governor''s Bungalow).

Every one of these tenders since 2024 includes — buried inside the technical scope — a mandatory Scan-to-HBIM (Heritage Building Information Modelling) deliverable. The Pune talent pool with hands-on HBIM experience is genuinely under 70 engineers in the entire city. The salary follows the scarcity: ₹6–13 LPA, with strong project-bonus structures from JSW Foundation and Tata Trusts conservation budgets.

Why HBIM Is a Distinct Discipline from Regular BIM

Heritage BIM is not Revit-with-a-tile-texture-applied. It is a fundamentally different way of modelling because the geometry is captured, not designed. The walls are not vertical. The columns are not identical. The slabs sag. The arches are hand-cut and asymmetrical. Mouldings repeat in 17th-century Maratha, 18th-century Peshwa, 19th-century Anglo-Indian and 20th-century Art Deco vocabularies on the same Pune street. The 2026 ASI / MTDC / PMC technical scope expects an engineer fluent in this stack:

• Leica RTC360 / FARO Focus Premium / NavVis VLX / Matterport Pro3 / Trimble X12 — terrestrial laser scanning for point-cloud capture.
• Phase One iXM / DJI Mavic 3 Enterprise / DJI Matrice 350 RTK — photogrammetry and drone capture for facades, roofs and inaccessible fort walls.
• Autodesk ReCap Pro / Leica Cyclone / Bentley Pointools — point-cloud registration, unification, decimation and segmentation.
• Autodesk Revit + Allplan + ArchiCAD — for the HBIM model itself; Allplan and ArchiCAD are often preferred over Revit for very irregular heritage geometry because of their freer mesh-to-element workflows.
• Rhino + Grasshopper + RhinoVAULT + Kangaroo + Karamba3D — for parametric heritage-element libraries (Maratha bracket, Peshwa column capital, Anglo-Indian moulding, Mughal arch profile).
• Dynamo + Python — for automating element-naming, deterioration-mapping and ASI-format export.
• Autodesk Navisworks + Solibri + Revizto — for federation between point-cloud, HBIM model and intervention proposal.
• CloudCompare + Open3D — open-source point-cloud analysis for deformation, settlement, crack and moisture mapping over time.
• ASI Heritage Information Format + INTACH grade-level documentation format — the ASI / MTDC / PMC submission templates.

The 9 HBIM Deliverables Pune Conservation Tenders Demand

1. Registered, unified, decimated point cloud — typically 8–18 billion points unified down to a 60-million-point working set, georeferenced to the ASI / Survey of India coordinate system.
2. Photogrammetric mesh of facades, roofs and inaccessible elements — drone-photogrammetry textured mesh, decimated for HBIM integration.
3. HBIM Architectural Model — walls, columns, slabs, arches, mouldings, brackets, capitals modelled to LOD 300/400 with parametric heritage-element families.
4. HBIM Structural Model — load-bearing walls, RCC interventions from previous restorations, timber-truss roof, masonry-arch geometry.
5. Deterioration Mapping Overlay — moisture, salt-efflorescence, biological growth, crack mapping, settlement mapping, vegetation intrusion, mapped as Revit annotation families overlaid on the HBIM model.
6. Material Library — sandstone, basalt, laterite, lime plaster, lime mortar, jaggery-lime mortar, surkhi, teak, deodar, with chemical-analysis tags from the conservation laboratory.
7. Intervention Proposal Model — proposed repointing, stitching, grouting, replacement, reconstruction; with retain-replace-reconstruct (RRR) tags per element.
8. Federated Navisworks / Solibri Coordination Model — point cloud + HBIM + intervention proposal; deviation analysis between point cloud and HBIM.
9. ASI / MTDC / PMC Format Export — the official heritage-documentation export with metadata fields per ASI / MTDC / PMC schema.

• Month 2: Leica RTC360 / FARO Focus / NavVis VLX site operation + Autodesk ReCap Pro point-cloud registration + Leica Cyclone (60 hours).
• Month 3: Scan-to-HBIM modelling — point-cloud to Revit / Allplan / ArchiCAD wall, column, slab, arch and moulding modelling at LOD 300/400 (80 hours).
• Month 4: Parametric heritage-element library in Rhino + Grasshopper — Maratha bracket, Peshwa capital, Anglo-Indian moulding, Mughal arch (60 hours).

Full deliverable: registered point cloud, HBIM model, deterioration overlay, RRR intervention proposal, ASI / PMC format export. This is the deliverable that converts a Pune interview into a ₹6–9 LPA first heritage-BIM offer.

The Three Mistakes Pune Engineers Make That Cost Them the HBIM Offer

1. Modelling a heritage building like a new building. Forcing straight walls, identical columns and uniform slabs onto a 250-year-old wada destroys the entire purpose of HBIM. The deviation between point cloud and model is the deliverable, not the bug. Engineers who present a "cleaned-up" Revit of a heritage building are filtered out at first review by ASI and PMC Heritage Cell.
2. Skipping deterioration mapping. The ASI / MTDC / PMC scope is fundamentally about condition, not aesthetics. Moisture, salt-efflorescence, biological growth, crack, settlement and vegetation-intrusion mapping must be Revit annotation families overlaid on the HBIM model. No deterioration map, no submission.
3. Ignoring RRR tagging. Every element must carry a retain-replace-reconstruct tag with justification. Conservation panels read this first. Engineers who skip RRR tagging or apply it inconsistently are politely shown the door.
