The Challenge

What the client needed to solve

A residential architect in Indore had completed design development in AutoCAD but needed to submit a full BIM model to the developer's contractor. The contractor's BIM requirement specified a LOD 300 Revit model with coordinated floor plans, elevations, sections and room schedules. The project had a three-week deadline before the contractor's tender close. The architect had no in-house Revit capacity and could not afford to delay or hire a full-time Revit modeller for a single project.

Our Solution

How The Zenith Visions delivered

The Zenith Visions received the complete AutoCAD DWG file set on Day 1. After a 2-hour scope call to confirm LOD requirements, layer conventions and sheet setup preferences, we began modeling immediately. The architecture model was built wall-by-wall, family-by-family from the DWG geometry, with all elements carrying correct material and dimension parameters. Sheets were set up to the client's title block and submitted for review at Day 8, allowing a four-day review window and final delivery at Day 12.

  • Complete LOD 300 Revit model: walls, floors, roofs, doors, windows, stairs, railings
  • Custom families for non-standard door and window types matching the design intent
  • Coordinated floor plans, elevations, sections and 3D views on client title block
  • Room schedule with areas, finishes and door/window counts auto-generated from model
  • Cross-checked against source DWG: all discrepancies flagged in a conversion note
  • Final model delivered in Revit 2024 and DWG export; PDF sheet set issued simultaneously
The Results

Measurable outcomes

12
business days to full LOD 300 delivery
0
plan check corrections from the contractor
100%
of sheets approved without revision
40%
fewer RFIs vs. prior CAD-only submissions
The model came back cleaner than anything our in-house team would have produced in the same time. We have now outsourced three more projects to TZV and will not go back to managing Revit production in-house.
