Accurate Revit BIM Model from DWG + Structural IFC

I have a detailed architectural DWG of an existing building and an accompanying IFC structural model that defines the structural geometry, levels, grids and main structural elements.
I need a clean, accurate and fully editable BIM model created in Autodesk Revit.
Scope of work
- Model all architectural elements shown in the DWG, including walls, floors/slabs, roofs, doors, windows, stairs and openings.
- Reproduce the DWG geometry as accurately as possible.
- Use the supplied structural IFC as a coordination reference for levels, elevations, grids, columns, beams, slabs and structural positions.
- Maintain correct alignment and dimensions between the architectural model and the structural IFC.
- MEP systems are NOT required.
- Furniture, rendering, entourage and decorative modelling are NOT required.
Important
This is NOT an automatic DWG-to-BIM conversion. The Revit model must be properly created using native, editable BIM elements.
Geometric accuracy and coordination with the supplied DWG and IFC are the main priorities.
Required deliverables
- Native Autodesk Revit file (.RVT)
- IFC export of the completed model
- Properly organised levels and views
- Fully editable BIM elements
The final model will be checked by overlaying/coordinates comparison against the original DWG and the supplied structural IFC.
Please state in your proposal:
1. Which Autodesk Revit version you use.
2. Your fixed price for the complete work.
3. Estimated delivery time.
4. Examples of similar DWG-to-Revit/BIM projects.
5. Your experience working with IFC structural models.
Please do not bid if you intend to provide only an automatic conversion or a non-editable 3D model.
