Transform your AutoCAD DWG files, PDFs, and paper drawings into intelligent Revit BIM models with BOQ and cost estimate included. Architectural, structural, and MEP. All 50 US states. Fixed price. 2–5 business days.
The AEC industry is mid-transition from CAD to BIM and it is not complete. Millions of buildings were designed in AutoCAD over the past three decades. Renovation projects, tenant improvements, facility upgrades, and asset management projects all require accurate digital records of existing buildings but for most of these buildings, the only records available are legacy AutoCAD drawings or paper blueprints. CAD to BIM conversion bridges this gap turning flat legacy drawings into intelligent BIM models that support modern construction workflows.
There are also current-design drivers. Owners increasingly require BIM deliverables lenders, government agencies, and corporate clients mandate BIM models for projects above certain thresholds. Architects and engineers who still design primarily in AutoCAD face BIM mandates they cannot meet without conversion services. CES provides CAD to BIM conversion as a direct production service you send your CAD files, we deliver Revit models at a fixed price, within a defined timeline, with BOQ and cost estimate included in every conversion.
CES accepts all drawing formats for CAD to BIM conversion. If you have a drawing in any format, we can convert it to a parametric Revit model at your specified LOD level.
LOD Level of Development defines how much detail and data is in your converted BIM model. CES delivers CAD to BIM conversions at any LOD. The right LOD depends on your project phase and what you need the model to do.
| LOD | Detail Level | What CES Delivers | Timeline | Best For |
|---|---|---|---|---|
| LOD 200 | Approximate geometry size and location | Schematic Revit model · Concept cost estimate CES | 1–2 days | Feasibility · Early budget · SD |
| LOD 300 | Accurate geometry + material specification | Full Revit model · BOQ · Cost estimate CES · Most Common | 3–5 days | Design development · Owner BIM mandate |
| LOD 350 | Interfaces and connections defined | Coordination model · GC bid BOQ CES | 4–7 days | Clash detection · GC bidding · CDs |
| LOD 400 | Fabrication detail shop drawing ready | Fabrication model · Shop drawings CES | 7–12 days | Prefab · Steel detailing · MEP coordination |
| LOD 500 | As-built field-verified conditions | As-built BIM record · Facility management CES | Custom | Existing buildings · Renovation · FM |
We design in AutoCAD but our developer client required a Revit LOD 300 model for their construction loan. Converting 180 units ourselves would take 3 weeks. CES did it in 5 days with a complete BOQ and RSMeans cost estimate from the model. Developer got the lender deliverable. We kept our AutoCAD workflow. Perfect solution.
We had 1980s AutoCAD drawings of an office building we were renovating. Our team needed an accurate existing conditions BIM model to design against. CES converted all 3 disciplines to Revit LOD 300 from our DWG files and supplemented with site photos where drawings were unclear. The existing model saved us 6 weeks of field measurement work.
We had PDF permit drawings from a healthcare project that needed MEP BIM coordination. CES converted MEP PDF drawings to Revit LOD 350 with full MEP system families. Ran clash detection in Navisworks. Found 34 major clashes between ductwork and structure that would have been field conflicts. CES paid for itself on the first clash alone.
Submit your AutoCAD DWG files, PDFs, or paper drawings and receive a complete parametric Revit BIM model with BOQ and cost estimate in 2 to 5 business days. All disciplines. Any LOD. Fixed price. NDA protected.
