What is Architectural BIM Modeling?
Building Information Modeling is more than 3D visualization. It is a data-rich, intelligent process that brings together geometry, materials, system information, cost data, and construction sequencing into a single, coordinated model.
For architectural firms, BIM replaces disconnected 2D drafting with a live, collaborative model that all project stakeholders can work from simultaneously. Design errors that would surface on site are caught in the model. Coordination between architecture, structure, and MEP disciplines happens before a single brick is laid.
At CAD Drafting Services, we have been working in this space since the early adoption days of BIM in the AEC industry. We understand the technology deeply, and more importantly, we understand the real project pressures that come with it.
BIM Advantages:
- ✓Fewer RFIs and design clashes during construction
- ✓Faster production of coordinated drawing sets
- ✓Accurate quantity takeoffs directly from the model
- ✓Better client communication through 3D visual documentation
- ✓Compliance with BIM mandates in the US, UK, and Australian markets
Our Architectural BIM Services
PDF to BIM Conversion Services
We convert 2D PDF drawings, scanned documents, and legacy plan sets into fully intelligent Revit BIM models. Whether you have hand-drawn sketches, flat PDF files, or low-resolution scans, our team extracts all relevant design information and rebuilds it as a parametric, editable BIM model ready for coordination, documentation, or handover.
This service is particularly valuable for renovation and retrofit projects where existing documentation only exists in PDF or printed format and needs to be brought into a modern BIM workflow.
What we deliver:
- Revit models built from PDF floor plans, elevations, and sections
- LOD 200 to LOD 400 depending on project requirement
- Full architectural elements including walls, doors, windows, roofs, stairs, and finishes
- Ready for further design development or clash detection
We have completed PDF to BIM conversion projects for: residential complexes, commercial offices, healthcare facilities, educational institutions, and mixed-use developments across the US, UK, and Australia.
Why AEC Firms Choose CAD Drafting Services
Over two decades of precision delivery, standard-compliant processes, and global scale.
21 Years in the Industry
We were founded in 2005, which means we were building BIM models before most firms had even adopted the technology. That depth of experience shows in how we handle complex projects, tight deadlines, and demanding client requirements.
Dedicated BIM Team
Our team includes certified Revit modelers, BIM coordinators, architects, and project managers who have worked on hundreds of projects across the US, UK, Canada, and Australia.
Your Standards, Not Ours
We follow your BIM Execution Plan, your office standards, and your file naming conventions. Every deliverable is formatted for your workflow, not ours.
LOD 100 to LOD 500
We cover the full spectrum of model development. Whether you need a concept massing model or a fully detailed as-built record model, we have the expertise to deliver it.
Built-In Quality Control
Every model goes through a structured QC process before delivery. Clash detection, model audit reports, and drawing coordination checks are standard on every project.
Flexible Engagement
Work with us on a per-project basis or as an extended team integrated into your studio. We adapt to how you work.

BIM Level of Development (LOD) We Deliver
We develop models to precise LOD specifications from early conceptual drafts to coordinated, fabrication-ready, and field-verified record packages.
LOD 100 BIM
Conceptual or massing model intended for complete house study, layout, and orientation.
LOD 200 BIM
Common systems design development with approximate volume, shape, location, and orientation.
LOD 300 BIM
Pre-construction modeling representing the end of the design phase with precise geometry, orientation, and location.
LOD 400 BIM
An accurate model of construction requirements and specific products, ready for fabrication shops and installation crews.
LOD 500 BIM
The 'as-built' model element accurately represents field-verified models matching exact built locations, dimensions, and operational parameters.
Markets We Serve
We calibrate all architectural BIM modeling outputs, notation tags, line weights, templates, and scales to local building requirements.
US building codes and AIA standards compliance. Models and layouts are customized to US permit and zoning rules.
- AIA Layering Standards
- CSI MasterFormat Classifications
- NCS Standards Compliance
Frequently Asked Questions
We accept DWG, DXF, DGN, PDF, RVT, IFC, and scanned image files. If you have drawings in another format, contact us and we will advise on the best approach.
We work in Revit 2020 through the latest release. We match the version you are working in so files are directly compatible with your team.
Yes. We review your BEP at project start and model accordingly. If you do not have a BEP, we can recommend a standard approach based on your project type and market.
Yes. We are experienced with BS EN ISO 19650 requirements and have delivered projects requiring compliance with UK BIM mandates, including Common Data Environment protocols and information delivery milestones.
Turnaround depends on project size and complexity. Small projects are typically delivered within 3 to 5 working days. Larger projects are scoped with a phased delivery schedule agreed upfront.
Yes. Many clients engage us on a retainer basis for ongoing model management, drawing updates, and design coordination support throughout the project lifecycle.
