As-Built CAD Models – Accurate, Intelligent & Project-Ready
When it comes to upgrades, maintenance, or digital transformation, having accurate as-built data is critical. At Offset Services, we specialise in creating high-quality 3D CAD models from real-world site data – giving you a reliable digital foundation for your next project.
What Is an As-Built Model?
An as-built model is a digital representation of a site or structure as it exists today – not just how it was originally designed. We build these detailed models from a range of sources including:
- Laser scan data
- Photogrammetry surveys
- 2D drawings
- Line lists
- And more
No matter the size or complexity of the installation, we’ve got the tools and experience to deliver accurate, complete models you can trust.
Seamless Integration with Your Tools
Our as-built models are fully compatible with all leading CAD platforms, including:
- Autodesk
- AVEVA
- Bentley
- Dassault Systèmes
- Hexagon
So, you can drop our models straight into your workflow without any headaches.
Built on Experience
With over 30 years of industry experience, we’ve delivered as-built 3D models for:
- Redesigns and revamps with little to no existing documentation
- Digital transformation and digital twin projects
- Corrosion remediation planning
- Data management and clean-up
Our models are detailed, intelligent, and tailored to meet the exact needs of your project – on time and to spec.
Why Clients Choose Offset
We add value to your project with:
- General accuracy to ±5mm
- Intelligent modelling to streamline retrofits and redesigns
- Model output for isometric and 2D drawing generation
- Material take-offs and detailed asset data
- Reliable surveys that reduce guesswork and delays
See the Results for Yourself
We’ve delivered accurate, project-critical as-built models across industries – from oil and gas plants to process facilities and infrastructure. Our case studies speak for themselves.

Accurate as-built models play a vital role in the planning and execution of shutdown, maintenance and modification projects. By combining laser scanning with intelligent modelling, engineering teams can verify existing conditions, identify potential clashes and develop designs with greater confidence before work begins on site.
