Definition
As-built documentation is the complete record of a building or structure as it was actually constructed, capturing the final, real state rather than the original design intent. It brings together drawings, models, and data that reflect what truly exists on site.
Because construction rarely matches the initial plans exactly, this documentation is vital for anyone who needs to understand, maintain, or modify a building later. It provides a dependable source of truth about the finished structure.
In simple terms, as-built documentation is the accurate, final record of what was really built.
How It Works
As-built documentation is compiled by recording the finished structure and any changes made during construction. This can include updated drawings, BIM models, photographs, and increasingly reality capture data such as laser scans that measure the building precisely.
Scan-based documentation captures the true dimensions and positions of everything on site, producing a reliable digital record. This information is organised so that owners and teams can reference it confidently for operation, maintenance, and future projects.
Applications
As-built documentation is used in facility management, renovation, handover, and compliance. It supports maintenance, guides refurbishment, informs future construction, and provides owners and regulators with an accurate record. Reality capture makes it more precise and complete.
Benefits
- An accurate record of the finished structure.
- Reliable basis for maintenance and renovation.
- Fewer surprises in future work.
- Highly precise when created from scans.
- Valuable documentation for owners and regulators.

Frequently Asked Questions
What is as-built documentation used for?
It records a structure as actually built and is used for maintenance, renovation, handover, and compliance.
What does as-built documentation include?
It can include updated drawings, BIM models, photographs, and reality capture data such as laser scans.
How is it different from as-built drawings?
As-built drawings are one part of it; as-built documentation is the broader record that can also include models, data, and photos.
How does reality capture improve as-built documentation?
Laser scanning captures the finished structure precisely, producing an accurate and reliable digital record.
