In a nutshell
As-built documentation is more than just a revised drawing: its scope, inspection status, and data source must be clearly traceable.
As-built documentation involves comparing existing or newly recorded data with the actual state of the building and presenting it in a structured format. The result can consist of plans, point clouds, models, and supplementary attribute data.
When is this topic relevant?
- Project completion and inventory handover
- Renovation and expansion planning
- Technical documentation of systems
- Database for Facility Management
What results can you expect?
- Verified inventory plans
- Point clouds and photo documentation
- CAD or BIM as-built model
- Change and testing instructions
What are the key factors when commissioning a service?
The term "as-built" does not automatically describe a level of accuracy. Therefore, the scope of data acquisition, tolerances, and the status of the information are agreed upon in advance.
From need to usable data basis
| Step | What will be clarified? |
|---|---|
| Task 1 | Usage, areas, accuracy and result format |
| 2. Recording | Access, security, measurement method and spatial reference |
| 3. Preparation | Registration, testing, evaluation and modeling |
| 4. Handover | Data structure, quality control and instruction |

Frequently asked questions
What information do you need for a quote?
Helpful information includes the location, approximate size, any existing plans or photos, desired outcome, and timeframe. We will clarify any open technical points together.
How is the required accuracy determined?
Accuracy is derived from the intended use. Different requirements apply to an area overview than to plant connections or a detailed BIM model.
Can existing plans be incorporated?
Yes. Existing documents can serve for preparation, orientation, and supplementation. Deviations from the recorded data will be handled transparently.
In what formats is the data transferred?
Depending on the project, we deliver formats including E57, RCP/RCS, LAS/LAZ, DWG, DXF, Revit, IFC, and PDF. The target format is agreed upon before the project begins.
