What makes renovation surveying special
In existing buildings the installation situation is often only truly assessable on site. Gaps between plan, specification and real opening are common. Renovation surveying needs a solid mix of measured values, photo evidence and clear notes.
Important points for capture
- • Several width and height dimensions instead of single values
- • Photograph visible existing specifics
- • Describe junction details and adjacent components clearly
- • Mark open points for follow-up, do not omit them
- • Document data fully before preparation starts
Typical risks in renovation
Assumptions from old documents
Existing drawings or old surveys help but do not replace current on-site verification.
Too little documented deviation
If special conditions are not in the dataset, the office is left with room for interpretation.
