What is the recommended minimum time an architect should retain project files?

Retaining project files until after the limitation period for pursuing a claim for professional negligence is crucial for architects. This period varies by jurisdiction but typically allows clients to file a claim against the architect for a set number of years after the completion of the project. By retaining files for at least this duration, architects ensure they have access to important documentation that could serve as evidence in case of disputes or claims.

Furthermore, these files can provide valuable information regarding design decisions, contract details, and communications that are essential in defending against any accusations of negligence. This practice protects both the architect's professional integrity and financial liability, as it aligns with legal responsibilities and best practices in the industry.

In contrast, shorter retention periods like one or five years do not adequately account for the typical limitation periods, which often extend beyond those time frames. While retaining files for ten years might seem prudent, it may not be necessary in every case, particularly if the limitation period is shorter, thus not aligning perfectly with the minimum recommendations for retaining pertinent documentation.
