Kwaliteitsscore aanbesteding

This tender for the conservation of the Karksi Castle wall section is generally well-structured, with clear technical specifications and a straightforward evaluation criterion. However, it lacks explicit sustainability considerations and relies on a manual submission process for some documents.

Scoreoverzicht

Wettelijke naleving75/100

The tender appears to comply with general legal requirements, including a clear procedure and proper CPV code. Deadlines are reasonable. No disputes are noted. The procedure type (LM) suggests a negotiated procedure, which is permissible.
