This volume presents an in‑depth investigation of architectural and environmental surveying methods under conditions of urgency, especially as applied to the built heritage. It explores operative frameworks for rapid measurement, documentation and interpretation of architectural assets in risk or emergency contexts, focusing on methodological protocols, graphic representation and field deployment. The work is structured around case studies authored by Maestri, Mazzetti and Canciani, investigating how drawing, measurement and analysis merge under time‑sensitive conditions. It contributes to the discourse of heritage documentation, offering a systematic approach to surveying in emergency situations.
