This paper presents a metric analysis and interpretation of the 3D survey of the Late Roman Fort of Umm al-Dabadib (Kharga Oasis, Egypt). The aim is to verify if a modular measure was used in the construction of the Fort and whether this was congruent with Roman or Egyptian units of measurement. Horizontal and vertical sections were extracted from the 3D model of the Fort derived from a close-range photogrammetry survey method. The resulting technical drawings were used for the study and interpretation of the dimensional patterns of the Fort that revealed the correspondence<strong> </strong>of the units of measurement of the building to Egyptian Reformed Cubit. This research is part of the project LIFE (Living in a Fringe Environment), funded by the ERC CoGrant 68167.
