The pyramid of Userkaf, the first king of the 5th Dynasty of Ancient Egypt (ca. 2494-2487 BC) is one of the World Heritage monuments located on Saqqara plateau Necropolis in Egypt. Like most of the Ancient Egypt’s monuments, this pyramid is almost in ruins and its preservation is a challenge for modern conservators and engineers. Currently, the pyramid is in a very bad condition and most of the main building elements can be recognized only thanks to the previous archaeological studies carried out on site. The structure of the pyramid is also severely affected by earthquakes. The elaborated 3D model of the pyramid allows us to make conclusions regarding the building process of the pyramid, to evaluate the stability and current state of preservation of the pyramid’s stone material and mortar, as well as to reconstruct initial shape and dimensions of the monument.
