This article presents a methodological and scientific research. It is technical in its application and operative in the determination of the tools and their usage. It follows up on the "mechanical" theories and it is devoted to develop a "constructive system" as a whole - which is innovative among the archaeological researches "in situ".

The research is based on taught knowledge and practical skills in reference to the "original, interactive and predicative" model and, on the verification, through archaeological observations, of the construction work and its surroundings, "in situ." The reasoning will be lead by a concern in logic and coherence.

The research rests on three fundamental postulates:
  1 - materials constituting the body of the pyramids are taken on the spot, on the plateau of Giza according to the principle of "exploiting all around to abound in the centre", monoliths made of granite are coming from Aswan, located 850 km up on the Nile valley.
   2 - the building principle is necessarily simple, efficient, repetitive and effort saving. It is based on the principle of "always erect on what has just been erected."
  3  - the set of tools must be of a simple usage and easy to make, according to the technological context of the era.  

   
 The three great sleek pyramids of the Giza plateau are located at the centre of the quarries the material the pyramids were built with comes from
