Excuse me sir, but what are you referring to?

Assuming you were speaking of the labor..
Many alternative, often contradictory, theories have been proposed regarding the Pyramid's construction techniques.[23] Not all even agree that the blocks were quarried; Davidovits claims that they were cast in situ using a "limestone concrete", a theory which is rejected by other Egyptologists. The rest accept that it was built by moving huge stones from a quarry, being only unable to agree whether they were dragged, lifted or even rolled into place. The Greeks believed that slave labour was used,
but modern Egyptologists accept that it was built by many tens of thousands of skilled workers. They camped near the pyramids and worked for a salary or as a form of paying taxes until the construction was completed.[citation needed] Their cemeteries were discovered in 1990 by archaeologists Zahi Hawass and Mark Lehner. Verner posited that the labor was organized into a hierarchy, consisting of two gangs of 100,000 men, divided into five zaa or phyle of 20,000 men each, which may have been further divided according to the skills of the workers.[24]
One mystery of the pyramid's construction is its planning. John Romer suggests that they used the same method that had been used for earlier and later constructions, laying out parts of the plan on the ground at a 1 to 1 scale. He writes that "such a working diagram would also serve to generate the architecture of the pyramid with precision unmatched by any other means." He devotes a chapter of his book to the physical evidence that there was such a plan.[25] The 1925 Cole survey discovered as part of some planning an actual Original Builder's Mark, engraved into the pavement perpendicular to the N face.
