Many alternative, often contradictory, theories have been proposed regarding the pyramid's construction techniques.<ref>{{cite web|date=3 February 2006|title=Building the Great Pyramid|url=https://www.bbc.co.uk/history/ancient/egyptians/great_pyramid_01.shtml|url-status=live|archive-url=https://web.archive.org/web/20090205042037/http://www.bbc.co.uk/history/ancient/egyptians/great_pyramid_01.shtml|archive-date=5 February 2009|access-date=5 April 2009|publisher=BBC}}</ref> One mystery of the pyramid's construction is its planning. [[John Romer (Egyptologist)|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".{{sfn|Romer|2007|pp=327, 329–337}}

The basalt blocks of the pyramid temple show "clear evidence" of having been cut with some kind of saw with an estimated cutting blade of {{convert|15|ft|m}} in length. Romer suggests that this "super saw" may have had copper teeth and weighed up to {{convert|140|kg|lb}}. He theorizes that such a saw could have been attached to a wooden [[trestle support]] and possibly used in conjunction with vegetable oil, cutting sand, [[Emery (rock)|emery]] or pounded quartz to cut the blocks, which would have required the labour of at least a dozen men to operate it.{{sfn|Romer|2007|pp=164, 165}}
