Pyramid building as an integrated process

In the first stage of pyramid building the core grows in proportion to the distance from fiducial marks in the court around the pyramid. The upward flow of stones is effectuated by rockers on cribs standing on large step‐structures on the terraces. In the second stage packing‐ and outer casing blocks are mounted sequentially by the same methods along steep gradients on symmetrical faces of the pyramid, starting and ending at opposite corners. Alignment is by sighting from the vertex over the edges and over the corners to the fiducial marks. The two stages, the method of raising the blocks, the geometry of alignment, the special ramps, the proposed sequence of mounting the casing blocks are based on archaeological evidence, and all can be incorporated in a coherent building sequence.
