Constraint-First Sequencing in Large Stone Structures: A Structural Analysis Inspired by Old Kingdom Pyramids

This paper presents a structural admissibility analysis of large-scale stone construction, using the Great Pyramid of Khufu as an illustrative case. Rather than proposing a historical construction method, the analysis examines which construction sequences are mechanically coherent given known material behavior, load paths, internal void geometry, and observed surface tolerances. The study evaluates whether a constraint-first construction sequence—establishing internal load-defining geometry under support prior to full load engagement—resolves well-documented challenges including void stability, alignment preservation, and casing precision. Internal corridors, chambers, and shafts are interpreted as phased construction features whose geometry and surface condition reflect temporary operational use followed by progressive narrowing or closure. By eliminating structurally inadmissible sequences, the paper demonstrates that a class of internally supported, phased construction pathways exists that satisfies the observed architecture without invoking external ramps, advanced machinery, or unverified assumptions. The analysis is limited explicitly to structural dependency, geometric constraint, and load sequencing, and does not claim historical exclusivity.
