The Integrated Friction Management Model: A Proposed Construction Sequence for the Great Pyramid of Khufu

Traditional theories of Great Pyramid construction struggle to reconcile two conflicting requirements simultaneously: the logistical throughput needed to place 2.3 million core blocks within a 27-year window (approximately one block every 2.5 minutes), and the megalithic capacity needed to raise approximately 62 granite and limestone blocks weighing between 40 and 80 tonnes each to heights exceeding 43 meters. This paper proposes an integrated construction model — the Integrated Friction Management Model — that addresses both requirements through a unified engineering framework centered on a single geometric insight: the 26-degree incline.The model proposes a 20-meter-wide internal open-air ramp built at a constant 26-degree incline — the same angle used for the pyramid’s internal passages and Grand Gallery. This specific geometry creates a self-locking environment where limestone blocks remain stationary by friction alone between hauling cycles, providing an inherent safety brake. Three primary mechanical systems — the Logistical Ramp, the Grand Gallery counterweight sledge, and a proposed Upper Gallery — work in sequence to solve the construction problem across different phases of the build.A key innovation is the Walking Beam: a leveraged rocking system that allows massive blocks to be incrementally advanced up the slope with crews of fewer than 70 men while maintaining a 2.06:1 safety margin even for 80-tonne granite loads. The model further proposes that the pyramid’s known internal voids — the Grand Gallery, the North Face Corridor, and the recently detected ScanPyramids ‘Big Void’ — functioned not merely as burial or symbolic spaces, but as the mechanical engines that made construction physically possible. The existenceJepsen — Integrated Friction Management Model — p. 3or non-existence of an Upper Gallery in the location predicted by this model is identified as the single most testable prediction of the entire theory.
