Core Stone Supply (Giza Plateau)
+1,200 blk/mo
Nummulitic Limestone Stock
14,250 blocks
Coarse local limestone quarried 400m south of the pyramid base. Transported on cedar sledges over wet tafla clay paths.
Fine White Casing (Tura Quarries)
Nile Ferries Active
Tura Casing Blocks at Giza Harbor
1,820 blocks
Fine limestone cut across the Nile at Tura. Inspector Merer's logbook confirms 30-block barge runs directly into Giza canal basin during Akhet flood.
Granite Monoliths (Aswan, 800km South)
Relieving Chambers
50-Ton King's Chamber Beams Ready
9 / 43 delivered
Pounded with spherical dolerite hammerstones. Floated downriver on giant transport barges only during the peak crest of the Inundation.

Copper Chisels in Circulation
4,500 chisels
Unalloyed copper dulls rapidly against limestone. Smithies burn charcoal day and night to reheat, re-hammer, and work-harden chisel bits.

Workforce Morale
High (88%)
Archaeology at the "Lost City of the Pyramids" proves workers were respected, fed prime beef, received medical treatment (set bone fractures), and took immense pride in their gang titles.
Sledge Hauling & Water Lubrication
Friction: μ = 0.16
Pouring water on Nile silt ahead of wooden sledges reduces friction by ~50%, halving the human pull force needed per 2.5-ton block.

Archaeologists genuinely debate how ramps were configured to reach 146 meters. Select the system for your build:
Direct single ramp extending southwest into the desert. Easiest for hauling, but requires astronomical material volume as the pyramid rises.
Hauling Speed: Fast
Material: Colossal
Max Feasible: ~70m
Corner Check: Unobstructed
Ramps switch back and forth across one or two faces of the pyramid. Compact footprint, but covers casing stones and creates dangerous turning platforms.
Hauling Speed: Moderate
Material: Low
Turn Danger: High
Casing Dressed: Delayed
Wraps around all four stepped tiers as the structure rises. High stability, but turning 2.5t blocks around 90-degree corners requires complex wooden rocker pivots.
Hauling Speed: Moderate
Material: Low
Corners Sight: Blocked
Full Height: Yes (to Apex)
Exterior ramp builds the bottom 43m (70% volume), then an internal corkscrewing tunnel behind the casing rises to the apex with open corner turning notches.
Hauling Speed: Steady
Material: Minimal
Complexity: Very High
Casing Precision: Superior
Architectural Note: As height passes Course 60 (~45m), linear ramps become geometrically impossible without consuming more stone than the pyramid itself. You can transition your ramp system at key milestones!

The Lessons of Dahshur & Meidum
Sneferu's architects at Meidum experienced outer casing slippage, and at Dahshur the Bent Pyramid cracked at 54°, forcing a reduction to 43°. Khufu's Vizier Hemiunu has solved this with a solid bedrock core and massive horizontal foundation blocks!
