The Great Pyramid was built over a period of around 20 years during the reign of Pharaoh Khufu, the second king of the 4th dynasty of ancient Egypt[2].

Mini paragraph: The pyramid was constructed as an elaborate royal tomb for Pharaoh Khufu, likely starting soon after he took the throne around 2589 BC. It took around 20 years to complete this monumental project, which involved quarrying, transporting and precisely placing over 2 million heavy stone blocks.

  • It is estimated that the construction involved a workforce of around 20,000 skilled laborers, as opposed to slaves [3]. The workers were likely paid Egyptian farmers who provided the labor during the flood season when they were not occupied in agricultural activities[4].
  • The pyramid was constructed using around 2.3 million limestone and granite blocks, with an average weight of 2.5 tons per block[5].
  • The blocks were cut from nearby quarries using copper chisels and stone hammers[6]. They were transported via sleds and wooden tracks along the Nile River and moved into place using ramps, levers, and a pulley system[7].
  • The purpose of the pyramid was to serve as an elaborate tomb for Pharaoh Khufu, as Egyptian kings of the era sought to be buried alongside all necessities for a comfortable afterlife[3].
  • The internal structure consists of three chambers – the King’s Chamber, the Queen’s Chamber, and an unfinished underground chamber. Intricate passageways and galleries connect the chambers[2].
  • Originally rising to a height of 481 feet, the pyramid was topped with smooth white limestone casing stones covering the stepped core structure below. Most of the outer casing is now gone[2].

Additional Details on Construction:

  • The pyramid covers an area of over 13 acres and originally stood at a height of 146 meters. This mammoth scale and size required meticulous planning, oversight, and coordination over the 20-year construction period.
  • It is estimated that 5.5 million tonnes of limestone, 8,000 tonnes of granite, and 500,000 tonnes of mortar were used in its construction. This material had to be quarried, transported, and precisely installed.
  • The outer casing stones were highly polished limestone transported from Tura, near modern Cairo. This conferred a smooth, gleaming finish visible from miles away.
  • Inside the pyramid, the King’s Chamber is built entirely from granite brought from Aswan, over 500 miles away. The granite blocks used weigh up to 80 tonnes each.
  • The change in internal structure from horizontal to sloping layers indicates the builders adapted techniques as they gained experience.

Mini paragraph: The pyramid’s sheer monumental scale is evident from the vast amounts of materials used – over 5 million tons of stone and half a million tons of mortar. Dense granite for the internal chambers was transported from hundreds of miles away. The evolution in architectural design and adaptation of techniques over the long construction period also stand testament to the skills and ingenuity of the builders.

In recent decades, various theories have been proposed regarding the construction techniques:

Mini paragraph: In the absence of definitive historical records, many modern Egyptologists, architects, and engineers have proposed theoretical techniques for how the pyramid could have been constructed using the limited tools available to ancient Egyptians. Experimental archeology has tested ideas like levering and ramps to build small-scale replicas.

  • Levering methods – Small and large levers could have been used in conjunction with ramps to incrementally lift blocks. Experimental constructions have demonstrated such techniques[6].
  • Internal ramps – French architect Jean-Pierre Houdin has hypothesized the use of an internal spiral ramp to lift blocks inside the pyramid. Some evidence of internal ramps has been found[6].
  • Building experiments – In the 1990s, teams led by Mark Lehner and Nova demonstrated pyramid construction at a small scale using ancient tools and techniques like sleds, tracks, levers, and ramps[6].
  • Water shafts – The existence of water shafts and paleo-harbors near the pyramids suggests waterways were used to transport blocks from nearby quarries[9].
  • In 2018, archaeologists discovered remnants of ancient sleds and tracks at a quarry, giving insights into how the massive blocks were transported[10].

Additional Details on Modern Research:

  • In the 1980s, French materials engineer Joseph Davidovits proposed that the blocks be cast on-site using limestone concrete molded in wooden forms. This theory remains disputed.
  • Cosmic ray muon radiography shows evidence of previously unknown voids and gaps inside the structure that warrant further scanning and exploration.
  • Geological analysis of stone samples indicates many blocks were quarried locally from the Giza plateau and its vicinity rather than further afield.
  • Ongoing 3D laser scans and computer modeling continue to reveal new micro-details about tool marks, block placements, and construction sequences.

The Great Pyramid Workforce Operations

The construction of the Great Pyramid of Giza was a massive undertaking that required a large and well-organized workforce. The exact number of workers is unknown, but estimates range from 20,000 to 100,000 people[11].

The workforce was likely composed of farmers, laborers, and skilled craftsmen. They were organized into teams that were responsible for different tasks, such as quarrying, transporting, and lifting the stones.

The workforce was probably divided into two main groups:

  • The quarrying team was responsible for extracting the limestone blocks from the nearby quarries.
  • The transportation team was responsible for transporting the blocks to the pyramid site.

The transportation team used a variety of methods to move the blocks, including rollers, levers, and inclined planes. The blocks were likely moved on sleds or boats during the flood season when the Nile River was high.

The lifting team was responsible for raising the blocks into place. They used a variety of techniques, including ramps, levers, and pulleys.

The construction of the Great Pyramid was a complex and challenging undertaking. It required a great deal of planning and organization.
