La construction des pyramides égyptiennes selon Leslie Grinsell - 5e partie : méthodes de construction, chronologie

Methods of Construction.

As outlined for pyramids in the preceding pages, apply in principle also to the building of the temples, causeways, temenos walls, and other structures forming the pyramid complex, except insofar as the different types of structure required different individual treatment. 
The special problems involved in the building of the pyramid temples are outside the scope of this work, and the reader is therefore referred to the works of Choisy, Reisner, and Clarke and Engelbach (...). 

Sequence of Building

Evidence of the order in which the various parts of the pyramid complex were built is derived from unfinished pyramid complexes, and from dated inscriptions on some of the stones used. It was broadly as follows :
(1) The substructure of the pyramid was hewn out of the rock (example : Zâwyet el Aryân, North, where the building of the pyramid advanced little beyond this stage). 
(2) The sarcophagus was placed in the tomb chamber before the rest of the pyramid was built (example : Zâwyet el Aryân north pyramid). In at least one instance (Neit) the sarcophagus was placed in the tomb chamber in a rough-hewn condition.
(3) The sarcophagus chamber and other parts of the interior were walled, paved, and roofed (probably in that order). 
(4) The causeway was then, or perhaps earlier, built for transporting limestone and other materials. 
(5 ) The pyramid superstructure was added. 
(6) The casing blocks were dressed after being placed in position. 
(7) The upper temple was built after the pyramid was nearly completed, as shown by dated stone blocks from the pyramid complexes of Khendjer and Ammenemes.
(8) After the causeway had ceased to be used for transport of stone for the pyramid, temenos wall, and upper temple, it was paved, walled, and roofed. 
(9) The lower temple was probably built last of all. 
Although the main building sequence was most likely as outlined above, it should be noted that at the time of the death of Mycerinus his pyramid, upper temple, and lower temple were all well advanced although none had been actually completed. The lengthy process of dressing the pyramid casing must have proceeded while the other parts of the pyramid complex were being built. 

The Time Taken to construct the Pyramid Complex

It was said by Herodotus that it took ten years to build the causeway and twenty years to construct the pyramid of Kheops. As there are about 2,300,000 blocks in this pyramid, a building period of 20 years would have implied the quarrying, transport, and laying of over 300 blocks a day throughout each year. Available evidence suggests that the larger pyramids of the Old Kingdom may have taken between 20 and 30 years to build, although about 4 years would have been enough for some of the smaller pyramids of the Middle Kingdom, which were not well built.

Maintenance.

The drain on the country’s resources did not end when the pyramid complex was completed ; for a large staff of priests, overseers, and other officials were maintained, not only during the king’s lifetime but also for some centuries after his death. It was inevitable that such a state of affairs could not long continue, and the system eventually collapsed for economic and other reasons. Some of the kings were not above rewarding their favourites with funds misappropriated from the mortuary endowments of their predecessors.
With the passage of time each pyramid complex tended to be built smaller and smaller, and more and more crudely, although some exceptions there naturally were. By the latter part of Dynasty XII the main body of pyramids had degenerated to mud-brick, limestone being reserved merely for the internal chambers and passages and external casing. After Dynasty XIII no more pyramids were built, except some very degenerate examples not to be compared with those of the Old and Middle Kingdoms. Very soon afterwards the whole sixty-mile range of pyramids from Gîza to Maidûm had become a desert solitude.
