"The size of the hammering block was chosen to keep a very fast rate of tunnel building. That is why blocks were as big as possible. Their size was limited only by available methods of transport. Because they were transported by water the block weight was about 2,5 tons”.
The height of the tunnel was less than 10 m. The tunnel was cut out on the level that allowed it to be dry when Nile's water was low. When the water level raised up about 6 m, almost all stone blocks from the tunnel could be picked up by boats from their spot”.

”How, in ancient times, the difficult problem of boats loading and unloading process was solved explains the animation and drawing below”.

”Light, made out of cane, boats were put on the top of blocks and tided up with ropes. These transport boats
ware waiting for raising water of the Nile and they could be easily towed to a chosen destination. The simplest way was to haul them to the west side of the Nile where water flooded the fields.
Here they were left in the mud to be transported on the land after the flood was over”.
