Egypt's pyramids were built one bucketful at a time.

(Didn't you know that the Romans adapted their 'invention' of concrete
as a variation of the Egyption invention of the reconstituted
limestone which comprises pyramind construction technology?)

The massive blocks were cast in place using wooden forms oiled with
vegetable oil as a release agent. The height of the blocks made using
the wooden forms was determined by the height a slave could lift a
basket full of powdered limestone or a bucket full of brackish water.
Taller workers could have built bigger blocks. A hundred workers could
have carried 5 tons of limestone and water, enough to cast a single
huge block, in a single trip each up the pyramid.
