I thought this would be an interesting comparison. My folks were in Ethiopia last year and got to witness the construction of a new dormitory on the campus of an institution there. We are so dependent upon technology, so it's amazing to see what can be done with two very standard pieces of power equipment, and a bunch of people. Granted, time is a different story there... Enjoy!
Getting gravel to the mixer.
All concrete for this entire project mixed in a mortar mixer.
The mortar mixer and hoist are the only power equipment utilized, and even the latter was only used when the ramp (see below) was out of reach of the very top of the building.
Concrete bucket hoisted up through the intricate scaffolding assembly.
Would you wheelbarrow a full load of concrete up this ramp...barefoot?
This man and woman haul concrete up the scaffold ramp at a nearby building.
The entire structure is reinforced concrete alone. It will be infilled with handmade concrete blocks (below).
Hand made cinder blocks laid out to dry.
Each cast-in-place slab is shored up with small tree trunks.
Central triangular atrium.
This dormitory will house 400 students, just a few less than our project in Durham.
