The guys that worked for me last year have been busy with other projects over the winter and I told them when other work runs out I would have a project or two. This project is to build an awning (marquesina) along the whole side of the house. We built one but lower and it's only about a foot wide. I wanted more shade and rain protection. This will also be above the air vents which leaked in the past.
The circular support columns will be four with a diameter of 25cms which should give good scale to the house and the awning will be at least a meter and a half wide. I was surprised the footings will be the size of house footings -- a meter deep and filled with rock and cement. I was also surprised to find the Sonotubes were not that expensive. These were only $145 pesos and 3 meters long.
The most interesting thing is that they can't use the normal rectangular rebar design in a round tube so we bought a bunch (40 kilos) of wire that's about a 1/4 inch thick. They form it by wrapping it around a 6" drainage pipe until they have a slinky that stretches to 3 meters. Then they wire wrap 4 pieces of rebar inside. I imagine this will take the better part of a month.

Three of the column supports made - and holes where they will go in the grass
