The rate of speed of earthbag wall building will naturally vary from project to project, depending on the number, strength and skill of workers, complexity of design, how far materials have to be moved, etc. But let’s examine the Somos Children’s Village since Cecilia Rodriguez, architectural intern and project manager, has measured their production rate.
Owen: How many linear meters of tubes do you place per 8 hour day?
Cecilia: 150 linear meters are placed per day. (492 lineal feet or about 1.6 football fields)
Owen: How many workers are there filling and tamping?
Cecilia: Normally we had one or two persons mixing mix, three carrying the soil, three filling the bag and one or two tamping behind. (total = 8-10 workers)
Note on the Project Somos Children’s Village Slideshow. This slideshow has photos of each step of construction so it’s easy to visualize their project. It looks like they’re doing a great job.
You can also watch the slideshow on Picasa, where it’s easy to study each photo as long as you want.
