The AfH Haiti team is conducting soils testing at a new school campus site in Port-au-Prince. We've brought in a French team of soils experts who are taking core samples at the site. The tripod helps drive a 10-20' pile into the earth, which, when pulled out preserves the order of layers of soil students will soon be standing over. This core sample is taken to a makeshift soils lab where core samples from several places around the site are reviewed.
The soil consistency determines how deep foundations must go to support the school buildings. It will also determine how large the buildings can be, although that is less of a concern when all new schools in Haiti are required to have two or fewer stories.
