We began excavation for the caissons today. Caissons are deep concrete structures that penetrate poor soil at the surface and bear on bedrock below it. On this project they are typically 20' deep x 2' wide. They typically cost $200/ft. so a 20 ft. deep caisson is around $4,000. Since we're the general contractors and hired the drill rig, concrete, and rebar separately we are getting it done for about $130/ft. There are 17 caissons total. So far we hit groundwater in one of them.

Its permanent now. Thousands of pounds of concrete were poured today. Warren, the pump truck operator, is the same guy that pumped the footings on Patton 7 years ago. Since then he donated his kidney to his sister when she caught some rare virus.
