    Basic Foundation Caisson Pointers Needed

    thank you! darn earthquakes (for the lateral). ;-) so, my engineer will have to figure out the stiffness of the reinforced concrete to prevent buckling. A Y-shape should be able to nicely drop the load onto the single pillar. fortunately, going into the bedrock, I won't worry about needing...

    Basic Foundation Caisson Pointers Needed

    Thank you. I am trying to figure out basic economics --- when does it make sense to build on one giant pillar with a steel platform on top vs. when does it make sense to build on 4 pillars on the corners. Intuitively, the deeper the bedrock, the more I should prefer the single fat pillar. I...

    Basic Foundation Caisson Pointers Needed

    I am wondering whether caissons are expensive more because of the material, or because of the cost of drilling into bedrock. would it be more efficient to place one giant fat caisson that then forks above ground, or many thinner caissons that all have to be placed far down? where would I find...
