Foundations · Columns
Do new columns need new foundations?
Usually yes. A new column needs a footing designed for its load, and a soil test is required for the new substructure.
The short answer
Usually yes. A new column carries load down to the ground, so it needs a footing designed for that load, unless it sits on an existing structure that has been checked and can carry it. Wherever a new substructure is built, a soil test is required. Structural Solutions designs the column and foundation and prepares stamped calculations for the approvals.
