What is the process for lally column replacement in a building structure?

The process for lally column replacement in a building structure involves first identifying the column that needs to be replaced. Next, temporary support is put in place to hold up the structure while the old column is removed. A new lally column is then installed in the same location and adjusted to support the load of the structure. Finally, the temporary support is removed once the new column is securely in place. It is important to consult with a structural engineer or contractor to ensure the replacement is done correctly and safely.
