Structural Fix is a way to make changes to something like a building or a machine to make it stronger and safer. Structural Fix usually involves adding things to the building or machine so it can hold up better and last longer. For example, if an old building needs to be stronger, engineers might add beams or other pieces of building material to make it stronger. Or if a machine needs to be more reliable so it won't break down, technicians might add more pieces to make the machine stronger.
