The term FAB ATTACHMENT can be broken down into three parts: PRE (3 letters), FAB, and ATTACHMENT. PRE stands for 'prefabricated, ' which is a type of construction that involves assembling components of a structure off-site and then transporting them to the building site. FAB is an acronym for 'FABRICATION, ' which is the process of creating something from raw materials. Finally, ATTACHMENT refers to the act of attaching something to another object. Together, these three terms refer to the process of attaching prefabricated components to a structure.
