What term describes masonry construction fabricated in a location other than the job site?

The term that describes masonry construction fabricated in a location other than the job site is "prefabricated unit." This term specifically refers to components that are manufactured in a controlled environment, like a factory or workshop, and then transported to the job site for assembly.

Prefabrication allows for greater precision, quality control, and efficiency since the modules can be created without the variables present in outdoor construction conditions. Additionally, prefabricated units can reduce construction time on the job site, as workers can focus on assembling and erecting these components instead of building them from scratch.

While "modular unit" can sometimes overlap in meaning with prefabricated units, it usually refers specifically to larger pre-made sections or systems designed for easy assembly, rather than all types of prefabricated masonry. The other options do not accurately capture the essence of off-site fabrication for masonry construction principles.
