Which specification format is older and more commonly used?

• A. MasterFormat: by material
• B. Uniformat: by system
• C. MasterFormat: by system
• D. Uniformat: by material

Answer: (A)

MasterFormat organized by material has long been the standard for construction specifications. It was established earlier and became the default way to structure specifications across divisions by material and work results, which makes it the most familiar and widely adopted format for procurement and project documentation. Uniformat, by contrast, is a newer approach that groups information by systems for purposes like cost estimating and lifecycle analysis, rather than detailed spec production. Because of its longer history and broader usage in general specifications, MasterFormat: by material is the older and more commonly used option.
