A builder's map is a type of document used by construction professionals to plan and manage the building process. It typically includes information such as the location of the building site, the layout of the building, and the materials needed for the project. The term 'PLAT' is a four-letter word that refers to a map or chart that shows the boundaries of a piece of land. A PLAT is often used in conjunction with a builder's map to provide a more detailed view of the area being built upon.
