Craftsmen measure and mark their work according to definable general principles, often without even realizing it. Carpenters, masons, and roofers, for instance, all keep their work straight by using the same simple tool: a length of string. There are any number of situations in which builders use the same tool and the same basic approach to measure and mark very different materials. The reason for this is simple: As varied as the materials may be, the essential goals of professions in the building trades are the same. They want their work to be neat and professional looking, and they rely on the neat and professional work of other tradesmen. Almost without exception, professionals in the trades want level floors, plumb walls, and square corners; they want even, orderly courses; they want crisp, straight lines of graceful curves. On most jobs, they also have to make good time to make a living wage.
In working toward these common goals, professionals in the trades face similar sets of problems, and they turn time and time again to the same proven measuring and marking techniques to help solve them. The ten rules presented here are basic, time-tested approaches that professionals use to solve common and, in most cases, age-old measuring and marking problems.
