Industry-standard construction tolerances dictate the appropriate precision of dimensions. Reference grids are like the glue that ties all of the engineering and architectural drawings together. You should be able to trace every dimension to its closest column line. Here are the six most common types of symbols you will find on floor plans (versus other types of plans). Blueprints are typically drawn on a -inch scale, which means every quarter-inch on the plan equals 1 foot of actual length on the completed structure.
