Picture these scenarios: You've agonized to measure, double-check, and line up a complicated roofline, but after nailing up the rafters, you notice that the fascia lines are out of whack. Or, you've cut out all of your tair stringers, only to realize they don't fit and now you're racing rush-hour traffic to the lumberyard. Here are a few layout methods with built-in double-checks that can help solve problems before they start.
Layout Direction. When framing walls, pull all layout measurements from the same control point, and always move in the same direction, for example, start at the front of the building and always move left to right. The direction doesn't matter as long as it's the same throughout the building, including the second and third floors. Consistent layout direction ensures that studs, rafters, and joists align throughout construction. This makes life easier for installing duct work, pipes, or conduit later, leaving any bay useable as a chase throughout the structure.
Repeating Wall Patterns. Plate and detail any lined-up, same-dimension walls at the same time, so you only pull your tape once for multiple walls. For example, architects often load long hallways with closets that are usually the same size; cutting them and laying them out in one shot is easier, more accurate, and faster than laying them out as you go.
