Thinking and problem solving are done in a number of ways in the field.
The image of frame and pier position captures, not a static series of construction markers depicting an order to work, but is rather a working sketch. Done with an inverted paint or chalk can, lines can be drawn and then erased by scratching away the surface one painted on. This helps one (me) think about different possible layouts and to visualize the issues that had not yet been thought of. Oftentimes I am working with multiple colors - white, pink, and orange. Here, at one point a couple loose brick chips were used in the sketch, string lines were laid out, pins were set, and a 2x4 was used as a straight edge.
