We started the day by measuring the distance from the steel frame to the walls at all hip and valley beam positions as well as selected other points. We wanted to confirm these distances so that we can order the LVL beams to make the hip & valley rafters at these points.
To measure the distance we placed our very long ladder against the steel frame and stretched a tape from the steel to the outside of the walls top plate.

We made 15 measurements and we a pleased to say they correspond to the drawing within 50mm (mostly within 30mm).
