Measure Ceiling Span

What happens here

A worker stands on a ladder and extends a tape measure across the span of the ceiling joists or framing where the new tongue-and-groove planks will be fitted. The measurement is called out as "134 and a half" (presumably inches), which will guide the cutting of the ceiling planks.

Goal: The first step involves accurately measuring the length of the ceiling area where the tongue-and-groove planks will be installed to determine the required plank length.
