Material Discovery & Construction Assessment

What happens here

During the demolition of the first wall, the worker notices that the existing drywall is very thin, approximately quarter-inch thick, indicating poor quality or older construction. He also observes particleboard used in some areas, which he initially misidentifies as being from the late 70s or early 80s (though technically it originated earlier). He deduces that the section being demolished was likely an addition to the original house, as it features different construction materials like wood planks for sheathing instead of OSB on the exterior. This discovery highlights the need for careful inspection and adaptation during renovation.

Goal: Identify and analyze existing construction materials to inform further demolition.
