ROOF CORE SAMPLE DEPTH - PHOTO.pdf

This is an image of a measurement demonstration on a concrete surface. The photograph shows a person holding a yellow and black tape measure extended across a hole or depression in what appears to be a concrete pavement or slab. The tape measure displays measurements with visible numerals ranging from approximately 2 to 7 inches. The hole appears to be roughly circular and approximately 3 inches in diameter based on the tape measure positioning. Adjacent to the measured hole is scattered concrete debris or aggregate material, suggesting the hole may have resulted from concrete deterioration, spalling, or removal. The image appears to be a documentation or inspection photograph, possibly for quality assurance, damage assessment, or construction defect evaluation purposes.
