Plumbness
“Plumb lines, inverted plumb lines, and optical plummets are designed to accurately measure bending, tilting, or deflection of concrete structures resulting from external loading to the structure, temperature changes within the structure, sliding of the structures, or deformation of the foundation. Through the measurement of structural deformations, they will furnish information in regard to the general elastic behavior of the entire structure and foundation, provide a means for determining the elastic shape of the deflected structure which will permit separation of lead deflection and thermal deflection components, and, with precise alignment data, provide for estimating the amount of translation or sliding”.[1]
