Floor Elevation Surveys
Floor elevation surveys are a useful tool for evaluating possible areas of settlement across the floor surface.
Floor elevation surveys are typically conducted with a gas or water-filled manometer. Floor elevation measurements are generally collected on an approximate 5 to 10 foot grid system where applicable. Two readings are collected across areas where a change in flooring materials occurred. This is done to determine the necessary correction to account for a change in floor elevations due to changes in floor coverings.
The floor elevation data is contoured using Surfer™, a computer-contouring program. The base map is digitized and the corresponding elevation data entered into a spreadsheet, where the elevations are corrected to ‘zero’ based on the lowest elevation recorded.
