The phrase refers to a specific surveying instrument utilized for establishing or verifying points on the same horizontal plane. This tool is commonly employed in construction, engineering, and surveying projects to ensure accurate leveling across a site. As an example, it can be used to determine the precise elevation difference between two distant points, essential for tasks such as foundation laying or drainage system installation.
These instruments are crucial for achieving precision in projects where horizontal accuracy is paramount. Their use minimizes errors, reduces material waste, and ultimately contributes to the structural integrity and longevity of the finished work. Historically, these devices represent a significant advancement over earlier leveling methods, offering greater efficiency and reliability in the field.
