What are floor-grade instruments?

Floor-grade instruments are specialized tools used in construction and surveying to ensure level surfaces and accurate measurements on the ground. These instruments, which include levels, theodolites, and total stations, are designed to operate effectively at or near the ground level, facilitating precise alignment and grading. They are essential for tasks such as laying foundations, grading land, and ensuring proper drainage. By providing accurate readings, floor-grade instruments help maintain the integrity and quality of construction projects.
