Site surveying requires reading the E-Staff or levelling Rod or simply surveying measuring staff. This video will give you a brief idea on how to read a staff in civil engineering surveying.
Reading the E-Staff or rod is a skill expected from a construction, civil engineering and surveying students and professional. This video will walk you through steps on how to read the Staff easily, especially for beginners.
SURVEYING: What is the Top, Middle and Bottom Hairs STAFF Readings?
#kelvinAcademy #kelvinAcademyVideos
Site engineering involves using various instruments and methods to prepare the construction site for the substructures or for the superstructure. A lot of tasks must be completed before other construction professionals can carry out their specific roles on that site. At times, an architect will want the land surveyor to complete their tasks before they can fully develop their own architectural plans for the project.

Hi

[@user-ly8uq4io9l]

Please 🙏🙏 help me with this question. If the bottom stadia hair reading on the staff is 0.712 cm ,the middle hair reading is 0.889 cm, find the upper hair reading

[@emmanuelnwosu1262]

The Upper Hair reading is 1.066cm
