Introduction
Have you ever wondered how electricity cables stay safe under the ground? Or how engineers stop water from damaging roads, buildings, and power lines? The answer is proper survey work.
Today, modern cities need safe electricity systems and strong drainage systems. Before any underground cable or drainage line is installed. engineers must carefully study the land. This process is called Under Ground Power Cable Line, Drainage System Survey.
Without proper survey work, many problems can happen. Roads may crack. Water may collect in low areas. Underground cables may get damaged. Sometimes accidents also happen because of wrong measurements.
That is why survey work is one of the most important steps before construction starts.
