Overview
What is a Highway Survey?
A highway survey is a large-scale route survey specifically tailored for major arterial roads, national highways (NH), and state highways (SH). It requires establishing a highly accurate DGPS control network over long distances, detailed topographic mapping of a wide corridor, and precise levelling for pavement and drainage design.
Why is it Required?
Highways involve immense capital investment and strict design standards (NHAI/MoRTH). Survey data must be flawless to design grade separators, interchanges, bridges, and ensure safety at high speeds. It also identifies land acquisition limits and utility relocation requirements.
Who Needs it?
National Highways Authority of India (NHAI), State Highway Departments, concessionaires, EPC contractors, and highway design consultants.
