A ground-penetrating radar (GPR) survey was carried out in connection with the construction of a traffic bypass tunnel between Saraikale Khan and Dr. Zakir Hussain Marg in Delhi. Five boreholes were drilled in this area to correlate and confirm the GPR signatures with borehole data. This Note covers the correlation of the borehole data with GPR signature to explore the real subsurface strata conditions for the construction of the bypass tunnel.
