Scope of Work:	GPR investigation to to map the underground foundation of pillars, depth of rock profiling and discrepancies in it up to the depth of 6 m.
Location:	Nepanagar, Madhya Pradesh.
Client:	Nepa Limited
Equipment:	GSSI SIR 4000 equipped with 200 MHz and 400 MHz center frequency antennas.
Challenges:	It was running construction site, very old building, visibility issues and boulders beneath the ground in sloppy manner.
Summary:	The GPR survey has been carried out in 60 years old newsprint paper mill, Nepa Mills Limited, Nepanagar, Madhya Pradesh. The mill is currently in non-operating condition since long. Since the mill is planned to be resumed for production of paper again, a new installations have been planned. Structure being very old need intense repair and maintenance of the columns and foundations to take care pf the additional loads due to new installations and considering the age of the building. The scope of the survey was to map the underground foundation of pillars, depth of rock profiling and discrepancies in it up to the depth of 6 m using non-destructive Ground Penetrating Radar technology. So that the effective maintenance can be further planned and executed. Considering the client's requirements and the expected depth of the anomalies, the area has been surveyed using 400 MHz and 200 MHz centre frequency antennas mounted with SIR 4000 GPR systems to cover the depth up to 6 m with a fair resolution.
