To assess damage of the building resulting from excessive loads, fire, weathering effect, abnormal exposure condition, aggressive environment, corrosion of steel, lack of maintenance or due to natural calamities like earthquake, cyclone, heavy rain, flooding, etc.

For preparing as-built record and condition mapping of the building with reference to strength and quality of concrete and distribution of reinforcement for each structural member.

For Quality Assurance and Quality Control of ongoing construction by ascertaining in-situ strength, quality and condition of concrete. To verify the position, diameter and cover to embedded reinforcement.

To obtain various in-situ parameters like strength, modulus of elasticity, quality, location, diameter and cover to reinforcement, depth of carbonation, chloride content, core strength of concrete, vibrations of buildings, crack depth penetration, etc.

For understanding dynamic behavior of buildings by measuring vibration parameters like amplitude of displacement, velocity and acceleration.
