Q1: (15 Marks)
Your company has been requested to evaluate the concrete compressive strength of a parking garage structure. In a discussion with the owner, the owner has suggested to take cores in different locations of the structure. However, since you are an NDT expert, you have suggested an alternative way of evaluating the strength without causing any damage to the structure. Which NDT do you suggest to the owner and why? Rank the compressive strength of A1, A2 and A3 from highest to lowest.
