A new constructive method is proposed for the concrete strength of existing building. Nondestructive test methods for existing buildings had been widely accepted in practical engineering, the lower and upper confidence limits are given by using the inverse regression method, then a strong-weak qualified constructive method is presented according to the confidence limits. More rational constructive results of concrete strength can be obtained than the custom methods. Furthermore, an example of practical engineering is given. The results showed that the constructive method can provide reference value for the actual engineering, establish foundation for further emendation of "technical specification for inspection of concrete compressive strength by the nondestructive methods".
