A method for transmitting data generated by a logger within a concrete mass and for displaying mechanical data to a device for outside the concrete mass. The method includes the step of sensing, processing, and recording the mechanical data generated by the logger within the concrete mass. The mechanical data is protected from alteration while the mechanical data is within the concrete mass. The mechanical data is transferred to an external device with a first protected transference protocol. The mechanical data is transferred to a computer with a second protected transference protocol. The mechanical data is decoded in the computer and displayed on a user interface.
