The present invention provides an engineering subcontracting treatment method and an engineering subcontracting treatment apparatus. The engineering subcontracting treatment method comprises: detecting whether a first entrance guard opening command is received, wherein the first entrance guard opening command is the command output by a first entrance guard card and used for indicating entrance guard equipment to be opened, and the first entrance guard card is the entrance guard card storing subcontracting personnel information; if receiving the first entrance guard opening command, detecting whether a second entrance guard opening command is received before receiving the first entrance guard opening command, wherein the second entrance guard opening command is the command output by a second entrance guard card and used for indicating the entrance guard equipment to be opened, and the second entrance guard card is the entrance guard card storing subcontracting management personnel information; and outputting alarm information if the second entrance guard opening command is not received before receiving the first entrance guard opening command. With the method and the apparatus of the present invention, the problem that the concurrent entering/leaving the engineering field of the subcontracting management personnel and the subcontracting personnel is difficultly ensured during the engineering subcontracting implementation process is solved.
