A device of gold color metal and enamel 1 1/4 inches (3.18cm) in height overall consisting of a white disc divided into three sections by a blue triaxial bar, its vertical axis containing a gold plumb line and bob all enclosed by a red ring bearing in the upper half the motto "SERVING BY BUILDING" in gold letters and on the lower half six gold rectangles divided three and three by the point of the plumb bob; around the ring twelve gold rays curved clockwise in the left side and straight on the right side.
Red and white are the colors of the Engineer Corps. The three-branched device in the center is symbolic of the forks of the Chicago River, alluding to the organization's home area. The plumb line relates to the function of surveying, the rectangles suggest building materials and the wheel itself simulates the wheel of a trench-digging machine.
The distinctive unit insignia was originally approved for the 416th Engineer Brigade on 2 Jan 1968. It was redesignated for the 416th Engineer Command on 11 Apr 1968.
