Patrick provided Subsurface Utility Engineering (SUE) at an industrial facility in the Midwest. The utilities needed to be identified and then located to determine if they would be in conflict of a future project. Patrick performed all Quality Levels for SUE (D, C, B, and then A) in accordance to the American Society of Civil Engineers SUE Guidelines 38-02. Starting with a limited number of utility atlases, Patrick searched for and surveyed visible above-ground evidence of utilities in the project area and then traced utilities based on apparent utility appurtenances that were above ground, such as water pipes and electrical conduits. The team also opened up utility sewer structures to note the depth, size, and direction of the utility to connected to them by adjacent structures. Based on the engineer's design, specific areas were identified as potential conflicts between the existing utilities and the proposed project. Patrick then engaged a potholing contractor to expose the utilities to obtain the actual location and the depth below ground.
