Segment Reporting [Abstract] |
Segment Reporting | # Note 9: Segment Reporting The Company has two reportable operating segments based on two primary areas of service. The Engineering and Other Scientific segment is a broad service group providing technical consulting in different practices primarily in engineering. The Environmental and Health segment provides services in the areas of environmental, epidemiology and health risk analysis. This segment provides a wide range of consulting services relating to environmental hazards and risks and the impact on both human health and the environment. Our Chief Executive Officer, the chief operating decision maker, reviews revenues and operating income for each of our reportable segments, but does not review total assets in evaluating segment performance and capital allocation. Segment information for the three and six months ended July 3, 2026 and July 4, 2025 follows: Revenues
