Multi-disciplinary consulting firm for transportation, structural, and civil engineering
Mannik & Smith Group is a 70-year-old civil engineering and design consultancy operating across transportation, structural, environmental, and site planning disciplines. The company's engineering-heavy hiring mix (129 of 166 active roles) and focus on process improvement reflect efforts to scale design capacity and deepen structural and transportation practices—both named as expansion priorities. Active technology adoption of Civil 3D, paired with a mature stack spanning AutoCAD, MicroStation, and hydraulic/structural analysis tools (HydroCAD, STAAD, SAP2000), indicates a firm managing complex infrastructure projects while modernizing design workflows.
