EC Source Services, LLC Tech Stack

EPC program management for Extra High Voltage transmission and substation projects

Construction Mesa, Arizona 201–500 employees Public Company

EC Source is a full-service EPC contractor focused on large-scale electrical transmission infrastructure across North America. The tech stack reveals a traditional heavy-construction operation anchored in domain-specific simulators (ETAP, PSCAD) and design tools (AutoCAD, Revit, Civil 3D), paired with project-management and geospatial layers (Procore, Primavera P6, ArcGIS). Active hiring is construction-led (22 roles) with parallel engineering expansion (20 roles), aligned to ongoing HVDC transmission and substation projects; pain-point intensity around safety compliance, cost tracking, and subcontractor coordination suggests operational scaling pressure.
