C. S. & W. Contractors, Inc.

C. S. & W. Contractors, Inc., operating as CSW Contractors, was founded in 1982 in Scottsdale, Arizona. The company began as a heavy civil construction contractor serving both private and public sector clients throughout the Southwest United States. Over time, CSW has developed specialized capabilities supporting large-scale infrastructure and renewable energy projects—particularly utility-scale solar installations—acting as an installation subcontractor for major developers and EPCs.
CSW’s reputation is built on its commitment to quality workmanship, safety standards, and successful project delivery—a legacy established by its founders that continues under current ownership and leadership. With several decades of experience in earthwork/site development and infrastructure support for renewable energy facilities (including grading/earthmoving for large photovoltaic arrays), CSW has contributed to numerous high-profile utility-scale solar projects across Arizona and neighboring states.
The company employs between 250–499 people according to industry directories, reflecting its capacity to handle complex multi-million-dollar contracts while maintaining strong relationships with general contractors and developers within the clean energy sector.
