  • “Switnerton Builders recently partnered with SOS Steel Co, Inc. on two projects at Wilcox High School in Santa Clara, CA – a new 3-story classroom building and a seismic upgrade and modernization for an existing 2-story classroom building.

    We found their work to be a top notch and appreciate their attention to detail. SOS Steel’s work as a Prime Trade Contractor was exceptional as each project provided a number of challenges, but through collaboration the challenges were quickly mitigated. Their wealth of experience and thinking “outside the box” helped keep our projects on schedule.

    SOS Steel offered competitive pricing on a consistent basis and often presented cost-saving alternatives to minimize change orders.

    We look forward to working with SOS Steel again in the future!”
