Our Services

At SD Engineering LLC, we provide more than just technical drawings & reports.

We deliver the engineering certainty required to keep critical infrastructure operational. With over 35 years combined experience across the nuclear, semiconductor, aerospace, and food sectors, we specialize in identifying risks before they lead to failure.

As Licensed Professional Engineers, we bridge the gap between aging legacy systems and modern reliability standards. Whether you are navigating an equipment obsolescence crisis, requiring medium-voltage cable diagnostics, or seeking a third-party safety net for new designs, we provide the technical rigor and senior-level oversight your facility deserves.

Obsolescence Audits

We conduct a deep-dive analysis of your electrical and controls infrastructure to identify aging components and critical failure points.

You receive a prioritized replacement roadmap, allowing you to manage capital expenditures proactively rather than reacting to emergencies.

MV Cable Testing

Utilizing advanced diagnostics like VLF and Tan Delta testing, we provide a professional assessment of your cable health.

Our data-driven approach moves you from "guessing" to "knowing," ensuring your underground and facility feeders are prepared for long-term service.

Initial designs and third-party reviews, backed by senior-level engineers with Professional Engineering (P.E.) credentials

We verify code compliance, reliability, and safety before construction begins, preventing costly field changes and ensuring the final installation meets your specific operational standards.
