Petra Seismic Design built a reputation for trusted seismic expertise under Robert Simmons’ leadership grounded in accuracy, field awareness, and long-standing relationships.
At the same time, Synergy Engineering, led by Chris Scott, was building a broader delegated design platform rooted in those very same commitments: dependable engineering, code-compliant solutions, and collaborative partnership with contractors.
Seismic design remains core to what we do, but our capabilities now extend across the full spectrum of delegated engineering services for mechanical, electrical, plumbing, and specialty trades.
Our clients need:
That’s why we are aligning under one name (and a new digital home):
The name reflects the full scope of what we provide—and the direction we’re headed.
Hospitals. Schools. Emergency facilities. High-density residential buildings. The work we do may never be visible, but it must always perform. That responsibility remains unchanged.
Robert and Chris continue to play an important role in this next phase leading the expansion of our capabilities and reach. Together, this leadership reflects the same shared commitment that has always defined both organizations.
We exist to help contractors build safer, code-compliant structures; efficiently, reliably, and without unnecessary risk. Under one unified brand, we can do that more effectively, more consistently, and at a national scale.
Same commitment. Expanded capability.
