What we do

Two kinds of clients, one engineering team.

We work for heavy civil and underground contractors on the temporary and permanent works that get structures built, and for owners, developers and builders on the buildings and sites themselves.

Our team

The team behind your plans

Scott O'Connor, PE

Principal Engineer & Founder

Scott founded OC Structural Solutions in 2022 after more than a decade engineering bridges and temporary works from the contractor's side. At Atkinson Construction, OHL USA and Flatiron, he designed and checked falsework, shoring, crane picks and demolition plans on major Southern California design-build programs, including the SR-91 Corridor, the I-405 Improvement Project and the LAX Automated People Mover.

That background shapes how OCSS works today: practical, buildable plans, delivered quickly, by the engineer who will stand behind them in the field.
