Celebrating 25 years

It all started on March 10, 1992, when some colleagues decided to re-engineer the concept of engineering firms. Quincy Engineering was born out of a strong desire to do the right thing for clients and design the highest quality, safest bridges and roads. Fast forward 25 years, and we’ve expanded our services and designed and delivered hundreds of projects throughout California, Oregon and Nevada.
