About HNTB

The orange square is what we call the HNTB Spark.

It’s infused every HNTB project since our founding in 1914. The Spark is inspiration, the fire of new ideas and a source of illumination.

And, of course, the HNTB Spark builds. It builds technical knowledge, consensus among competing stakeholders, and understanding between policymakers and the public.




The most visible and powerful symbol of our vision is the HNTB signature. The square on the H represents individual personal commitment — from HNTB to a client, a community and employee. The color orange represents the Spark of imagination that HNTB brings to any situation. It symbolizes HNTB's unique approach to identifying and solving complex issues.
