Colas Construction

At Colas Construction (COLAS), we are raising the standard for quality construction with a focus on sustainability, equity, and access to opportunity—we build to inspire community. We prioritize people over profits and take pride in being a leader in commercial real estate and construction. Our story began in 1997 in Portland, Oregon, a city we proudly call home. Today, our work extends throughout the Portland Metro and SW Washington, building community through projects that make a lasting impact. Founded by Hermann Colas, Jr, a scholar, U.S. Veteran, and proud Haitian American, COLAS remains true to its values: we build with excellence, integrity, and purpose, dedicating resources to lift others as we climb. COLAS is honored to be recognized as the #1 Most Admired Company in Commercial Real Estate & Development (2024) and to have been named among Oregon’s Most Admired Companies each consecutive year since 2018 by the Portland Business Journal. We are also proud that our Centennial Place Apartments project was named Top Project of the Year (2024) by DJC Oregon. As the only construction firm to earn both the Outstanding Rose Award and the Grand Rose Award by AGC Oregon for safety in construction (2020 and 2021), COLAS is proud to be nationally known for safety, sustainability, and excellence, reflecting our unwavering commitment to our mission: to build legacies and strengthen communities. At COLAS, we’re Building Tomorrow, Today!
