About ADAP Construction

More than 50 year experience in industry

ADAP Construction is a full-service general contractor, construction management firm and construction materials producer. Recognized as one of the top 25 largest construction companies, ADAP specializes in complex infrastructure projects, including transportation, industrial and federal contracting.

ADAP's strength is a combination of quartz and feldspar grains that have been slowly fused together over time. Quartz offers strength, luster and the glue that holds the material together, while feldspar brings color and a resistance to discoloration. Combined, quartz and feldspar are stronger than steel.


Our Legacy

Deeply embedded in our nearly 100-year history is a culture of hard work, honesty and getting the job done right. Our survival is not an accident. Hard work and unfaltering tenacity led us from quarrying granite rock, the stone that built the West, to paving the first roads into Yosemite and now to helping rebuild Ground Zero. ADAP is—and will continue to be—part of a story much bigger than itself.

Our Leadership

From the start, great leaders were the heart of ADAP and the visionaries that pushed our enterprise forward. Today is no different. Following in the footsteps of those before them, our leaders are driving ADAP to the next level of success by leading with integrity, cultivating our people, engineering new opportunities and continuously expanding and diversifying our business.


The work we do today will have an impact on countless future generations—and we don’t take the responsibility lightly. We follow a comprehensive approach to sustainability, one that reduces our environmental impact and fosters positive community interactions in all aspects of our business. It is our instinct to constantly seek out new solutions and to create meaningful and sustained change today, tomorrow and for years to come.
