COLUMBIA Technologies has applied our deep experience in governmental compliance, security, safety and documentation to dozens of remediation assessment projects for federal civilian and military agencies at sites all across the U.S.

As a Veteran-Owned Small Business, we have built COLUMBIA Technologies to be a responsive, reliable and high-value partner to the federal government. We bring to every engagement an intimate understanding of the challenges facing federal decision-makers and extensive experience with Performance Based Contracting.
