Civilian Agencies

Civilian agencies face growing demands to modernize infrastructure, improve resiliency, and maximize the value of public investments. We partner with clients to navigate complex environmental, structural, and safety requirements, while delivering practical solutions that support agency missions and long-term objectives.

With decades of federal experience and a team of planners, engineers, and project delivery professionals, we help civilian agencies streamline their complex infrastructure and facilities programs.

Military Programs

For more than three decades, we have partnered with the Department of Defense to deliver military construction projects across active installations, federal campuses, and mission-critical facilities nationwide. Our teams understand federal requirements, secure operational environments, and quality-driven delivery, providing compliant solutions that improve performance and operational readiness.

Civil Works

We support federal agencies with comprehensive civil works services that improve water resources, navigation systems, flood resilience, and ecosystem restoration. Our multidisciplinary teams deliver practical, sustainable solutions for federal infrastructure projects through every phase of project delivery, from planning and design to emergency response and construction support.

Environmental Solutions

We support federal agencies throughout the environmental compliance process, from early site assessments and permitting through remediation and long-term resource stewardship. Our integrated team delivers technically sound, legally defensible solutions that help projects advance while protecting natural and cultural resources.
