Services
Security Design
Our security design services create holistic protection systems for government facilities. We specialize in blast mitigation, anti-terrorism measures, and infrastructure hardening against chemical, biological, and radiological threats. Our engineers implement advanced access control systems, surveillance networks, and energy security solutions for mission-critical operations.
Munitions Modernization
We provide comprehensive modernization for military munitions facilities. Our services include automated production line design, lean manufacturing implementation, and AI-driven safety systems. We specialize in upgrading legacy infrastructure at Army Ammunition Plants and Naval Surface Warfare Centers with smart manufacturing technologies.
BIM/CIM Services
Our Building Information Modeling team creates 3D digital twins for facility lifecycle management. We use laser scanning, VR/AR visualization, and Dynamo automation to enhance design coordination. These technologies improve stakeholder engagement and reduce construction errors through clash detection and model-based reviews.
Commissioning
We ensure optimal building performance through comprehensive commissioning services. Our certified agents test mechanical, electrical, and fire protection systems to meet federal energy standards. We provide retrocommissioning for existing facilities and life safety system validation for new constructions.
Engineering
Our multidisciplinary engineering covers civil, structural, and mechanical systems for high-security facilities. We integrate blast-resistant design with sustainable building practices. Our team specializes in mission-critical infrastructure including SCIF spaces, command centers, and secure data facilities.
