Citrine LLC specializes in engineering and inspection services for critical federal infrastructure, with deep expertise in fire suppression system design, arc flash analysis, boiler safety inspections, and electrical system compliance. The company delivers technical solutions for building systems ranging from mechanical and electrical installations to structural integrity assessments, often supporting mission-critical facilities in defense, veterans’ healthcare, and federal research environments. Their work includes conceptual design, physical inspections of specialized equipment such as test tanks and generator systems, and ensuring adherence to NFPA, OSHA, and other federal safety codes. A key differentiator is their ability to execute complex inspections and engineering studies under stringent regulatory frameworks, particularly for high-risk environments like naval facilities and VA medical centers. Citrine maintains strong, recurring relationships with the Department of Veterans Affairs, where they provide building safety and generator commissioning services, and the Department of Defense, delivering engineering studies for fire detection systems and equipment validation. They also support the General Services Administration and Department of Commerce on construction-phase services, indicating a consistent role in facility modernization and lifecycle management across federal real property portfolios. Their primary focus is engineering services (NAICS 541330), with supplementary work in building inspection services (541350) and specialized technical support (541990). This positions them as a niche provider for safety-critical infrastructure projects requiring interdisciplinary engineering and compliance rigor, particularly in government-owned facilities with aging systems. Citrine LLC is a Women-Owned Small Business and Service-Disabled Veteran-Owned Small Business, reflecting a dual commitment to diversity and veteran-led leadership. Based in Lakewood, Colorado, the firm operates with a lean, specialized team focused on high-value, compliance-driven federal contracts, leveraging its certifications to compete in set-aside markets while maintaining technical excellence across defense, healthcare, and civilian infrastructure sectors.
