Interoperable Systems Group LLC specializes in developing and sustaining mission-critical software systems for tactical data link interoperability and command and control environments within the Department of Defense. Their core capabilities center on the delivery, licensing, and integration of specialized software tools such as MANDRIL and CIVET, which enable secure, real-time data exchange across joint and coalition platforms. The firm provides end-to-end support for tactical communications systems, including software subscriptions, system updates, and training for electronic systems management toolsets like ESMART, ensuring seamless interoperability across legacy and modernized military networks. Technical expertise includes embedded communications protocols, link-level data standards, and DoD-compliant software lifecycle management, with a focus on maintaining operational readiness through continuous software sustainment and configuration control. The company maintains a consistent and deep relationship with the Department of Defense, delivering software solutions that enhance situational awareness, data fusion, and cross-platform communication for aviation, naval, and ground forces. Their work directly supports joint all-domain operations by enabling interoperability between disparate tactical systems, reinforcing the DoD’s imperative for secure, scalable, and resilient communications architectures. Interoperable Systems Group LLC operates primarily within NAICS 513210, focusing on the publishing and sustainment of proprietary defense-grade software applications rather than general-purpose commercial software. Their market positioning is niche and mission-driven, serving specialized defense communications and C4ISR modernization markets where interoperability, certification, and operational continuity are non-negotiable. As a small business structured as a 2L entity based in Fort Worth, Texas, the company leverages its agility to respond to urgent DoD software sustainment needs. While currently holding no formal government certifications, its consistent award history demonstrates proven reliability in delivering high-assurance software systems to critical national defense missions.

Fire Alarm engineering for Lewis County
Solicitation # 2026-RFQ-040
Lewis County is soliciting qualifications under solicitation 2026-RFQ-040 for a professional engineering firm to provide comprehensive design and engineering services for fire alarm systems. The project encompasses several County-owned facilities, including the IT Building, Historic Courthouse, Health Building, and Lewis County Jail. The selected firm will be responsible for conducting on-site evaluations to determine the remaining useful life of existing systems, assessing code compliance with NFPA 72, IBC, and IFC standards, and developing bid-ready construction drawings and technical specifications. All designs must be stamped by a licensed electrical engineer familiar with Washington State fire alarm requirements and must integrate smoothly with existing infrastructure to ensure standardized maintenance and operations. Proposals are due by November 10, 2026, via the OpenGov platform and will be evaluated by a committee of at least three County employees using a points-based system. The evaluation criteria are equally weighted at 20 percent each across four categories: firm qualifications (including NICET certifications and licensed engineer availability), responsiveness and capacity to begin work within 30 days, regulatory compliance and permitting records, and the clarity and detail of blueprint designs. Applicants must provide a statement of qualifications, three public agency references from the last five years, and resumes of key personnel. The contract is administered by Matt Patana, Capital Infrastructure Specialist, based in Chehalis, Washington.
