DERIAN, INC.

DERIAN, INC. specializes in heavy civil construction projects focused on critical infrastructure repair and engineering solutions, particularly for defense-related facilities. Their core capabilities include the design and execution of stream crossing repairs, which require precise hydraulic modeling, erosion control, and structural reinforcement using reinforced concrete and culvert systems. They also deliver specialized civil engineering services such as low sump foot valve installations, indicating expertise in hydraulic control systems, drainage infrastructure, and subsurface utility integration within constrained environments. The contractor demonstrates proficiency in site-specific geotechnical adaptations, stormwater management, and compliance with military installation environmental and safety standards, distinguishing themselves through hands-on execution of complex, mission-critical civil works in sensitive operational zones. The company maintains a consistent relationship with the Department of Defense, delivering infrastructure resilience projects that support military readiness. Their work includes repairing transportation corridors and installing hydraulic control components on defense bases, suggesting familiarity with DoD’s Facility Condition Assessment protocols and military construction specifications. This recurring engagement reflects a trusted partnership built on delivering reliable, timely civil works under stringent operational constraints. DERIAN, INC. operates primarily within NAICS 237310 (Highway, Street, and Bridge Construction) and 237990 (Other Heavy and Civil Engineering Construction), focusing on non-residential, public-sector infrastructure requiring heavy equipment, earthmoving, and structural integrity management. Their vertical specialization lies in transportation and hydraulic infrastructure within federal installations, positioning them as a niche provider for defense-centric civil works rather than commercial or municipal projects. As a small business structured as a 2L entity based in Everett, Washington, DERIAN, INC. leverages its Pacific Northwest location to support West Coast defense installations. The company holds no formal government certifications but demonstrates operational credibility through direct execution of complex, mission-essential projects for federal clients.
