QUADRANT CONSTRUCTION INC

Quadrant Construction Inc. specializes in civil infrastructure and facility maintenance for military installations, with deep expertise in highway, street, and bridge construction as well as commercial and institutional building systems. The contractor delivers precision earthwork, pavement rehabilitation, drainage improvements, sediment control, fencing, signage, and utility upgrades—including 440V/200A electrical service installations—on active Department of Defense sites. Their work involves complex site logistics, temporary structure deployment, and compliance with military engineering standards for safety, durability, and rapid turnaround in operational environments. Technical proficiency includes concrete repair, stair and structural element restoration, and infrastructure asset preservation under strict DoD regulatory frameworks. The company maintains a consistent, long-term relationship with the Department of Defense, executing mission-critical construction and maintenance tasks across multiple military bases. Their portfolio reflects a focus on facility sustainment, base readiness, and small-scale civil works projects that support daily operations and force readiness, often under time-sensitive task order requirements. Work is delivered with an emphasis on minimal disruption to active installations and adherence to military construction codes and environmental compliance protocols. Quadrant’s primary industry focus lies in NAICS 237310 (Highway, Street, and Bridge Construction) and 236220 (Commercial and Institutional Building Construction), positioning them as a niche provider of on-base infrastructure services. They specialize in the repair, upgrade, and maintenance of military-owned roads, walkways, buildings, and utility systems rather than new construction, distinguishing themselves as a responsive maintenance and sustainment contractor within the defense built environment. Based in Jacksonville, NC, Quadrant Construction Inc. operates as a small business under entity structure 2K with no federal certifications on record. Their geographic proximity to major military installations in the Southeast supports rapid mobilization and sustained on-site presence, reinforcing their role as a trusted local partner for DoD facility readiness initiatives.
