MERIDIAN ENGINEERING CO

Meridian Engineering Co. specializes in heavy civil infrastructure construction, with deep expertise in highway, street, and bridge systems as well as specialized floodplain, levee, and dam modifications. The firm delivers mission-critical civil works for federal land management and diplomatic facilities, including road rehabilitation, trailhead and campground infrastructure upgrades, and structural flood control systems. Their technical proficiency spans earthwork grading, drainage design, erosion control, concrete retaining structures, and geotechnical stabilization—particularly in sensitive environmental zones. Meridian’s ability to execute complex, multi-site task orders under IDIQ vehicles demonstrates strong project management discipline and adaptability in remote or constrained environments, often working within federally protected or ecologically sensitive areas. The company maintains consistent relationships with the Department of State, where it has delivered critical levee and floodplain repairs to protect diplomatic infrastructure, and with the Department of the Interior and Department of Agriculture, performing dam modifications and forest service road rehabilitation. These engagements reflect a pattern of trusted execution on high-stakes, publicly funded civil works requiring compliance with federal environmental and safety standards. Meridian’s primary focus lies in NAICS 237310 (highway, street, and bridge construction) and 237990 (other heavy and civil engineering construction), positioning them as a niche provider of non-residential, federally funded infrastructure projects. Their work supports transportation networks, water resource management, and public land access systems, serving agencies responsible for national infrastructure resilience and public safety. Meridian Engineering Co. is a small business structured as a 2L entity, headquartered in Tucson, Arizona. While currently holding no formal government certifications, its track record of successful delivery on complex civil engineering tasks underscores its credibility within the federal construction market. The firm operates with a regional footprint centered in the Southwest, serving agencies with geographically dispersed infrastructure needs.
