JIMMY CLOSNER & SONS CONSTRUCTION CO., INC.

JIMMY CLOSNER & SONS CONSTRUCTION CO., INC. specializes in civil construction services under NAICS 237310, focusing on heavy and civil engineering construction projects that require precision in earthmoving, grading, drainage systems, and infrastructure alignment. The firm delivers turnkey solutions for public works, including roadways, utilities, and site preparation, leveraging heavy equipment operations and construction management practices compliant with federal and state engineering standards. Their technical expertise includes surveying, soil stabilization, stormwater management, and adherence to DOT specifications, with an emphasis on safety protocols and schedule-driven execution in challenging terrain. Award history is not available to confirm specific agency relationships or project types, so no definitive patterns of engagement with federal, state, or local entities can be inferred. The contractor’s operational focus remains aligned with infrastructure development, but without recent award data, the scope of their client base or project scale cannot be characterized. The primary NAICS classification, 237310, reflects direct involvement in large-scale civil infrastructure, distinguishing the firm as a contractor capable of managing complex earthwork and utility relocation tasks. Their market positioning centers on regional public works contracts requiring field-tested execution, though vertical specializations beyond general civil construction cannot be determined from available data. The company is structured as a small business under the 2L entity classification and is headquartered in Mercedes, Texas. No government certifications are listed, and there is no public indication of DBE, SDB, or other socio-economic designations. Geographic presence is localized to South Texas, with operations likely serving regional transportation and municipal infrastructure needs. The firm’s business profile emphasizes hands-on construction delivery rather than administrative or consulting services.
