COLVIN GRADING & SOILS, LLC

COLVIN GRADING & SOILS, LLC specializes in earthwork, site preparation, and soil stabilization services for public infrastructure projects. Their core capabilities include grading, compaction, erosion control, and subgrade preparation using heavy equipment and geotechnical best practices. The firm applies precision earthmoving techniques to meet civil engineering specifications for roads, utilities, and public facilities, with a focus on achieving proper drainage profiles, compaction density, and soil bearing capacity. Their technical expertise lies in interpreting soil borings, implementing ASTM-standard compaction testing, and executing cut-and-fill operations in compliance with federal and state environmental regulations. Key differentiators include adaptive site logistics planning and experience working in sensitive terrain where soil stability and runoff management are critical. Award history is not available to confirm specific agency relationships, so no definitive patterns of engagement with federal, state, or local entities can be inferred. The contractor’s work is typically aligned with civil construction scopes common in public works projects, but without award data, direct agency associations cannot be identified. The primary NAICS code 238910 — Other Heavy and Civil Engineering Construction — reflects a focus on large-scale earthwork and site development not covered under standard building or highway construction categories. This includes site preparation for public infrastructure such as drainage systems, embankments, and utility corridors. The firm positions itself within the civil construction niche, serving projects requiring specialized soil handling and earthmoving precision. COLVIN GRADING & SOILS, LLC is a small, locally based business structured as a 2J entity, operating from Stockton, Missouri. The company holds no federal certifications and maintains a regional footprint, likely serving state and municipal contracts in the Midwest. Their market positioning is grounded in hands-on earthwork execution rather than design or management services, emphasizing field proficiency and equipment-based delivery.
