IADD, LLC

IADD, LLC specializes in geotechnical drilling and field testing services for transportation infrastructure projects, with demonstrated expertise in subsurface investigation and soil characterization for highway and road construction. Their work on the CA FLAP ALP 4(1) Hot Spring Road project indicates proficiency in executing precise borehole drilling, in-situ testing, and sample collection to support geotechnical engineering assessments. The firm’s technical focus centers on soil sampling, borehole logging, and data collection critical to foundation design, slope stability analysis, and pavement engineering—services essential to ensuring long-term structural integrity in civil works. Their capability is narrowly tailored to field-based geotechnical data acquisition, positioning them as a specialized contractor for agencies requiring reliable subsurface information during project planning and construction phases. The company has performed work exclusively for the Department of Transportation, delivering field-based geotechnical services that support roadway alignment, embankment construction, and drainage system design. Their relationship with this agency reflects a consistent focus on transportation infrastructure lifecycle support, particularly in pre-construction subsurface characterization. IADD, LLC operates within the Testing Laboratories and Services NAICS category (541380), which encompasses field-based geotechnical investigations and laboratory-supported soil analysis. Their market positioning is that of a niche provider focused on high-precision drilling and sampling for civil engineering applications, rather than broad-spectrum lab testing or environmental remediation. The company is headquartered in Toomsuba, Mississippi, with no publicly listed certifications. Its operational footprint appears localized, serving federal transportation initiatives primarily in the southeastern United States. As a small, independently operated entity, IADD, LLC fills a critical role in delivering on-site geotechnical data essential to safe and compliant infrastructure development.
