GAHAGAN & BRYANT ASSOCIATES INC

Gahagan & Bryant Associates Inc. specializes in high-precision surveying and mapping services, with a focus on orthophotography and LiDAR data collection for civil infrastructure and flood risk management projects. The firm delivers geospatial intelligence through airborne sensing technologies, generating accurate topographic models and terrain datasets essential for hydraulic modeling, erosion analysis, and emergency planning. Their technical expertise includes airborne sensor integration, point cloud processing, digital elevation model generation, and georeferenced imagery production, all aligned with federal geospatial standards. The company distinguishes itself through its ability to deliver mission-critical spatial data under demanding environmental conditions, supporting engineering and environmental decision-making in sensitive watersheds. The contractor has demonstrated direct experience supporting the Department of Defense on civil works and infrastructure resilience initiatives, particularly in hydrologic and floodplain analysis contexts. Their work for DoD involves delivering geospatial datasets that inform engineering designs and risk mitigation strategies for riverine systems, aligning with the Army Corps of Engineers’ mission priorities. This relationship suggests a pattern of engagement centered on environmental compliance, infrastructure protection, and post-event assessment support. The firm’s primary industry focus is on NAICS 541370—surveying and mapping services excluding geophysical work—which in practice means delivering aerial photogrammetric and laser scanning products for land and water resource management. They operate in the niche of applied geospatial science for public safety and environmental engineering, positioning themselves as a technical service provider for agencies requiring precise, actionable terrain data. Gahagan & Bryant Associates Inc. is a small, locally based firm headquartered in Santa Rosa, California, operating as a 2L entity with no federal certifications on record. Their market presence is geographically concentrated in California, with a specialized footprint in coastal and riverine infrastructure support, serving federal clients through targeted, high-quality geospatial deliverables.
