Services
Hydrographic Survey
Our hydrographic survey service uses acoustic sonar and high-resolution GPS to collect precise depth and bottom-feature data. This information supports safe navigation, dredging planning, and infrastructure design for marine terminals. Deliverables include detailed charts and reports that meet industry standards for accuracy and reliability.
Geophysical Survey
Our geophysical survey identifies subsurface hazards such as unexploded ordnance, sediment layers, and foundation anomalies. Using specialized equipment, we collect data that aids in site safety and design decisions for marine construction. Results help clients avoid costly delays and ensure compliance with environmental and safety regulations.
Geotechnical Investigation
Our geotechnical investigation examines soil, sediment, and seabed conditions to assess bearing capacity and stability. We collect samples through borings and cone penetrometer tests for laboratory analysis. The findings inform foundation design, dredging limits, and risk mitigation for marine structures.
Dive Inspection
Our certified hard-hat divers conduct thorough underwater inspections of pilings, hulls, and submerged structures. Using video and tactile methods, we document corrosion, damage, and biological growth. We also assess scour around foundations and verify compliance with safety standards, providing actionable recommendations for maintenance, repair, or replacement decisions.
Environmental Permitting
Our environmental permitting specialists guide clients through complex local, state, and federal requirements for dredging and waterfront projects. We prepare applications, coordinate with agencies, and monitor compliance throughout project execution. This support reduces delays and ensures projects meet all regulatory obligations.
