Subtech Survey Division can offer a total solution for on-shore, near-shore and transitional zone hydrographic & geophysical surveys and geotechnical investigations through global partnerships in the industry. We have comprehensive skills sets and experience encompassing land, marine, engineering, mining, LiDAR, geophysical, geotechnical and AUV projects. Subtech Survey Division has extensive experience in providing survey support for marine construction, port development, civil engineering, dredging, EIA projects, feasibility studies, verification & validation surveys, hazard identification and geophysical surveys.

Our in-field survey teams are supported by a range of high-end, world-class, industry standard survey equipment, dedicated shore management and a competent technical support network. The survey team has proven experience throughout the African continent and internationally. Our ongoing goal is to provide our clients with the highest level of professional integrity, data quality and scientific knowledge.

Subtech has established a strong hydrographic survey capability which includes high-resolution multibeam surveys, single-beam bathymetry, side-scan imaging, sub-bottom profiling and magnetometer surveys. Other supplementary and complementary oceanographic and environmental measurement services available include provision of water-level gauges, current meters, CTD and SVP probes. For transitional, intertidal and beach zones together with adjacent territories and engineered structures, Subtech can offer through its network of established partnerships with registered professional surveyors, LiDAR surveys, 3-D laser scanning, topographic, mining and engineering surveys.

Subtech has a Team of experienced technical personnel using top-class CAD and specialist software to produce professional presentations, reports, plots, plans, charts and fly-throughs of project sites and processed deliverables.
