Topographic, Bathymetric & Underground Surveying

Topographic Surveying

Land Elevation & Contour Mapping

We produce highly detailed contour maps and elevation models that capture subtle terrain variations. These maps are essential for planning foundations, drainage, grading, and road alignments. By modeling slope gradients and terrain breaks, we help engineers and designers minimize risks and optimize layouts.

Topographic Mapping

Our surveys document all natural and man-made features—trees, buildings, utilities, roadways, fences, and drainage patterns—providing a complete site overview. This data forms the backbone of master planning, infrastructure design, and construction layouts.

Boundary & Property Line Surveys

Using high-precision GNSS and total stations, we define property limits with legal accuracy. These surveys support land acquisition, zoning approvals, and dispute resolution, ensuring compliance with UAE land laws and municipal requirements.

Digital Terrain Modeling (DTM)

By integrating survey data with advanced software, we generate 3D terrain models. These DTMs are used for volumetric analysis, cut-and-fill optimization, and design simulations, providing stakeholders with accurate visualization and measurable design data.

Bathymetric / Hydrographic Surveying

Single & Multibeam Echo Sounding

We deploy sonar systems to map seabed depths and underwater features with high accuracy. Single-beam sounding provides profiles along defined lines, while multibeam offers continuous 3D coverage of the seabed—critical for port works, dredging, marine structures, and reclamation projects.

Side-Scan Sonar & Seabed Classification

Side-scan sonar produces detailed images of the seabed surface, identifying hazards, wrecks, obstacles, and seabed textures. This data supports dredging operations, marine engineering, and environmental assessments by distinguishing between rock, sand, and silt.

Tide & Current Measurements

We conduct tide monitoring and current velocity surveys to understand hydrodynamic conditions. This information is vital for marine construction, coastal engineering, navigation safety, and sediment transport analysis.

Volume & Dredging Computations

Bathymetric data is processed to calculate material volumes for dredging, excavation, and reclamation. Our surveys help track progress, verify contractor works, and optimize dredging operations to ensure cost-effectiveness and compliance with project specifications.

Underground Utility & Subsurface Detection

Ground Penetrating Radar (GPR) Surveys

GPR is used to detect underground anomalies, including utilities, voids, and buried structures. This non-destructive technique provides real-time imaging, helping contractors avoid costly clashes with unknown subsurface conditions during excavation and foundation works.

Electromagnetic (EM) & Conductivity Surveys

EM detection complements GPR by identifying both metallic and non-metallic utilities at varying depths. These surveys help locate water, gas, sewer, and telecom lines, providing a complete subsurface utility map.

As-Built Utility Mapping

We prepare accurate “as-found” utility maps that integrate survey data into GIS and CAD systems. This ensures designers and contractors have a reliable record of existing utilities, preventing clashes and supporting future infrastructure upgrades.

Subsurface Obstacle & Void Detection

By combining GPR, EM, and conductivity tools, we identify underground obstructions such as boulders, cavities, or old foundations. Detecting these early reduces construction risks, improves safety, and avoids delays.

Integrated Survey Solutions

Combined Land–Marine–Utility Packages

We offer integrated survey solutions that combine topographic, bathymetric, and underground utility investigations in one mobilization. This reduces costs, eliminates duplication, and ensures all datasets are spatially consistent.

GIS & CAD Deliverables

Survey results are processed into GIS and CAD formats, providing engineers and planners with data that can be directly applied to design and construction workflows. Digital integration ensures efficient project execution and easy data sharing.

Construction & Design Support

Our survey teams work closely with engineers, contractors, and consultants throughout the project lifecycle. From pre-construction baseline surveys to as-built verification, we provide continuous support, ensuring projects meet design intent, authority requirements, and safety standards.
