Our Core Geospatial and Geophysical Services Include

Geophysical Subsurface Imaging: Utilising Ground Penetrating Radar (GPR), Electrical Resistivity Tomography (ERT), and seismic refraction to map bedrock depth, identify soil heterogeneity and locate buried utilities or archaeological anomalies without excavation.
High-Precision Geodetic Surveys: Establishing primary control networks using Global Navigation Satellite Systems (GNSS) and Real-Time Kinematic (RTK) positioning to ensure millimetre-level accuracy across vast project sites.
Hydrographic Surveying: For coastal developments and reservoir management, we employ multibeam echosounders and sub-bottom profilers to map underwater topography and sediment layers.

These capabilities are essential for the safe routing of oil and gas pipelines and the stable foundation of large-scale civil structures, ensuring that our Specialised Engineering teams work with a complete understanding of the terrain.

Next-Generation Aerial and As-Built Surveying

To meet the scale of regional giga-projects, we have moved beyond traditional land surveying into rapid, large-scale aerial acquisition. We utilise Unmanned Aerial Vehicles (UAVs) and aircraft equipped with advanced sensors to capture the ‘as-is’ state of the world with unprecedented speed.

Our Aerial and as-built Capabilities Include

Light Detection and Ranging (LiDAR): Deploying aerial LiDAR to generate high-density 3D point clouds, capable of penetrating vegetation and accurately mapping complex topography and existing infrastructure.
Photogrammetry and Orthomosaics: Producing high-resolution, geo-rectified maps and 3D models that provide a visual and measurable snapshot of project progress.
As-Built Verification: Using 3D laser scanners for High Definition Surveying (HDS) to document completed structures. By comparing these as-built models against the original BIM designs, we identify deviations in real-time, allowing for immediate corrective action during the construction phase.

Rich, Flexible Data for Modelling and Analysis

Data collection is only as valuable as the insights it generates. We deliver data in flexible, industry-standard formats that integrate directly into decision-making engines. We focus on data fluidity, ensuring that a survey conducted today can be used for engineering analysis tomorrow and facility management for the next twenty years and more.

We Provide

BIM and GIS Integration: Seamlessly merging high-precision site data with GIS and BIM allows stakeholders to visualise spatial relationships, environmental impacts and logistical constraints in a single unified interface.
Volumetric and Change Analysis: Utilising sequential survey data to provide precise calculations of earthworks, material stockpiles and construction progress.
Environmental and Geotechnical Reporting: Transforming raw sensor data into comprehensive reports that inform environmental impact assessments and structural design parameters.

Integrated Data Flow and Security

A unique differentiator of our business model is the integration of data collection with our Digital Infrastructure pillar (see page 6). In an era where geospatial data is a strategic national asset, security and seamless movement of this information are paramount.

Our Integrated Data Framework Ensures

Secure Data Transmission: Leveraging our fibre optic networks and encrypted satellite links to move massive datasets from remote field sites to centralised command centres without risk of interception.
Live Sensor Feeds: Integrating IoT sensors into a real-time data flow. This allows for the continuous monitoring of infrastructure health, such as bridge vibration, pipeline pressure or reservoir levels.
Cyber-Physical Protection: Applying our full-scope cyber security protocols to the data collection chain. We protect the integrity of the data from the point of capture (the sensor or drone) to the point of analysis, ensuring that the digital truth of the infrastructure remains untampered.
