Our drone-based terrain mapping service employs unmanned aerial vehicles (UAVs) equipped with cameras and sensors to rapidly survey the land from above. This approach captures high-resolution data across extensive areas in a fraction of the time of traditional ground surveys, with minimal disturbance to the site. It is especially valuable for surveying difficult or hazardous terrain (such as steep and vegetated slopes) where on-foot access is challenging. The result is a detailed digital model of the landscape – including elevation models and aerial imagery – that aids in planning, design, and monitoring for large projects.
  • Fast, efficient coverage of large or inaccessible areas, reducing field time and costs
  • Improves safety by surveying hazardous or rough terrain without putting personnel at risk
  • Generates high-resolution orthophotos and 3D terrain models for accurate site analysis
  • Ideal for expansive sites like infrastructure corridors, mines, or landfills where conventional surveys are too slow
Our UAV photogrammetry surveys use drone-mounted cameras to capture numerous overlapping images of a site, which are then processed into precise maps and 3D models. This technique provides a high level of detail, allowing us to produce accurate orthomosaic imagery, point clouds, and terrain models that reflect real-world coordinates. It is an excellent solution for complex sites or structures, enabling measurements of distances, areas, and volumes directly from the digital model. Clients benefit from the speed and accuracy of photogrammetry, obtaining survey-grade results for large areas or hard-to-reach features without extensive ground work.
  • High-resolution orthomosaic maps offering true-to-scale aerial views of the site
  • Dense 3D point clouds and digital surface models capturing fine details of terrain and structures
  • Allows precise distance, area, and volume calculations for design and earthworks planning
  • Speeds up data collection for expansive or inaccessible sites while maintaining survey-grade accuracy
Our aerial imagery service provides up-to-date, high-definition overhead photographs of the site for a clear overall perspective. Using drone or aircraft-based cameras, we capture visual data that helps stakeholders quickly grasp site conditions, layout, and progress. Aerial imagery is often used to complement surveys, offering context for planning proposals, environmental assessments, or marketing materials. It enables developers and planners to spot features or issues not obvious from the ground, and to track changes over time. Crystal-clear aerial photos or orthomosaics that provide a bird’s-eye view of the entire site
  • Ideal for monitoring construction progress, capturing before-and-after comparisons, and stakeholder presentations
  • Enhances planning and design by overlaying imagery with survey data or cross-sectional plans for better context
  • Gives clients and regulators confidence with visual evidence of site conditions, without lengthy site inspections

Our as-built surveys precisely document the final state of a project or site features once construction is complete. Our surveyors measure the exact locations, elevations, and dimensions of built structures, utilities, and site improvements, creating a record of what was actually constructed versus what was planned. This service is crucial for project sign-off and compliance, confirming that the works meet design specifications and regulatory requirements or highlighting any deviations. An as-built survey provides peace of mind to developers and engineers, and delivers a reliable reference for future maintenance, modifications, or legal documentation.

  • Captures the exact as-constructed positions and elevations of buildings, roads, utilities, and other improvements
  • Verifies compliance with design plans and construction tolerances, identifying any on-site deviations
  • Essential for obtaining final approvals, by providing trustworthy survey records
  • Gives owners and operators a complete set of updated drawings for asset management and future project planning
Our site layout surveys involve detailed on-site measurement and recording of existing site features, levels, utilities, and drainage runs. Data gathered on-site is translated into clear and precise layout plans, specifically tailored for permitting and environmental management systems. Our flexible approach means site plans can be continuously updated as site conditions evolve, ensuring regulatory compliance, operational efficiency, and effective site management over the life of your project. Our plans clearly represent all site infrastructure, enabling smooth permitting processes and improved project planning.

  • Easily updatable plans, supporting evolving site management requirements
  • Clear documentation for effective site operational and compliance reporting
Our material & earthworks quantity surveys involve measuring and calculating the volumes of soil, rock, or other materials excavated, filled, or stockpiled on a site. Using techniques like ground surveying and drone photogrammetry, we generate precise volume calculations to support project needs. This service is vital for managing earthworks in construction, mining, or landfill operations – it ensures that everyone knows exactly how much material has been moved or remains in place. With accurate quantity data, project managers can verify contractor claims, plan haulage requirements, track landfill capacity, and keep projects on budget and in compliance with regulations.
  • Precise volume calculations for cut, fill, and stockpile materials using advanced surveying techniques
  • Helps contractors and clients track earthmoving progress and avoid discrepancies in quantity estimates
  • Supports informed decision-making for resource allocation, haulage planning, and site logistics
  • Provides necessary data for environmental compliance (e.g., landfill capacity reporting) and financial accountability
Our cut and fill analysis provides a comprehensive view of your earthworks balance by modelling the current terrain against the planned finished grade. By precisely calculating where materials must be excavated or filled, we help optimise your site’s material use. To further enhance accuracy and support the construction phase, we offer real-time staking out, clearly marking target elevations on-site. This “live” staking approach helps site teams work efficiently and accurately, minimizing waste and the need to import or export soil. By properly balancing earthworks, projects can significantly reduce earthwork costs, time, and environmental impact while ensuring the final design levels are met.
  • Detailed cut-fill mapping and accurate material volume calculations
  • "Live" staking out to guide site teams with clear elevation markers
