Topographical surveys provide the client with a high scale map of the ground and existing physical features within a defined survey boundary. This information is typically used by planners, architects, and engineers throughout the whole life cycle of a project. Ranging from large urban developments to small private gardens, brownfield or greenfield sites, Gwalia Surveyors have accumulated a wealth of experience over our 35 years of trading.
Specification can be tailored to suit client requirements ensuring the highest level of service is maintained within challenging or demanding site environments.
We use the latest surveying equipment and technology such as robotic total stations, GPS systems, laser scanners, and UAV's to accurately record on-site information/detail in the most cost-effective and suitable manner. The captured data is then processed to map the on-site features which include trees, terrain, levels, structures, roads to name but a few. Regular, rigorous redundancy and computational checks are undertaken at all stages on every project.
Deliverables of 2D and 3D survey drawings can be supplied in a range of digital formats as specified by the client.

Concrete & Structural Scanning
Concrete scanning is a non-destructive method of detecting, locating, and mapping concealed objects within solid surfaces. This solution can identify steel reinforcement, cables, conduits, and post tensioning without the need for invasive investigations such as breaking the concrete with trial holes etc. Concrete scanning is particularly beneficial when drilling or coring into concrete, walls, or structures giving the client prior knowledge of elements to avoid.
We can deploy the latest handheld scanners, GPR and detectors, to conduct this service. We can offer real time on site mark-up or post processed results and reporting.
Drone Surveys - Visualisation & Verification
Drones or Unmanned Aerial Vehicles (UAVs) are fast becoming a reliable, cost-effective method of data capture for use in many applications. The rapid development of this technology now makes previously hard to reach environments accessible. Armed with high precision cameras and sensors, drones can record and store data remotely from a position of safety. Together with advances in software development, drones can now be applied to a number of survey based, visulalisation, and verification activities of the built environment.
High quality imagery captured by drones can be processed using photogrammetry software to produce high quality point clouds. This data can then be used to manufacture an array of deliverables such as 2D drawings and 3D models, similar to the laser scanning process.
