Products and services

• Gyroscopic Mapping Services Gyroscopic pipeline and tunnel mapping using the Reduct system, providing accurate 3D geospatial data of subsurface utilities independent of depth and immune to electromagnetic interference. Suitable for utilities under buildings, railways, rivers, and roads.
• Line and Level Correlation Survey Services Subsurface sewer, pipeline, tunnel, and culvert surveys confirming horizontal alignment and vertical levels, using methods including 3D laser scanning, total station mapping, radio sonde, gyroscopic mapping, drone, and Sahara survey.
• Building Information Modelling (BIM) 3D digital modeling with assigned metadata for construction materials, costs, and services, creating a common baseline for site work throughout its lifetime, with deliverables in Revit, AECOsim, and point cloud formats.
• Aerial Drone Survey Services UAV-based acquisition of survey data for difficult-to-reach areas using photogrammetry and LiDAR point clouds, with deliverables including digital terrain models, topographical surveys, orthomosaic maps, and 3D models.
• Engineering Surveys High-accuracy surveys for detailed data and measurements supporting design, fabrication, and construction projects, including earthworks and volumetric calculations, and setting-out services.
• Confined Space Drone Services Specialized UAV inspection and survey services for restricted and hazardous environments, featuring 4K cameras, dust protection, optical stabilization, and 12K lumens adjustable lighting for condition surveys in sewers, manholes, tanks, and tunnels.
• Measured Building Surveys Detailed surveys of existing structures providing accurate floorplans, elevations, cross-sections, and CAD drawings or BIM models for architects, designers, and property management.
• Legal and General Surveying Services Chartered surveyor services for boundary matters including lease plans, boundary surveys, written reports, expert witness reports compliant with Civil Procedure Rules Part 35, and Land Registry compliant plans.
• PAS 128 Underground Utility Detection and Mapping Underground utility detection surveys following British Standards Institution PAS 128 specification, using ground penetrating radar, electromagnetic location tools, and the Reduct gyroscopic system to map utilities across quality levels D through A.
• Structural Monitoring Services Tailored monitoring schemes from annual settlement monitoring to hourly structural steel monitoring, using sub-millimetre digital levels, one-second accuracy total stations, crack gauges, tilt metres, and online portals with automatic alarm thresholds.
• Topographical Surveys Detailed land surveys of natural and manmade features in three dimensions, correlated to Ordnance Survey grid, with deliverables in 2D or 3D format including contours, spot heights, and elevations.
