Surveying

AB offers a comprehensive in-house surveying capability fully integrated with projects in site investigation, planning and design, using GPS, robotic and targetless surveying equipment. All surveys are processed using three-dimensional data. AB has many years of experience in producing three-dimensional Digital Terrain Models (DTMs).

Our skill areas include: topographic surveying and setting out;UAV (unmanned aerial vehicle) drone surveys;surveying geological and geotechnical features;setting out and surveying for engineered landfill cells;computation of volumes (including placed waste).  Survey Services Topographical surveying and setting out of quarry excavations, plant, tips and lagoons, stockpiles, borehole and piezometer locations and restoration levels.Setting out and surveying for engineered clay liners and caps in landfill cells and producing Construction Quality Assurance (CQA) drawings.UAV drones are used for large scale topographic surveys including quarries and earthworks. AB have also used UAV surveys for deformation monitoring of unsafe, inaccessible, obscurred quarry faces or landslides. UAV surveys enable the production of Digital Terrain Models (DTM) and Digital Surface Models (DSM) with removal of vegetation and are ideally suited for visual impact assessments, volumetrics of large scale earthmoving projects and catchment modelling or characterisation for hydrological studies.Surveying geological and geotechnical features such as faults, bedding planes, discontinuities, joint inclinations, weathering surfaces, and rock block sizes, base of overburden where exposed in quarry faces to assist in geotechnical analyses.Computation of volumes of mineral, overburden, total excavation, tips & stockpiles, placed waste volumes and available void space with modelled pre-settlement waste levels in landfill cells.
