Land & Engineering Surveying

GCI undertakes accurate and reliable topographic & hydrographic mapping, terrain data and underwater bed models for detailed engineering design and volumetric calculations.

Topographic mapping for engineering design & construction	Earthworks surveys & volume estimates for land development	Site/project boundary, legal, lease & ROW surveys
Golf course surveys, pre- & post construction for volume quantities & claims	Stockpiles, waste, & overburden surveys for mining & extraction	As-built surveys & drawings for land infrastructure & structures
Hydrographic (bathymetric) surveying and mapping	Erosion/accretion surveys for coastal & riparian developments	Sub-surface mapping with Ground Penetrating Radar (GPR) & SWAS
Control network design, establishment & monitoring	Exploration grids, borehole surveys & mine surveys	UAV (drone) mapping (topographic and feature) and modelling for large and/or difficult sites
3D digital terrain, elevation & surface modelling (DTM, DSM, DEM)	As-built surveys for Building Information Management (BIM) modelling	Route, transmission & corridor mapping


*The Bluffs Championship Golf Course – Ho Tram, Vietnam*GCI survey crews worked extensively on this premium gold destination, from initial topographic and control surveys to earthworks and volumes surveys to final golf and infrastructure as-builts surveys and drawings. GCI was engaged by the owner/developer and golf course contractor at various stages of the project.	*Ninh Thuan Nuclear Power Project II -Ninh Thuan Province, Vietnam*GCI provided aerial photography and topographic mapping at 1:5000 and 1:100 scales for the Feasibility Study of Vietnam’s first modern nuclear power projects. Over 200 km² was flown and mapped for AAS of Japan, under JICA funding.	*RoyalToll Railway -Phnom Penh to Sihanoukville, Cambodia*Novare Design from New Zealand engaged GCI for the topographic and utility feature mapping of over 30 level rail crossings on the Cambodian Railway Southern Line.
