Topographical Survey

General

We provide topographical survey service that will be carried out to establish the topographic conditions as basis for the planning and execution of building & infrastructure projects. With respect to the project requirements gbc - geotechnical engineering provides: 
  • Topographic land survey 
  • Hydrographic survey 

Topographic land survey 

gbc - geotechnical engineering provide the land survey with the following detailed services:
  • Mapping the contours of ground and existing features above or below the earth's surface (i.e. trees, buildings, streets, walkways, manholes, utility poles, retaining walls, etc.).  
  • Perimeter boundary lines and the lines of easements on or crossing the property 
  • Bench marks / control points will be established with respect to the national grid coordinates (chart datum)
  • Based on the survey results and field observation, a digital elevation model (DEM) of the area surveyed will be provided
  • Mapping will be provided based on the survey results and a survey map will be prepared in scale 1:500 (may vary as per contract conditions) using AutoCAD Civil 3D software

Hydrographic Survey 

gbc - geotechnical engineering provide the hydrographic survey with the following detailed services:
  • Water depth measurement of ocean, rivers and lakes for construction and engineering design
  • We can offer hydrographic survey from cost efficient single beam profiling to full coverage swath bathymetry using modern multibeam sonars including mapping and visualization
