Survey Services

JEB’s surveyors use a variety of techniques to determine, measure, and represent land (above and below water) and structures. We use this information to interpret all the natural and artificial features before planning and designing infrastructure. It’s also used to control the geometry of works completed by contractors.

Topographic Surveys

Topographic surveys are at the heart of all our activities. These surveys locate all surface features of a property to create a 3D map depicting all natural and man-made features. Our clients use topographic surveys for a wide variety of reasons. Some common uses are the reaffirmation of property boundaries, determining if a property is suitable for a construction project, and planning the design of civil works (roads, bridges, utilities, drainage, etc.).

Bathymetric Surveys

Hydrographic and bathymetric surveys allow us to accurately map underwater features and understand the properties of a body of water. Bathymetric surveys are commonly used before planning marine constructions such as bridges, wharfs, underwater earthworks, etc.

  • Single Beam Echo-Sounder 200kHz
  • Adapted Survey Vessel
  • Hydromagic Software

Drone Photogrammetric Surveys

Photogrammetric surveying is a practical and cost-efficient way to survey large or dangerous areas like quarries or for excavation work. We create topographic maps using aerial imagery and a Differential Global Positioning System (DGPS). While the accuracy is less than traditional surveying, photogrammetric surveying is considered to be suitable for volumetric calculations for stockpiles and excavations. This type of surveying requires specific skills and techniques to obtain reliable data.
