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.

Aerial Surveys

Drone surveying is the process of surveying an area with an unmanned aerial vehicle and downward-facing sensors to obtain geospatial data. We offer two remote sensing methods, photogrammetry and lidar. Surveys with drones are an excellent asset in the fields of engineering and construction. These devices are capable of rapidly producing highly accurate point clouds, orthophotography, and digital models of land areas.

Our data collection services aid in land development, construction projects, archaeology, forest and agriculture management, and so much more. Learn more about our remote sensing services.

Structural Assessment and Analysis

We perform structural assessments to check the structural integrity of buildings and their components (columns, beams, etc.). An assessment is made to evaluate the potential of a structures current and future use, often for modifications or renovations.

Structural analysis is the process of calculating and determining the effects of loads and internal forces on a structure. This analysis is particularly important to understand the load paths and the impacts loads have. Structural assessments and analysis ensure that a structure is safe for use under the estimated loads it is expected to withstand.

Laboratory Testing

We provide laboratory testing for various materials such as soils, rocks, water, concrete, rebar, and more to determine material properties. The results of laboratory tests are crucial for analysis and design. During an investigation, we log dates, times, locations, and other information concerning each material sample gathered. Then, a laboratory testing program is developed and specific laboratory tests are assigned to each sample.
