Construction Supervision & Management

JEB provides construction supervision and management services for earthworks and civil infrastructure such as roads, railways, and airfields.

  • Quality Control in Situ & Laboratory
  • Project Management & Supervision
  • Design Authoring & Change Requests
  • Health, Safety, Environment (HSE) Supervision

Pavement Construction Supervision

We supervise and control pavement material application and quality using a multitude of tests and equipment such as the troxler, the sand cone test (verifies density and moisture content requirements), the plate bearing test, and others. Laboratory testing is performed on gathered soil, asphalt and concrete samples to ensure quality.

Equipment & Testing:

  • Troxler (nuclear density guage)
  • Sand Cone Test
  • Plate & Dial Gauge (bearing and deflection test)
  • Dynamic Cone Penetrometer (TRL and light model)
  • Pavement Coring
  • Laboratory Tests

Earthworks Supervision

JEB’s earthworks supervision services ensures filling and compaction meet the correct standards. An engineering team supervises the construction and assesses material quality.

Equipment & Testing:

  • Troxler (nuclear density guage)
  • Sand Cone Test
  • Plate & Dial Gauge (bearing and deflection test)
  • CBR
  • Proctor

Structural Assessment

JEB's structural engineers performs 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.

Equipment & Testing:

  • Sclerometer
  • Ferrometer
  • Magnetometer
  • Distometer
  • Ultra Sonic Testing

Aerial Surveys & Photogrammetry

The latest UAV technologies offer practical and cost-efficient ways to produce photogrammetry. UAVs are also used to shoot photography and video enabling a better understanding of a site location.

Once processed, the aerial imagery produces georeferenced orthomosaics with accurate geometry, dimensions, and object positioning (with accuracy up to 2cm). Aerial surveys are used to control and monitor site construction, perform volumetric calculations, support topographic surveys, and generate 3D models.
