SqueeSAR™ is an all-stage monitoring tool for engineering projects: from the design to the construction and operation phases.

SqueeSAR™ can provide an important input to all stages of any construction project by identifying unstable areas affected by ground movements and reconstructing their displacement history. It also gives a unique support in surveying underground constructions.

Our SqueeSAR™ analyses are used to:

  • determine existing ground movements during site selection processes,
  • assess impacts of engineering activities and complement conventional monitoring,
  • assess the stability of key infrastructure, multiple assets or distributed networks.

No ground-based instrumentation is required. By identifying targets already present on the ground, SqueeSAR™ detects a significantly higher density of measurement points than any traditional ground-based surveys (e.g. GPS, leveling, total stations).

We are member of the International Tunnelling and Underground Association - ITA-AITES.

Design

SqueeSAR™ gives a unique support in reconstructing past ground motion patterns, which could potentially impact civil constructions.

site characterization

Using a historical archive of satellite imagery, SqueeSAR™ can identify unstable areas and reconstruct their displacement to assist in the planning of new sites, routes, network extensions and duplications for e.g., giving a unique insight for key development projects.

For linear structures such as roads and railways, monitoring with satellite data minimizes survey time and cost compared to traditional techniques.

Construction

SqueeSAR™ detects millimitre-scale ground settlement occurring during construction works.

ground settlement

By mapping the temporal evolution of ground displacement occurring during construction, engineers can better understand the relationship between activities and the onset of any related settlement. SqueeSAR™ offers thousands of measurement points over large areas, at a fraction of the cost of traditional monitoring. It also increases displacement information beyond excavation surroundings, to determine the extent of any deformaion occuring within a wider area.
SqueeSAR™ also solves uncertainty: it eventually verifies that the predicted deformation corresponds to reality.

Operation

Regular monitoring of post-construction displacement with SqueeSAR™ can identify structural weaknesses.

assess stability
control impact on assets

Identifying movements that could indicate a structural weakness helps engineers to determine if remedial actions should be taken. Moreover, satellite monitoring with SqueeSAR™ provides deformation maps for assessing areas at risk that could potentially affect structures.
