Trusted for expertise, experience, integrity, and insight, Geofem delivers solutions that go beyond raw data to support resilient, safe, and cost-effective infrastructure management

"Their analysis of the InSAR data provided us with a network-wide understanding of historical ground movement across the Cape Town rail network, delivering spatial and temporal coverage that simply cannot be achieved through conventional inspection methods. This was particularly valuable given that our own physical verification was necessarily limited to targeted spot checks. The analysis quantified ground movement over multi-year time series and identified discrete areas of active deformation, distinguishing progressive settlement from seasonal variation and stable ground conditions.

The work delivered value on two fronts. First, it enabled us to target our limited site inspections and geotechnical investigations at locations where the data indicated genuine cause for concern, rather than relying on conventional sampling assumptions. Second, where field verification was undertaken, the observed conditions correlated well with the satellite-derived results, providing confidence in the technique as an effective screening tool for sections of the network that cannot be inspected physically at the same frequency. The analysis also identified several previously unflagged locations that have since been prioritised for further investigation.

We were particularly impressed by the quality of the analysis, the responsiveness of the team, and their technical expertise throughout the project. Their work demonstrated that satellite-based remote sensing is a powerful complement to traditional inspection methods, enabling earlier identification of potential issues, more targeted maintenance interventions, and better-informed, proactive asset management."

It was very useful to see how the displacement of the landslide had developed over time — not just how much movement had occurred, but also the direction of that movement. This gave us a clearer understanding of what was happening at the landslide and where further investigation or monitoring might be needed. Having this holistic long-term view gave us greater confidence in our understanding of the ground movement and provided a strong evidence base to support our risk assessment and decision-making.”

“Before Geofem's involvement, monitoring relied on sporadic site inspections and periodic level surveys. InSAR provides a greater density of time settlement data that helped to diagnose and confirm causes of settlement at lower cost than traditional survey.

Working with Geofem was a pleasure, made easier by their collaborative approach and responsiveness! They helped us understand satellite-derived data and how it connects with rigorous geotechnical interpretation in a way that made the findings clear and actionable. Their analysts and engineers were highly responsive throughout, helping us cut through uncertainty and better understand the likely settlement mechanisms at play. This ultimately reduced the need for further intrusive investigations and gave us the confidence to progress with a more targeted and effective remediation design."

“Their InSAR monitoring and detailed ground deformation analysis delivered valuable insight into the evolving behaviour of the landslide, significantly improving our understanding of site conditions and movement trends. The combination of technical expertise, clear communication, and genuine commitment to client support made Geofem a trusted partner and enabled more informed decision-making in a complex and changing environment.”

“The work was delivered quickly and with a high level of professionalism! We really appreciated the time the team took to clearly present their methodology and findings, ensuring we fully understood the results and their implications. Communication was seamless and their support felt consistently close, responsive, and engaged throughout the remote monitoring project.”

“Their professional support during meetings consistently demonstrated their strong technical expertise and reliability. Their tailored solutions have been instrumental in helping us and our client assess structural performance with confidence.”

​

The collaboration was smooth, communication was clear, and the results were delivered professionally and on schedule.

The post-delivery walkthrough was particularly valuable, helping us interpret the findings and ensuring we could confidently use the data provided going forward. Overall, the project was handled with great professionalism and discretion—it was truly money well spent. It was the first time we worked with Geofem, it will not be the last time.”

“The ability to remotely access reliable displacement data - including historical information dating back to project delivery - has proven especially beneficial. Integrating InSAR technology into our assessment process has significantly enhanced our confidence in monitoring and evaluating the structure’s long-term behaviour.”

Throughout the project, we received exceptional support from the Geofem team. Their assistance extended beyond the delivery of the InSAR analysis, guiding us through the interpretation of the results and supporting our decision-making on the next steps for the site.”

“InSAR would provide valuable insights in forensic engineering to assess causes of failures and damages to infrastructure and construction, and highly recommend Geofem in this regard.”
