Transforming infrastructure through smarter information

The Chartered Institution of Civil Engineering Surveyors (ICES) journal Geospatial Engineering 2018-2019 has published an article highlighting the work of Sakthy Selvakumaran.


Geospatial Engineering is an annual publication that showcases developments in geospatial engineering. The article titled ‘Integrating InSAR with digital engineering models and conventional surveying methods’ discusses how satellite radar data can monitor millimetre-scale displacements to help predict weaknesses in built infrastructure assets from space. Citing a number of current live projects featuring InSAR techniques, Sakthy, whose research is also presented in the 2018 CSIC Annual Review, considers the use of digital models to derive value from that data in the future.

Sakthy, a PhD researcher in the Department of Engineering at the University of Cambridge, with project funding from EPSRC (UK), iCase sponsorship from the National Physical Laboratory and additional funding from Laing O’Rourke, CSIC, the Satellite Applications Catapult, and the Centre for Digital Built Britain (CDDB), writes about the benefits of integrating InSAR datasets with digital engineering models and conventional surveying methods.

“Combining a range of monitoring technologies enables assessment of new generation techniques and comparison with more traditional monitoring. The reliability of InSAR applications can be assessed for future use and identify opportunities to embed new practice into current methods. A key potential benefit of this process is to better understand the performance of our structures; robust and reliable data can leverage whole-life value of an asset or portfolio of assets by informing more efficient asset management.”
