Settlement monitoring of a new building constructed on variable and compressible soil was needed but the site was highly restricted and access for settlement measurements was denied.

Corner reflectors were designed and installed during construction in order to measure building and surrounding ground displacement at specific points by InSAR with satelllite data analysis without needing to visit the site.

Highlights

• Building and ground settlement monitoring was needed on a site with severely restricted access.

• Corner reflectors were designed and installed at specific locations during construction. 

• Remote settlement monitoring of the building and surrounding ground by InSAR is ongoing.
