Continuous monitoring of a cultural heritage site

Client: Metro C S.c.p.A., IMG S.r.l.
Period: July 2009 - September 2010
Location: Rome (Italy)
Technologies: Terrestrial RAR Interferometry


Continuous monitoring of the deformational behaviour of a cultural heritage site before the start of tunneling excavation works.


TInRAR (Terrestrial RAR Interferometry) permanent monitoring platform was installed on a tower specifically designed and realized for monitoring purposes, according to architectonic specifications. The device was equipped with a weather station and set up for 24/7 continuous data collection, with a 30s sampling frequency. Data collected were automatically transferred on a remote server for the periodical control through a specifically developed analysis software. A detailed topographical survey was also carried out to reconstruct the main architectural elements of the monumental heritage.


The overall stability condition of the structure was assessed by TInRAR monitoring. No weak sectors of the structures were identified in any weather condition and data were also validated through the comparison with data collected by other monitoring sensors.
