b

uilding information modelling (BIM) standards and construction best practice stress the need for timely, accurate mapping updates to ensure efficient monitoring

of progress on site. These updates are traditionally provided by established survey technologies such as total station, laser scanner or, more recently,

photogrammetry, using imagery captured by remotely piloted airborne

“

systems (RPAS, aka drones). These techniques provide high-accuracy

surveys, but they require personnel or hardware on site (or in the sky

overhead) and operations can be restricted in busy, isolated, hazardous or

sensitive areas. Satellite remote sensing offers an alternative, rapid, non-

contact approach that is exportable and repeatable for any site worldwide, and has been demonstrated recently in developing countries via the World

Bank. In this SCSI-funded study, we developed and tested an automated approach using a Dublin coastal site as a test case, demonstrating the

suitability of recent advances in satellite technology for a 3D and 4D BIM process in Ireland.
