Paul Fassam Geomatics Ltd has been pioneering drone technology around airfields for some time now. UAV pavement inspections are our latest offering which promise to revolutionize this historically slow practice. Using either a multi-rotor or fixed wing aircraft, a low-level grid is flown over the hardened areas.
High-resolution photography captures the surface to a resolution in excess of 3mm. These photos are then rectified to produce a flat image of the entire survey area. The image allows pavement inspectors to safely measure and mark features in the safety of their office. Overal this method greatly improves the deliverable whilst also saving time on site. We provide a full suite of services to provide greater confidence to clients in underground utility detection, maintenance, and replacement.
PAS provides a robust methodology for delivering utility surveys in the UK. It focuses on levels of accuracy — referred to as Survey Category Types — that you can specify when requiring a PAS compliant underground utility survey. Underground utility plotted from utility record data only, but with site reconnaissance to match utility record with physical utility street furniture as a best fit. Utility verified and positioned by physical identification. This may be by strategically positioned vacuum excavation, hand dug trail pitting or by visual inspection within a utility chamber.
