Physical Trial Holes are dug every day to understand buried infrastructure locations and type prior to (capital) works design and commencement of construction activities.
By using a digital handheld system to enable all excavation works to be recorded and stored in the Cloud. At the first stage of the excavation exposing the exisitng asset, all necessary information is recorded for creating the VTH –
1. Utility type, size and material
2. Ground conditions - soil, rock, clay
3. Third party utilities - Gas, Electric , BT, Cable,Water
4. Locations - Carriageway, Footway, Verge, Field
By creating the Virtual Trial Hole from the asset exposure information, it will save on traditional physical trial holes on our highway network.
