Borrow Pit As-Builts from Sonar and HD LiDAR Fusion

The Borrow Pits

Water storage pits are built to support operations in many industries including oil and gas and agricultural operations. Reliable sources of collected runoff water are critical to many industries and collection points must be monitored and maintained like any other asset. Ranging in size from 50 meters to several hundred on a side and not necessarily having good foot or vehicle access, these pits can be a nuisance to survey with conventional methods.

Regulations

Stricter new provincial regulations mean that regulatory agencies are now ensuring that proper design parameters were used in the construction of existing pits. It is also possible that companies may acquire or use pits for which they do not have engineering information, as they may not have been involved in the building and design phase.

The Data

Since it is impractical to drain these pits to obtain accurate total depth, slope and total capacities, the use of Unmanned Surface Vehicles (USVs) equipped with Sonar in combination with High Density LiDAR has allowed Skytech to gather these parameters and provide accurate as-builts without the need to empty the storage pits.

The Result

The image above is an example of the High Density aerial LiDAR gathered from one of these pits. This data is then summarized in a short PDF deliverable displaying all critical pit information which has been extracted. Our clients have found this deliverable and the meshing of Sonar and LiDAR capabilities to be extremely useful to accurately show their compliance to the new regulations.
