Understand What's Underneath™
Trinity Subsurface Engineering uses a process known as Vacuum Excavation, also known as “Potholing” or “Daylighting” to safely obtain critical subsurface utility data such as:
Vacuum excavation has the capacity to collect all kinds of critical utility data for various construction and engineering activities. Utility data is important to eliminate conflicts with underground utilities when installing new utilities or structures, and when existing utilities need to be connected to.
Trinity Subsurface Engineering works with clients to collect the data that is most important to them, and the standard data we collect includes:
Underground utility data that is collected in a test hole using air vacuum excavation is documented on a Test Hole Data Sheet. This is a report that is completed in the field. Test hole locations are serialized and organized using a project number sequence.
Each test hole we excavate is documented with a data sheet, even if no utility is discovered. If additional utilities are discovered in a test hole location, additional test hole data sheets are completed for those utilities.
Utility locations and utility data may also be surveyed and added to existing civil drawings, or they can be sketched out using a satellite image. We also include a test hole matrix, which charts out a snapshot of the data for each test hole performed on one easy to read report.
