Some of the Utility Information Recorded:
|• Depth to Top of Utility||• Pre Design|
|• Depth to Bottom of Utility||• Exposing Utility Conflicts|
|• Utility Type and Size||• Soil Borings|
|• Road Surface Thickness||• Directional Boring Test Pits|
We utilize a revolutionary technology called Air/Vacuum Excavation to locate, expose and map facilities. Air/Vacuum technology is employed to quickly and efficiently move soil from the test hole to holding tank on the truck.
Location & Surface Opening: Utilities are designated and marked using highly specialized electromagnetic and radio frequency instruments. Then, a 12 inch square opening is made just above the utility area.
Exposing (daylighting): The buried utility is uncovered via air vacuum high pressure "Airlance" which loosens the soil around the utility - without damaging buried facilities.
Soil Extraction (Air/Vacuum): A powerful air/vacuum pulls the soil out of the exposed area and deposits the material in a large mobile tank.
Depth Measurement & Mapping: With the utilities exposed, depth can be verified, and mapping/surveying activities can be accurately performed. Air/vacuum methods help achieve desired results, especially critical with the increasing emphasis on trenchless technology-directional bore construction.
Result: Utilizing Air/Vacuum technology, the entire process takes approximately 45 minutes per hole, is completely safe and environmentally compliant. The only evidence of APS presence is a 144 square inch (or as in this case, round) patch.
