GPRS Helps Boats Safely Enter Harbor in Pago Pago, American Samoa

Ground Penetrating Radar Systems, Inc. (GPRS) was contacted by a well-known general contractor based in Hawaii, as well as many of the US territories, to locate the structural steel in four concrete pillars. These pillars were designed to hold a large tower that housed a light that when lined up with another lighted tower on the mountain side, would guide boats safely into the harbor and miss the shallow reef in Pago Pago, American Samoa.  These types of lights are able to be seen for miles out in the sea when in use.  Because of the light needing to line up with the light on the tower on the mountain, it was critical that all structural steel was located so the tower could be engineered properly, allowing them to get the placement within 3cm of the original light. The contractor was on an extremely tight schedule due to the sensitive nature of the tower and safety for all those traveling in and out of the harbor.  The scanning was completed on time for the tower to be constructed and in place in the time required by the large, international organization that requested the work.

Ground penetrating radar is a great tool to scan areas of post-tensioned cables, rebar, and conduits, including PVC pipes. Ground penetrating Radar can also be used for locating underground utilities such as water, gas, electrical, communication, sewer, underground storage tanks and associated piping, and other objects prior to digging or excavating.
