The objective for this project was to locate and map any concrete, utilities and unknown within the location for a new building site. This blind GPR survey covered approximately 5 acres of paved area which was a perfect fit for our tow behind 40 antenna unit. This 3D GPR survey was accomplished in one day with single passes and minimal overlap. All data collected was GPS referenced and combined with hi-res sUAS data to create a complete picture to incorporate in the design.
A little history on the site…Henry J. Kaiser had been building cargo ships for the U.S. Maritime Commission in the 1930s, and when orders for ships from the British government, already at war with Nazi Germany, allowed for growth, Kaiser established his first Richmond shipyard in December 1940. More than 747 vessels were built here in the four Richmond Kaiser Shipyards during World War II; a feat not equaled anywhere else in the world, before or since. All of Kaiser’s shipyards together produced 1,490 ships, which amounted to 27 percent of the total U.S. Maritime Commission construction.
