During the course of reconstructing the Wyoming State Training School, currently known as the Wyoming Life Resource Center, substantial demolition and regrading was required. This work produced varied materials that were temporarily stockpiled in a designated area, each with different material characteristics that would determine where and how they were to be disposed. Inberg Miller Engineers performed an aerial survey of the designated area in sufficient detail to estimate the original ground contours beneath the piles, and the topography of the piles. The image was then used in conjunction with ground observations to categorize the piles. The information was used to produce a map showing the layout of the piles and estimated volumes to help our client arrive at a cost for disposal with the contractor .
