George J. Igel & Co., Inc. builds electronic models with in house staff for use in its GPS grading fleet. This technology, combined with our trained staff, provides fast and accurate grading for hundreds of acres per year. We use GPS guided scrapers, dozers, compactors and even hydraulic excavators to give the total project defined detail. Our gradecheckers can pinpoint future features with GPS rover rods without using stakes, meaning faster, more environmentally friendly site development for our customers.
