McKim & Creed supplied ALTA surveys in connection with the acquisition of 16 sites for Hanson Aggregates East. Hanson is one of the largest producers of crushed stone, sand and gravel in the U.S.
At any given time, 10 to 15 McKim & Creed survey personnel worked onsite, while four to five designers processed the data in-house. To expedite data collection, survey crews used RTK-GPS (Real-time Kinematic Global Positioning System) extensively. To fulfill Hanson’s request for contour data on three of the sites, McKim & Creed incorporated aerial photogrammetry into the land surveys. Within three months, the preliminary surveys were completed and submitted.
