Hanson Aggregates Quarries ALTA Surveys

McKim & Creed supplied ALTA/ACSM surveying services in connection with the acquisition of 16 sites for Hanson Aggregates East. Operating in nearly 400 locations in North America, Hanson produces aggregates, asphalt ready-mixed concrete, and cement. At any given time, 10 to 15 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.
