Navy Pier is one of Chicago’s most popular tourist destinations, with retail, dining, and entertainment options woven throughout the 57-acre pier. For its 100^th anniversary, the pier embarked on a comprehensive development plan that included expanded green space, more event accommodations, and a taller Ferris wheel. Our team helped kick off this ambitious plan with ALTA and topographic survey services. The scope included the use of a global positioning system, Total Stations, 3D scanners, and direct levels to establish horizontal and vertical control and for the collection of 3D locations of all improvements. This work led the way to an impressive centennial for a beloved landmark.
