The August 2012 issue of Professional Surveyor magazine cover story describes the workflows and benefits of using Leica HDS laser scanners and Cyclone software to aid in the accurate and timely construction of the new East London Olympic Stadium - the centerpiece venue of the 2012 summer games. The 80,000 seat stadium is designed and constructed so that it can be readily modified after the games to a smaller capacity venue for other events.

| Construction of the stadium involved 224 structural components (up to 3'6" in diameter) weighing over 2,400 tons, covering an area 1033' x 840', and up to 197' high. Critical to construction success was fast, accurate dimensional control of prefabricated elements with their mating surfaces and holes - all checked during construction to enable modifications on-the-fly as needed. Long time Leica HDS user ABA Surveying carried out the scanning and modeling work. The benefits of scanning were fast, remote, accurate, and complete data capture that enabled accurate 3D models to be created of each structure and mating scenario. Scanning provided an easy QC means for comparing design with actual construction, doing "virtual fit-up analysis", and it also avoided the need for unplanned return visits to capture additional information. |
