"It was a dark November evening; it was snowing, and our survey crew was more than 200-feet in the air atop the Utah State Capital Dome, freezing. David Eveans and Associates, Inc. (DEA) had been contracted to provide as-built drawings for the restoration of the historic capital dome. This task presented several challenges ranging from how to meet the accuracy requirements and tight schedule to how to collect and convey the data in a useful format. DEA responded by using a combination of laser scanning and conventional survey methods to provide highly accurate and easily usable data on a tight timeline."
