Northwestern Mutual Life Building
The cornice of the Northwestern Mutual Life Building needed replacement. The project included providing accurate as-built drawings (to a demanding schedule) of the entire cornice about the perimeter. Collecting this data using traditional methods would have required weeks to complete, as well as the use of scaffolding or a swing stage.
Our 3-D laser scanning technology captured much of the visible data from the sidewalk, approximately 150 ft below, with an accuracy of 1/4 inch at 150ft. Once the data is compiled it was transformed into digital 2-D drawings.
Laser scanning documentation has the ability to provide additional data to vendors and designers as needed without having to return to the site. The scan is a snap shot in time of the existing conditions. In the future old scans and new can be compared and combined to track the change a building has undergone.
