CITY AUDITORIUM UPDATE
By Chris Wineman, Principal, Semple Brown
Up to now, the design team for the renovation of the City Auditorium has relied on review of historic drawings and in-person evaluations of the building to plan for future improvements. This month, we’re excited to share a new level of analysis and tools that will benefit both the design team and the construction team.
Our partners at Saunders Norwood Construction have scanned the building using laser technology (LIDAR – Light detection and Ranging), and from those scans have generated a “point cloud” that represents the structure of the existing building in three dimensions which is accurate to 1/8”. On April 6, Nick McCombie, who is a Survey Manager for Saunders Norwood, brought his scanning equipment to the City Auditorium, and over a period of about 6 hours, scanned the exterior and interior of the building from multiple locations.

The Integrated Technologies group (ITG) at Saunders then collated those individual scans to match them up, creating a 3D model of the building that is composed of those many individual points.
Matthew Hamann, the Integrated Services Manager for Saunders Norwood met with Semple Brown’s architectural team to show us the information contained in the model, and how to match it up with our in-progress design documents. With this information available to us, we can
• Compare that 3D point cloud data with our own 3D digital model to confirm critical dimensions
• Evaluate the accuracy of the historic drawings

• Capture all areas that were visible at the time of the scan including areas that are difficult and dangerous to reach with typical field verification methods.
As the Saunders Norwood team begins to plan for construction, they will be able to use the model to plan how they will bring materials into the building, fit new floors and walls into the building and allow enough space for ductwork and other equipment, and reference back to the point cloud for any existing condition questions as the design develops.
