New VA Medical Center; Phase 4
Las Vegas, NV; January 2009
Client: Clark Construction
Scope of Work:
• Direct Dimensions Inc. (DDI) digitally scanned nine rooms of the newly constructed VA Medical Center
located in Las Vegas, NV.
• Two DDI technicians, 4 days on site
• DDI utilized the acquired scan data to create as-built surface models suitable for importation into client’s
Navisworks software.
• Scan data accuracies of +/- 0.25” were achieved for this project
• Enhanced accuracy capabilities of +/- 0.020” are now possible
