📐 New Case Study — Elevator Shaft Laser Scanning at OSF SEMC Peru
Elevator shafts don't leave much room for error. When ADG needed existing conditions documentation at OSF SEMC Peru, TWG deployed the Leica RTC360 to laser scan the shaft and deliver an accurate Revit model the team could plan from with confidence.
No guesswork. Just accurate documentation from day one. 👇

Ever tried planning new piping or ductwork around systems that aren't properly documented? It's a gamble — and one that often catches up with you in the field.
For PIPCO's project at ICC PAC, we scanned the mechanical room, built a Revit model of all existing piping and ductwork, and gave their team a clear picture of what they were working with — before a single new system decision was made.
✅️ No guessing. No surprises. Just reliable existing conditions documentation to plan from.

Mechanical Room Laser Scanning for PIPCO | The Wassi Group Before PIPCO could plan new system tie-ins at ICC PAC, they needed to know exactly what was already there. TWG scanned the mechanical room and built a Revit model — giving the team a reliable picture of existing piping and ductwork before a single decision was made.
