$3 Billion Water Treatment Plant Expansion Required Accurate As-Builts and 3D Revit Model

• The facility was planning upgrades to ensure that the intake, transmission, treatment, and wastewater systems worked as efficiently and effectively as possible.
• A facility expansion was being designed to increase the treatment capacity from 300 to 600 million gallons of water a day.
• Outdated as-built drawings increased the risk of design conflicts and costly rework.
• The client required laser scanning and a 3D model to uncover discrepancies and ensure accuracy.
• The point cloud needed to be aligned to existing survey control for consistency across disciplines.

‍

• GPRS 3D laser scanned the water treatment plants with a Leica P-series laser scanner, capturing precise as-built data of the densely populated facilities.
• A 3D point cloud and 360° LDR panoramic images were captured at each scan location in less than 20 seconds.
• The point cloud was aligned to a known coordinate system, providing consistent and accurate survey control.
• GPRS delivered separate Revit models for each discipline: architectural, structural, process mechanical, HVAC, plumbing, fire protection, and electrical.

‍

• This $3 billion expansion project required reliable data to plan system upgrades at this scale.
• Deliverables were uploaded to Cintoo, a cloud-based platform enabling rapid delivery and web browser access to scan data and models.
• The engineering team could share and collaborate in real time, reducing delays and miscommunication.
• The project ensured a safe, reliable water supply for Nevada residents and businesses, supporting long-term growth in the Las Vegas region.
