The Challenge
AsBuilt’s partner, Acensium, was engaged to provide laser scanning, 3D modeling, system design, and engineering support for the installation of an SJAE Water Box (WB) Vacuum Priming System at an operating power generation facility.
The project required integration of a new vacuum priming system within a constrained mechanical environment containing existing piping, structural steel, utilities, and critical plant equipment. Accurate field data was essential to:
- Verify existing conditions within the turbine and condenser support areas
- Identify spatial constraints and interferences
- Confirm tie-in locations and elevations
- Reduce installation risk in an active power plant
- Ensure constructability prior to fabrication
Legacy drawings did not reflect current field conditions, increasing the potential for clashes, rework, and schedule impacts. A high-accuracy digital capture was required to support engineering and seamless system integration.
The Solution
AsBuilt performed high-resolution terrestrial laser scanning (LiDAR) of the SJAE Water Box installation area, capturing all surrounding structural, mechanical, and utility components.
Field Data Capture
- Structural steel framing and supports
- Existing condenser and water box components
- Process piping and routing
- Electrical and auxiliary utilities
- Access clearances and maintenance zones
The scan data was registered and processed into a precise, colorized point cloud, providing a comprehensive digital representation of existing plant conditions.
3D Modeling & System Design
Using the processed scan data, AsBuilt developed accurate 3D as-built models (DWG format) to support engineering and system layout design.
The modeling enabled:
- Precise placement of the SJAE WB Vacuum Priming System
- Clash detection and interference resolution
- Validation of piping routing and connection points
- Structural support coordination
- Constructability review prior to field installation
By leveraging reality capture and 3D modeling, the team ensured the vacuum priming system could be integrated efficiently without disruption to plant operations.
Deliverables
- Raw laser scan data
- Post-processed, registered point cloud
- Photorealistic 3D visualization
- 3D as-built model (DWG format)
Results & Impact
The project provided engineering-grade as-built data to support accurate system design and integration within a live power generation facility. The use of laser scanning and 3D modeling reduced installation risk, minimized field modifications, and supported efficient project execution.
