The Challenge
A power plant was preparing to replace two condenser vacuum pump systems. The scope included removal of the existing vacuum skids, associated piping, and the concrete pads supporting the previous installations.
Given the tight integration of the vacuum systems with surrounding equipment and structures, accurate documentation of existing conditions was required to support demolition planning, foundation removal, and installation of the new systems.
The Solution
AsBuilt provided 3D laser scanning of each condenser vacuum pump area to capture precise as-built conditions of the skids, piping, concrete pads, and surrounding infrastructure.
The scan data was processed into detailed 3D models, giving engineers and contractors a reliable digital representation of each unit. This information supported planning for removal activities and ensured the new vacuum pump systems could be installed with confidence and minimal field adjustments.
Key Outcomes
- Accurate Existing Conditions
Scan-based models replaced uncertainty around legacy installations. - Improved Removal Planning
Contractors used the models to plan demolition and skid removal safely and efficiently. - Confident Installation of New Equipment
Verified geometry supported proper placement of new vacuum systems and foundations. - Reduced Field Risk
Early visibility into constraints minimized surprises during execution.
Deliverables
- Raw Scan Data
- Registered 3D Point Cloud
- 3D As-Built Models
Why It Matters
Equipment replacements in operating power plants demand precision. By capturing accurate as-built conditions before removal and installation, AsBuilt reduced risk, improved coordination, and supported a smoother transition to new condenser vacuum systems.
