The Challenge
A hydroelectric dam operator required accurate as-built documentation of the intake system to support upcoming equipment upgrades. The facility did not have existing as-built drawings, and the intake equipment was located on steep, difficult terrain, making traditional field measurement unsafe, slow, and prone to error. Accurate as-is data was critical to avoid design risk and retrofit issues.
The Solution
AsBuilt was contracted to capture the true as-built conditions of the dam intake arrangement using high-resolution 3D laser scanning. All required field data was collected within an 8-hour site window, minimizing operational disruption and exposure to hazardous conditions. The scan data was processed and converted into an accurate 3D model within two weeks, providing the project team with a reliable digital representation of the intake system for design and planning.
Project Highlights
- Accurate As-Built Data: Delivered a true 3D as-built model reflecting existing field conditions.
- Challenging Terrain: Eliminated the need for manual measurement in steep and hazardous areas.
- Improved Collaboration: Enabled engineers and contractors to review conditions remotely without site access.
- Retrofit-Ready Design: Provided reliable data to support accurate upgrade and retrofit engineering.
Deliverables
- Post-processed point cloud
- 3D as-built model
