Preheater tower modifications require navigating dense structural steelwork, existing downcomer ducts, and tight crane lifting radii.
1. High-Density Spatial Reality Capture
Using terrestrial LiDAR, MacProtec captured 3D spatial point clouds of the 110-meter preheater tower within 48 hours, modeling exact steel elevations, expansion joint positions, and piping runs.
2. Prefabrication & Clash Elimination
- Designed replacement cyclone inlet ducts with zero-tolerance clash detection in 3D CAD.
- Enabled 100% off-site pre-assembly and pre-insulation of duct segments.
- Reduced crane turnaround downtime from 28 planned days down to 14 days.
