Turnaround Support
Project Overview
Engineering Design Services provided turnaround support for an industrial facility by generating and validating multiple work packages for execution during a scheduled shutdown. The project combined drone-based aerial surveying and ground-based laser scanning to capture accurate field conditions, which were then compared against existing engineering work packages. The effort focused on identifying discrepancies between design documentation and actual field configurations to ensure accurate execution during the turnaround window.
Result & Impact
• Improved worker safety by reducing the need for personnel to work at heights through drone-based surveying
• Increased operational reliability through accurate, real-time field data collection
• Eliminated reliance on outdated drawings by providing updated as-built conditions
• Enhanced construction accuracy during turnaround execution
• Delivered validated as-built 3D models for future maintenance and engineering use
• Reduced risk of rework and installation errors during critical shutdown periods
Engineering Tools & Technologies
• Ground-based & drone-based laser scanning (LiDAR)
• Point cloud processing and modeling
• 3D piping system modeling
• Construction work package development
• As-built documentation systems
• Field verification and validation techniques
Scope
• Generate multiple turnaround work packages for field execution
• Perform drone-based site surveys for aerial data capture
• Conduct ground-based laser scanning of existing piping systems
• Process and analyze point cloud data
• Compare field conditions against existing work packages and drawings
• Identify configuration discrepancies in piping systems
• Update engineering models to reflect actual field conditions
Solution
Engineering Design Services utilized advanced scanning and modeling workflows to align engineering documentation with real-world field conditions. During analysis, the team identified discrepancies such as misaligned piping components (e.g., weld-o-lets in incorrect locations) and corrected these within the updated models. Drone and laser scanning data were used to revise work packages and ensure accurate construction execution. Following the turnaround, a secondary scan was completed to confirm that installations matched the updated engineered design.
