Reducing Retrofit Modeling Time by 50% for Clash-Free Facility Expansion
How a North American EPC generated an accurate AVEVA E3D model for a 14,000 m² chemical plant in just 4 weeks.
Introduction
In the high-stakes world of process industries, executing a large revamp within a strict yearly turnaround demands absolute precision. When a North American EPC Company faced an urgent schedule to retrofit new equipment into a 50-year-old chemical plant, they needed to manage a typical project challenge: ensuring the new design would fit seamlessly into the existing process tower with accurate connections and tie-ins. Even more, on a very tight schedule.
To guarantee spatial accuracy for this 14,000 m² 3-layer process tower unit, the client needed verifiable engineering truth. This required transforming raw point clouds into a highly accurate 3D model in AVEVA E3D, ready for precise design, tie-in, and rigorous clash detection before construction began.
The Challenge: Schedule Risks in an Aging Plant
Managing a 50-year-old facility means navigating high spatial risks and tight turnaround windows. Relying on traditional manual methods to capture the site reality presented unacceptable bottlenecks:
Design Clashes
Integrating modern equipment without precise spatial clarity frequently results in new components clashing with existing structures, causing severe rework.
Time & Cost Pressure
Traditional manual modeling for a unit of this scale takes 6 to 8 weeks. Waiting two months just to get the base model threatened to severely delay the engineering design phase.
The EPC needed a solution that prioritized a tight turnaround schedule without compromising the accuracy to ensure a perfect fit.
The Solution: Fast Speed "Integrated AI + Service Center"
iModel3D deployed its 'Integrated AI + Service Center' approach, specifically tailored to deliver documentation with fast speed. We moved beyond simple scanning to deliver rapid engineering data:
1. AI-Accelerated Efficiency
While accuracy was the goal, speed was the necessity. Our AI engine automated the extraction of standard piping components and structural assets. This allowed our engineering experts to focus their time on complex verification and quality assurance rather than manual tracing.
2. Comprehensive Engineering Deliverables
- Accurate AVEVA E3D Models: Detailed piping and structural models reflecting current site conditions.
- Engineering Documentation: Ready-to-use data for immediate procurement and layout planning.
3. Low Cost
By eliminating manual modeling bottlenecks, our streamlined process significantly reduced the overall service expense.
Results: Verified Reality for Seamless Integration
By focusing on accuracy and digital integrity, iModel3D delivered outcomes that directly supported the EPC's turnaround schedule:
Zero-Clash Ready
The EPC received verified AVEVA E3D models, enabling robust spatial planning and meeting all turnaround requirements.
70% Cost Reduction
High accuracy didn't come with a high price tag. The project was delivered at only 40% of the cost compared to traditional manual modeling services.
50% Schedule Reduction
The 14,000 m² unit was completely modeled in just 4 weeks, rather than the traditional 7 to 9 weeks, drastically reducing project schedule risks.
"Using the highly accurate design model converted from the point cloud using AI, we provided the accurate data foundation essential for a clash-free retrofit project with tight turnaround schedule."
Conclusion
For active industrial assets, iModel3D eliminates the uncertainty of spatial clashes by providing precise, engineering-grade documentation. We help you meet turnaround schedules faster and more affordably than ever before.
