The Manufacturing Plant in Torrance, California required high-resolution 3D laser scanning to support the replacement of equipment. Arrival 3D was commissioned to scan three lower silos and provide accurate as-built data for the client’s planned upgrades. This resulted in an LOD 200 Revit model. From this, our team generated 2D DWG plans and elevations in DWG format giving the client clear layouts for efficient equipment replacement.
A leading building materials manufacturer needed precise dimensional data of the internal silo sections to ensure new equipment could be installed without modifications or delays. The industrial plant 3D scanning project targeted specific areas outlined in the RFQ focused on confined, hard-to-reach silo interiors.
➡️Scanner Setup: Multiple Leica RTC360 positions capture visible surfaces, structural characteristics and equipment beneath the pantlegs.
➡️3D Data Collection: Focused laser scanning of confined areas beneath pantlegs, ensuring complete coverage in difficult access spaces.
➡️Data Processing: Point cloud data was registered, processed, and modeled into an LOD 200Revit file.This model generates 2D DWG plans and elevations for Draft sight software integration.
➡️ Access Issues: The areas beneath the pantlegs were confined and difficult to reach making it challenging to capture all necessary surfaces.
➡️ Solution: Arrival 3D coordinated with plant staff and carefully planned scanner positions to avoid operational disruption and work in a safe manner.
➡️Dimensional accuracy: Accurate measurements of existing equipment and structural components were required for developing a dependable as-built model.
➡️Solution: Multiple scans from various vantage points captured high detail with the structure, enabling precise and accurate modeling.
➡️ Software compatibility: The client required 2D DWG plans from Revit model that are compatible with Autodesk AutoCAD
➡️ Solution: Developed a workflow converting Revit deliverables into Draft sight-ready DWG files without loss of accuracy.
➡️ Accurate dimensional data: The Revit and 2D drawings or DWG outputs provided clear documentation of the silo interiors in a usable format for project work.
➡️ Efficient execution: Engineers executed equipment replacement confidently, knowing that the design work was done with accuracy and diligence. .
➡️ Future reference: Deliverables now serve as a long-term digital asset for ongoing maintenance and upgrades.
This project demonstrated how 3D laser scanning in industrial plants can transform complex , confined spaces into usable digital models. By combining LOD 200 modeling with 2d cad outputs, engineers gained both an immediate solution for replacement planning and a valuable archive for future projects.
Early collaboration with facility personnel ensured that the scanning went smoothly onsite, while clearly defining deliverables (Revit + DWG) minimized customer disappointment upon delivery. The project is a typical example of how reality capture technology in simplifies and improves the process of engineering projects for industrial facilities.
