Prevent costly engineering errors with the unsurpassed precision of 3D laser scanning.

3D laser scanning can improve the design, construction and operation of industrial plants and lower the risk of unsafe field conditions and structural mistakes.

The Data Speaks for Itself

Project managers from a wide variety of industries report that having complete and accurate 3D as-built information based on 3D scanning has meant reduction of rework on brownfield projects to below 2%—and often below 1% of total installed cost.

Engineered to Succeed

Compared to traditional methods, the accuracy of 3D laser scanning:


Improved Efficiency:

  • Reduces field time 50 - 70%
  • Reduces design error
  • Improves schedules
  • Reduces damages
  • Minimizes setbacks

Improved Processes:

  • Easily update P&IDs
  • Create consistent as-built documentation
  • Meet regulatory compliance requirements
  • Achieve higher levels of accuracy in demolition
  • Reduce material waste and incomplete welds
  • Resolve costly issues beforehand using accurate visualization construction plans
  • Accelerate schedules
  • Integrate scope changes quickly

Enhanced Deliverables:

  • Measure to millimeter accuracy with extensive site coverage
  • Utilize advanced clash detection methods for new installation
Prologue helped us resolve many construction coordination issues well in advance. I can say that the scans and models have more than paid for themselves.

3D Laser Services From Prologue


3D Laser Scanning

Using a 3D laser scanner, our team can collect remote measurements of large areas with an extraordinary accuracy of up to 2mm. This scanner collects up to 976,000 measurement points per second, allowing us to accurately identify and document all visible elements of a structure in a fraction of the time it would take with manual measurement. For most laser scanning projects, the time required to capture the data on-site is reduced by at least 50-70% compared to traditional survey methods.

In other words, it's time to put down the tape measure.

Data, Extraction, Modeling & Export

Using the virtualized 3D site as a guide, our modelers can swiftly generate accurate and up-to-date as-built models in Autodesk® Revit®. Since our team works with hard data—instead of manual measurements, notes and hand drawings—the time and cost spent on modeling is typically a fraction of the manual approach. And since the project’s architects don’t have to worry about modeling as-built conditions, they’re able to place their focus on design. 

Once our team has completed the model, it can be viewed from any perspective to see detailed elements within the structure. The model is then delivered in the format that best suits the client’s needs. Typical formats include Revit models, CAD drawings, orthophotos and point clouds.
