Point cloud MEP As-Built application
This project consisted in the scanning of the progressive works during the modification of a mechanical, electrical, and plumbing (MEP) system in a live building in Acton London.
Output for the work was the production of an As-Built 3D model of the new system installed to be reviewed and kept by the client for future maintenance and building intervention.
Reverse workflow challenge
Common workflows start from a laser scan of the plant for the production of a Revit model that can be used as a base for the new design. This allows Engineers to prevent clashes with the existing system and avoid site delays.
As-built models are a vital part of the MEP design process. The as-built model is created with 3D scanning technology, which is the most efficient way to capture all the required information.
In this case Scope of work was to follow the construction process to develop an As-Built model to be presented to the client as a record. The BES team worked closely with the site team to produce a final Revit as-Built model. The point clouds were revised and merged in order to produce a high quality as-built model. The BES team was tasked with surveying the site, processing the point clouds, and generating an accurate Revit model.
BES approach to the project
BES team used different specialized software to confront, merge and analyze point clouds taken during construction phases to obtain the final As-Built model. We used a cloud computing platform for storage and analysis, an integrated 3D modeling software for visualization of the data and a point cloud processing software for extracting the necessary information from the point clouds. As a result we produced an accurate Revit MEP model within budget and program.
