Auto pipe extraction found majority of the pipesSome manual work needed, but this is pretty quick and easyNeeded to manually extract about 25% additional pipes and extend/connect those that were foundTip: be methodical in moving around the site finish an area before moving onTip: For UK users, make sure you use the US Metric Systems templateEdgeWise MEPEdgeWise in Action

About the ProjectTechnology Academy Building

2-story Building Expansion and retro-fit.Scan area: 34,000 ft2.Client; College DistrictProvide point cloud and prepare a REVIT Model.Client needed the updated As-Built conditions of the building Required a high level of detail.

Coordination of scanning during ongoing construction operationsScanner locations obstructed by equipment and construction materialsDim lighting requiring battery operated lights

Unique Challenges FacedTechnology Academy Building

Smaller diameter pipe has to have sufficient point cloud coverage so It can be extracted manually.More scans had to be taken due to the density and size of the piping.Creating the level of detail needed in REVIT Model was a key challenge.Unique Challenges FacedTechnology Academy Building

Dense structural features interfered with the scanner line of site for the piping3D Modeling of unique non-standard structural featuresClient required the model to show any blocking and supports added as additional structural reinforcement during construction process.

Unique Challenges FacedTechnology Academy Building

Firm NameCreated scanner location map for each floor.On site field recon to verify site conditions and access.Used FARO x330 Scanner.Used battery LED work lights in some rooms for photo draped color scans.Scans were performed during ongoing construction. Required close coordination with GC.

Field Collection Workflow Pre-Planning

Firm NameNumber of controlled scans: 134Field collection time: 7 daysExisting multi story building with drop ceilings, interior walls and existing rooms.Project had to be in contractors coordinate system.Registration software used: FARO Scene

Field Collection Workflow Field Operations

Created Clear View and Recap point clouds Working copies of point clouds were stored locally on workstations.Extracted walls, structure, and piping in Edgewise. Point cloud and auto extraction was ran overnight.Minimizes potential errors in human judgement.

Back-office Modeling WorkflowTechnology Academy Building

2 modelers worked together in parallel. One working on mechanical features and Revit model, and the other working on Steel and piping details.A great deal of user extraction of smaller piping and custom structural details was necessary.Back-office Modeling WorkflowTechnology Academy Building

REVIT files were updated with extracted elements.Wall openings and Custom features were modeled in Revit using a ReCap pointcloud. Revit project files were stored on server location.

Back-office Modeling WorkflowTechnology Academy Building

Firm Name

Our Client needed a Revit as-built which reflected detailed Reality Capture of the building.Finished Project was 244GB of data.We also provided the full registered point cloud as Autodesk ReCap files.

Final Deliverables

Edgewise Workflow Time SavingsTechnology Academy BuildingOld Workflow: 160+ hoursEdgewise Workflow: 80 HoursBy extracting walls, structure and piping in Edgewise we achieved a 50% cost savings in the modeling workflow.

As for any project, the keys to success are:A well defined scope of work and a very specific and detailed description of the level of details to be shown in the CAD/Revit Model. For this project:Highly detailed and non-standard Structural features.Small diameter conduits.Non-standard HVAC features.
