Gatehouse in Sheffield – Laser Scanning and Revit Survey

Gatehouse in Revit

We’ve recently found ourselves undertaking a laser-scanned survey in Sheffield of an eye-catching gatehouse in Kenwood Hall.  Our commissioners, Franklin Ellis Architects expressed the need for a BIM ready 3D survey.

For this project we used our Faro X130 laser scanner to capture both the exterior and interior of the building, we then moved into the data registration stage ensuring accurate alignment and positioning of each scan position. By carefully merging together both grey-scale and RBG colour scans and inputting the coordinates of the chequerboard targets from the total station, we then were able to create a unified point cloud data file that could be afterwards exported to our chosen BIM software. In this instance, our unified rcp file was brought straight into Autodesk Revit for the modelling stage of the project.

Moving onto our building modelling phase, we encountered a lot of bespoke components on the exterior of the building, such as particular windows with stone mullions, chimney and eave details. Following the client’s requirements,these and other bespoke components required a detailed 3D representation. By creating parametric Revit ‘families’ we were able to fulfil this task by thoroughly analysing the point cloud data created in the course of the survey.

That level of detail and the accurate positioning of these bespoke components would be extremely difficult and time consuming with traditional measured survey methods.

Along with the final Revit model we always issue our clients with a Standard set of 2D Measured Building Survey Plans to aid with planning applications and for general presentation
