Case Study Highlights

Point Cloud to BIM for an International Broadcast Centre

The Client:

• Industry: 3D laser scanning & BIM
• Location: Australia

The Objective:

• Convert 3D scanned point cloud data of an international broadcast center into an information rich, intelligent BIM, with LOD -300.

The Solution:

• BIM experts resurfaced the point cloud models into 3D BIM (LOD-300), ready to be loaded with the required information.

The Challenges:

• The client wanted us to detect and rectify errors in the point cloud with accurate BIM modeling within 24 days.
• The total data size provided by client was about 185 GB & to work with such heavy data files was really a difficult task.
• The input files were in the form of 3D scanned images in which few of the scanned inputs were not clear & some of the building data was missing due to improper scanning, leading to complexity of resurfacing and modeling.
• The building area was large and also consisted of complex steel structure.

Technology / Software Used:

• Revit, Recap

Benefits:

• 3D Scanned images of International Broadcast centre were resurfaced and converted into BIM, replete with all the architectural and structural details.
• 10 mm accuracy helped create error free and intelligent Building information models and LOD -30 was maintained.
• Project delivery done well within the deadline resulting in decreased overall project time.

BIM is gaining wide acceptance across the AEC industry. When loaded with information this information rich 3D model, i.e. BIM becomes a great source to refer for project planning, scheduling, cost estimation, achieving sustainability solutions, facility management, repair and renovation work and more. Client Company, one of the leading players in 3D laser scanning & BIM headquartered in Australia approached Australian Design and Drafting Services for surface
reconstruction and conversion of scanned data of an International broadcast centre into an intelligent BIM. Client conducted a survey of the ‘As built structure’ and derived point cloud data via laser scanning. 185 GB of scanned data was provided, and a BIM with level of detail – 300 was requested.

The Solution:

• Modelers imported all the scanned images in Revit, and a modelfile was set up. 10mm accuracy modeling was done.
• The scanning was not up to the mark, however extra efforts were put in, flaws were mitigated and a the building data that was missing was virtually created, based on engineering assumptions and parametric images.
• The company communicated several project details, assumptions and requirements with the client and finally, successfully created an architectural and structural building information model.
