3D BIM Model for Virtual Design and Clash Detection

3D BIM Model for Virtual Design and Clash Detection
I am very happy that your team was expeditious with the scanning and the model creation. My last experience with a different company did not go as smooth and I am glad to have found a reliable company to work with in the future.

Highlights

THE BOTTOM LINE

Providing both a 3D BIM model and a 2D reflected ceiling plan allowed various trades and MEP professionals to work without disturbing each other's timelines, to finish the project with fewer mistakes, reworks, and less cost.

PROJECT APPLICATION

3D laser scanning was applied to the building shell and existing structural elements. The raw point cloud data was then used to create a 3D BIM model, and a reflected ceiling plan, accurate to within 6mm, so that each trade could plan and execute their work without costly reworks and mistakes.

ASK

The VDC engineer needed an accurate BIM model for project coordination, planning, and scheduling. Virtual design and construction (VDC) engineers manage the planning, visualization, and computer modeling of building projects. They work closely with BIM modelers, architects, and clients to create a cohesive construction plan.

Task

Use 3D laser scanning to create a BIM model for new construction coordination in Paoli, Pennsylvania.

PROBLEM

  • Only the building shell existed, but did include the foundation, structural skeleton, columns, beams, and fire suppression system piping
  • A BIM model was requested to complete the design, minimize clashes, and plan for field coordination
  • The VDC engineer wanted each trade to be able to conduct their specific work without interference from other trades

Solution

  • A 3D Revit model was created from the point cloud with standard detail that included architectural, structural, and MEP features
  • A reflected ceiling plan, an architectural drawing that shows visible objects located on the ceiling of a space, was delivered for MEP coordination
  • 2D plans and 3D models allowed this client to complete the design, communicate the scope of work to each trade, and efficiently schedule work to be completed

Benefits

  • Model-based implementations are the foundation of our client’s VDC department. They plan site layout and work sequencing for efficient logistics and safety.
  • Because the VDC engineer received an accurate as-built model to place all building components and MEP into, they were able to effectively plan and communicate to minimize trade interference, clashes, installation problems, rework, and additional costs
