Key BIM Services for MEP Design Firms:

  • Design Development & Coordination  – BIM engineering adds value to construction through improving MEP designs from the conceptual design-build stage to construction. The design development technique evolves from schematic and detailed design development to construction documentation.
    • BIM Modeling – BIM Modeling identifies constructability and design issues accurately. MEP engineers get clarity in designs related to aesthetics, clearance, tolerance and communicate construction ideas effectively. The centralized model ensures a coherent building plan with sections and elevations so that they could be directly produced from the model.
  • Design Engineering & Validation – BIM Design Engineering facilitates in creating complex building models, allowing MEP design firms to reduce the risk of costly changes at a later stage.
  • Design development for mechanical ducting encompassing load analysis, CFM (Cubic feet per minute) calculations, duct routing optimization, sizing, etc. 
  • Plumbing design through Building Information Modeling includes assigning fixtures, checking obstructions to sprinkler spray, providing flush valves, etc.
  •  Electrical validations include energy analysis, voltage drop calculation, short circuit current calculation, etc.
  • Construction Drawing Creation – BIM Model facilitates in producing comprehensive MEP drawings, with technical information. The consistent and cohesive drawings from the 3D model enable accurate MEP coordination with several other trades.
  • Quantity Take-Off – Quantities are also produced from 3D models for MEP design firms. Extracting the quantities through MEP Revit Model helps to make accurate cost estimations for determining designs with the project budget. Consequently, this enables team members to collaborate effectively, allowing designers to explore designs and make the right decisions for cost reduction and energy saving.

What is Scan to BIM?

  • The technique involves BIM model creation from a 3D scan.
  • During laser scanning, 3D scans are captured and imported into BIM software, such as Vectorworks, or Revit.

Benefits of Scan to BIM Services for Construction:

  • Cost-effective construction
  • Improved renovation
  • Faster decision-making
  • Cost control

Challenges involved in the Conventional Process:

The conventional process involves manual measurement, design as well as completion of construction through as-built capture, sketches, and overlay. This resulted in:

  • Inaccurate measurement
  • Difficulty in tracing measurements over hard copies
  • Illegible handwriting, leading to safety hazards, multiple on-site visits & delays

What is the Scan to BIM Process?

The technique involves scanning, processing, and modeling along with as-built. The steps include:

  1. Identifying Level of Detail (LOD):
  • Determining the level of detail for the 3d BIM modeling.
  • Accuracy and greater reliability of the as-built model.
  • Information identified at this stage encompasses building elements, level of detail, and non-geometric attributes.
  • A detailed model calls for enhanced cost and so the data density is rightly balanced with the price.
  1. Making the Plan:
  • Fixing parameters, as it becomes difficult to find out existing construction documentation like:
  • Space and angular resolution
  • Accuracy
  • Coverage

  1. Using the 3D model in BIM:
  • At this stage, the scan gets converted into a BIM model with as-built capture of an existing building structure.

How do BIM engineers work with point cloud to BIM modeling services?

  • Laser scan point cloud modeling companies develop Revit (.rvt) and CAD (.dwg) files from various scans as well as point cloud data capture machines like Leica, Faro, Trimble, Reigl, etc.
  • Engineers convert data format ( .fls, .pcg, .obj, .ptg, etc.) into BIM Revit model.
  • An information-rich BIM 3D Model is created for clash-free integration amongst architectural, structural, and MEP services.

2 facets of the scan to BIM process:

  • Interpreting Point Cloud Data: Point cloud scan of the construction project gets imported into 3D laser scanning BIM software, like Autodesk Recap.
