Trimble - Transforming the way the world works.

Trimble US Support Services will be closed on Thursday and Friday, November 23rd & 24th to observe US Thankgiving holiday. We will resume normal business hours on Monday, November 27th. Please note that Canadian Support Services will not be affected.

Using the Level of Detail (LOD) industry specifications as a guide, Trimble’s 3D Modeling Service will create a 3D model of your projects mechanical or electrical systems based on the specificity required. These models aren’t just for show and tell – these are purpose-built models for construction-caliber quantities, schedules, and estimates. You simply specify the format: AutoCAD, Revit for MEP, CADmep, Bentley Smart Plant, etc.

In today’s dynamic vertical construction environment where new technologies, standards, and file formats are driving BIM requirements across the project stakeholder spectrum, keeping current can be expensive and add un-needed risk.

Trimble’s 3D Modeling Service is a platform agnostic solution that alleviates the need for your firm to ramp-up skillsets, purchase new technology, or become BIM experts versed in the latest industry standards.As an MEP contractor you provide us with existing construction plans, models, fabrication standards and/or MEP system specifications and our team will create a functional 3D model per the project level of detail (LOD) requirements.

The BIM’s Level of Detail (LOD)---which defines how the 3D geometry of the building model can achieve different levels of refinement, is used as a measure of the service level required. On VDC Services projects Trimble offers five LOD options ranging from 200 to 500.

 

Level Of Detail

  • Level 200

    Model with approximate quantities, size, shape, location, and orientation.

    LOD 200

    • Ducts/Gravity pipe/Pressure pipes/FP Pipes: Risers and primary horizontal runs modeled with the same material.
    • All fittings modeled with the default object.
    • Primary equipment is modeled as a box with generic enveloping geometry.
  • Level 300

    Model contains system quantity, size, shape, location, and orientation detail.

    LOD 300

    • Ducts/Gravity pipes/Pressure pipes: All runs with a diameter of 2" and above are modeled.
    • All fittings modeled with the best matching fitting available in the Vico MEP Virtual Warehouse
    • Rigid conduits: All runs with a diameter of 3" or larger are modeled
  • Level 350

    Model contains system quantity, size, shape, location, and orientation detail and interfaces with other building systems.

    LOD 350

    • Ducts: flanges are modeled
    • Straight runs are modeled in segments per shop drawing piece length information
    • Ducts/Gravity pipes/pressure pipes: All runs with a diameter of 3/4" or larger are modeled
    • FP pipes: Runs of all sizes modeled
    • Flex connections to fixtures are modeled
  • Level 400

    Model contains system quantity, size, shape, location, and orientation detail with detailing, fabrication, assembly, and installation information.

    LOD 400

    • Ducts: Straight runs modeled in segments per shop drawing piece length information
    • Pressure pipes: Runs of all sizes modeled
    • All fittings modeled with the best matching fitting available in the Vico MEP Virtual Warehouse
    • Flexible conduits are modeled.
    • "Primary fixtures are Modeled with exact geometry per submittal information"
    • Instrumentation and controls: Modeled with detailed geometry to represent the outer limits of the fixture
  • Level 500

    Model contains system quantity, size, shape, location, and orientation detail with detailing, fabrication, assembly, and installation information…And includes secondary objects.

    LOD 500

    *Includes all previous LOD deliverables as well as:

    • Secondary fixtures are modeled with exact geometry.
    • All available pipe, duct and electrical connection points of secondary fixtures and controls are defined per submittals

Our recommended standard LOD is Level 350 which offers the best balance between 3D accuracy, estimating accuracy and time investment.
