Monitor Your LOD Workflow in Vico Office

Are you heading to Denver in October for the AGC BIMForum?  Then you probably know how much effort has been put into the E202 and the G202.  But what you might not know is that the team at Trimble Buildings, from our roots as Vico, started work on the Model Progression Specification back in 2008.


Today, we are up to the third iteration of the MPS and have introduced many customers to the idea of classifying elements in Building Information Models. The results of our latest work, documented as a full blown methodology that uses Primitives with defined requirements for each of the development stages of BIM element types, can be downloaded below along with the accompanying webinar.


So far, most of the work related to the Model Progression Specification was planning
and documentation oriented: plans have typically been created in spreadsheets with targeted LOD's, then shared with the project team. The checking of model "readiness" after completing a new version of the BIM at the end of a design stage was therefore somewhat disconnected and involved opening BIM's and comparing model elements to the specifications written down elsewhere.


In response to the increasing adoption of the LOD concept (helped tremendously by
the recently completed BIMforum deliverable), the Trimble Buildings team is changing this. The latest version of Vico Office, release 4.6, provides integrated support for the
MPS using Tags within its Takeoff Manager module.


The workflow is straightforward:


  1. Define new Tags for "LOD" and "Target LOD" and predefine the values that you want to use (for example: 100, 200, 300, 350 and 400).
  2. Combine model content from the BIM's you receive in a Vico Office project; this can be any of the supported BIM authoring tools, which include Revit, Tekla Structures, ArchiCAD and Sketchup.
  3. For each of the element groups - Takeoff Items in Vico Office - assign a targeted LOD value. The targeted LOD value will be driven by the required quantity information for downstream processes such as cost and schedule planning.
  4. Open each of the Takeoff Items, highlight or isolate the associated elements, review quantities and determine whether - based on LOD definitions - the LOD requirements are being met with the current model version. If it does not, select the LOD value that better matches the current state of collection of elements.
  5. Communicate and review the current MPS status with the team using the visual feedback from the actual set of models and the search and filter capabilities of the Vico Office Takeoff Manager!

Caption: Here is one example how to use the new workflow: With the ability to store formats such as PDF and XLS, Vico Office Document Controller makes it possible to do design and MPS tracking with each new release of the model.  The project’s progression specification can be stored in the Vico environment, along with each 3D model, and updates can be checked against the MPS document.  Tags can be used in Takeoff Manager or Cost Planner to track the status of the model relative to the MPS
requirements for that release.


The ability to Tag your model content, purposely organized into Takeoff Items for downstream use in cost and schedule planning, with LOD information, allows project teams to define Targets, monitor progress and communicate gaps using the visual feedback of the integrated project model.

We have peeled away part of the building to reveal the 1-hour fire rated interior panels (in yellow). The Takeoff Manager now features the ability to include LOD information to determine the targeted, as well as the current level of development of the included elements.


We would love to speak to you in more detail (pardon the pun) at the upcoming AGC BIMForum in Denver. Trimble Buildings is hosting the Welcome Reception at the Denver BIMForum on Monday evening, October 7.  We look forward to meeting you and your team and hearing about your own success stories.  We’ll have local craft brews to welcome you to our backyard, plus many of our product experts from Tekla, Trimble Field Solutions, SketchUp, Vico, Prolog, and WinEst.  So please plan on joining us.


Be sure to check out our other prefab solutions, including the concrete case study for the Westminster project, the virtual mock-up case study on the Mission Hospital, and the steel case study at our Westminster campus
