Asked and Answered: FAQs


Are BIM’s models Constructible?

Yes, but the level of detail determines how models should be used in the field. For example, to fabricate based from a BIM model, you'll want the LOD to be 400 or above. All the different levels of development (LOD) are defined below, highlighting their potential uses. Understanding what the different levels of development will help you complete RFPs for your projects.


LOD 100 - Concept Design

The building 3D model is developed to represent the information on basic level. Thereby, only conceptual model creation is possible in this stage. Parameters like area, height, volume, location and orientation are defined.

LOD 300 - Detailed Design

Accurate modeling and shop drawings where elements are defined with specific assemblies, precise quantity, size, shape, location and orientation. Here, too, we can attach non-geometric information to the model elements

LOD 350 - Construction Documentation

It includes model details and elements that represent how building elements interface with various systems and other building elements with graphics and written definitions

LOD 500 - As-Built

Elements are modeled as constructed assemblies for Maintenance and operations. In addition to actual and accurate in size, shape, location, quantity, and orientation, non-geometric information is attached to modeled elements

How does BIM improve the Coordination process?
We are more efficient during the clash detection process. We can take, on average of 6,500 clashes, group them down and assign them to individual MEP trades in a matter of hours. Clashes are assigned to responsible trades prior to coordination meetings. During coordination, the design team only review clashes that have not been cleared.
How does BIM price each project?

We price projects two ways, all in a proposal format:

  • Lump sum
    • Contract documents are provided and a single price is given for a list of deliverables.
  • Cost Plus
    • BIM Designs partners with the contractor to handle detailing and/or engineering on a per-project basis at our cost plus 30%.
How long does the estimate process take?

On average it takes 72 hours. We do try to get estimates out within a 24 hour period.

How much should be set aside for detailing?
15-20% of man hours for a project. A detailer supports 10-12 field personnel. Supplying them everything they need from cut lengths of pipe, POC depths to Point Layout, hanger elevations, rod lengths and explanation of drawings.
How will BIM communicate with the field?
Our Lead detailers will communicate directly with General Foreman to go over any questions during the installation process.
The building is already existing, can BIM help?
We use 3D scanning technology to produce a BIM models used during coordination. We will then populate the model per the contract documents provided or created from our engineering team. The final product will be ready for fabrication or installation. A clash free model coordinated around other existing trades and structure is also produced.
What if BIM Designs is needed onsite?
BIM will come out to any project site to measure, verify and review field conditions. Added costs apply.
What software do we use?
AutoCAD Fabrication MEP, Navisworks, Revit, C4R Revit Collaboration, ProCore, BlueBeam, SharePoint.
