Bradley's Revit Family models were created with a high Level Of Development (LOD). Bradley Revit models are designed to accommodate the needs of all four Revit project members; architect, engineer, contractor and facility owners.
There are several reasons the Bradley BIM Team chose to build a single Revit model; that was all-inclusive to serve all disciplines.
Bradley Revit-BIM Family Quality Standards | Top 10 FAQs
1) Logistically, its easier to manage embedded data parameters of more than 1,000 Revit models; as one inclusive model for all disciplines.
2) Ideally, a manufacturer's Revit model that is shared amongst the team; guarantees data consistency and minimizes the modeling costs for everyone. Consider this:
How often will your consultant(s) build a Revit model for both them and for your discipline?
How often do you build Revit models for your consultants?
3) Realistically, my onsite client visits confirm that BIM \ VDC Managers maintain a LOD definition; specific to their organization, projects and team members.
"We will decide what content we keep and delete within our Revit families."
[Common BIM-VDC Managers Response]
Bradley anticipated Revit Managers would remove content from Bradley Revit models; to meet their standards, preferences and criteria. It is far easier, faster and cheaper for them to delete content, from an all-inclusive Revit model.
Once they remove family content; perhaps after adding their own shared \ family parameters --they will save a Bradley Revit family file down to a smaller file size.
Bradley Revit Family Secrets – Compact File Reduces File Size
Architectural designers may remove the MEP connections, solids or voids --keeping only basic solids, masking regions and symbolic line-work.
Engineers may remove the materials, solids and voids --keeping the MEP connections and portions of the masking regions & symbolic line-work.
Contractors creating the Owner's as-built project Revit models; have typically requested and\or used the Bradley Revit models in their original high LOD format.
Technology's Exponential Growth Will Change Revit Family Rules
The Bradley BIM Initiative strategy forecasted; that Revit, LOD, BIM and supporting technology processes would remain "moving targets".
