New Revit-BIM LOD Standards Mean Business

Posted by Daniel Hughes on Aug 15, 2016 8:30:00 AM

I authored two articles for an Australian design + construction news site; that demonstrate Revit-BIM Level-Of-Detail (LOD) standards are not very new and how they’re driving business.

Revit-BIM Level-Of-Development (LOD) standards integrated our initial BIM Level-Of-Detail standards; which now has LOD functioning as a lightweight project management tool.

--- Design – Construction Processes Trending BIM-Dependent ---

 LOD is measuring\monitoring the projects'design + construction progress and completion deadlines. LOD is becoming a functional ingredient to Owners' BIM Execution Plans; while improving the model-building communications between project team members.

LOD is demonstrating its potential to measure Return-On-Investment (ROI) for individual Revit and/or BIM processes.

Here are the links to both articles:

Early Level-of-Detail Transitions to BIM Level-of-Development

Article #2:

BIM Level-of-Development (LOD) Driving BIM ROI

Revit Model LOD | Level of Detail - Level of Development

Posted by Daniel Hughes on Aug 5, 2016 8:30:00 AM

Defining and managing BIM models' Level of Detail (LOD) --or Level of Development is reviewed in great detail (no pun intended) by Antony McPhee, Registered Architect Melbourne, Victoria, Australia and Author of Practical BIM Blog.

Antony extensively researched his BIM LOD article; What Is This Thing Called LOD?. He provides BIM LOD Definitions from multiple countries and professional associations with descriptions and images.

Antony's LOD article serves as a great discussion tool; as BIM-based organizations define both their internal and project BIM & Revit modeling standards.

Excerpt from What Is This Thing Called LOD?,

What Exactly is Level of Development?

Therefore; a BIM Level of Development (LOD) for a chair might go:

LOD 100 = there is a chair
LOD 200 = there is a chair that has nominal space requirement of 500x500
LOD 300 = there is a chair with arm rests and wheels
LOD 400 = manufacturer and model number.
LOD 500 = manufacturer and model number, supplier, date purchased

or in General Terms:

LOD 100 = there is a thing
LOD 200 = there is a thing about this size
LOD 300 = there is a thing with these functions and options
LOD 400 = it is this particular thing.
LOD 500 = this particular thing provided by this person on this date.

Bradley Revit Family Secrets | LOD - Level of Development

Posted by Daniel Hughes on Aug 3, 2016 11:00:00 AM

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

For example;

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".

BIM LOD | Fall 2015 BIMForum Presentation Videos - PDF Downloads

Posted by Daniel Hughes on Apr 11, 2016 5:14:00 AM

Forty videos and PDF downloads are posted on the Fall 2015 BIMForum Presentations Page from their October event in Orlando, Florida.

Hours of video and dozens of PDF presentation-class documents are available for your BIM Manager monthly BIM-Revit Lunch-N-Learns.

Visit The BIMForum YouTube Video Channel to access hundreds of hours of video content for business, project and BIM standards planning and training.

BIM Level-Of-Development (LOD) was highlighted within several presentations. Those presentations providing LOD are bold-faced in the list below. I admit, I haven't listened to all the presentations on this list --as they were released 2 weeks ago. I'll update the boldfaced list of LOD presentations once I review them all.
