Bradley BIM is launching a new AIA-CES \ RCEP Accredited BIM Class in Phoenix, Arizona on Wednesday October 12, 2016 for our Bradley sales partner, PIR Sales, Chandler AZ.

Join Us for this FREE Event!

The Event in AZ Event Page has a CEU Registration Email to register for any of the for the four (4) CEU classes that will be given throughout the day.

Bradley's AIA-CES class is also registered with the Registered Continued Education Program (RECP).The class offers Professional Development Hour(s) (PDH) to RECP Members.

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'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".

I attended the AU 2013 class; which detailed the Mayo Clinic Modeling Development Specification (MDS) --developed by Mayo Clinic BIM Program Manager, Andy Jizba (Arizona) and David Paul Wilkinson, Autodesk Consulting Services.

Autodesk University Class

• Model Development Specification: Communicating the Exchange of Reliable Models

The purpose of the Model Development Specification (MDS) is to define how Building Information Modeling (BIM) will be implemented and managed on both current and future projects.

Critical to the development of the BIM is a complete understanding of how the model will be used during the course of the design, construction, and life-cycle management of the building.

Andy Jizba | Mayo Clinic BIM Program Manager (Arizona)

While Level of Development (LOD) gains traction for Revit component and project modeling; Mayo Clinic has created a contractual deliverable process that defines

• a mutually defined LOD for each discipline, by each discipline -- based on an initial, project kick-off meeting with the owner.

• how the owner plans to use BIM for the Building's Lifecycle Management and Operations & Maintenance (O&M).

• LOD roles and responsibilities at each phase of the project: Lead, Support & Use

• how to use Revit family LOD shared parameters; to monitor & manage a project's LOD progress for each discipline and phase --to minimize rework of the model.

• a method that allows each stakeholder to integrate their interdependent Revit-BIM modeling standards into the project standards.

Attorney, Krista Hallberg Kapp, Partner at the Construction Law Practice- Laurie & Brennan, LLP provides a summary of AIA 2013 BIM - Digital Data Exhibit Updates

The What, When and How of the 2013 AIA Digital Practice Documents

In 2013, The American Institute of Architects (“AIA”) released a series of contract forms to facilitate owners’ and design and construction professionals’ transmittal and use of Building Information Modeling (BIM) and digital data on a construction project.

This article provides owners and design and construction professionals with a summary of the new contract forms and when and how to utilize them.

Here are excerpts from Ms Kapp's article; where she provides the legalese of these updates

The What, When and How of the 2013 AIA Digital Practice Documents

Excerpts:

AIA Document E203 – 2013 Building Information Modeling and Digital Data Exhibit

Article 1 of the E203 provides project participants with a uniform set of definitions to be used for the development of the Protocol.

Article 2 of the E203 provides that the transmitter of digital data warrants to the receiver that the transmitter is the copyright owner of such digital data.

Article 3 of the E203 requires project participants to anticipate and list the different types of digital data that will be used by the parties.

Article 4 of the E203 provides for the establishment of a modeling Protocol if the parties agree to utilize BIM at a project.

AIA Document G201-2013-Project Digital Data Protocol Form and AIA Document G202-2013 Project Building Information Modeling Protocol Form

AIA Document G201-2013-Project Digital Data Protocol Form

Unlike the E203 that simply sets forth the parties’ intent to agree on a digital data Protocol, the G201 actually sets up the Protocol that will govern the parties’ use of digital data. The G201 is not a contract document and can be modified during the course of the project easily, without the need to modify each of the project participants’ contracts as circumstances on the project change.

AIA Document G202-2013-Project Building Modeling Protocol Form

Article 2 of the G202 introduces the term LOD or Level of Development to assist project participants in their development of a BIM Protocol. The LOD provisions set forth in the G202 provide for and define the specific minimum contents of the BIM at certain project milestones.

In mid-2008, The Associated General Contractors of America (AGC) released one of first BIM protocol guidelines; with AGC's ConsensusDocs 301 BIM Addendum.

In early 2009, The American Institute of Architects released their AIA document "E202–2008 BIM Protocol".

The BIM process continues its growth and expanded role for designing and constructing buildings; via association's contractual documents and better defined national standards.
