AIA announces new BIM document E202-2008

The AIA has introduced AIA document E202-2008, Building Information Modeling (BIM) Protocol Exhibit

Advertisement

E202™ is not a stand-alone AIA agreement document but must be attached as an exhibit to another AIA agreement for design, construction or services. The AIA wrote E202 specifically to foster the adoption of BIM within the design-building industry.

Practitioners from across the industry have collectively help write AIA E202 to provide a solid contractual structure for managing Building Information Modeling (BIM) across a project. This document says the AIA “creates an environment that encourages model authors to share their models with downstream users, designers contractors, schedulers, cost estimators and fabricators.”

AIA E202-2008

This document to be attached as an exhibit to either new IPD agreements or more traditional AIA agreements does all of the following:

  • Specifies who is responsible for authoring each element of the model at each project phase, so no major design elements are missed or left unaddressed.
  • Defines the extent to which downstream model users, such as contractors and fabricators, can use and rely on the model for scheduling, pricing, fabricating and construction.
  • Assigns management of the model to a specific party by project phase, so there’s no confusion about who is managing the model at any time.
  • Clarifies who owns the model and who has the right to use it.
  • Allows easy modification to add or delete model elements and to revise the required levels of development on a project-by-project basis.
  • Establishes standards and file formats to promote “interoperability” across the project.
  • Provides common definitions for terms to avoid confusion.

A table in the document assigns authorship of each model element by project phase. E202-2008 was written primarily to support a project using Integrated Project Delivery (IPD). However, it can be attached to more traditional agreements.

  1. And still no native Contract Documents for the Mac. What are the figures these days of percentage of AIA members on Mac?

  2. The AIA is supposedly really looking at a cross-platform solution now. We have heard word from the AIA itself on this. We need to interview them to learn more however and we have not scheduled that talk. They are investigating this as part of their procurement process for development. That is how I understand it.

    One of the primary issues I have with AIA Documents is its dependence on MS Office. If you look at what national and some US state governments are doing they are standardizing around the industry-neutral open documents format. I think that is a good trend and for Mac-based architects there are options for moving and supporting that direction. One good one is IBM’s Lotus Symphony Suite for Mac, currently in beta but very good and robust so far. I use it personally.

    By embracing open standards the AIA can encourage and foster the availability and use of more tools, thereby giving its members a more enriched environment of software tool choices. Competition between tools vendors is key to innovation and stagnation of innovation through hand-outs, impartial adoptions, and arbitrary de facto standards is the very type of thing that has injured the US’s automobile industry.

  3. I agree open standards are key. I am skeptical however that AIA is actually developing this. I’ve heard for _years_ that a Mac version of AIA is in the works, but no love. If you have specific information about what AIA is actually up to, I’d love to hear it. On the other hand, this might be a good time to start a petition. And what are the percentages of Mac architects in the US?

  4. The percentages of Mac-based architects are holding steady and have been for years. That is the information we have collected from discussions with market shares for cross-platform CAD players serving the AEC space and architects in particular. In fact, Nemetschek NA said at their Press Day event this past fall for 2009 that Mac share has seen a small gain and believed it was commensurate with and reflective of Apple’s gross market share gains.

  5. Yes, but you haven’t answered my question, specifically: what percentages of registered architects in the US use Macs as their primary workstation?

  6. I can’t really answer that right now. Architosh has done no work recently to help calculate that with accuracy.

    I suspect that in the US market share dropped to about 10 percent of all architecture firms (not all architects) — at its lowest — and that at one time it was around 15 percent based on a collection of information we had. That was many years ago. I suspect that we are somewhere between those two numbers now but growing with a solid pickup.

    Apple could own this market if it wanted to and those in the know, who have been in this industry and who are intimately familiar with how Apple operates and what it has the potential of doing, know this.

    But I believe the issue is as its always been with Apple. They simply do not want to swim against the current on this one. And so they have made only half-hearted attempts at addressing the challenge. That is not to say that those involved made anything less than 100 percent. Not true at all! But at the highest level the decision has not been made to say, “we want this market back, let’s go get it.”

    At any rate, Apple mac share grows and people are coming back to the fold. And with Apple’s growing cash balance approaching nearly $50 billion in about two/three years time…at that moment the company (circa 2010-11) will be in a position to buy its way back to dominance in AEC if it so chooses to execute at that level. I believe Apple won’t have to do that.
