AIA E-202, G-202, and BIMForum on the Path to IPD

Snip from E-202

The Element table started in E-202, and has migrated to the G-202, and well beyond…

Defining roles on a team is of primary concern at any project Kick-off Meeting. It’s all the more important as BIM-capable teams try integrated delivery techniques.

The structure and form of the AIA E-202 (2008) was the AIA’s first exhibit in its suite of legal instruments to help architects define BIM Manager roles on any team attempting an integrated workflow. On many of the teams I work with, that document was largely considered incomplete. It might sketch modeling expectations, but it was a poor tool to answer detailed questions about who-delivers-what-when.

Many of the exhibit’s tables and language have since migrated into the AIA G-202 (2013). This document is frequently intended to be used with the BIMForums Specification for Building Information Models to more clearly define modeling expectations on a design team. It’s a welcome step up in detail, but many of the professionals I have talked with are frustrated that the document’s language is hobbled — it has to be general enough (in part) to be used irrespective of platform.

The NYC School Construction Authority (SCA) has taken these kick-off declarations a step further. If you flip through the SCA BIM Standards Manual, you will see they have specified many of the same relationships — sometimes borrowing wording from the E-202 — but in their own procurement documentation. The General Service Administration (GSA) has done the same for building projects at the Federal level.

This follows a pattern I’m seeing in several large architecture firms. I have been invited to comment on several firms’ “BIM Project Manual” (or “Execution Plans,” or “Guidebook”) over the last year. Each has done the same as the SCA and GSA — borrowing forms, tables, LoD definitions, and titles from these forms.

For IPD, it appears that the profession has voted with its feet. If a design team hopes to communicate with spatial tools (BIM and other digital models), it will have to plan a list of issues at the beginning: When will model exchanges happen? What detail will each future meeting discuss? Who will integrate any particular model element? For anyone beginning this delivery method, start in the G-202 and BIMForm Specification, and let me know if I can help.
