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.”
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.
