Contract DocumentsContract Documents
AIA Contract Documents are divided into eight families based on project type or delivery method. Documents in each family provide a consistent structure and text base to support the major relationships on a design and construction project. Understanding AIA document families will help you select the most appropriate standard forms for your project.
Follow links in the table for a synopsis of documents in each family, and after the table for a list of document titles in each family. The table also includes two groups not branded as AIA document families: Digital Practice Documents, and Contract Administration and Project Management Forms. Users should exercise independent judgment and may require the advice of legal counsel on deciding which documents are appropriate for a particular project.
DOCUMENT FAMILIES |
TYPE OF PROJECT |
DESCRIPTION |
SIZE |
Conventional (A201) Family |
When the owner's project is divided into separate contracts for design (with the architect) and construction (with one or more contractors), it may be appropriate to use the A201 family. |
This is the most commonly used family of documents because it is suitable for the conventional delivery approach of design-bid-build. |
Small to large projects |
Construction Manager as Adviser (CMa) Family |
When the owner's project incorporates a fourth prime player—the construction manager—on the construction team (owner, architect and contractor) to act as an independent adviser on construction management matters through the course of both design and construction, use of the CMa family may be appropriate. |
The Construction Manager as Adviser (CMa) approach enhances the level of expertise applied to managing a project from start to finish. In its purest form, this approach preserves the CMa's independent judgment, keeping that individual from being influenced by any monetary interest in the actual labor and materials incorporated in the construction work. |
Small to large public and private sector projects |
When the owner's project employs a construction manager who will complete the construction and also provide construction management services, use of the CMc family may be appropriate. |
Under the Construction Manager as Constructor (CMc) approach, the functions of contractor and construction manager are merged and assigned to one entity that may or may not give a guaranteed maximum price, but which typically assumes control over the construction work by direct contracts with the subcontractors. |
Small to large private sector projects | |
Design-Build Family |
The Design-Build family is used where the project delivery method is design-build. |
In design-build project delivery, the owner enters into a contract with a design-builder who is obligated to design and construct the project. The design-builder then enters into contracts with architects and construction contractors, as needed. |
Small to large projects |
Integrated Project Delivery (IPD) Family |
Integrated project delivery (IPD) is a collaborative project delivery approach that utilizes the talents and insights of all project participants through all phases of design and construction. |
The AIA provides agreements for three levels of integrated project delivery. Transitional Forms are modeled after existing construction manager agreements and offer a comfortable first step into integrated project delivery. The Multi-Party Agreement is a single agreement that the parties can use to design and construct a project utilizing integrated project delivery. The Single Purpose Entity (SPE) creates a limited liability company for the purpose of planning, designing and constructing the project. The SPE allows for complete sharing of risk and reward in a fully integrated collaborative process. |
Large private sector commercial projects |
Interiors Family |
Use of the Interiors family is appropriate for furniture, furnishings and equipment (FF&E) procurement services and for FF&E procurement combined with architectural interior design and construction services. |
The Interiors documents procure FF&E under a contract separate from design services, preserving the architect's independence from any monetary interest in the sale of those goods. AIA Document B152 may be used as the owner/architect agreement for the design of both FF&E and architectural interiors. AIA Document B153 is not suitable for construction work, such as major tenant improvements, and is used for design services related solely to FF&E. |
Small to large tenant projects |
International Family |
The International family is for U.S. architects working on projects located in foreign countries. |
Because U.S. architects usually are not licensed in the foreign country where a project is located, these agreements identify the U.S. architect as a consultant, rather than an architect. |
Small to large projects |
Small Projects Family |
Use of the Small Projects family may be appropriate when a project is straightforward in design; of short duration (less than one year from start of design to completion of construction); without delivery complications, such as competitive bidding; and when project team members already have working relationships. |
This family is suitable for residential project, small commercial projects, or other projects of relatively low cost and brief duration. |
Small projects |
Digital Practice Documents |
These documents may be used for any projects involving digital data or Building Information Modeling. |
AIA Document C106 provides a licensing agreement for transmission of digital data when not included in the prime agreement. AIA Documents E201 and E202 are exhibits that establish protocols for managing digital data and Building Information Modeling. |
Small to large projects |
Contract Administration & Project Management Forms |
These forms are generally useful for all project delivery methods. |
The variety of forms in this group includes qualification statements, bonds, requests for information, change orders, construction change directives, and payment applications and certificates. |
