C105–2005 provides a standard form agreement between two architects, where one architect serves as a consultant to the other. The document allows the architects to develop a contractual relationship, but it does not set forth a particular scope of services since this will vary between the two architects.
Article 11 in the agreement provides a location where the parties can describe the services the consulting architect will provide. C105 assumes and references a preexisting owner-architect agreement, such as the B141 or B151, which is known as the prime agreement. The C105 is appropriate for use with a variety of compensation methods.
C105 may be used in any situation in which the architect who holds a prime agreement with the client retains another architect to perform consulting services. Such services could include, without limitation, programming, schematic design, contract documents, specifications, and construction contract administration.
C105 is not intended to be used when two architects desire to establish a joint venture agreement. Instead, C801™-1993 should be used.
