Exchange Information Requirements (EIR)
The specification of what information an appointment must deliver, when, and to what standard.
Exchange Information Requirements (EIR) are the appointing party's specification of the information they need from an appointment: what is to be delivered, in what format, at which points, and to what standard. They turn a vague expectation that "we want a BIM model" into a precise, checkable brief that an appointed party can price and plan against.
The EIR sit within the wider hierarchy of requirements in ISO 19650: organizational and project information requirements describe why information is needed, and the EIR translate that into what each appointment must hand over. They are issued as part of the tender, so that bidders understand the information obligation before they commit.
The appointed party responds to the EIR with a BIM execution plan, setting out how the requirements will be met. The two documents are a matched pair: the EIR asks, the BEP answers. Under the earlier PAS 1192 standards this document was the "Employer's Information Requirements"; in Italian practice (UNI 11337) its counterpart is the Capitolato Informativo.
