# Writing the EIR (capitolato informativo)

> The EIR (capitolato informativo) is the document in which the client sets a project's information requirements. In Italian public contracts it is required whenever BIM is adopted: Annex I.9 of Legislative Decree 36/2023 sets its minimum contents (requirements and level of information need, production and delivery rules, common data environment, interoperability). It is attached to the tender documents; on that basis bidders submit an information management proposal (oGI) and the winner a BIM execution plan (pGI).

The EIR (in Italy, capitolato informativo) tells appointed parties which information is needed, in which form, when and through which data environment. We write it with the contracting authority or the private client, under Annex I.9 of Legislative Decree 36/2023, ISO 19650-2 and UNI/TR 11337-6, then check that bids and BIM execution plans comply with it.

## What we deliver

## FAQ

**Who writes the EIR?**

The client. In Italian public contracts the contracting authority prepares it, usually with the information-flow coordinator in the RUP's support team, and it forms part of the design brief. It can be supported by external consultants such as BIMON, while decisions stay with the authority.

**What must it contain as a minimum?**

For design services Annex I.9 (paragraph 8) requires: general and specific strategic information requirements, including levels of information need; production, management, exchange and archiving requirements, with any existing-condition models; characteristics, ownership, access and security of the common data environment; long-term interoperability specifications.

**What is the difference between EIR, oGI and pGI?**

The EIR belongs to the client and says what is needed. The information management proposal (oGI) belongs to the bidder and explains at tender how it will meet the EIR. The BIM execution plan (pGI) belongs to the winner; it is written after signing and before execution, and becomes the operating reference for the project.

**Is there a standard EIR?**

There are reference structures, such as UNI/TR 11337-6 and the 2026 Ministry guidelines, but an EIR copied from another tender usually asks for things nobody needs and forgets the ones that matter. The structure can be reused; the requirements are written for the project.

**Is an EIR needed if BIM is not mandatory?**

If the authority adopts BIM voluntarily (art. 43(2)), the same Annex I.9 rules apply, EIR included. For a private client it is not a legal duty, but without written requirements it is hard to demand usable models.
