| SG3 | 1 | SG3 | Optional |
| RFF | 2 | In this segment specific internal references will be quoted, as and if required. When this segment group is used to describe the computer environment, this segment which will specify the unique reference number by which, in future, the following computer environment details for this party can be identified. | Mandatory |
| CED | 2 | By repeating this segment, it will describe, at each occurrence, one of the party's computer environments, identified in the previous RFF segment. The computer environment details will consist of, for example, hardware platform, operating system, software in use, converter etc. | Optional |
| DTM | 2 | A segment specifying the date and/or time details related to the environment details. | Optional |
| SG4 | 1 | SG4 | Optional |
| CTA | 2 | A segment to identify a person or department, and their function, to whom communications should be directed. | Mandatory |
| COM | 2 | A segment to identify a communication type and number for the contact specified in the CTA segment. | Optional |
| LOC | 2 | This segment specifies the location of the contact described in the previous CTA segment. In large organisations and construction projects it is possible that persons are not necessarily on the same internal site or construction site specified in the previous LOC segment in segment group 2. This segment also enables the specification of a more accurate internal site location. | Optional |
| SG5 | 0 | SG5 | Optional |
| DOC | 1 | This segment will give the document details of the contractual document. | Mandatory |
| INP | 1 | This segment conveys for each receiver instructions of what to do with the contractual document. | Optional |
| RFF | 1 | A segment to indicate the unique reference number of the contractual document. | Optional |
| MEA | 1 | This segment will give details about the scale used in the contractual document. | Optional |
| SG6 | 1 | SG6 | Optional |
| EFI | 2 | This segment will identify each file, that is part of the contractual document, by quoting their name and a number. | Mandatory |
| CED | 2 | The segment will give additional information about the file identified in the previous EFI segment, like for example, conversion details. | Optional |
| DTM | 2 | This segment will convey the date/time details of the computer file identified in the previous EFI segment. | Optional |
| SG7 | 0 | SG7 | Optional |
| BII | 1 | This segment will, through a structured index code, uniquely identify the set of information following this segment. | Mandatory |

| DTM | 1 | Date and time details relevant to the set of information identified in the previous BII segment (e.g. list version date). | Optional |
| IMD | 1 | This segment records the details of the set of information identified in the previous BII segment (e.g. descriptions of the hierarchical levels or objects, part of the lists). | Optional |
| RFF | 1 | This segment will give a reference to another set of information (e.g. engineering/CAD file structure referring to naming conventions given in a previously-supplied list). | Optional |
