Selaras dengan jawaban untuk submittal, saya berpendapat istilah ini layak diserap saja.

Halaman ini patut menjadi bahan pertimbangan:

For most purposes, Submittals and Transmittals are documents exchanged during a building project, typically amongst Architects, Engineers and Construction (AEC) professionals. Most industries consider Submittals to be more of a preliminary step in the building process, sent with the expectation of forthcoming revisions or a request to be answered therein. Transmittals are typically sent as records, documentation or required materials (such as CAD drawing files) for the project. While Transmittals are still open to revision and collaboration, the sender is usually not seeking such changes or requesting the type of feedback as though it were a Submittal.(other than receipt confirmation of the Transmittal)

👷 Jadi, mungkin submital dan transmital berkenaan atau berisi dokumen yang sama (misalnya diagram pengawatan), namun yang pertama akan meminta tanggapan, sementara yang kedua bersifat informasi searah.

👷 Saya kira memang sulit menemukan padanan yang menggambarkan sifat-sifat tersebut, sehingga lebih baik diserap saja untuk saat ini.
