Retention position (v1)

You are viewing version 1

This contract has been superseded. See the current version (v2).

Retention position is one of Demiton's published registers for Australian civil construction. Retention currently withheld on a job, and its status. Demiton keeps it current from the systems a contractor already runs and publishes the record's shape as a versioned JSON Schema, so the same question works whichever system produced the record.

Part of Contracts in the register catalog.
