La rétention à échelle mobile fait référence à la partie d'un montant de contrat dû qui est retenue à une partie contractée (la partie qui effectue les travaux) par la partie contractante (la partie qui paie les travaux). Les montants retenus sont basés sur un ensemble de normes variables définies dans le périmètre des travaux du contrat. Il s'agit d'une bonne pratique à l'échelle de l'industrie en Australie, ainsi que réglementée par la loi, pour garantir que les entrepreneurs et les sous-traitants respectent toutes les obligations contractuelles des travaux.
Although the terms of the retention on your construction project's contracts will vary from contract to contract, below is an example to show how sliding scale retention is designed to work:
Let's assume you are a general contractor who has executed a $400,000.00 subcontract with a heavy equipment operator.
During the course of the project, you plan to make progress payments to the subcontractor. Per your agreement, let's assume you have an industry-standard contract that obliges you to deduct 10% of the amount due on each subcontractor invoice until 5% ($20,000.00) of the original subcontract's value ($400,000.00) is held back.
When 100% of the work on the subcontract's Schedule of Values (SOV) is complete, your agreement obliges you to release the first portion of the amount held back. In this example, you would want to release the first 2.5% ($10,000.00) of the original subcontract's original value ($400,000.00).
In six (6) or twelve (12) months after the first portion of the retention amount was released, your subcontract's terms require you to release the remaining 2.5% ($10,000.00) withheld from the subcontractor.
