português term (edited): auto de medi��o

Construction is often contracted on the basis of unit costs, therefore a bill of quantities is drawn up detailing each type of work and the unit prices are applied to each to arrive at the amount due

Being it a public or a private contract, an "auto de medição" is a document elaborated by the contractor which reports the monthly advance on the contract. It depends on the verification and approval from the Supervision or directly from the contract owner.
It's directly attached to the main contract document, and it reflects exactly the articles and quantity bills attached to the approved tender version.
After the approval, the "auto de medição" is then forwarded with a payment request to the contract owner, may it be the main contractor or a sub-contractor.
There can be "autos de medição" elaborated for several types or works or even services...
An example of services can be scaffold lease... where the "auto the medição" depicts the quantity's for mounting, dismounting, usage, transport, and all kind of services or products used or executed in several periods over a month.
Nevertheless, an "auto de medição" is always referencing the conditions and specific articles of the contract or it's approved amends or alterations.
I don't think it can be translated as work progress report, though it can also be submitted as a percentage bill... let's say for excavation works.
When this happens, it usually refers to works that are hardly evaluated as precise units such as sqm. or Kg and so on.
It's the case where work supervision and contractors, or subcontractors, agree to approve work progress bills by percentage executed on relation to the total estimate. Usually, this kind of work progress bills do intend to make life easier for both parties, since it's not easy to make an accurate account for certain works until they are completed. It's only then that both parties set a final quantity and make quantity encounters for that specific article in the contract, since in many cases, even in siege of contract, certain works allow fluctuation of quantities on a certain percentage of the initial estimate.
