One progress payment, seven different numbers
They are not seven stages of one progress bar. They are seven separate questions, settled by different people, from different documents, on different days.
The work is built. The contractor has claimed. The developer has certified. The money has not left.
Those four sentences describe one progress payment. Four amounts, four dates, four different people deciding.
It took me a while to accept what that means. These are not stages of one process that you move along. They are separate questions, and each one has its own answer.
So a report that gives a period's progress payment without saying which of them it is has not yet given you a number you can act on.
01The states
Seven states, seven questions
Each state carries the same three fields: who settles it, which document it rests on, and the date it is settled on. They differ. That is the whole point.
1Built
How much physical work exists on site?
Settled byNobody alone. The contractor reports, the developer and the supervising architect measure, the construction manager checks separatelyRests onSite diaries, measurement records, photographs, inspection recordsSettled onThe observation date, meaning the day somebody looked2Claimed
How much does the contractor say it is owed for this period?
Settled byThe contractorRests onThe valuation application, with its measurement scheduleSettled onThe date it was submitted3Valuable under the contract
Under the contract's own rules, how much can be counted at the cut-off?
Settled byThe contract terms themselvesRests onThe valuation, variation and defects clauses, plus the current signed schedule of ratesSettled onThe valuation cut-off date4Certified
How much does the developer formally accept it owes for this period?
Settled byWhoever holds the developer's signing authorityRests onThe certificateSettled onThe certification date5Invoiced
On what basis is the contractor asking to be paid?
Settled byThe contractorRests onThe invoiceSettled onThe invoice date6Drawable
How much will one funding source release on a given day?
Settled byThe funder, on its own conditionsRests onFacility conditions, the trust deed, the construction manager's monitoring report, evidence that conditions precedent are metSettled onThe date the conditions were met7Paid
How much actually reached the contractor's account?
Settled byThe payment record itselfRests onRemittance advice, bank creditSettled onThe value date
02A word
One more word that has to be taken apart
"Payable" is not one of the seven, and it is a word people reach for often.
It means the amount on a given day for which every approval is complete and at least one funding source can actually release money.
It is the lower of the net certified amount and the funds drawable that day. You need both numbers. One of them alone does not produce it.
03A miscalculation
Treating a completion percentage as the drawable amount does not reliably point one way
Take the completion percentage from the monitoring report, multiply it by the contract total, and treat the result as what can be drawn this period.
That percentage is an observation from the day the monitor visited. Its base may be the direct works cost rather than the tax-inclusive total. The lender's own formula then applies a loan-to-cost ratio and deducts everything drawn to date.
Which of these three differs, and in which direction, depends on the contract’s own base, ratio and amounts already drawn; it is not safe to assume the number is always too high without checking. Schedule payments against it unchecked and the gap only shows up on the payment date itself.
04Model and statute
What the model contract says is not what the statute says
Source. The Civil Code's default is payment on completion and delivery. Where work is delivered in parts and the price is set for each part, each part is paid on its delivery.
Inference. So monthly valuation is not a statutory default. It is something the contract creates.
Public works in Taiwan have a model contract and a valuation-payment procedure that set out who signs off what, and by when. That procedure does not automatically apply to a private development. A private deal has to be read against its own construction contract, and against whatever the financing and trust documents separately say. Reading a private deal against the public model will not line up.
05Boundary
What this page does not do
It does not decide who is right, and it does not tell you whether to pay this period.
It ties a number back to the document, page, version and observation date it rests on, and marks what is missing rather than inferring it.
The chain above is set out against the public procedure and the model trust deed. A real case has to be checked against its own contract and its own trust deed.
06Sources
Where each item comes from
Source marks a summary of the provision or model contract, with its article number so the original can be checked. Inference marks what I concluded from it and have not confirmed directly. The study text this came from keeps the two apart on every line, and so does this page.
- SourceCivil Code articles 490 and 505. The default rule for a works contract is payment on completion and delivery.
- SourcePublic Construction Commission model procurement contract, 2025-12-30 revision, articles 3, 5 and 20, with the public works valuation-payment procedure. It includes no valuation before defects are made good, and no effect for a variation that was not signed in writing. Used here as a reference model only.
- SourceArchitects Act article 18. Its first three limbs describe supervision as checking construction against the drawings and checking materials; a fourth limb allows “other supervisory duties as agreed.” Whether that extends to agreeing a valuation amount depends on the engagement contract.
- SourceMandatory terms for pre-sale housing contracts, items 7-1 and 8. Construction funds follow physical progress and are ring-fenced; buyer instalments follow progress, at least 20 days apart.
- SourceTrust Association model development trust deed, article 5(3), 7(5) and 9(5). Drawing on the trust account requires a written application with supporting documents, but who reviews it and what must be attached are left blank; the construction manager is not a co-trustee; the trustee bank reviews form only.
- InferenceThe seven states are not interchangeable because different people settle them, from different documents, on different days.
