Construction Loan Drawdowns & Progress Payments | DeMarque
The single biggest surprise in construction finance — for first-time developers and owner-builders commissioning a project alike — is that the money doesn’t arrive. Not all at once, anyway. A construction facility is approved as a total limit but released in stages, each one tied to work actually completed on site. Understanding that machinery — drawdowns, progress claims, quantity surveyor sign-offs, retention — is the difference between a build that funds smoothly and one that stalls waiting for money that was never going to arrive the way you assumed.
Why Construction Funds Are Staged
The logic is security. On day one of a project, the lender’s security is land plus a plan; the completed asset the loan is really priced against doesn’t exist yet. Releasing the full loan up front would mean lending against value that hasn’t been built. So the facility drip-feeds: funds are released as construction adds value, keeping the loan roughly in step with the security beneath it at every point of the build.
The practical consequence: interest is generally charged only on what has been drawn, not the whole approved limit — so the interest cost starts small and builds with the project. That’s one of several ways construction pricing differs from a normal loan, covered fully in our guide to construction finance costs and feasibility.
The Drawdown Schedule
Before settlement, the build program is mapped to a drawdown schedule — typically aligned to the payment stages in the building contract. On a standard residential build these follow familiar milestones (deposit, base, frame, lock-up, fixing, completion); on larger or commercial projects the schedule follows the contractor’s progress claims, often monthly.
Each drawdown follows the same loop:
-
The builder completes a stage or submits a progress claim for work done.
-
The claim is verified — by a valuer on simpler projects, or a quantity surveyor on larger ones (more below).
-
The lender releases funds for the verified amount — usually paid to the builder directly, not to the borrower.
-
The loan balance, and the interest being charged, step up accordingly.
DMF Insight: The schedule is only as good as its match to the building contract. The most common funding stall we see is a mismatch — a contract stage the lender’s schedule doesn’t recognise, or a claim front-loaded beyond the work done. Aligning the two before settlement costs a conversation; fixing it mid-build costs weeks.
The Quantity Surveyor’s Role
On development-scale projects, the lender appoints a quantity surveyor (QS) as its eyes on site. The QS typically reviews the build cost estimate before the facility settles (confirming the project can actually be built for the budgeted cost), then certifies each progress claim: is the work claimed genuinely done, and is the amount consistent with the contract and the remaining budget?
Two things follow that borrowers should plan for. QS certification takes time — days, not minutes — so claims need lodging with the assessment window in mind, and the QS’s costs are borne by the project. And the QS’s central test at every claim is cost to complete: after this drawdown, does enough money remain in the facility to finish the build? A project that lets claims run ahead of progress fails that test, and the lender can pause funding until it’s restored — which is exactly the scenario the QS exists to prevent.
Retention and the Final Payment
Building contracts commonly include retention — a portion of each progress payment held back (or a bank guarantee provided in its place) as security for defects, released progressively at practical completion and after the defect liability period. Lenders mirror that discipline at the facility level: the final drawdown is typically conditional on completion evidence — occupancy or completion certificates, final inspections, sometimes certified as-built documentation — before the last funds move.
For cash flow planning, this means the end of the build is not the end of the money movement: the last claim, the retention release and any final certification costs land after the site work finishes, and they need to be in the feasibility from day one.

What This Means for Borrowers
-
Your equity usually goes in first. Most facilities require the borrower’s contribution to be spent before the lender’s funds start flowing — plan liquidity around that sequencing, not just the totals.
-
Interest accrues on the drawn balance and most construction facilities capitalise it into the loan — the feasibility needs to carry that growing balance to completion.
-
Delays cost twice — extended interest on drawn funds and extended holding costs — which is why lenders scrutinise the program as hard as the budget.
-
Getting funded at all depends on the project clearing the lender’s qualification gates before any of this machinery starts — presales, leverage limits and coverage tests are their own subject, covered in presales and LVR requirements in development finance.
Final Thoughts
Progress payments aren’t bureaucracy — they’re the mechanism that lets a lender fund an asset that doesn’t exist yet. A borrower who aligns the building contract with the drawdown schedule, budgets for the QS process, and plans cash flow around staged releases and retention will find construction finance behaves predictably. The wider picture — what these facilities fund and how they’re assessed — lives on our construction and development finance page.
