Detailed explanation
A construction timeline is part finance process and part building process. Before a lender starts releasing funds, the borrower usually needs land ownership or a land contract, building plans and specifications, a signed building contract, and the required approval path such as permits or certificates. Once approved, funds are released in stages until completion and final sign off.
How the timeline usually unfolds
Most construction projects move through these broad phases:
site or land secured- plans, engineering and approvals prepared
- fixed price build contract finalised
- lender approval and valuation
- progress draw construction stages
The project then moves into completion, certification and normal loan repayments once the build is finished.
Construction stages and timing checkpoints
Most financed builds follow standard draw stages after approval:
- 01 Deposit
- →
- 02 Slab or base
- →
- 03 Frame
- →
- 04 Lock up
- →
- 05 Fixing
- →
- 06 Completion
At each stage:
Builder submits invoice- lender or valuer checks stage completion where required
- funds paid to builder
- interest calculated on drawn balance only
Typical timeframes across the project
Before and during construction
approval review can often take around 1 to 3 weeks once documents are complete- first draw may need to happen within the lender validity window
- each progress draw can take a few business days after invoice and checks
- weather, variations and permit issues can extend the build timeline
Completion phase
-
final inspection and outstanding items resolved
-
occupation or final sign off obtained where required
-
loan converts to full repayment structure after completion

Common problems
Construction timelines often drift when approvals, documentation, builder availability or funding conditions do not line up.
Approvals take longer than expected
Delays with permits, certificates or amended plans can push back the entire finance and build schedule.
Possible solutions include:
- finalise plans earlier
- confirm approval pathway before applying
- allow buffer time before contract dates
- keep lender updated if documents change
Builder timing slips
Trades, materials, weather and variations can extend the construction period beyond the original schedule.
Possible solutions include:
- build in contingency time
- monitor stage dates closely
- request lender extensions early if needed
- keep evidence of delays and variations
Final completion is not ready for sign off
Even after the building works are largely done, missing certificates or unfinished items can delay the final stage.
Possible solutions include:
- finish defect items promptly
- collect certificates and compliance documents
- coordinate final inspection early
- prepare for loan conversion after handover
