Late selections, unclear scope, and rushed approvals are among the most common causes of construction delays, and most are avoidable when planning starts early. If you’re wondering when to begin making decisions about materials and finishes, the short answer is: before construction starts, ideally during the planning stage.
Here’s how to manage your building or renovation timeline from the first conversation to the final handover.
Start With a Clear Scope from Day One
One of the biggest causes of delays is uncertainty about what’s being built. If the scope of work isn’t clearly defined before work begins, changes tend to appear during construction, and each change affects the timeline.
Before work starts, confirm:
- What is included in the project
- What is not included
- Materials and finishes
- Layout and design decisions
The more decisions you settle upfront, the fewer interruptions you’ll face once construction is underway.
Allow Enough Time for Planning and Approvals
Rushing the early stages almost always creates problems later. Planning drawings, engineering reports, and council approvals each take time, particularly in NSW where development application and complying development pathways have different timeframes depending on your project type.
Trying to shortcut this stage often results in stop-work periods or redesigns, which delay the project far more than waiting for approvals in the first place. A realistic schedule accounts for approval timeframes, supplier lead times, and potential back and forth with council or certifiers.
When To Finalise Your Selections Before Construction
Material and finish selections need to be locked in before construction begins, not during it. Windows, tiles, cabinetry, and fixtures commonly have lead times ranging from several weeks to several months depending on supplier, product availability, and whether items are custom-made or imported.
If selections aren’t finalised before trades are on site, work can stall while everyone waits for materials. That stall rarely affects just one trade. Delays cascade: the tiler waits on tiles, the cabinetmaker waits on appliance dimensions, and finishing trades can’t begin until prior stages are complete.
The practical approach is to begin your selections during the planning and design stage so that everything is ordered with enough lead time to arrive before it’s needed on site.
Choose the Right Team
A reliable project team plays a significant role in keeping timelines on track. Experience matters, particularly when it comes to sequencing trades and coordinating deliveries so that one stage finishes ready for the next to begin.
Look for a team that:
- Provides a clear construction schedule from the start
- Communicates regularly and proactively
- Has established relationships with trades and suppliers
- Flags potential delays before they affect the programme
Good builders plan. They don’t wait for problems to appear before dealing with them.
Building Flexibility Into the Schedule
No project runs perfectly from start to finish. Weather, supplier delays, or unexpected site conditions can affect progress regardless of how well the project is planned.
A sensible timeline includes buffer periods to absorb these issues without derailing the entire programme. This keeps expectations realistic and can help reduce stress during a renovation when minor setbacks occur, because they’re already accounted for rather than treated as crises.
Communicate Regularly and Clearly
Poor communication leads to misunderstandings, rework, and unnecessary downtime. Regular check-ins keep everyone aligned.
Clear communication should cover:
- Progress against the schedule
- Upcoming milestones and what’s needed to reach them
- Any issues or changes that have emerged
- Decisions that require client input
When communication is open, problems get dealt with quickly rather than compounding into larger delays.
Avoid Mid-Project Changes Where Possible
Design changes during construction almost always affect the timeline. Even small changes can require rework, new approvals, or rescheduling of trades who may have moved on to other jobs.
If a change is necessary, understand how it affects timing and cost before proceeding. Making that call with full information avoids unexpected delays further down the track.
Understanding the Order of Work
Construction follows a specific sequence, and some tasks cannot begin until others are complete. Cabinetry can’t be installed before walls are finished. Tiling can’t start before waterproofing is done and tested. Final fixing trades can’t operate in a space that’s still being plastered.
Understanding this sequence helps manage expectations when certain stages appear to move slowly. What looks like inactivity is often the correct wait between dependent tasks.
Track Progress Against the Timeline
A schedule only works if it’s actively managed. Regularly reviewing progress against the programme helps identify potential slippage early, when adjustments are still straightforward.
Staying engaged doesn’t mean micromanaging, but it does mean being informed about where the project sits relative to key milestones.

Frequently Asked Questions
When should I start selections to avoid construction delays?
Finalise material and finish selections before construction begins, ideally during the planning stage. Items like windows, tiles, and cabinetry can have long lead times, so locking them in early keeps trades moving and prevents a domino effect on the schedule.
What happens if I change my mind about materials after construction starts?
Mid-project changes can require rescheduling trades, sourcing different materials, or in some cases seeking updated approvals. The timeline and cost impact depends on how far along construction is and what the change involves.
Understanding those consequences before making the change helps you decide whether to proceed.
How long do council approvals typically take in NSW?
Timeframes vary depending on the approval pathway and council. Complying development can be faster than a full development application, but both require time for assessment. Building this into the schedule from the start, rather than assuming quick approval, gives your project the best chance of staying on track.
What’s the most common reason residential projects run late?
Late selections and scope changes during construction are among the most frequent contributors to timeline blowouts. Both are largely preventable with clear decisions made in the planning stage before trades are on site.
