Module · Scheduling · Perth & WA
A wet week hits.
Right-click, and it’s handled.
Perth gives a reliable dry building stretch, then a wet winter that squeezes external work, with supply lead times to the west that run longer than the east coast. When a wet week or a late delivery moves a date, you right-click the task and reschedule, and the whole dependent chain moves with it. The affected vendor gets the new date as a two-way text conversation, the day is recorded automatically as a wet day, and Oryn prepares the Extension of Time ready to send to your client for signature. Oryn does the work, you act at speed. This is not a normal Gantt chart.

01 / What it does
What this feature does
This is the scheduling module of VIABUILD, the Construction Operating System for residential builders, set out for how a Perth build actually sequences. It is task-based with real dependencies, the connected core of residential construction scheduling. Lock a baseline when the plan is agreed and you can always see how far the job has drifted.
In practice Perth runs a strong seasonal split. Hot dry summers give a dependable window for the weather-exposed trades, while wet winters from around May to September hold up roofing, render and external paint, and materials freighted to the west can carry longer lead times. When a wet week or a late delivery lands you do not want to redraw a chart by hand. You want to right-click the affected task, reschedule, and have the whole chain move, the vendor told, the wet day logged and the Extension of Time drafted, in one move.
02 / Why it matters
Why builders need it
A wet week moves the externals
A wet winter run holds up roofing, render and paint, and everything behind them. Right-click, reschedule, and the dependent chain moves with it. No dragging bars one at a time.
The vendor hears by text
The affected subbie gets the new date as a two-way text conversation, not a notification buried in an app they never open. They reply straight back from the site.
Every wet day is captured
The delay is recorded automatically as a wet day, so the record that supports an Extension of Time is built as it happens, not reconstructed from memory months later.
The EOT is ready before you ask
Oryn prepares the Extension of Time from the wet day and the moved dates, ready for you to send to the client for signature. You act at speed.
Long lead times to the west
Materials freighted to WA can take longer to land. Schedule the long-lead items early and, when a delivery date moves, see the true cost across the whole run at a glance.
Milestones drive cash
Stage milestones line up with progress claims automatically. Keep the schedule current and the claims still follow the build, with no re-entry.
03 / The VIABUILD way
How VIABUILD handles it
Right-click, reschedule, and Oryn does the rest.
Build the schedule as tasks with real dependencies, set milestones for the stages that matter, including the ones that trigger a claim, and lock a baseline when the plan is agreed.
Then run the job. When a wet winter week or a late delivery moves a date, right-click the task and reschedule. The dependent chain moves with it and you see the new finish immediately against the baseline. The assigned vendor gets the new date as a two-way text message conversation and replies straight back, no portal to log into and no in-app notification they will never see. A weather delay is recorded automatically as a wet day.
From that wet day and the moved dates, Oryn prepares the Extension of Time, ready for you to send to the client for signature. Marking a stage done is still a completion, not a sign-off, the distinction between approvals and completions that keeps the program honest. On site the same dates show up in ViaSite, and because WA builders carry home indemnity insurance obligations, a schedule that stays current makes those handover dates easier to hold.
- Right-click reschedule, the whole dependent chain moves
- Vendor notified by two-way text, not an in-app alert
- A weather delay recorded automatically as a wet day
- Oryn prepares the Extension of Time for client signature
- Baseline tracking to measure seasonal drift
- The same dates flow through to progress claims and the field
- Not a normal Gantt chart
04 / The workflow
How it runs, step by step
- 01
Build the sequence
Lay out tasks and dependencies the way a Perth build runs, keeping exposed work in the dry window and ordering long-lead items early.
- 02
Lock a baseline
Capture the agreed plan so you can measure seasonal drift against it later.
- 03
Right-click to reschedule
When a wet week or a late delivery moves a date, reschedule and the whole dependent chain moves with it.
- 04
The vendor is told
The affected subbie gets the new date as a two-way text conversation and replies from site. No portal, no in-app notification.
- 05
The wet day is logged
A weather delay is recorded automatically as a wet day, building the record behind any Extension of Time.
- 06
Oryn prepares the EOT
The Extension of Time is drafted from the wet day and the moved dates, ready to send to the client for signature.
- 07
See the drift
Compare current vs baseline to know exactly how far you have moved, and act early.
05 / FAQ
Common questions.
You right-click the affected task and reschedule. The whole dependent chain moves with it, the assigned vendor gets the new date as a two-way text conversation, a weather delay is recorded automatically as a wet day, and Oryn prepares the Extension of Time ready for you to send to the client for signature. One move, not an afternoon of admin.
By a two-way text message conversation. The vendor gets the new date as a text and replies straight back to the task, so the conversation lives next to the work. There is no portal to log into, no app to install and no in-app notification they will never open.
Yes. When a weather delay is logged as a wet day, Oryn prepares the Extension of Time from that record and the moved dates, ready for you to send to the client for signature. The supporting record is built as the delay happens rather than reconstructed later. See the guide on extensions of time and delays for the wider process.
Yes. Stage milestones in the schedule line up with stage-based progress claims, so as the build hits each stage your claims follow the work with no double entry, even when a wet week or a late delivery has moved the program.
