Build Sequence Schedule
A 42-task Gantt chart in Excel, built from the real NSW owner-builder chronological build order — not a generic project-builder template with the serial numbers filed off.
Why it runs longer than a builder's schedule
Most downloadable construction schedules assume a builder with trades booked back-to-back. You're queuing for the same subcontractors as everyone else, usually without a builder's standing relationships. This one starts from a realistic project-builder baseline per task, then applies an editable multiplier per task — heavier on real bottlenecks like brickwork, lighter on tasks you can do yourself whenever you have time, like painting or landscaping.
Owner-Builder
40 wks
Project-Builder Baseline
33 wks
Both are editable estimates in the spreadsheet, not fixed facts — replace the duration and multiplier for each task with real quotes as you get them.
Simplified stage view
The five stages below match the Build Roadmap. This bar simplifies the schedule into non-overlapping stage blocks for a big-picture read — the spreadsheet has the real, overlapping, task-by-task detail (42 tasks across 52 weeks) plus the mandatory NSW critical-stage inspections.
- 0 · Before You StartWeeks 1–13
- 1 · Footings & SlabWeeks 14–19
- 2 · FrameWeeks 20–27
- 3 · Lock-upWeeks 28–33
- 4 · Fit-out & FinalWeeks 34–39
What's in the spreadsheet
- 0142 tasks in real chronological order, from permit lodgement to Occupation Certificate.
- 02The 4 mandatory NSW critical-stage inspections, flagged and highlighted on the Gantt bars.
- 03Two editable duration columns per task — a project-builder baseline and an owner-builder multiplier — so you can see exactly where your own build will run long.
- 04A formula-driven Gantt: change a duration or multiplier and the whole schedule recalculates.
- 05A Read Me tab documenting every source and assumption.
