EXAMPLE AT A GLANCE
This fictional Mackay, Queensland tree root barrier installation example contains 7 itemised costs totalling A$6,460.78. Its app-exported PDF uses the exact metric quantities and AUD rates in the table, with scope assumptions and exclusions explained below.
Project scope: One garden path edge
Install a specified root barrier along a garden path edge after confirming the tree and excavation constraints, then reinstate the disturbed surface.
This original fictional example is set in Mackay, Queensland. Harbour & Gum Projects and Alex Morgan are made-up parties. The matching Australian guide explains which measurements, product decisions and site conditions turn this brief into a client-ready quote.

Itemised tree root barrier installation costs
These 7 AUD lines reproduce the native app export. Careful trench excavation is measured as 16.76 m; Barrier material allowance uses 18.29 m. Some lines are measured work while others are a product or site-task allowance. Read the unit before reusing the structure for a different job.
| Work item | Quantity | Unit rate | Amount |
|---|---|---|---|
| Site and tree review allowance | 1 job | A$310.20 | A$310.20 |
| Surface protection and lift | 1 job | A$253.80 | A$253.80 |
| Careful trench excavation | 16.76 m | A$129.50 | A$2,170.42 |
| Barrier material allowance | 18.29 m | A$102.00 | A$1,865.58 |
| Joints and anchors | 1 job | A$296.10 | A$296.10 |
| Barrier placement labour | 16.76 m | A$55.50 | A$930.18 |
| Backfill and surface reinstatement | 1 job | A$634.50 | A$634.50 |
| Illustrative total | A$6,460.78 | ||
Product selection and installation should be clear from the descriptions. Confirm delivery, fixings, preparation, waste and any specialist trade responsibility for the actual job rather than assuming each allowance covers them.
Check the arithmetic
Careful trench excavation: 16.76 m × A$129.50 = A$2,170.42. Barrier material allowance: 18.29 m × A$102.00 = A$1,865.58. All other lines use the same quantity-by-rate calculation and sum to A$6,460.78. Every fixture line lands on an exact cent, so the native PDF subtotal equals the displayed table total.
Measurement to check: Measure barrier run, required depth and distance from the trunk; confirm tree protection constraints locally. Selection to check: Identify barrier product, joining strips and reinstatement material separately. The PDF uses a 0% tax input only to make its fictional arithmetic visible. Confirm the GST treatment that applies to the actual job and set your own markup before sharing a client quote.
Assumptions and exclusions
Agree a safe excavation method near roots before digging.
Outside this stated scope: No tree removal, arborist design or guaranteed control of all future roots.
Major roots or utilities in the trench may require a different route and professional review. A changed condition should lead to a newly measured quantity, revised allowance or separately agreed task. Keep the client informed of the changed figure before producing another PDF.
