Managing vegetation contractors needs more than emails and invoices

Councils need to know what work was assigned, what was completed, when it happened, who did it, what evidence was captured and whether the tree record was updated.

Why contractor evidence matters

Contractors do most of the physical work that touches public trees. Without clear proof of work, the council pays invoices for activity it cannot describe in detail and cannot point to in the asset record.

Work allocation and scope clarity

Useful contractor management starts before site work. The work order should make scope unambiguous: which trees, what action, what timeframe and what evidence is required at closeout.

Photos, notes, forms and GPS

Evidence should be structured. Free-text notes are useful in addition, not in place of, photos and structured activity records. GPS at the time of capture is increasingly available on field devices and should be a default expectation.

Compliance and safety evidence

Traffic management plans, site hazard forms, SWMS where applicable, and other compliance evidence should attach to the job and be retrievable later. The tree record should reference where they live.

Updating the council record after contractor activity

The most important closeout step is the easiest to miss. Each contractor visit should result in an updated tree record — new latest known condition, work performed, contractor identity, evidence attached and next review date if relevant.

Workflow

Contractor work flow that updates the tree record

From council request through to a record that reflects the completed activity.

  1. Step 01

    Council request

    Resident, inspection or program-driven.

  2. Step 02

    Work order

    Scope, tree, timeframe, evidence required.

  3. Step 03

    Contractor allocation

    Crew assigned, hazards reviewed.

  4. Step 04

    Site work

    Activity performed and documented.

  5. Step 05

    Evidence capture

    Photos, forms, GPS, notes.

  6. Step 06

    Council review

    Closeout confirmed and approved.

  7. Step 07

    Record updated

    Tree record reflects the work.

  8. Step 08

    Report / invoice

    Closeout supports payment and audit.

A practical standard

Minimum standard councils can adopt

A workable proof-of-work standard that supports payment, defensibility and register quality at the same time.

Standard

Identification

Every completed job lists the trees it touched, by ID or GPS plus photo of immediate surroundings.

Standard

Activity

Every tree touched has a structured activity record using a short agreed list of work types.

Standard

Evidence

Every tree touched has before and after photos, with site forms and compliance records attached to the job.

Standard

Closeout

Every completed job updates the latest known condition on each tree, with recommended next action where relevant.

FAQ

Frequently asked questions

What proof of work should councils expect from vegetation contractors?

Identification (asset ID where possible, otherwise GPS plus context photo), structured activity (from an agreed list of work types), before and after photos with EXIF metadata intact, compliance evidence (TMP, SWMS where applicable), and an updated latest known condition for each tree touched.

Should contractor evidence attach to the job or the tree?

Both, but the tree record is the more important destination. Job folders close and get archived. Tree records persist. When evidence only attaches to the job, two years later it is hard to find the photos for a specific tree without reopening the archive.

How should contractors identify trees if there is no asset ID?

GPS at the time of capture plus a wide context shot showing immediate surroundings (house numbers, signage, landmarks). Address-and-side-of-street notation is useful as a fallback but less reliable than GPS plus photo.

What does "closeout" mean in this context?

The set of actions at the end of a contractor visit that update the council's tree record: new latest known condition, structured activity recorded, contractor and date attached, evidence linked to the tree, and recommended next action where relevant. Closeout that only updates the invoice, not the tree record, means the register learns nothing from the work.

What if our council currently accepts less than this standard?

Most councils are quietly tightening these expectations. The closeout standard above is increasingly what councils expect for renewal. Contractors who already operate at that level tend to retain and grow council work. Contractors who do not increasingly find renewal harder.
