1.0 Pre-audit

Photo of entire asset & surroundings

Asset function

Asset Function: (a general description)
- location
- catchment
- key features eg, concrete apron to assist in sediment removal
- predominant plant species (if present)
- depth
- current condition

Type of catchment

Type of catchment:
eg. pavement only, grassed, garden beds, residential, industrial, other

Location of swale

How would you classify this location?
eg. road reserve, active open space, retarding basin, private property

Traffic conditions

This is useful to plan maintenance and repairs
eg. Low traffic - residential street, high traffic - major road

Previous inspections

2.0 Surrounds

Independent structures (part of asset)

This section is for structures that are included as part of the asset. Many signs, bollards etc will have their own asset ID.

Using the condition assessment manual as a guide, rate the individual component. Take photographs to corroborate the rating, and make note of the material and any other important points in the description, including the number of components (if multiple).

3.0 Civil components

Civil structures

Using the condition assessment manual as a guide, rate the individual component. Take photographs to corroborate the rating, and make note of the material and any other important points in the description, including the number of components (if multiple).

Inlet
Evidence of condition

Description of condition

A swale may have multiple inlets. They could be pipes, wide concrete aprons, or regular breaks in a kerb. Photograph all inlets and consider the overall condition of them as a group.

Outlet (underdrain)
Evidence of condition

Description of condition

A bioretention swale will have an underdrain as its treatment outlet. A partial observation can be made by checking through an inspection opening (if present) or by looking into pit associated with the swale. Only a limited assessment will be able to be made but try to determine if water is flowing/can flow through it.

If the swale is conveyance only, check N/A and move to the next question.

Overflow outlet
Evidence of condition

Description of condition

In either a conveyance or bioretention swale, this is the outlet at the terminating end of the swale, if present. It may be a pipe, side entry pit, grate, or entry to a waterway.

High flow bypass
Evidence of condition

Description of condition

This will not be present for all assets. Small assets may have a defined bypass channel or pipe to prevent large flows from entering them.

Access to structures
Evidence of condition

Description of condition

Access for vehicles and/or maintenance crews must be available to all structures. If not, please highlight in audit results and prioritise rectification works.

4.0 Basin

Surfaces

Using the condition assessment manual as a guide, rate the individual component. Take photographs to corroborate the rating, and make note of the material and any other important points in the description, including the number of components (if multiple).

Vegetation
Grass/turf
Evidence of condition

Description of condition

Treatment vegetation
Evidence of condition

Description of condition

This is the vegetation within the limits of the rain garden surface.

Other vegetation/grasses/trees
Evidence of condition

Description of condition

Hydraulic conductivity

Is hydraulic conductivity testing required?

Rate of hydraulic conductivity (field test)

If condition of surface or vegetation is fair to poor due to too much or too little water for a bioretention swale, the filter media may be compromised. Field testing can give an indication of whether this is part of the problem.

5.0 Rapid Assessment

Asset works priority

Visibility

Visibility: Examples of high visibility are shopping precincts, landscaped public open space, general high traffic areas.

Catchment

High catchment priority (if able to be determined) includes catchments that outfall directly to the bays, or are upstream of sensitive areas

Treatment

Treatment: High asset priority (if able to be determined) would include an asset that is the lone treatment in a catchment, or performs a significant proportion of treatment within a catchment

Surrounds

Surrounds: Examples of low priority are assets in disturbed areas such as residential streets with ongoing construction that will stymie maintenance efforts

Initial assessment

Are there any elements or issues that the assessors consider to be a risk to health and safety? Please provide a full description

Health and safety concerns?

Health and Safety issues

Corrective maintenance tasks required (Not planned)

Other maintenance

Overall assessment category

Final notes

Based on your observation of the total function of the asset and your individual condition ratings of components, provide an overall rating for the asset. The Condition Assessment Manual contains general guidance.
