Strategic Local Government Asset Assessment Project (SLGAAP)

The Strategic Local Government Asset Assessment Project (SLGAAP) commenced in late 2019, with the Australian Government providing the NHVR with $8 million in grant funding over two years.

The funding was provided to assist local government road managers across Australia to undertake heavy vehicle assessments of on-road assets, such as bridges and culverts. 

The SLGAAP aims to improve heavy vehicle access by:

  • identifying current and potential key heavy vehicle routes on local roads
  • assisting local governments to better understand their road assets and make informed decision about heavy vehicles movements
  • creating a central database that contains information relating to the capacity of road assets and how different configurations of heavy vehicles can utilise the asset.

Road Manager Webinars

To support road managers in undertaking heavy vehicle assessments of their bridge and culvert assets, the NHVR ran a series of webinars from July-August 2021 for local government road managers to find out additional information on the project.

  • 6 July 2021, Webinar 1 - About the Strategic Local Government Asset Assessment Project (SLGAAP)
  • 8 July 2021, Webinar 2 - Basic Vehicle/ Bridge Interactions
  • 13 July 2021, Webinar 3 -  Asset Assessment Framework
  • 15 July 2021, Webinar 4 - Tier 1 Assessments
  • 20 July 2021, Webinar 5 - Engineering Reports on Assets
  • 22 July 2021, Webinar 6 - Vehicles and Route Assessment
  • 27 July 2021, Webinar 7 - Applying Conditions for Heavy Vehicle Access
  • 29 July 2021, Webinar 8 - NHVR Portal – Digital Asset Management
  • 3 August 2021, Webinar 9 - Pre-approvals for key route

Video recordings of the webinars as well as any slides or resources can be found on the project website here - SLGAAP Road Manager Webinars.

Project delivery

The Strategic Local Government Asset Assessment Project is being delivered in stages:

  • Pilot Phase - tests the assessment principles with pilot councils and jurisdictions
  • Round 1 Delivery - assessments will roll out to a larger number of councils based on adjustments made from the Pilot Phase

Pilot Phase

There were 12 Local Governments participating in the pilot:

  • New South Wales - Bega Valley Shire Council, Cessnock City Council, Muswellbrook Shire Council
  • Queensland - Central Highlands Regional Council, Isaac Regional Council, Mackay Regional Council, Toowoomba Regional Council
  • South Australia - Barossa Council
  • Victoria - Glenelg Shire Council, City of Greater Dandenong, Pyrenees Shire Council
  • Western Australia - Town of Port Hedland. 

Engineering assessments for 100 assets were completed, including Tier 1 and Tier 2 assessments. The asset results will be published in the NHVR Route Planner, giving road managers and industry the ability to select the best route for their vehicle movements.

Round 1 Delivery

Local councils were invited to express their interest in participating in Round 1 of the project in May 2020. Formal nominations were collected via the Asset Nomination Survey from 21 September 2020 to 2 October 2020, with an extension of the survey until 14 October 2020 (Round 1 is now closed).

Nationally, nearly 100 local governments submitted assets in SLGAAP Round 1, nominating more than 1,000 bridges and culverts for engineering assessment.

For any local governments who did not apply in Round 1 and would like to register interest in possible future rounds of asset assessments you can nominate for SLGAAP Future Rounds.

Project outcomes

Database for sharing road asset information

A database accessed via the NHVR Portal being developed to share road asset information, including bridge and culvert assessment reports. Also, the NHVR Portal Route Planner will include a layer to display asset information. It is intended that this asset information will improve heavy vehicle access application processes and enhance access decision-making.

Local Government Asset Assessment Toolkit

A Local Government Asset Assessment Toolkit will be available to support road managers in applying the Asset Assessment Framework Guide, providing a standard approach to heavy vehicle assessments.
