Noise barrier cost calculator

This calculator provides an estimate of the supply and installation costs of noise barriers, intended for use when comparing mitigation options during an assessment under NZS 6806. More accurate estimations should be made by specialists when required for project costing purposes.

If noise barriers are erected as a standalone project (for example, when retrofitting noise walls) there will be additional project costs that exceed these supply and installation costs. For example, additional costs may include: design and project management, modifications to existing safety barriers and stormwater systems affected by the noise walls, addressing contaminated land issues, planting requirements and traffic management. Maintenance costs associated with noise barriers should also be considered for project costing purposes.
