Project Challenges

  • Dust suppression

We recognized that management of dust is important especially in the drier summer months. It can be unpleasant living in close proximity to a construction site, and we’ve worked hard to minimise the impacts of dust overflow on surrounding residents. Some of the methods used to minimize this included:

  • Hydromulch and Dustex

  • Consistent scheduling of Water carts and cannons to wet down access tracks and surrounding site

  • Efficient and effective dust monitoring to ensure construction dust is kept within the prescribed limits.

  • Working with prevailing winds whenever possible which minimized opportunities for dust to blow off and onto surrounding properties and businesses.
