We need information on two laws in Australia:
1. what are the requirements regarding construction dust in Australia, we cut concrete dry, and it creates dust. We vacuum 90% of it, but about 10% collects on the ground and we vacuum it up. What do we need to know from an environmental perspective.
2. the USA has the Americans with Disabilities Act. What's the Australian equivalent to that law? We need details on whether or not the sidewalks have to be kept up for wheelchairs to pass on them easily. For the ADA they have a "change in level" requirement, does that exist in AUS?
