Construction projects generate changing material and waste flows. Environmental audit evidence can connect the site's identified impacts with purchasing, storage, contractor arrangements and records of disposal.

Questions to follow in an audit

  • How are significant waste streams identified for this project?
  • Who checks the suitability of the waste contractor?
  • How are discrepancies in collections or transfer records investigated?

Connect the records with practice
