Quality Assurance

Having worked on numerous Sydney Water projects and closely with Sydney Water systems, Killard Infrastructure maintains efficient and transparent accreditation to AS/NZS ISO 9001:2015 and ISO 14001:2015 with an Integrated Management System in Safety, Quality and Environment as well as AS/NZS 4801:2001 for the scope of excavation, sewer, water, and drainage services. The Killard Infrastructure management and quality team ensures all projects we undertake adhere to our internal systems. We demand the highest quality work from ourselves while maintaining a relaxed and upbeat work environment.

Work Health and Safety

For projects, a specific safety management plan is developed on a contract by contract basis, based on Killard Infrastructure’s safety management template which meets the requirements of AS/NZS 4801:2001.

In accordance with AS/NZS 4801, the safety management plan addresses:

  • Identification of hazards specific to theproject
  • Assessment of risks associated with thosehazards
  • Safety measures and controls for the hazards andrisks
  • Nomination of responsible persons and assignment ofroles

Killard has developed a method to ensure proper compliance and consistent implementation of safety plans across all crews and locations through the development of its site folder packs.

Site specific folder packs include a series of checklists that crews must complete each day before commencing work.  This demonstrates that they have identified hazards and risks specific to their sites and tasks and confirms that they have implemented obligatory controls. Each crew member is required to sign on daily.
