    3. Technique will ensure the infrastructure constructed will meet Council’s infrastructure design life.
    4.  Technique will ensure that the infrastructure constructed will meet Council’s current levels of service or whole of life costs.
    5. Technique utilises Council’s approved materials list.
  3. Consultation, with Council, shall be undertaken prior to a full alternative design being undertaken to ensure that the alternative design is one that Council considers will meet its asset management and service delivery requirements
