Hints and tips

  • Experience and Resources – in 80 per cent of cases the tenderer does not communicate adequately their experience and resources to deliver the task, failing to give the tender panel confidence in their capability to actually deliver on time and budget. Experience in similar projects and demonstrated resources to deliver are vital to score well in tender assessments. Council requires specific details under this criteria, not just basic details.
  • Appreciation of Task – in 60 per cent of cases the tenderer fails to adopt and confirm general methodology demonstrating an appreciation of the task and/or completion of the whole works. Council projects in general have been established and designed via extensive community consultation and experts inputs, and in some instances neighbouring landowner consents, so in many cases the task is of importance to the community and environmental or specialised conditions must be adhered to by tenderers.
  • Timeframe – in 50 per cent of cases the tenderer does not adequately confirm the project or goods can be delivered as per the timeline scheduled in the tender documents. Most major procurements with council are open to public scrutiny, so tenders should demonstrate by providing a detailed project plan of the timeline breakdown, including estimated milestone dates. Providing timelines beyond project parameters rarely is accepted as projects are often funded by state or federal government grants and seasonal conditions that generally tighten the window of opportunity. In many cases being innovative and demonstrating a shortened timeline within realistic parameters can be quite an advantage in the assessment scoring, as this minimises disruption to our communities.
  • Local Business Support – in 50 per cent of cases the tenderer does not demonstrate the use of local businesses and/or local job opportunities within the project supply chain. Federal and State governments are increasingly stipulating Local Participation Plans on major projects, and local procurement is a priority of council (in City of Onkaparinga local businesses get a 10 per cent weighted criteria scoring benefit). For tenderers based outside of Onkaparinga, demonstrated use of local suppliers for goods and services is desired.
  • Special conditions - In some tenders emerging project requirements can be specified such as circular economy use of recycled products, sustainable whole of life costs, and sometimes Indigenous economic outcomes.
