Hints and tips


Value for money is critical and this must include whole of life costs, overheads, adjustments and assumptions. Council is not obliged to accept the lowest priced tender. Price will be considered alongside other qualitative criteria to ensure the best overall outcome for all parties. Sometimes budget is disclosed where cost of the project is limited. In this case tenders exceeding the budget are rarely accepted.


Tenderers need to demonstrate their experience with work of a similar nature, scale, cost and complexity. Include key details such as costs, duration, results, images and referees.

Capacity & Resources

Tenderers need to demonstrate their capacity and describe specific resources needed to deliver the project. This may include organisational charts, staff CV’s, subcontractor details, equipment registers, forecast of future work and any other relevant information demonstrating capacity.


Tenderers need to submit a methodology or program demonstrating how the project objectives will be accomplished. This should include a Gannt chart where relevant, with defined stages and milestones. Provision of other detail such as systems, processes and techniques will be of benefit. Timelines beyond defined project parameters are rarely accepted. A realistic but concise timeframe will often result in favourable scoring.

Local Business Support

Local procurement and supporting our local businesses are a priority of the City of Onkaparinga. Suppliers located within the City of Onkaparinga may get up to 10 percent weighted criteria scoring benefit. Demonstrated use of local suppliers, materials and labour will be well received.

Mandatory Criteria

Tenderers must demonstrate compliance with the mandatory criteria specified in the request documents. Mandatory Criteria generally include:

  • Public Liability Insurance cover for $20 million;
  • Return to Work SA registration; and
  • Work Health & Safety Management System.
  • Relevant Trade Registration or Licence

Plus, any other criteria depending on the nature of the contract.

Special Conditions

Some contracts may include special conditions which are included as an appendix with the conditions of contract document.

Special conditions may include customised requirements or constraints outside of standard contractual terms and conditions and these should be reviewed carefully.
