Prequalification for Infrastructure and Transport

Prequalification is a system which ensures that only appropriately skilled and experienced companies are permitted to submit tenders to the Department in certain categories of contract.

To become prequalified, a company must demonstrate that they have the experience, technical capacity, available resources and management systems necessary to competently undertake the work. A company may apply for prequalification in any category at any time. Prequalification is available at various levels that reflect the complexity and value of contracts that a company will be permitted to tender for. When a contract is advertised, the Request for Tender will specify the level of prequalification required.

Prequalification does not replace effective post-tender assessment or sound contract management. It only represents a right to submit a tender or to be considered for a select tender list. For each tender assessment, the Department will take into account factors such as proposed methodology, resources allocated and past company performance when determining which company will be successful.

Prequalification at the higher level will automatically qualify a contractor to tender for work in a lower category. For contracts of high value or complexity, a pre-registration process (i.e. seeking Expressions of Interest) instead of, or in addition to, prequalification may apply.
