Foreign bidders

• A South African representative or agent must submit written proof of authorisation from the principal; without it the bid is disqualified.

• An email successfully sent to the bidder counts as delivery one day after the date of submission.
• Where the General Bid Conditions conflict with the RFX, the RFX prevails.

Validity

• Bids must stay valid for the validity period requested in the RFP. If Transnet requests an extension, no aspect of the bid may change unless the change is a direct and unavoidable result of the extension.

Performance and default

• If a bidder whose bid is accepted fails to sign a formal contract when called upon, accept an order, provide satisfactory security, or meet any condition Transnet imposes, Transnet may accept another bid or call for fresh bids and recover any extra cost from the defaulting bidder.
• Transnet does not commit to buying a fixed quantity; the successful bidder must supply whatever is ordered on or before the contract expiry date.
• Transnet accepts no liability for stock specially ordered or carried by the bidder to meet contract requirements. Annual quantities given in the bid documents are estimates only.
• The delivery period is governed by the Terms and Conditions of Contract, and the supplier may have to submit periodic progress reports.
• In emergencies the supplier has first right of refusal; if it cannot meet the critical delivery period, Transnet may buy outside the contract, and the failure-to-perform provisions do not apply.

Security

• When called upon, the successful bidder must provide a Deed of Suretyship from an approved bank, building society, insurance or guarantee corporation operating in South Africa. No other guarantee form is accepted.

Payment

• Payment conditions are set out in the Terms and Conditions of Contract and bid prices must be based on them. Bidders must first tender strictly on those conditions; failure may stop the bid from further consideration.
• Alternative payment or financing proposals may be submitted with full particulars and are evaluated on financial merit at adjudication.
• The successful supplier may have to provide a guarantee for advance payments.
